Controlling CUBRID Service¶

The following cubrid utility syntax shows how to control services registered in the configuration file. One of the following can be specified in <command>.

cubrid service <command>
<command>: {start|stop|restart|status}

• start: start services.
• stop: stop services.
• restart: restart services.
• status: check status.

No additional options or arguments are required.

Controlling Database Server¶

The following cubrid utility syntax shows how to control database server process.

<command>: {start|stop|restart|status}

One of the following can be specified in <command>:

• start: start a database server process.
• stop: stop a database server process.
• restart: restart a database server process.
• status: check status of a database server process.

Every command except status must have a database name as an argument.

Controlling Broker¶

cubrid broker <command>
<command>: start
           |stop
           |restart
           |status [options] [broker_name_expr]
           |acl {status|reload} broker_name
           |on <broker_name> |off <broker_name>
           |reset broker_name
           |info

• stop: stop broker processes.
• restart: restart broker processes.
• status: check status of broker processes.
• acl: limit broker access.
• on/off: enable/disable the specified broker.
• reset: reset the connection to broker.
• info: display the broker configuration information.

Controlling CUBRID Manager Server¶

To use the CUBRID Manager, the Manager server must be running where database server is running. The following cubrid utility syntax shows how to control the CUBRID Manager processes.

cubrid manager <command>
<command>: {start|stop|status}

• start: start manager server processes.
• stop: stop manager server processes.
• status: check the status of manager processes.

Controlling CUBRID HA¶

The following cubrid heartbeat utility syntax shows how to use CUBRID HA. One of the following can be specified in command.

cubrid heartbeat <command>
<command>: {start|stop|copylogdb|applylogdb|reload|status}

• start: start HA-related processes.
• stop: stop HA-related processes.
• copylogdb: start or stop copylogdb process.
• applylogdb: start or stop applylogdb process.
• reload: reload information on HA configuration.
• status: check HA status.

For details, see cubrid heartbeat Utility.

Registering Services¶

You can register database servers, CUBRID brokers, CUBRID Manager(s) or CUBRID HA as CUBRID service in the configuration file ( cubrid.conf ). To register services, you can input for each server, broker, manager or heartbeat as a parameter value, and it is possible to input several values by concatenating them in comma(,).

If you do not register any service, only master process is registered by default. It is convenient for you to view status of all related processes at a glance or start and stop the processes at once with the cubrid service utility once it is registered as CUBRID service.

For details on CUBRID HA configuration, see Registering HA to cubrid service.

The following example shows how to register database server and broker as service in the cubrid.conf file and enable databases ( demodb and testdb ) to start automatically at once when CUBRID server starts running.

# cubrid.conf
...

[service]

# The list of processes to be started automatically by 'cubrid service start' command
# Any combinations are available with server, broker, manager and heartbeat.
service=server,broker

# The list of database servers in all by 'cubrid service start' command.
# This property is effective only when the above 'service' property contains 'server' keyword.
server=demodb,testdb

Starting Services¶

In Linux environment, you can enter the code below to start CUBRID after installation. If no server is registered in the configuration file, only master process (cub_master) runs by default.

In the Windows environment, the code below is normally executed only if a user with system permission has logged in. An administrator or general user can start or stop the CUBRID server by clicking its icon on the taskbar tray.

% cubrid service start

@ cubrid master start
++ cubrid master start: success

The following message is returned if master process is already running.

% cubrid service start

@ cubrid master start
++ cubrid master is running.

The following message is returned if master process fails to run. The example shows that service fails to start due to conflicts of the cubrid_port_id parameter value specified in the cubrid.conf file. In such a case, you can resolve the problem by changing the port. If it fails to start even though no port is occupied by process, delete /tmp/CUBRID1523 file and then restart the process.

% cubrid service start

@ cubrid master start
cub_master: '/tmp/CUBRID1523' file for UNIX domain socket exist.... Operation not permitted
++ cubrid master start: fail

After registering service as explained in CUBRID Services, enter the code below to start the service. You can verify that database server process and broker as well as registered demodb and testdb are starting at once.

% cubrid service start

@ cubrid master start
++ cubrid master start: success
@ cubrid server start: demodb

This may take a long time depending on the amount of restore works to do.
CUBRID 10.1

++ cubrid server start: success
@ cubrid server start: testdb

This may take a long time depending on the amount of recovery works to do.
CUBRID 10.1

++ cubrid server start: success
@ cubrid broker start
++ cubrid broker start: success

Stopping Services¶

Enter code below to stop CUBRID service. If no services are registered by a user, only master process stops and then restarts.

% cubrid service stop
@ cubrid master stop
++ cubrid master stop: success

Enter code below to stop registered CUBRID service. You can verify that server process, broker process, and master process as well as demodb and testdb stop at once.

% cubrid service stop
@ cubrid server stop: demodb

Server demodb notified of shutdown.
This may take several minutes. Please wait.
++ cubrid server stop: success
@ cubrid server stop: testdb
Server testdb notified of shutdown.
This may take several minutes. Please wait.
++ cubrid server stop: success
@ cubrid broker stop
++ cubrid broker stop: success
@ cubrid master stop
++ cubrid master stop: success

Restarting Services¶

Enter code below to restart CUBRID service. If no services are registered by a user, only master process stops and then restarts.

% cubrid service restart

@ cubrid master stop
++ cubrid master stop: success
@ cubrid master start
++ cubrid master start: success

Enter code below to restart registered CUBRID service. You can verify that server process, broker process, and master process as well as demodb and testdb stop and then restart at once.

% cubrid service restart

@ cubrid server stop: demodb
Server demodb notified of shutdown.
This may take several minutes. Please wait.
++ cubrid server stop: success
@ cubrid server stop: testdb
Server testdb notified of shutdown.
This may take several minutes. Please wait.
++ cubrid server stop: success
@ cubrid broker stop
++ cubrid broker stop: success
@ cubrid master stop
++ cubrid master stop: success
@ cubrid master start
++ cubrid master start: success
@ cubrid server start: demodb

This may take a long time depending on the amount of recovery works to do.

CUBRID 10.1

++ cubrid server start: success
@ cubrid server start: testdb

This may take a long time depending on the amount of recovery works to do.

CUBRID 10.1

++ cubrid server start: success
@ cubrid broker start
++ cubrid broker start: success

Managing Service Status¶

The following example shows how to check the status of master process and database server registered.

% cubrid service status

@ cubrid master status
++ cubrid master is running.
@ cubrid server status

Server testdb (rel 10.1, pid 31059)
Server demodb (rel 10.1, pid 30950)

@ cubrid broker status
% query_editor
----------------------------------------
ID   PID   QPS   LQS PSIZE STATUS
----------------------------------------
 1 15465     0     0 48032 IDLE
 2 15466     0     0 48036 IDLE
 3 15467     0     0 48036 IDLE
 4 15468     0     0 48036 IDLE
 5 15469     0     0 48032 IDLE

% broker1 OFF

@ cubrid manager server status
++ cubrid manager server is not running.

The following message is returned if master process has stopped.

% cubrid service status
@ cubrid master status
++ cubrid master is not running.

cubrid Utility Logging¶

CUBRID supports a logging feature about cubrid utility's running result.

Logging contents

The following contents are written to the $CUBRID/log/cubrid_utility.log file.

• All commands through cubrid utilities: only usage, version and parsing errors are not logged.
• Execution results by cubrid utilities: success/failure.
• An error message when failure.

Log file size

A size of cubrid_utility.log file is expanded by the size specified by error_log_size parameter in cubrid.conf; if this size is enlarged as the specified size, it is backed up as the cubrid_utility.log.bak file.

Log format

<time> (cubrid PID) <contents>

The following is an example of printing the log file.

13-11-19 15:27:19.426 (17724) cubrid manager stop
13-11-19 15:27:19.430 (17724) FAILURE: ++ cubrid manager server is not running.
13-11-19 15:27:19.434 (17726) cubrid service start
13-11-19 15:27:19.439 (17726) FAILURE: ++ cubrid master is running.
13-11-19 15:27:22.931 (17726) SUCCESS
13-11-19 15:27:22.936 (17756) cubrid service restart
13-11-19 15:27:31.667 (17756) SUCCESS
13-11-19 15:27:31.671 (17868) cubrid service stop
13-11-19 15:27:34.909 (17868) SUCCESS

However, in Windows, some cubrid commands are executed through a service process; therefore, a duplicated information can be displayed again.

13-11-13 17:17:47.638 ( 3820) cubrid service stop
13-11-13 17:17:47.704 ( 7848) d:\CUBRID\bin\cubrid.exe service stop --for-windows-service
13-11-13 17:17:56.027 ( 7848) SUCCESS
13-11-13 17:17:57.136 ( 3820) SUCCESS

And, in Windows, a process run through the service process cannot print out an error message; therefore, for error messages related to the service start, you should definitely check them in the cubrid_utility.log file.

Starting Database Server¶

The following example shows how to run demodb server.

% cubrid server start demodb

@ cubrid server start: demodb

This may take a long time depending on the amount of recovery works to do.

CUBRID 10.1

++ cubrid server start: success

If you start demodb server while master process has stopped, master process automatically runs at first and then a specified database server runs.

% cubrid server start demodb

@ cubrid master start
++ cubrid master start: success
@ cubrid server start: demodb

This may take a long time depending on the amount of recovery works to do.

CUBRID 10.1

++ cubrid server start: success

The following message is returned while demodb server is running.

% cubrid server start demodb

@ cubrid server start: demodb
++ cubrid server 'demodb' is running.

cubrid server start runs cub_server process of a specific database regardless of HA mode configuration. To run database in HA environment, you should use cubrid heartbeat start.

Stopping Database Server¶

The following example shows how to stop demodb server.

% cubrid server stop demodb

@ cubrid server stop: demodb
Server demodb notified of shutdown.
This may take several minutes. Please wait.
++ cubrid server stop: success

The following message is returned while demodb server has stopped.

% cubrid server stop demodb

@ cubrid server stop: demodb
++ cubrid server 'demodb' is not running.

cubrid server stop stops cub_server process of a specific database regardless of HA mode configuration. Be careful not to restart the database server or occur failover. To stop database in HA environment, you should use cubrid heartbeat stop .

Restarting Database Server¶

The following example shows how to restart demodb server. demodb server that has already run stops and the server restarts.

% cubrid server restart demodb

@ cubrid server stop: demodb
Server demodb notified of shutdown.
This may take several minutes. Please wait.
++ cubrid server stop: success
@ cubrid server start: demodb

This may take a long time depending on the amount of recovery works to do.

CUBRID 10.1

++ cubrid server start: success

Checking Database Server Status¶

The following example shows how to check the status of a database server. Names of currently running database servers are displayed.

% cubrid server status

@ cubrid server status
Server testdb (rel 10.1, pid 24465)
Server demodb (rel 10.1, pid 24342)

The following example shows the message when master process has stopped.

% cubrid server status

@ cubrid server status
++ cubrid master is not running.

Limiting Database Server Access¶

To limit brokers and the CSQL Interpreter connecting to the database server, configure the parameter value of access_ip_control in the cubrid.conf file to yes and enter the path of a file in which the list of IP addresses allowed to access the access_ip_control_file parameter value is written. You should enter the absolute file path. If you enter the relative path, the system will search the file under the $CUBRID/conf directory on Linux and under the %CUBRID%\conf directory on Windows.

The following example shows how to configure the cubrid.conf file.

# cubrid.conf
access_ip_control=yes
access_ip_control_file="/home1/cubrid1/CUBRID/db.access"

The following example shows the format of the access_ip_control_file file.

[@<db_name>]
<ip_addr>
...

• <db_name>: The name of a database in which access is allowed
• <ip_addr>: The IP address allowed to access a database. Using an asterisk (*) at the last digit means that all IP addresses are allowed. Several lines of <ip_addr> can be added in the next line of the name of a database.

To configure several databases, it is possible to specify additional [@<db_name>] and <ip_addr>.

Accessing any IP address except localhost is blocked by server if access_ip_control is set to yes but ip_control_file is not configured. A server will not run if analyzing access_ip_control_file fails caused by incorrect format.

The following example shows access_ip_control_file.

[@dbname1]
10.10.10.10
10.156.*

[@dbname2]
*

[@dbname3]
192.168.1.15

The example above shows that dbname1 database allows the access of IP addresses starting with 10.156; dbname2 database allows the access of every IP address; dbname3 database allows the access of an IP address, 192.168.1.15, only.

For the database which has already been running, you can modify a configuration file or you can check the currently applied status by using the following commands.

To change the contents of access_ip_control_file and apply it to server, use the following command.

cubrid server acl reload <database_name>

To display the IP configuration of a server which is currently running, use the following command.

cubrid server acl status <database_name>

Database Server Errors¶

Database server error processes use the server error code when an error has occurred. A server error can occur in any task that uses server processes. For example, server errors may occur while using the query handling program or the cubrid utility.

Checking the Database Server Error Codes

• Every data definition statement starting with #define ER_ in the $CUBRID/include/dbi.h file indicate the server error codes.
• All message groups under "$set 5 MSGCAT_SET_ERROR" in the CUBRID/msg/en_US (in Korean, ko_KR.eucKR or ko_KR.utf8)/cubrid.msg $ file indicates the server error messages.

When you write a C code with CCI driver, we recommend you to write a code with an error code name than with an error code number. For example, the error code number for violating the unique key is -670 or -886, but users can easily recognize the error when it is written as ER_BTREE_UNIQUE_FAILED or ER_UNIQUE_VIOLATION_WITHKEY.

However, when you write a JAVA code with JDBC driver, you have to use error code numbers because "dbi.h" file cannot be included into the JAVA code. For JDBC program, you can get an error number by using getErrorCode() method of SQLException class.

$ vi $CUBRID/include/dbi.h

#define NO_ERROR                                       0
#define ER_FAILED                                     -1
#define ER_GENERIC_ERROR                              -1
#define ER_OUT_OF_VIRTUAL_MEMORY                      -2
#define ER_INVALID_ENV                                -3
#define ER_INTERRUPTED                                -4
...
#define ER_LK_OBJECT_TIMEOUT_SIMPLE_MSG              -73
#define ER_LK_OBJECT_TIMEOUT_CLASS_MSG               -74
#define ER_LK_OBJECT_TIMEOUT_CLASSOF_MSG             -75
#define ER_LK_PAGE_TIMEOUT                           -76
...
#define ER_PT_SYNTAX                                -493
...
#define ER_BTREE_UNIQUE_FAILED                      -670
...
#define ER_UNIQUE_VIOLATION_WITHKEY                 -886
...
#define ER_LK_OBJECT_DL_TIMEOUT_SIMPLE_MSG          -966
#define ER_LK_OBJECT_DL_TIMEOUT_CLASS_MSG           -967
#define ER_LK_OBJECT_DL_TIMEOUT_CLASSOF_MSG         -968
...

The following are some of the server error code names, error code numbers, and error messages.

Starting Broker¶

Enter the command below to start the broker.

$ cubrid broker start
@ cubrid broker start
++ cubrid broker start: success

The following message is returned if the broker is already running.

$ cubrid broker start
@ cubrid broker start
++ cubrid broker is running.

Stopping Broker¶

Enter the command below to stop the broker.

$ cubrid broker stop
@ cubrid broker stop
++ cubrid broker stop: success

The following message is returned if the broker has stopped.

$ cubrid broker stop
@ cubrid broker stop
++ cubrid broker is not running.

Restarting Broker¶

Enter the command below to restart the whole brokers.

$ cubrid broker restart

Checking Broker Status¶

The cubrid broker status utility allows you to check the broker status such as number of completed jobs and the number of standby jobs by providing various options.

cubrid broker status [options] [expr]

• expr: A part of the broker name or "SERVICE=ON|OFF"

Specifying expr performs that the status of specific brokers which include expr in their names is monitored; specifying no argument means that status of all brokers which are registered in the broker environment configuration file ( cubrid_broker.conf ) is monitored.

If "SERVICE=ON" is specified on expr, only the status of working brokers is displayed; if "SERVICE=OFF" is specified, only the status of stopped brokers is displayed.

The following [options] are available with the cubrid broker status utility. -b, -q, -c, -m, -S, -P and -f are options to define the information to print; -s, -l and -t are options to control printing. All of these are possible to use as combining each other.

-b¶

Displays the status information of a broker but does not display information on broker application server.

-q¶

Displays standby jobs in the job queue.

-f¶

Displays information of DB and host accessed by broker.

If it is used with the -b option, additional information on CAS is displayed. But SELECT, INSERT, UPDATE, DELETE, OTHERS items which shown on -b option are excluded.

If it is used with the -P option, STMT-POOL-RATIO is additionally printed. This item shows the ratio to use statements in the pool when you are using prepared statements.

-l SECOND¶

The -l option is only used with -f option together. It specifies accumulation period (unit: sec.) when displaying the number of application servers whose client status is Waiting or Busy. If it is omitted, the default value (1 second) is specified.

-t¶

Displays results in tty mode on the screen. The output can be redirected and used as a file.

-s SECOND¶

Regularly displays the status of broker based on specified period. It returns to a command prompt if q is entered.

If you do not specify options or arguments, the status of all brokers is displayed.

$ cubrid broker status
@ cubrid broker status
% query_editor

 4 28437     0     0 50140 IDLE
 5 28438     0     0 50144 IDLE

% broker1 OFF

• % query_editor: The broker name
• ID: Serial number of CAS within the broker
• PID: CAS process ID within the broker
• QPS: The number of queries processed per second
• LQS: The number of long-duration queries processed per second
• PSIZE: Size of CAS
• STATUS: The current status of CAS (BUSY, IDLE, CLIENT_WAIT, CLOSE_WAIT)
• % broker1 OFF: broker1's SERVICE parameter is set to OFF. So, broker1 is not started.

The following shows the detail status of broker for 5 seconds. The display will reset per 5 seconds as the new status information. To escape the display of the status, press <Q>.

$ cubrid broker status -b -s 5

• CANCELED: The number of queries have cancelled by user interruption since the broker starts (if it is used with the -l N option, it specifies the number of accumulations for N seconds).

Limiting Broker Access¶

To limit the client applications accessing the broker, set to ON for the ACCESS_ CONTROL parameter in the cubrid_broker.conf file, and enter a name of the file in which the users and the list of databases and IP addresses allowed to access the ACCESS_CONTROL_FILE parameter value are written. The default value of the ACCESS_CONTROL broker parameter is OFF. The ACCESS_CONTROL and ACCESS_CONTROL_FILE parameters must be written under [broker] which common parameters are specified.

The format of ACCESS_CONTROL_FILE is as follows:

[%<broker_name>]
<db_name>:<db_user>:<ip_list_file>
...

• <broker_name>: A broker name. It is the one of broker names specified in cubrid_broker.conf .
• <db_name>: A database name. If it is specified as *, all databases are allowed to access the broker server.
• <db_user>: A database user ID. If it is specified as *, all database user IDs are allowed to access the broker server.
• <ip_list_file>: Names of files in which the list of accessible IPs are stored. Several files such as ip_list_file1, ip_list_file2, ... can be specified by using a comma (,).

[%<broker_name>] and <db_name>:<db_user>:<ip_list_file> can be specified separately for each broker. A separated line can be specified for the same <db_name> and the same <db_user>. List of IPs can be written up to the maximum of 256 lines per <db_name>:<db_user> in a broker.

The format of the ip_list_file is as follows:

<ip_addr>
...

• <ip_addr>: An IP address that is allowed to access the server. If the last digit of the address is specified as *, all IP addresses in that rage are allowed to access the broker server.

If a value for ACCESS_CONTROL is set to ON and a value for ACCESS_CONTROL_FILE is not specified, the broker will only allow the access requests from the localhost.

If the analysis of ACCESS_CONTROL_FILE and ip_list_file fails when starting a broker, the broker will not be run.

# cubrid_broker.conf
[broker]
MASTER_SHM_ID           =30001
ADMIN_LOG_FILE          =log/broker/cubrid_broker.log
ACCESS_CONTROL   =ON
ACCESS_CONTROL_FILE     =/home1/cubrid/access_file.txt
[%QUERY_EDITOR]
SERVICE                 =ON
BROKER_PORT             =30000
......

The following example shows the content of ACCESS_CONTROL_FILE. The * symbol represents everything, and you can use it when you want to specify database names, database user IDs and IPs in the IP list file which are allowed to access the broker server.

[%QUERY_EDITOR]
dbname1:dbuser1:READIP.txt
dbname1:dbuser2:WRITEIP1.txt,WRITEIP2.txt
*:dba:READIP.txt
*:dba:WRITEIP1.txt
*:dba:WRITEIP2.txt

[%BROKER2]
dbname:dbuser:iplist2.txt

[%BROKER3]
dbname:dbuser:iplist2.txt

[%BROKER4]
dbname:dbuser:iplist2.txt

The brokers specified above are QUERY_EDITOR, BROKER2, BROKER3, and BROKER4.

The QUERY_EDITOR broker only allows the following application access requests.

• When a user logging into dbname1 with a dbuser1 account connects from IPs registered in READIP.txt
• When a user logging into dbname1 with a dbuser2 account connects from IPs registered in WRITEIP1.txt and WRITEIP2.txt
• When a user logging into every database with a DBA account connects from IPs registered in READIP.txt, WRITEIP1.txt, and WRITEIP2.txt

The following example shows how to specify the IPs allowed in ip_list_file.

192.168.1.25
192.168.*
10.*
*

The descriptions for the IPs specified in the example above are as follows:

• The first line setting allows an access from 192.168.1.25.
• The second line setting allows an access from all IPs starting with 192.168.
• The third line setting allows an access from all IPs starting with 10.
• The fourth line setting allows an access from all IPs.

For the broker which has already been running, you can modify the configuration file or check the currently applied status of configuration by using the following commands.

To configure databases, database user IDs and IPs allowed to access the broker and then apply the modified configuration to the server, use the following command.

cubrid broker acl reload [<BR_NAME>]

• <BR_NAME>: A broker name. If you specify this value, you can apply the changes only to specified brokers. If you omit it, you can apply the changes to all brokers.

To display the databases, database user IDs and IPs that are allowed to access the broker in running on the screen, use the following command.

cubrid broker acl status [<BR_NAME>]

• <BR_NAME>: A broker name. If you specify the value, you can display the specified broker configuration. If you omit it, you can display all broker configurations.

The below is an example of displaying results.

$ cubrid broker acl status
ACCESS_CONTROL=ON
ACCESS_CONTROL_FILE=access_file.txt

Broker Logs

If you try to access brokers through IP addresses that are not allowed, the following logs will be created.

• ACCESS_LOG

Managing a Specific Broker¶

Enter the code below to run broker1 only. Note that broker1 should have already been configured in the shared memory.

% cubrid broker on broker1

The following message is returned if broker1 has not been configured in the shared memory.

% cubrid broker on broker1
Cannot open shared memory

Enter the code below to stop broker1 only. Note that service pool of broker1 can also be removed.

% cubrid broker off broker1

The broker reset feature enables broker application servers (CAS) to disconnect the existing connection and reconnect when the servers are connected to unwanted databases due to failover, etc. in HA. For example, once Read Only broker is connected to active servers, it is not automatically connected to standby servers although standby servers are available. Connecting to standby servers is allowed only with the cubrid broker reset command.

Enter the code below to reset broker1.

% cubrid broker reset broker1

Dynamically Changing Broker Parameters¶

You can configure the parameters related to running the broker in the configuration file ( cubrid_broker.conf ). You can also modify some broker parameters temporarily while the broker is running by using the broker_changer utility. For details, see Broker Configuration.

The syntax for the broker_changer utility, which is used to change broker parameters while the broker is running, is as follows. Enter the name of the currently running broker for the broker_name . The parameters can be used only for dynamically modifiable parameters. The value must be specified based on the parameter to be modified. You can specify the broker CAS identifier ( cas_id ) to apply the changes to the specific broker CAS.

cas_id is an ID to be output by cubrid broker status command.

broker_changer broker_name [cas_id] parameters value

Enter the following to configure the SQL_LOG parameter to ON so that SQL logs can be written to the currently running broker. Such dynamic parameter change is effective only while the broker is running.

% broker_changer query_editor sql_log on
OK

Enter the following to change the ACCESS_MODE to Read Only and automatically reset the broker in HA environment.

% broker_changer broker_m access_mode ro
OK

Broker configuration information¶

cubrid broker info dumps the currently "working" broker parameters' configuration information(cubrid_broker.conf). broker parameters' information can be dynamically changed by broker_changer command; with cubrid broker info command, you can see the configuration information of the working broker.

% cubrid broker info

As a reference, to see the configuration information of the currently "working" system(cubrid.conf), use cubrid paramdump database_name command. By SET SYSTEM PARAMETERS syntax, the configuration information of the system parameters can be changed dynamically; with cubrid broker info command, you can see the configuration information of the system parameters.

Broker Logs¶

There are three types of logs that relate to starting the broker: access, error and SQL logs. Each log can be found in the log directory under the installation directory. You can change the directory where these logs are to be stored through LOG_DIR and ERROR_LOG_DIR parameters of the broker configuration file (cubrid_broker.conf).
