10 Managing the Control Center Agent

This section describes how to start and stop the Control Center Agent (CCA), and how to administer it using the cca_admin utility. The CCA manages deployment and execution of the mappings that are based on Code Templates. CCA is not part of the Control Center service hosted within the Oracle Database.

This section contains the following topics:

Starting and Stopping the Control Center Agent

This section describes how to start and stop the CCA.

When you invoke the ccastart for the first time, it prompts you to enter a password for the OC4J administrator account. The default user name for this account is oc4jadmin.

To start the CCA:

To stop the CCA:

For a representation of architectural structures of this installation, see Figure 1-5, "Control Center Agent Topology".

For procedures that modify installation defaults, see Chapter 7, "Configuring Repository Browser, Control Center Agent, and Other Components".

About the cca_admin Utility

The cca_admin utility changes Control Center Agent settings dynamically, without the requirement to shut down and subsequently restart the run-time environment. cca_admin commands retrieve the values of various environment attributes, set these to new values, and invoke the operations of JRTAdministratorMBean, introduced in section "JRTAdministratorMBean".

The typical cca_admin session includes the following steps:

Starting the cca_admin Utility

The cca_admin tool is delivered as a shell script on Linux or a batch file on Windows.

Before activating the JRTAdministratorMBean, your can use only the basic commands: help, connect, disconnect, and exit. The full range of commands is available after you connect to an MBean server and start using the JRTAdministratorMBean.

cca_admin Commands

This section provides a complete list of the cca_admin commands as follows:

cleanUpJobLogFilesForGivenTimeInterval

This command removes all log files that were modified during the specified time range, between startDate and endDate, and returns the total number of files removed. Both parameters are expressed in the format DD-MM-YYYY HH:MM:SS. If the specified startDate is null, no records are deleted. If endDate is null, all log files created after the startDate are purged.

Example 10-1 Using cleanUpJobLogFilesForGivenTimeInterval Command

cleanUpJobLogFilesForGivenTimeInterval 26-12-2008 13:38:56 12-01-2009 22:15:58

cleanUpNLeastRecentJobLogFiles

This command removes the specified number n, of least recent log files from the system, and returns the number of job log files that are actually removed.

Example 10-2 Using cleanUpNLeastRecentJobLogFiles command

cleanUpNLeastRecentJobLogFiles 10

connect

This command connects the user to MBean server.

The command is of the following form, where host is the computer on which the CCA is located, port is the port number for accessing the CCA, user is the user name for accessing the CCA, password is that user's password, connection_type is one of RMI, OPMN, RMIS, OPMN_RMIS, OPMN_CLUSTER, or OPMN_CLUSTER_RMIS, application_name is the name of the application deployed to OC4J, and instance is the OC4J process that contains the CCA application:

connect host port user password connection_type application_name instance

Example 10-3 Using connect Command

connect localhost 23791 oc4jadmin welcome rmi jrt host

disconnect

This command disconnects the user from the MBean server.

Example 10-4 Using disconnect Command

disconnect

exit

This command exits the cca_admin shell when it is running in the interactive mode. If the connection to the MBean server is not closed, it first disconnects and then exits cca_admin shell.

Example 10-5 Using exit Command

exit

getCacheJobStatusSize

This command returns a value for the number (integer) MBean attribute CacheJobStatusSize, which controls the maximum number of the job status logs that can be stored by the in-memory job log cache in CCA. The attribute's value is in the range of 1 and 10000, with the default value of 3000.

Example 10-6 Using getCacheJobStatusSize Command

getCacheJobStatusSize 3000

getCacheLogNo

This command returns the value of MBean attribute CacheLogNo, which controls the maximum number of job logs that can be stored by the in-memory job log cache in CCA. Obviously the bigger this number is the more memory CCA takes up. The attribute's value is in the range of 1 and 100, with the default value of 10.

Example 10-7 Using getCacheLogNo Command

getCacheLogNo

getKmPermissionsFile

This command returns the value of MBean attribute KmPermissionsFile, which is the file system path to the ct_permissions.properties file. If this parameter is set to true, the CCA checks ct_permissions.properties to determine what system commands may be executed. This path may be either absolute or relative. The relative value refers to the $OC4J_HOME/j2ee/home directory. The default value is config/ct_permissions.properties.

Example 10-8 Using getKmPermissionsFile Command
