This subsection describes the locations to set up the tuning parameters used for optimizing the operation of CTM.
The following table describes the parameters for tuning the monitoring interval of the operating state of the CTM domain manager:
The monitoring interval is the value after multiplying the send interval with the coefficient.
Table C-19 Parameters for tuning the monitoring interval of the operating state of CTM domain manager (methods other than the recommended procedures)
Target | Setup item | Method of setup | Location of setup |
---|---|---|---|
CTM domain managers existing in the same network segment | Send interval | Execute command | Argument -CTMSendInterval of the ctmdmstart command |
Coefficient | Execute command | Argument -CTMAliveCheckCount of the ctmdmstart command | |
CTM domain managers existing in a different network segment | Send interval | Execute command | Argument -CTMSendHostInterval of the ctmdmstart command |
Coefficient | Execute command | Argument -CTMAliveCheckCount of the ctmdmstart command |
The parameter for tuning the monitoring interval of the operating state of the CTM daemons is as follows:
Table C-20 Parameter for tuning the monitoring interval of the operating state of CTM daemons (methods other than the recommended procedures)
Setup item | Method of setup | Location of setup |
---|---|---|
Timeout during transfer between CTM daemons | Execute command | Argument -CTMDCSendTimeOut of the ctmstart command |
The tuning parameter for the monitoring interval of the load status is as follows:
Table C-21 Tuning parameter for the monitoring interval of the load information (methods other than the recommended procedures)
Setup item | Method of setup | Location of setup |
---|---|---|
Timeout during transfer between CTM daemons | Execute command | Argument -CTMLoadCheckInterval of the ctmstart command |
The timeout lock is executed by setting up the timeout occurrence frequency and the monitoring interval.
The tuning parameters for the timeout lock of the CTM daemon are as follows:
Table C-22 Tuning parameters for the timeout lock of a CTM daemon (methods other than the recommended procedures)
Setup item | Method of setup | Location of setup |
---|---|---|
Timeout occurrence frequency | Execute command | Argument -CTMWatchRequest (first optional argument) of the ctmstart command |
Monitoring interval | Execute command | Argument -CTMWatchRequest (second optional argument) of the ctmstart command |
The setting of the priority order of requests distributed by CTM is different for an EJB client application and for a J2EE server. Moreover, for a J2EE server, the location of setup differs depending on how the system is built. The tuning parameters for setting up the priority order of requests distributed with CTM, are as follows:
Table C-23 Tuning parameters for setting up the priority order of requests distributed by
Setup unit | Method of setup | Location of setup |
---|---|---|
J2EE server | Edit file | ejbserver.client.ctm.RequestPriority key of usrconf.properties |
CTM (methods other than the recommended procedures)
The tuning parameters for each EJB client application are the same as specified in the recommended procedures.
