C.6 Tuning parameters for optimizing the operation of CTM (methods other than the recommended procedures)

This subsection describes the locations to set up the tuning parameters used for optimizing the operation of CTM.

Organization of this subsection

(1) Tuning parameters for setting up the monitoring interval of the operating state of CTM domain managers and CTM daemons

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.

Location of setup

CTM domain managers existing in the same network segment

Send interval

Argument -CTMAliveCheckCount of the ctmdmstart command

The parameter for tuning the monitoring interval of the operating state of the CTM daemons is as follows:

Setup item

Method of setup

Location of setup

Timeout during transfer between CTM daemons

Execute command

Argument -CTMDCSendTimeOut of the ctmstart command

(2) Tuning parameters for setting up the monitoring interval of the load status

The tuning parameter for the monitoring interval of the load status is as follows:

Table C‒16: 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

(3) Tuning parameters for setting up the timeout lock for CTM daemon

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‒17: 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

(4) Tuning parameters for setting up a priority order for the requests distributed by CTM

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:

Edit file

ejbserver.client.ctm.RequestPriority key of usrconf.properties

The tuning parameters for each EJB client application are the same as specified in the recommended procedures.
