Appendix 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
(2) Tuning parameters for setting up the monitoring interval of the load status
(3) Tuning parameters for setting up the timeout lock for CTM daemon
(4) Tuning parameters for setting up a priority order for the requests distributed by CTM

(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.

Table C-19 Parameters for tuning the monitoring interval of the operating state of CTM domain manager (methods other than the recommended procedures)

TargetSetup itemMethod of setupLocation of setup
CTM domain managers existing in the same network segmentSend intervalExecute commandArgument -CTMSendInterval of the ctmdmstart command
CoefficientExecute commandArgument -CTMAliveCheckCount of the ctmdmstart command
CTM domain managers existing in a different network segmentSend intervalExecute commandArgument -CTMSendHostInterval of the ctmdmstart command
CoefficientExecute commandArgument -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 itemMethod of setupLocation of setup
Timeout during transfer between CTM daemonsExecute commandArgument -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-21 Tuning parameter for the monitoring interval of the load information (methods other than the recommended procedures)

Setup itemMethod of setupLocation of setup
Timeout during transfer between CTM daemonsExecute commandArgument -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-22 Tuning parameters for the timeout lock of a CTM daemon (methods other than the recommended procedures)

Setup itemMethod of setupLocation of setup
Timeout occurrence frequencyExecute commandArgument -CTMWatchRequest (first optional argument) of the ctmstart command
Monitoring intervalExecute commandArgument -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:

CTM (methods other than the recommended procedures)

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