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.
|
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:
|
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:
|
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:
|
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:
|
Setup unit |
Method of setup |
Location of setup |
|---|---|---|
|
J2EE server |
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.
