Starting (and resetting) CTG monitoring

Before the IBM CICS Transaction Gateway can be monitored, it must be installed and configured to work with BMC AMI Ops Monitor for CICS.

For information about getting the gateway to work with BMC AMI OpsM for CICS, see Customizing-after-installation.

After CTG monitoring is active, you can reset the current monitoring parameters with the RESET command with the Parm option from an IBM MVS console, or with the LOG display.

To reset the parameters from an MVS console, use the MODIFY command:

F pasname,RESET PARM,CMRCTG

where pasname is the BBI-SS PAS stcname.

To reset the parameters from the LOG display:

.RESET PARM CMRCTG

When the command is issued, the current CTG parameters are refreshed with the values from the parameter file, CMRBEXnn. With this command you can

  • Turn CTG monitoring support on and off, based on the setting of the CTGMON parameter
  • Increase the maximum number of gateways that can be monitored by a PAS, based on the setting of the MAXGATE parameter (this value cannot be decreased while the PAS is active).
  • Increase the home data space size, based on the setting of the DSPLIM parameter (this value cannot be decreased while the PAS is active)
  • Add or remove gateways from those monitored by the PAS, based on the setting of the CTGNAME parameter

Do not use the RESET command to change the PORT and DSPSIZE parameters for an existing CTGNAME. To change these parameter, turn CTGMON off and make the changes for an existing CTGNAME, then turn CTGMON back on.

For more information about the RESET command, see BBI control commands.

Console command for the gateway request exit

For CTG version 7.2 and later, if CTG monitoring is already active, you can control the gateway request exit by using the following CTG console interface command:

/F ctgname,APPL=RMEXIT,COMMAND=CMR command

where:

ctgname is the name of the CTG daemon JOB/STC to process the request

CMR command is one of the following commands:

CMR QUIESCE requests the exit to stop processing transaction data. This command does not terminate the BMC AMI OpsM for CICS gateway request exit; the exit simply idles until a CMR RESUME command is received.

CMR RESUME requests the exit to resume processing transaction data.

Information
Example

To stop collecting task performance data with the MVCICS gateway request exit, use the following command:

/F BCVDWBTG,APPL=RMEXIT,COMMAND=CMR QUIESCE

To resume collecting task performance data with the MVCICS gateway request exit, use the following command:

/F BCVDWBTG,APPL=RMEXIT,COMMAND=CMR RESUME
