CMRDTN view
BMC AMI Ops Monitor for CICS provides an optional Dynamic Tuning function that operates within a target IBM CICS region. You can use the Dynamic Tuning to monitor and dynamically alter the Db2 Connection TCBLIMIT and THREADLIMIT attributes.
By default, the function is disabled. For more information about how to turn on the Dynamic Tuning function, see Implementing-Dynamic-Tuning-of-IBM-Db2-Connections.
Use the CMRDTN views and dialogs to specify a group of targets that you want to control. For each Target Group parameter, define the range of values you want to be used when dynamically altering the Db2 Connection TCBLIMIT and THREADLIMIT attribute values.
BMC AMI OpsM for CICS saves these definitions in BBPARM members CMRDTNnn in the first concatenation of the BBIPARM DD in the BBI-SS PAS. The default member name is CMRDTN00 unless you are using the BBCFG facility. For more information, see BBIBBCFG facility.
If Dynamic Tuning is enabled and the current CICS target name is not defined in CMRDTNnn (either explicitly or by wildcard) the target will not have Dynamic Tuning activated.
Dynamic Tuning for the Db2 Connection operates in conjunction with the following:
- Alarm definition CICSD2CNSETATR, which monitors resource consumption values in the CDB2CONT view. This alarm is triggered when the CDB2CONT view processing determines a new attribute value is desired.
- BMC AMI Ops Automation Rule definition CMRD2CST, which is triggered when the CICSDB2NSETATR alarm issues messages indicating a new attribute value is desired.
- BMC AMI Ops Automation REXX EXEC CMRD2CNA, which invokes SET commands to alter the attribute values.
