Setting up dynamic targets

When a Db2 target comes up, BMC AMI Ops Monitor for Db2 automatically manages the target without configuring it in the BBIJNT00 BBPARM member. By discovering targets dynamically, less manual processing is required and you can easily move a target from one LPAR to another.

By default, dynamic targeting is activated. For more information, see Activating dynamic targeting.

How BMC AMI OpsM for Db2 processes static and dynamic targets

When BMC AMI OpsM for Db2 starts, it first processes static BBIJNT00 entries. The PAS then searches for targets that are not being monitored by any PAS and dynamically adds them to BBIJNT00 (up to 15 targets per PAS including static entries). You can see all discovered targets on the THDACTV view.

Important

  • If a static target has already been dynamically discovered by another PAS (sharing the same CAS), it is monitored by the PAS that first discovered it.
  • If a static target (that was previously inactive) comes up, message DZ3325I notifies you that it is being monitored.
  • If a previously inactive target that is not defined in BBIJNT00 comes up, message DZ3327I notifies you that it is being monitored.

Differences between static and dynamic targets

For static targets:

  • You must configure BBIJNT00 by entering the SSID of each Db2 target that you want the PAS to manage.
  • If you change the location (LPAR) of a target, you must update BBIJNT00.
  • If you add new Db2 targets, you must manually update BBIJNT00 before BMC AMI OpsM for Db2 can start monitoring the targets.

For dynamic targets:

  • Targets are added to BBIJNT00 as they are discovered, and BMC AMI OpsM for Db2 automatically starts monitoring the targets.
  • Dynamic targets support alias names. For more information, see Specifying an alias name for dynamic targets.

Important

BMC AMI OpsM for Db2 can dynamically discover targets that are running on the BMC AMI OpsM for Db2 BBI-SS PAS only. BMC AMI OpsM for Db2 Data Collector targets must be defined in the DOMPLEX options.


Activating dynamic targeting

After installation, update the following BBIPARM members to activate dynamic targeting:

Member name

Parameter

DMRBEX00

DYNTGTDB2=YES (BPD5197 applied)

DMRBEX00

DYNTGTDB2=NO (BPD5197 not applied)

BBISSP00

DYNTGT=YES

Important

  • The default value for the DYNTGTDB2 parameter is YES. (BPD5197 applied)
  • The default value for the DYNTGTDB2 parameter is NO. (BPD5197 not applied)
  • To activate dynamic targeting, you must specify YES for DYNTGT parameter.

Specifying an alias name for dynamic targets 

You can use the DYNALIAS parameter in DMRBEX00 to specify an alias name for dynamic targets. If specified, the alias name is appended to the Db2 target name. 

By default, DYNALIAS=NONE. You can specify a hard coded name (up to four characters long), or use system symbols such as &SYSNAME.

Tip

You can see a list of defined system symbols by typing /d symbols on the SDSF menu. For more information about using system symbols, see BBPARM-data-set-members andSystem symbols.

Example

The following example shows the PLEXOVER view when DYNALIAS=&SYSNAME is specified. In this example, there are 13 dynamic Db2 target names that include the PAS alias (ESAJ) and 2 static entries (VXGDEHP and VXGDLYJ).
