Ending selected data group processes - assure_mimix - 10.0

This procedure can be used to end all or selected processes for a data group, or end a specific database apply process.

Data groups that are in an application group: The preferred method of ending data groups that are part of an application group is to use the End Application Group (ENDAG) command. The default behavior of the ENDDG command helps to enforce this best practice when necessary by not allowing the command to run when the data group is participating in a resource group with three or more nodes. (A data resource group provides the association between one or more data groups and an application group.) The ENDDG request will run when the data group is participating in a resource group with two nodes. You can also change the value specified for Override if in data rsc. group (DTACRG) parameter to allow a data group to be ended even if it is part of a resource group.

In application group environments with three or more nodes, it is particularly important to treat all members of an application group as one entity. For example, a configuration change that is made effective by starting and ending a single data group would not be propagated to the other data groups in the same resource group. However, the same change would be propagated to the other data groups if it is made effective by ending and starting the parent application group.

For additional information about the ENDDG command, refer to the following topics:

• What occurs when a data group is ended

• What replication processes are ended by the ENDDG command

To selectively end processes for a data group, do the following:

1. From the Work with Data Groups display, type a 10 (End DG) next to the data group that you want to end and press Enter.

2. The End Data Group (ENDDG) display appears. At the Process prompt, specify the value for the processes you want to end.   To see a list of values, press F4 (Prompt).

3. At the End process prompt, specify the value you want.

4. If the data group uses remote journaling, verify that the value of the End remote journaling prompt is what you want.

5. If you want to end only a selected apply session, press F10 (Additional parameters). Then specify the value for the session you want to end at the Apply session prompt.

6. To end the selected processes, press Enter.
