Managing instances, members, and cluster facilities in DB2 pureScale

In this recipe, we will cover different operations that can be executed on instances, members, and cluster facilities. Our system configuration is composed by two members and two caching facilities. They will be presented with parameters related to pureScale and commands related to stopping, starting, and going into maintenance state.

Getting ready

In our recipes, we will use a DB2 pureScale setup, with two members and two CFs, running on IBM AIX operating system.

Being a clustered environment, the instance itself has to know about the participating member and cluster facilities, and also about the shared device path. The members are used for administrative operations; there could be up to 128 members. The CF can be considered as an instance and database extension, using two sets of parameters that control memory, locking, and diagnostic values on every member.
