Binding the CA CSM Application Server to a TCP/IP Stack in a Multi-TCP/IP Stack Environment

When your LPAR with CA CSM has multiple TCP/IP stacks, establish a TCP/IP stack affinity to a desired stack. Establishing a stack affinity binds all socket communications to that stack.

To establish a stack affinity, select one of the following methods:

• Add a DD statement SYSTCPD DD to the CA CSM startup JCL (RunTimeMVSHLQPrefix.JCL(MSMTCSRV)) pointing to a specific TCPIP.DATA data set. For example:

      //SYSTCPD DD DSN=TCPIP.SEZAINST(TCPDATA),DISP=SHR
  

• Add the environment variable _BPXK_SETIBMOPT_TRANSPORT to the RunTimeMVSHLQPrefix.SAMPLIB(MSMLIB) member that is associated to the STDENV DD of the CA CSM application server. For example:

      export _BPXK_SETIBMOPT_TRANSPORT=stackname
  

• Add an extra step, AFFINITY, in the CA CSM startup JCL (RunTimeMVSHLQPrefix.JCL(MSMTCSRV)) before the MSMSRV step:

      //AFFINITY EXEC PGM=BPXTCAFF,PARM=stackname
