There are two major categories or groups of high availability manager protocols. Both of these protocol groups can be independently configured to use newer versions of the protocols.
Before you change the version of a core group protocol for a particular core group member, make sure that:
The high availability manager can use any supported core group protocol versions. However, to ensure that proper communication continues between all core group members, you must make sure that all member of a particular core group use the same version of a core group protocol.
To change the version of a core group protocol complete the following steps.
You can check your SystemOut.log file or, for z/OS, either SYSOUT or SYSPRINT, for DCSV0005I and HMGR0226I messages.
DCSV0005I: DCS Stack DefaultCoreGroup at Member DIAMONDCell01\DIAMONDCellManager01\dmgr: Started. Stack version information: DCSBV_WAS6_1_20060409. Stack protocol information: 61002.
The Stack protocol information value at the end of this message indicates the protocol version that is being used. For example, a value of 51001 means the 6.0.0 version is being used. A value of 61002 means the 6.1.0 version is being used.
HMGR0226I: The core stack configuration parameter IBM_CS_HAM_PROTOCOL_VERSION has been set to 6.0.2.31.
This message indicates that the high availability manager protocol version 6.0.2.31 is being used.
