Selecting the version of a core group protocol

The high availability manager, by default, uses the original or base version of a protocol. However, you can upgrade to a newer protocol version, provided your system meets the product level requirements for that newer version.

Before you begin

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. The high availability manager, by default, uses the 6.0.0 version of the wire format protocol, and the 6.0.2.31 version of the HAM protocol.

Before you change the version of the core group protocol for a particular core group member, make sure that:

About this task

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 should verify that all of the members of a particular core group are configured to use the same version of a core group protocol.

To change the version of a core group protocol complete the following steps.

Procedure

  1. In the administrative console, click Servers > Core groups > Core group settings and select an existing core group.
  2. Under Additional Properties, click Custom Properties.
  3. Change the value of either the IBM_CS_WIRE_FORMAT_VERSION or IBM_CS_HAM_PROTOCOL_VERSION custom property.

    If you are updating the updating the lower level protocols, which are also referred to as the wire format protocols, change the value of the IBM_CS_WIRE_FORMAT_VERSION custom property.

    If you are updating the higher level protocols, which are also referred to as the high availability manager protocols, change the value of the IBM_CS_HAM_PROTOCOL_VERSION custom property.

    To update either of these custom properties, complete one of the following substeps:

    1. If the property that you want to update does not already exist, click New and then specify either IBM_CS_WIRE_FORMAT_VERSION or IBM_CS_HAM_PROTOCOL_VERSION in the Name field and the appropriate version ID in the Value field.
    2. If the property that you need to update already exists, click on the property name, and specify the appropriate version ID in the Value field.
  4. Click OK, and then click Review.
  5. Select Synchronize changes with nodes, and then click Save.

Results

Your changes take effect immediately after synchronization completes. The members of the core group pick up these changes dynamically.
