PK74800: FAILURE TO CREATE A CLUSTER WITH TWO CLUSTER MEMBERS THAT HAVE THE SAME NAME BUT DIFFERENT SHORT NAMES IN TWO DIFFERENT NODES

Fixes are available

APAR status

Closed as program error.

Error description

The customer attempted to create a cluster with two cluster
members that have the same name (server_specific_name), but
different short names in two different nodes, but the server
failed on start with BBOM0057W message and DC3 abend.  The
server_specific_uuid in was.env of the cluster members has more
than the 40-chars limit (the failed server_specific_uuid has 80
chars - to be exact).
Here's the symptom:
IEF403I DVSR99CS - STARTED - TIME=14.53.33
+BBOM0057W DEFAULT VALUE OF ENVIRONMENT VARIABLE
server_specific_uuid
USED. LENGTH MUST NOT EXCEED 40 CHARACTERS.

Problem summary

****************************************************************
* USERS AFFECTED:  All users of WebSphere Application Server   *
*                  V6.1.0 for z/OS                             *
****************************************************************
* PROBLEM DESCRIPTION: Failure to start a cluster member       *
*                      when two cluster members have the       *
*                      same name but are in different nodes.   *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
When two cluster members have the same name on different
nodes, the cluster members cannot be started.
During cluster creation, the configuration save operation
generates the server_specific_uuid property incorrectly by
concatenating the individual cluster member uuid's together
since they have the same name.  This causes the startup
failure since the server_specific_uuid is limited to 40
characters.
The following message is seen in the cluster member's log at
startup:
BBOM0057W DEFAULT VALUE OF ENVIRONMENT VARIABLE
server_specific_uuid USED.   LENGTH MUST NOT EXCEED 40
CHARACTERS.

Problem conclusion

The code has been fixed to properly generate the
server_specific_uuid when more than one cluster member has the
same name.   This problem exists only on z/OS.

APAR PK74800 is currently targeted for inclusion in Service
Level (Fix Pack) 6.1.0.23 of WebSphere Application Server V6.1
for z/OS.

Temporary fix
