PK91001: MAXINACTIVEINTERVAL VALUE FOR HTTP SESSION MANAGEMENT NOT SETTING CORRECTLY ON GRID SERVERS HOSTING REPLICA SHARDS

PM01010; 6.1.0.5 Cumulative fix 4 for WebSphere eXtreme Scale
PM20441; 6.1.0.5 Cumulative fix 5 for WebSphere eXtreme Scale
PK93428: 6.1.0.5 Cumulative fix 3 for WebSphere eXtreme Scale
PK94683: 7.0 Cumulative fix 1 for WebSphere eXtreme Scale

APAR status

• Closed as program error.

Error description

• When setting maxInactiveInterval to a high value appropriate
  for use in HTTP session replication, the high value (such as
  1800) is able to be set correctly on the grid server with the
  primary shard, but on the replica shards it is fixed to 8
  no matter how it is set. This results in very quick timeouts
  if there is a problem with the primary server.
