APAR status
Closed as program error.
Error description
Historically, when multiple catalog primaries within a catalog cluster resulted from a brownout recovery, the eXtreme Scale domain or appliance collective was rendered corrupt. This scenario required manual intervention to make primary shards consistent again, or quorum was used to prevent change when quorum was violated.
Local fix
Problem summary
**************************************************************** * USERS AFFECTED: WebSphere eXtreme Scale and WebSphere * * DataPower XC10 Appliance users running * * without quorum enabled on their catalog * * servers. * **************************************************************** * PROBLEM DESCRIPTION: Catalog clusters do not recover * * from brownouts without the use of * * quorum. * **************************************************************** * RECOMMENDATION: * **************************************************************** With this fix, when the healing of brownouts lead to a partitioned catalog cluster with multiple primaries (as noted by the CWOBJ1506 log), 1 of the multiple primaries, and any containers also affected by the brownout, now restart. The domain recovers to a valid state automatically.
Problem conclusion
An interim fix is available for this APAR.
