APPC Hot Backup Application Slow to Recover When Primary Fails (275722)

SYMPTOMS

APPC/5250 applications connecting to SNA Server computers that are configured for APPC Load Balancing and Hot Backup may be slow to reestablish a session to a backup server once the primary node/connection becomes unavailable.

CAUSE

If a client has an APPC/5250 session through an existing SNA Server which becomes unavailable, the client still attempts (two more times) to reestablish itself to the same SNA Server before moving onto the second server.
