IT31914: SBSPACE INCREMENTAL BACKUP POTENTIALLY BLOCKING INSTANCE FOR LONG TIME

APAR status

• Closed as program error.

Error description

• Incremental (level 1 / 2) backups of sbspaces containing (or
  having contained) very large numbers of large objects can still
  block an instance (Blocked:ARCHIVE) for extended periods of
  time.
  Reason is that reading ahead of meta data pages might only be
  working for initial set of pages for each chunk in the sbspace,
  depending on (base page size) bufferpool size.
