Information on Notes ID tables

"Unable to extend an ID table - insufficient memory."

This will typically happen in database with the following characteristics:

• Large number (100,000 +) of documents and/or deletion stubs.
• Documents are being continually added to and deleted from the database, typically several thousand per day.

• Restore from a backup made prior to running Fixup or Compact, then pull a new replica.

• Consider reducing the purge interval, thereby reducing the number of deletion stubs.

The Fixup and Compact tasks build an ID table that contains pointers to an ID for every document in a database, including deletion stubs. The ID table is limited in size. The ID pointers are stored in a compressed format, which is most efficient in a newly-built database. As documents are added and deleted over time the ID table can become very fragmented and eventually will overflow.
