DB2 Net Search Extender Administration and User's Guide


Locking services

When you start DB2 Net Search Extender, the locking services automatically start. The locking services are needed to synchronize concurrent access to text indexes in Net Search Extender.

The locking services ensure that no two processes attempt to change a text index simultaneously, or that no process reads text index data while another process is making changes to the same text index data. Therefore, most processes request a lock on a text index before starting and release it again when processing has completed.

Note that the locking services for Net Search Extender text indexes must not be confused with DB2 locks that control access to DB2 tables.
