DB2 Net Search Extender Administration and User's Guide

Disabling a database

Summary

When
When you no longer intend to make text searches in this database.

Command
DISABLE DATABASE FOR TEXT

Authorization
DBADM on the database

When DB2 Net Search Extender prepares the database for use, certain administrative changes are made. This section describes functions that help you to reverse this process.

To disable the connected database, use the following command:

db2text DISABLE DATABASE FOR TEXT

When you disable a database, you also delete the following objects:

To disable the database and remove all the text indexes, use the following command:

db2text DISABLE DATABASE for text force
Note

Disabling a database will fail if there are any text indexes defined in the database. It is recommended to remove these indexes one by one and then check if any problems occur. If you use the disable database for text force command, it only guarantees that Net Search Extender catalog tables in the database are removed.

However, if some of the indexes can not be completely dropped, there may still be resources that need to be manually cleaned up. These include:

  • Files in the index, work and cache directory
  • Scheduler entries in ctedem.dat
  • Where an index was created using the replication capture option, the IBMSNAP_SIGNAL, IBMSNAP_PRUNE_SET, and IBMSNAP_PRUNCNTL entries in the tables of the remote database must be manually deleted. These entries can be easily identified using APPLY_QUAL="NSE"||<instance name> and TARGET_SERVER= <database name> command.

    In the following example, the instance is DB2 and the database is SAMPLE.

    DELETE FROM <ccSchema>.IBMSNAP_SIGNAL
    WHERE SIGNAL_INPUT_IN IN
            (SELECT MAP_ID FROM <ccSchema>.IBMSNAP_PRUNCNTL
            WHERE APPLY_QUAL= 'NSEDB2' AND TARGET_SERVER= 'SAMPLE');
     
    DELETE FROM <ccSchema>.IBMSNAP_PRUNCNTL
    WHERE APPLY_QUAL= 'NSEDB2' AND TARGET_SERVER= 'SAMPLE';
     
    DELETE FROM <ccschema>.IBMSNAP_PRUNE_SET
    WHERE APPLY_QUAL= 'NSEDB2' AND TARGET_SERVER= 'SAMPLE';
