Before you can create a text index and search your documents, you have to start the DB2 Net Search Extender Instance Services.
To start the Instance Services, log on to the DB2 instance owner user ID (UNIX systems only) and enter the following command:
db2text start
To stop the Instance Services, enter the following command:
db2text stop
Note that there must be one Net Search Extender Instance Service per DB2 instance. The locking service maintains the locks for multiple databases.
