To update the configuration for root instances on Linux or UNIX operating systems, use the db2iupdt command. To update non-root instances, run the db2nrupdt command.
About this task
Running the
db2iupdt command updates
the specified instance by performing the following:
- Replaces the files in the sqllib subdirectory
under the home directory of the instance owner.
- If the node type has changed, then a new database manager configuration
file is created. This is done by merging relevant values from the
existing database manager configuration file with the default database
manager configuration file for the new node type. If a new database
manager configuration file is created, the old file is backed up to
the backup subdirectory of the sqllib subdirectory under the home directory of the instance owner.
The db2iupdt command
is located in the DB2DIR/instance directory, where DB2DIR is the location where
the current version of the DB2® database product is installed.
Restrictions
This task applies to root instances only.
Procedure
To update an instance from the command line, enter: db2iupdt InstName
The InstName is the login name of the instance
