This task provides steps for removing a DB2® database product from your Linux or UNIX operating system.
About this task
This task is not required to install a new version of
a DB2 database product. Each
version of a DB2 database product
on Linux or UNIX has
a different installation path and can therefore coexist on the same
computer.
Note: This task applies to DB2 database
products that were installed with root user authority. A separate
topic explains how to uninstall DB2 database
products that were installed as a non-root user.
Procedure
To remove your DB2 database
product:
- Optional: Drop all databases. You can drop databases using the DROP
DATABASE command. Database files remain intact on your file
systems when you drop an instance without dropping databases first.
- Stop the DB2 Administration
Server.
- Remove the DB2 Administration
Server, or run the dasupdt command to update the DB2 Administration Server to another
installation path.
- Stop all DB2 instances.
- Remove the DB2 instances,
or run the db2iupdt command to update the instances
to another installation path.
- Remove the DB2 database
products.
