Updating DB2 copies (Linux and UNIX)

You can update an existing DB2® copy and all instances running on that copy. You can also choose to install a new DB2 copy and selectively update instances to run on this new copy after installation.

To update your DB2 copies:

1. Log on with root user authority.
2. Stop all DB2 processes.
3. Update each DB2 copy using one of the following choices:
   • To update an existing DB2 copy and update all the instances running on this DB2 copy, issue the installFixPack command. You cannot install additional functionality with this command.
   • To install a new DB2 copy and selectively update the instances running on an existing DB2 copy to the new copy after installation, issue the db2setup command and select Install New in the Install a Product panel. To install a new copy, you can also perform a response file installation specifying a new location as installation path. Any of these options allow you to also install additional functionality.
   • To add functionality to an existing DB2 copy, select Work with Existing in the Install a Product panel. Then select the DB2 copy that you want to update with the Add new function action. This action is only available when the DB2 copy is at the same release level as the install image. To add functionality, you can also perform a response file installation or issue the db2_install command.
   Important: The command db2_install is deprecated and might be removed in a future release. Use the db2setup command with a response file instead.
4. If you installed a new DB2 copy, use the db2iupdt command to update any instances that are running in a different DB2 copy of the same release that you want them to run under the new copy. The following table shows several examples of updating instances:

   Instance	DB2 copy	Example to update to another copy
   db2inst1	/opt/IBM/db2/V9.1/	cd /opt/IBM/db2/V9.1_FP3/instance ./db2iupdt db2inst1
   db2inst2	/opt/IBM/db2/V9.5FP2/	cd /home/db2/myV9.5_FP1/instance ./db2iupdt -D db2inst2a
   db2inst3	/opt/IBM/db2/V9.7/	cd /home/db2/myV9.7/instance ./db2iupdt -k db2inst3b

   Note:

   1. Use the -D parameter to update an instance from a later release level copy to a earlier release level copy.
   2. Use the -k parameter to keep the current instance type during the update to a DB2 copy that has a higher level of instance type. If you updated from WSE to ESE, when you update the instance without this parameter the instance type wse is converted to ese.
