Installing a fix pack (Linux® and UNIX)
You can use offline fix pack updates on Db2® instances to update an existing Db2 database product to a new fix pack level or to install a new Db2 database product at a particular fix pack level.
For Db2 instances in Db2 environments other than Db2 pureScale® environments, you can update the version of a Db2 instance to a higher code level by performing an offline fix pack update.
For Db2 pureScale instances, you can update them to a higher code level by using offline fix pack updates or online fix pack updates. Starting with Db2 version 10.5, you can use online fix pack updates to keep your databases available while the fix pack update is in progress.
