Release Notes (FixPak 3)

3Alternate FixPaks on UNIX-based systems

3Prior to DB2 Universal Database Version 8, FixPaks only functioned as 3updates to installed DB2 Universal Database packages or filesets in one single 3fixed location. Essentially, this meant that the installation of 3FixPaks would replace existing files with the updated ones provided within the 3FixPaks, and multiple DB2 FixPak levels on a single system was not a 3possibility. DB2 Universal Database Version 8.1 Enterprise 3Server Edition (ESE) with different FixPak levels can now exist in the same 3system. This has been supported in production since Version 38.1.2. This is accomplished by the fact that there are 3now two types of FixPaks: 3

3Regular Fixpaks

3

• 3available not only for ESE, but for all supported DB2 V8.1 products 3for the related platforms
• 3can be installed directly on top of the existing installation either in 3/usr/opt/db2_08_01 on AIX^(R) or 3/opt/IBM/db2/V8.1 on other platforms 3

3Alternate FixPaks

3

• 3can be installed as a completely new copy of DB2 Universal Database ESE
• 3installed in a predefined location other than the location used for a 3regular DB2 Universal Database installation 3

3Notes:

1. 3You are not required to perform a multiple FixPak installation 3if you do not feel it is necessary for your environment.

2. 3Starting with DB2 Universal Database v8.1.2 for UNIX^(R) 3and Linux, Enterprise Service Edition (ESE) Fixpaks are supported in 3production when installed as Multiple Fixpaks. 3

3To update a multiple FixPak instance to a different FixPak level, perform 3one of the following options: 3

• 3Install the appropriate Regular FixPak on the GA (General Availability) 3installation, and update the instance by running db2iupdt from the existing GA 3path
• 3Install the appropriate Alternate FixPak to its own unique path, and 3update the instance by running db2iupdt from this path 3
