3-4 Administrative Products for DB2 Installation Guide
Upgrading Shared Components
Upgrading Shared Components
All Administrative Products share the following components:
• JCL Generation, which controls the JCL generation process
• Execution Monitor, which controls worklist processing by reading and
performing worklist commands
When you unload Administrative Products from the distribution tape, these
components are also unloaded. The Install System copies these components
to an APF-authorized load library that is shared by any of the Administrative
Products.
When you are completing a Maintenance installation, you must bind each
product to the new level of the components, if the products are using the
same APF-authorized load library.
Note: To share the same APF-authorized load library, the products must be
at the same version and release levels.
For example, you have ALTER version 5.4.04 and DASD MANAGER PLUS
version 5.4.04 installed, and you are using the same APF-authorized load
library. If you want to upgrade to version 6.1.01 for ALTER only, you need to
bind DASD MANAGER PLUS to the new JCL Generation and Execution
Monitor components.
Note: If you do not properly bind all Administrative Products that share the
common components, any attempts to generate JCL or to run
worklists can cause SQLCODES -805 and -818. The product that has
not been bound or upgraded will not run.
You do not have to bind a product separately to the shared components if the
following conditions exist:
• You are using the same APF-authorized load library and you are
upgrading all of your products, which are at the same version and release
level, at the same time. The binds will be done during the upgrade.
• You are using separate APF-authorized load libraries for your products.
