How you actually install the global resource serialization complex depends — like every other decision related to global resource serialization — on the needs of your installation. Here are some installation considerations:

• Identify the resources that you must include in the RNLs to get benefits from the complex as quickly as possible.
• Define the long-term resource processing goals for your installation.
• Evaluate the data set naming conventions at your installation and begin making any changes required to make better use of global resource serialization.
• Evaluate the possibility of modifying existing applications to use global resource serialization more effectively.
• Determine how global resource serialization will affect the design of future applications.
• Prepare the initial educational and procedural material for the system operators.
• Leave the RESERVE conversion RNL empty if you plan to continue using RESERVE/DEQ for data set serialization until the complex matches the sysplex.
• Complete any shared DASD changes required to ensure that the complex does not share DASD volumes with systems outside the complex.
