Maintaining normal operations

Data sharing requires additions to your normal operating procedures. The following topics present sample operational scenarios that show how to perform routine adjustments and maintenance in a database-level data-sharing environment.

Recommendation: Use an External Time Reference (ETR) device and set it to use Universal Coordinated Time. You can set the local time for each data-sharing IMS system separately as necessary. See z/OS MVS Initialization and Tuning Reference for information on using an ETR.
