• Define IMS subsystems, Internal Resource Lock Manager (IRLM), and coupling facilities to use IMS data sharing
• Design recovery procedures for failures in the data sharing environment
• Understand application design considerations with IMS data sharing
• Monitor the performance of a data sharing environment
• Explain IRLM and coupling facility roles in support of IMS data sharing.

This is an advanced course for IMS system programmers and database administrators, who implement and manage IMS systems using data sharing.

You should complete:

• IMS Database Recovery Control (DBRC) and Data Sharing (CM201) or
• IMS Database Recovery Control (DBRC) and Data Sharing - Web (CMW20)
• or have equivalent work experience

You should have working knowledge of IMS databases and the use of DBRC.
