Non-disruptive maintenance for Reorg Online products
In a continuing effort to maximize IMS database availability, BMC offers non-disruptive maintenance (NDM) for Reorg Online products.
NDM provides a means to install maintenance or an emergency fix without an IMS system outage.
NDM is available for the following Reorg Online products:
BMC AMI Online Reorg for IMS
MAXM Reorg/EP for IMS with Online/Defrag Feature
MAXM Reorg for IMS with Online/Defrag Feature
NDM is modeled after the IMS Online Change Utility. The following figure shows sample JCL for the IMS Online Change Utility.

Because NDM is modeled after the IMS Online Change Utility, the library requirements are similar. The following figure compares the IMS Online Change Utility and NDM data sets.
