Building the SLB Dynamic API Environment

IMS Database Recovery Facility has the capability to use IMS Recovery Expert System Level Backups (SLB) as recovery assets.

When IMS Recovery Expert creates an SLB, it can keep track of all DBDS that are backed up in the SLB. The SLB contains the equivalent of fast-replication image copies for each DBDS in the SLB.

A dynamic application programing interface (API) is provided that allows IMS Database Recovery Facility jobs to utilize these SLBs for image copies when those SLBs can meet the recovery criteria better than an image copy recorded in the RECON data sets. By using IMS Recovery Expert SLBs as image copies, you can reduce the need for creating image copies.

When you drive recovery from the IMS Database Recovery Facility and use IMS Recovery Expert to create system level backups, you must install the dynamic API in order for SLBs to be used as valid recovery assets. If you drive recovery form the IMS Recovery Expert (which has the ability to drive the IMS Database Recovery Facility) you do not need to install the API.
