Issue/Introduction

A RC/Compare for Db2 for z/OS (RCC) Batch Automap Compare runs for a long time when comparing the source DDLIN file to a target DDLINTRG file.

Resolution

If the two DDL files, DDLIN and DDLINTRG, contain a large number of objects, this could either result in extremely long run times, or potentially fail with storage problems.

Reduce the number of source and target objects in the DDLIN and DDLINTRG files.

Would not recommend exceeding 200000 lines in the DDL files, which equates to approximately 80000 objects, dependent on the object type.
