Issue/Introduction

What steps are necessary to increase the size of the Datacom/AD Database for the IMS Information Repository (IIR), if one of the Area datasets has become full?

Resolution

If one of the Datacom Area datasets has become full (e.g. abend SB37 occurs when trying to write additional data into this Area), the following
actions need to be performed to increase the Area dataset size (library names and dataset names need to be changed to your site specific names).
