EDM pool failures

The EDM pool stores cursor tables (CT), package tables (PT), and database descriptors (DBD).

Any pool full failures (FAILS DUE TO POOL FULL) indicate that the EDM pool is too small for the DB2 workload. The EDM pool should be big enough to store the cursor tables (CT), package tables (PT), and database descriptors (DBD). The ratios CT REQUESTS/CT NOT IN EDM, PT REQUESTS/CT NOT IN EDM, and DBD REQUESTS/CT NOT IN EDM show the EDM pool utilization. Generally, ratios of about 80% are adequate in most cases. If these values are significantly lower, reduce the size of the EDM pool and allocate the saved storage to the buffer pool, where the performance benefits are greater.
