| LDEUQP | the size of the unique descriptor pool. | 0 | 16 777 215 | 5000 |
The unique (UQ) descriptor pool comprises elements that are the length of a unique descriptor value plus 11 bytes. The UQ descriptor pool should be large enough to hold all unique descriptors that are being changed by all transactions at any point in time.
In environments running in 31-bit adressing mode, the LDEUQP pool is allocated above the 16-megabyte line.
Assuming that the average length of unique descriptor values is about 9 bytes, this Adabas session can process a maximum of about 50 unique descriptors at one time.
