Problem IT03677
|
Status: Closed |
When PCKCACHESZ parameter is set to a value > 524288, the package cache will be cleaned too aggressively. |
| product: |
DB2 FOR LUW / DB2FORLUW / A10 - DB2 |
| Problem description: |
When we set package cache size to a value larger than 524288
pages, the package cache will be cleaned too aggressively, with
almost no entries retained.
When checking the output from db2pd -dynamic, we will see
results similar to the following. We will see a large "Total
Heap Size", but small "Current Memory Used" and only a small
"Number of Statements" in the cache.
db2pd -dynamic:
Current Memory Used 947264
Total Heap Size 2383872000
Cache Overflow Flag 0
Number of References 149
Number of Statement Inserts 149
Number of Statement Deletes 121
Number of Variation Inserts 149
Number of Statements 28
This APAR should resolve the above observed issue. |
