Status: Closed |
ASYNCHRONOUS BACKGROUND TASK PROCESSOR (ABP) ENCOUNTERED UNRECOVERABLE ERROR |
| product: |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 |
| Problem description: |
If ABP task processor encounters a resource capaticy error (such
as buffer pool full), it will end in error and users will see
the following message in db2diag.log:

MESSAGE : ADM13500E An agent executing an asynchronous
background task processor encountered an unrecoverable error.
The task processor has been suspended and diagnostic
information was written to the db2diag.log. Contact IBM
Support for assistance. The task processor context is
"0x000000023242AB20". The task processor description is
"Table: <schema>.<table>, Index: <schema>.<index>". |
| Problem Summary: |
The ABP task processor was implemented to end in error if it
encounters a resource capacity error. By nature ABP is a
low-priority background running process (tasked with cleaning up
pseudo-deleted index data), so resource errors should not cause
it to end. Instead, it should suspend itself and retry later. |

fail, if it encounters a resource error. |
