Problem IC68611
|
Status: Closed |
CONCENTRATOR CAUSES PERFORMANCE HIT FOR READ LOG AGENT DUE TO NEW LOG RETRIEVAL NECESSARY WHEN AGENT SWITCHES OUT. |
| product: |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 |
| Problem description: |
When DB2 needs to re-use an agent for a different connection, it
takes away the agent from an existing connection (in this case
the readLog agent). When we take away the agent and re-use it
for another connection, we are destorying the information about
which log file this agent was looking at (at this point we also
delete the retrieved extent). When the readLog connection is
active again, it is assigned a new agent, and since the previous
agent informtion was destroyed, a new log retrieve needs to be
done since we do not remember that we are using the same log
file as before. |
