  • 1.  BUFFER POOL ISSUE ON A DB2 PURESCALE ENVIRONMENT

    Posted 2 days ago

    Hi Team,

    We are facing a critical issue where our Db2 pureScale database instance is unresponsive and failing a query  with the error.

    [57011][-1218] There are no pages currently available in bufferpool "2".. SQLCODE=-1218, SQLSTATE=57011, DRIVER=4.33.31

    Problem Summary:

    • All queries are failing with SQLCODE=-1218 (There are no pages currently available in bufferpool)..

    • A full database deactivate/reactivate cycle did not resolve the issue; the error returns immediately.

    • We have turned on Self Tuning Memory Management

    Hi!
    Sharing DBM CFG, DB CFG for DB <dbname> would be a good starting point - as well as Db2level.

    Did you look into possible resolutions for SQLCODE -1218:

    1. increase the bufferpool size

    2. decrease the maximum number of database agents and/or connections

    3. decrease the maximum degree of parallelism

    4. decrease the prefetch size for table spaces that are in this bufferpool

    5. move some table spaces into other bufferpools.

    Hi,

    1) What's the output of the following command on your server (amend the mydb to your database name)?
    db2pd -db mydb -buf 2

    2) Have you tried to set some initial value to this BP like below, if it's too small (the instance restart is needed)?
    db2set DB2_OVERRIDE_BPF=2,10000
