Hi Wally, I don't see a dedicated document for DB2 from Scale document sets, however, usually the workloads of database are doing direct I/O, so those documentation sections in Scale for direct I/O should be good to review. Here I have a list about tunings for direct I/O for your reference. https://www.ibm.com/docs/zh/spectrum-scale/5.1.1?topic=fpo-configuration-tuning-database-workload s https://www.ibm.com/docs/zh/spectrum-scale/5.1.1?topic=applications-considerations-use-direct-io-o-direct https://www.ibm.com/docs/zh/spectrum-scale/5.1.1?topic=mfs-using-direct-io-file-in-gpfs-file-system Regards, The Spectrum Scale (GPFS) team ------------------------------------------------------------------------------------------------------------------ If you feel that your question can benefit other users of Spectrum Scale (GPFS), then please post it to the public IBM developerWroks Forum at https://www.ibm.com/developerworks/community/forums/html/forum?id=11111111-0000-0000-0000-000000000479.

Is there documentation about tuning DB2 to perform well when using Spectrum Scale file systems? I'm interested in tuning both DB2 and Spectrum Scale for high performance. I'm using a stretch cluster for Disaster Recover (DR). I've found a document, but the last update was in 2013 and GPFS has changed considerably since then.
