ORA-27061 with Oracle Orion (the I/O benchmark)

Filed under: Oracle — datatombraider @ 20:57

To benchmark and verify the storage for a new RAC installation i used Oracle Orion. Until Orion wasn’t supported but in Orion is part of the RDBMS installation, so i guess it’s supported now.

Orion runs just fine until it comes to random large i/o:

ran (large): VLun = 0 Size = 2914705735680
Error completing IO
ORA-27061: waiting for async I/Os failed
Linux-x86_64 Error: 14: Bad address
Additional information: -1
Additional information: 1048576
lun_aiowait: storax_aiowait failed.
rwbase_run_test: rwbase_reap_req failed
rwbase_run_process: rwbase_run_test failed
rwbase_rwluns: rwbase_run_process failed
orion_thread_main:rwbase_rwluns failed

Orion is the last known working version, Orion and both fail with the above error. Oracle development is still working on it (since Nov 2009 šŸ™‚

Update: Oracle finally fixed the bug with patch 9104898.
