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 11.1.0.7 Orion wasn’t supported but in 11.2.0.1 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
(storax_aiowait)
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 11.1.0.0.0 is the last known working version, Orion 11.1.0.7.0 and 11.2.0.1 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.
