Hello *,

I've got a new machine here, and there are some difficulties with them, i now begin to suspect they are hardware related, but i don't know how to prove it. The Oracle 10.2.03 redhat linux 64bits machine crashed this morning. Upon the reboot i did, it seemed all back to normal. However, trying to add a datafile went wrong:

idle> alter tablespace cdrstorage add datafile '/oradata02/xxx/ storage07.dbf' size 16384M ;

alter tablespace cdrstorage add datafile '/oradata02/xxx/ storage07.dbf' size 16384M
ERROR at line 1:
ORA-19502: write error on file "/oradata02/xxx/storage07.dbf", blockno 9
ORA-27072: skgfdisp: I/O error
Linux Error: 2: No such file or directory Additional information: 986496

Does anyone know what the 'Additional information: 986496' means? The IO was a bit of a problem anyway, with IO value's which were too low for these 10k rpm SAS disks.
Any advice on these errormessages is welcome.

ps i also saw a lot of
" WARNING:Oracle process running out of OS kernel I/O resources" messages in the dumpdirectories, but there were only a few hits on metalink on this and no bugfix or workaround is presented. Received on Wed Jan 23 2008 - 06:29:37 CST
