I have oracle 9i database running on HP UX 11.23.
We are using Vxfs.
We have a problem with the permissions on /dev/async value this is getting changed automatically from 660 to 666. and this is causing asynchronous error in database.
Everytime we change it manually and it is changing back automatically we don't know when and how ?
Could any body please help. This is urgent.
Thanks
Rajeev

Re: /dev/async file permissions getting changed,
Check who has permissions on /dev/async
Check their keystroke logs for chmod.
Check their cron jobs for chmod commands.

Re: /dev/async file permissions getting changed,
To be able to troubleshoot this, you should first determine when the change is occurring.
Step 1.
========
Create a cron job that will run every hour and log the file permission status to a file which you can verify every now and then.
e.g.
ll /dev/async > /tmp/monitor_async.log
Step 2.
=======
After you have found when the change is occurring, verify your environment for all activities during that interval.
Btw, what error are you getting?
You may wish to read metalink note: "139272.1 - HP-UX: Asynchronous i/o"
Good luck.
kind regards
