We had configured one of the oracle client by using legacy method but we are unable to start backup as it is showing active only, nothing is happening, it is not generating any channels, not getting any errors from log file. Backup is completing from client side (RMAN prompt) without error. But after attempting few backups for troubleshooting suddenly we got this error "Linux-x86_64 Error: 28: No space left on device" then we came to know from EMC networker team that this error related to DB or OS.
I have faced the same error for another oracle client also. (different database and server). Please guide us what to do and why it is happening. Is this really related to backup tool. Earlier we didn't faced this error while configuring through NMO wizard.
No space left of device, if caused on client side, usually means that somewhere you have file system full and process tried to use that file system. That would easy to check with df command for start. If you suspect something is wrong with backup configuration, you will need to share details of configuration first.
Thanks Hrvoje. I was expecting response from you. I was reading one article some how related to this error.
1. I copied the RMAN backup script in /nsr/res path of oracle client. Configure in Client's Saveset attribute as "RMAN:/nsr/res/scriptname".
2. Copied "nsrnmobkp" from /usr/sbin to another name:"nsrnmodbname" and then edited below parameter.
mentioned same "nsrnmodbname" in backup command attribute of client.
We are having total 3 oracle database, for one client it is working fine but for other two oracle client it is showing same error .......
a) make sure that oracle client has permissions to access that script
b) usually ORACLE_HOME is enough if connect string is present (eg. not using OS auth which appears to be your case)
c) your error does not need to be related to disk space - it might be very well "memory space" - see link
I would suggest to check link under c) and check it with both OS and Oracle guys.
