Hello guys,

I'm facing a error which I've never come across.

We have a backup script scheduled to run from a batch file, it is currently giving me a TNS Adapter Protocol Error. Normally I'd think the service isn't running but oddly enough double clicking the batch from windows explorer runs as expected. Anyone knows of anything that executes differently from task scheduler and can help me with this? Thanks in advanced.

The most common cause is the script is picking up something from *your* environment (eg ORACLE_HOME or PATH etc) that is not being set when run from the scheduler.

So perhaps try adding something like this to the start of your script:

set ORACLE_SID=db122
set PATH=C:\oracle\product\12.2.0.1\bin;%PATH%
set ORACLE_HOME=C:\oracle\product\12.2.0.1

(obviously using values appropriate to your system)

and *then* call rman or sqlplus etc

Wow... On spot!

I thought Task Scheduler used the user's environment variables to execute it's tasks, guess I was wrong...

Adding those set commands to my batch solved the issue.

Thank you for your time! :D
