Accessing execution agent failed

Question

Hi!
I'm using Oracle 10g XE on linux. When I want execute any scheduler jobs get everytime the following error message:
ORA-27370: job slave failed to launch a job of type EXECUTABLE
ORA-27300: OS system dependent operation:accessing execution agent failed with status: 2
ORA-27301: OS failure message: No such file or directory
ORA-27302: failure occurred at: sjsec 3
The user privileges and owner of the extjob is set correctly.
The script runs on other servers without errors (on LINUX and WINDOWS too, but on 10g Enterprise Ed.).
This error seems to be the 'OracleJobScheduler service not runnig' in case of Windows, but here is no service. I could generate this problem by hand with renaming the extjob file in a goodworking system.
Could anyone help me in this problem? Why can't the oracle process see the extjob file?
Thanks for help

Hi,
What schema are you running the jobs in ?
In the SYS schema, the Scheduler uses the extjobo executable to execute jobs but I think on XE this executable might be missing so jobs in the SYS schema would be expected to throw this error.
You could fix this by simply doing something like
cp extjob extjobo
chmod 0755 extjobo
Or you could grant create job (and possibly create external job) to a regular user and have the user create the external job. I believe that in XE by default extjob is not setuid so all jobs would run as the oracle user. This may have security implications.
If this doesn't help could you say what schema you are running the jobs in and give the output of "ls -l extjob*" in the oracle bin directory.
Hope this helps,
Ravi.
