BatchServer and autoexec

MariaD — Thu, 28 May 2020 18:25:41 GMT

Hi folks,

We are making some test using the following command line to execute on batch.

/sas/config/Lev1/SASMain/BatchServer/sasbatch.sh -log /path/log.#Y_#m_#d.log -batch -noterminal -logparm "rollover=session" -xcmd -sysin /path/program.sas &

The test SAS program only copy a SASHELP.CLASS table. After reviewing the generated log, we identified some libname definitions on it. We reviewed the autoexec included on BatchServer folder and the autoexec is empty. We reviewed the autoexec included on /home/user folder and is empty too. How could I identify which autoexec used?

Regards,

Hi @MariaD ,

Do you have any pre-assigned libraries associated to the SASMain application server context? These would be loaded during startup by way of the METAAUTORESOURCES option in SASMain/sasv9.cfg. The autoexec files sourced are those for the context and the Batch Server specifically. i.e. SASMain/appserver_autoexec(_usermods).sas and SASMain/BatchServer/autoexec(_usermods).sas.

You can identify these by following the autoexec option. sasbatch.sh sources BatchServer/sasv9.cfg which contains the autoexec option pointing to BatchServer/autoexec.sas. That file sources autoexec_usermods.sas and ../appserver_autoexec.sas, which sources ../appserver_autoexec_usermods.sas.

These are pre-signed libraries. It is an option of the libraries registered in metadata.
To find out more, please consult: https://documentation.sas.com/?docsetId=bidsag&docsetTarget=p0u8xcdo2ll3kmn1oqfz2s0ybooq.htm&docsetVersion=9.4

Thanks @gwootton . There is any way to unable the METAAUTORESOURCES for specific process? Something like "-NOMETAAUTORESOURCES" to add in some config fiel or options METAAUTORESOURCES = NO...

Don't do that. There is a REASON why the application-server based context is also valid in the subservers, one of them being the batch server. After all, you expect that programs that work in the workspace server will also work in batch.

Thanks @MariaD

If you wanted to prevent it from assigning the libraries for a particular execution you could add an invalid option like -metaautoresources "foo" to the command line. This would produce the message:

NOTE: No preassigned object definitions were found on the metadata server.

As @Kurt_Bremser pointed out, the pre-assigned libraries are supposed to be assigned for any server started from that context so it may not be desirable to prevent these from assigning all the time by modifying the configuration file.

If you don't want them to be assigned ever for any server session, you can remove the pre-assignment from the libraries in SAS Management Console. If you do not want them to assign for particular users, you can deny ReadMetadata permission to the library for those users. This could be helpful if you are running your batch jobs as a particular user.

Thanks folks! Yes, for some executions, because we have a lot of external libname that takes time, we preferer to exclude it. Regards,
