Can SAS end users use code to clean up CAS memory

mpirritano — Fri, 02 Feb 2024 16:58:23 GMT

I've been adding data to what I thought were temporary cas tables. But after several sessions I'm getting the below error that i'm out of memory

Cloud Analytic Services failed writing to system disk space. Please contact your administrator. No space left on device

I've submitted a request to our administrator to clear it out. But is there a way for myself as an end user to clear it out?

thanks

matt

If you created or loaded the table then I would expect that you also have the permissions to drop or truncate the table.

For tables and data that you only need within a session I would also only create the table with session scope and not promote it. That will drop the table the moment your session gets terminated.

The error message you shared is about CAS_DISK_CACHE which for example gets used when CAS needs to move data from one node to another.

https://documentation.sas.com/doc/en/pgmsascdc/9.4_3.2/caspg/n09dk3dbd4xlccn18dl6i9be29hs.htm

This disk space is shared by all CAS processes and though it's not necessarily what you have been doing that caused the issue.

With Viya things improve quickly. Please always share the release you're working with.
