How to set concurrent connection limit on ODBC library

AsakoOkano — Wed, 24 Jul 2019 09:15:04 GMT

I have SAS9.4 Intelligence platform environment connect to other RDBMS with SAS Access Interface ot ODBC.

I have ODBC database server and ODBC library resistered in metadata. I want to limit number of secession that connect outside of RDBMS at same time for server resource reason. Is there any way to cofigure the limitation of concurrent session on ODBC library?

thanks.

Isn't this something you'd typically restrict on the database side?

SAS sessions execute independently from each other and I'm not aware of any repository which registers active connections to a database. As such I wouldn't know how such a limitation could even get implemented on the SAS side.

Hi @AsakoOkano,

I haven't seen an option that can be given as integer value to limit connections to DB from SAS Side. This is something you can set on the DB configuration. However there are few options on SAS Side which you can use to optimize your connection to external database. This can be found under Advanced options -> Connection tab of the DB library.

This #SASGF paper has a nice tabular information on all the possible values for this option along with description.

Pg:8 Section: Connection Tab

Thanks!
