SAS Enterprise Guide 5.1 Query Builder to Netezza Ghost Connections

[gxmessier]

  We have an issue where the connections, per user, to Netezza is currently limited to 12. Therefore if the user has 6 ghost connections that are not being cleared w/o shutting down SAS EG. This user is in effect only has 6 remaining connections available for the query builder project. Does anyone have a script that would clear these connection within the EG session w/o shutting down to clear. I know the easiest answer is to increase the number of connection to Netezza but our Netezza team is strongly against this proposal. Defer=yes does not function properly in query builder. Tested SAS EG 6.1 with the same results. Any other ideas would be deeply appreciated.

There was a hotfix just issued that might address this for EG 6.1M1:

Hot Fixes for SAS Enterprise Guide 6.1_M1

I don't see it listed in the SAS Notes for that hotfix, but I did see it mentioned internally in a tracked defect.  The particular situation involved using VIEWS instead of table output from the Query Builder in combination with database connections.

If that doesn't solve it for you, you should work with SAS Technical Support to track it down.

was this post a duplicate of this one? https://communities.sas.com/message/218995  first solve the configuration issues as mentioned.
The explicit pass thru with EG query builder can become a headache as difficult to prove and trace what is happening. The root cause problem is dedicated tuning of Sql generation to each DBMS.

Using views in query builder did not make a difference. Defer=yes also does not function within query builder.

To check:

a/ The defer=yes should be in libname definition for all users. It only saves netezza sessions for users that could go to netezza but are not doing that.
b/ The sharing of sessions should be set up and tested for each  user going to netezza. Every call can cause one or multiple netezza sessions, it is better to maximize this usage for 1 shared read.

    SAS/ACCESS(R) 9.4 for Relational Databases: Reference, Third Edition (  unique is the default setting for the connection=  SAS/ACCESS(R) 9.4 for Relational Databases: Reference, Third Edition (LIBNAME Statement Specifics for Netezza) This will cause many sessions to be openend to Netezza (same with other RDBMS ones).

c/ The use of the EG query builder can be done of the use of libnames or with explicit pass though.

    The use of libnames is more easy with EG not needing building a new netezza session. It has the disadvantage of possible SQL problems ANSI/Netezaa specific. Sharing netezza sessions between libnames is another topic.

    Use of SQL-pst will cause additional netezza sessions and the EG-builder can fail to generate correct netezza SQL.

How far did you come in pinpointing your problem?

I only read "defer=yes" does not help and the netezza DBA is not helping with higher limits,12 is really a low limit. Saying netezza is not able to support more than 12 concurrent users.

What about all other config settings and debugging their effects?  Running SAS with EG6.1 could cause multiple SAS sessions being used (parallel execution) each of them needing a netezzaa connection.
