OBIEE 11g - NQSServer Executable Appears to Run Parallel SQLs (Doc ID 1991168.1)

Last updated on JANUARY 30, 2017

Applies to:

Business Intelligence Server Enterprise Edition - Version 11.1.1.7.0 and later
Information in this document applies to any platform.

Goal

When running BI Publisher reports that are pulling data through the RPD data source, NQSserver.exe appears to spawn massively parallel SQL statements in the database, sometime 32 parallel server processes for a single SQL.

This overloads the database server, because when four or five BI Publisher reports are running at the same time, there are then more than 150 user processes which the system cannot accommodate.

How can these parallel SQLs be stopped?
