Last updated on MAY 24, 2016

Applies to:

Oracle Enterprise Data Quality - Version 12.2.1 to 12.2.1 [Release 12]
Information in this document applies to any platform.
Platform and Version: Oracle Linux 6
Java Version: JDK 1.8.0.66

Goal

Utilizing EDQ 12.2.1 deployed to Tomcat, whenever maintenance activity in a RAC database is present (perhaps as done on a rolling node reboot and using the database service in the JDBC URL), the following error is thrown:

[...]EDQ-01800] Error in database operation: IO Error: The Network Adapter could not establish the connection[...]

Restarting the Tomcat server whenever there's a RAC database maintenance activity is to be avoided by altering director.properties file.
