Is there a timeout configuration on the portal for a connection on a database?  We have an issue where the portal gives me an error that the portal can't see a DB2 database. 

Our DB2 Database is partition and the result can take a little longer to respond because of it.

Release : 4.8

Component : CA Test Data Manager

You can increase the time out using  the below property 

spring.datasource.tomcat.max-wait=30000(ms)  to a higher value

The change need to be done in application.properties  that is in  %TDM_PORTAL%\conf  folder.
