Applies to:

Oracle Tuxedo System and Applications Monitor (TSAM) - Version 12.1.1.1 and later
Information in this document applies to any platform.

Symptoms

The Tuxedo TSAM Plus manager required database connection is the number of threads + some administrative connection from console(it is less than 5)

However, when many users are logging into the TSAM console it requires many database connections and requires over 10 administrative connections.

When a database connection limit is reached an exception like the following is seen:

<openjpa-1.1.1-SNAPSHOT-r422266:1445923 nonfatal general error>
org.apache.openjpa.persistence.PersistenceException:
weblogic.common.resourcepool.ResourceLimitException: No resources currently
available in pool tsamdc to allocate to applications, please increase the
size of the pool and retry..
