Last updated on MARCH 08, 2017
Applies to:JDBC - Version 220.127.116.11.0 to 18.104.22.168.0 [Release 11.2]
Universal Connection Pool - Version 22.214.171.124.0 to 126.96.36.199.0 [Release 11.2]
Information in this document applies to any platform.
Application is unable to use the UCP threadpool after a recent upgrade to JDBC 188.8.131.52 and UCP 184.108.40.206. Database version is 220.127.116.11.
Thread pool is at maximum capacity (24 in this case) due to waiting tasks, and UCP results in not allowing any further connections.
The issue occurs when Fast Connection Failover (FCF) is enabled.
