Applies to:JDBC - Version 184.108.40.206 to 220.127.116.11.0 [Release 11.1 to 11.2]
Information in this document applies to any platform.
High CPU usage on application using JDBC 18.104.22.168 (in this case OAM 22.214.171.124 BP4).
The CPU load of the OAM managed server increases over time.
Top used threads show a common stack:
"Thread-47" prio=10 tid=0x00000000459fa000 nid=0x66b3 waiting on condition
This method is related with the Oracle JDBC Driver at class "oracle.jdbc.driver.NTFConnection.readFromNetwork".
The result is a gradual increase in CPU consumption from 4 - 80%, in a two week period. After a restart, the cpu load is normal again; then it rises again in a two week period.
