Last updated on FEBRUARY 27, 2021
Applies to:JDBC - Version 126.96.36.199.0 and later
Information in this document applies to any platform.
Two separate boxes have 2 applications deployed, one uses JDBC Thin driver 188.8.131.52 and the other uses C++ OCI driver.
Both the applications connect to a RAC 184.108.40.206 database and have the same sqlnet and OS parameters.
When the RAC interconnect between the two node-RAC is disconnected, all services failover properly and
new connections are created properly. However, existing connections are hanging and both the applications hang at:
