Applies to:JDBC - Version 22.214.171.124.0 and later
Information in this document applies to any platform.
After upgrade to 126.96.36.199 JDBC OCI drivers (full client and ojdbc7.jar with JDK 1.8), markedly slower performance is seen, specifically in the OracleOCIConnectionPool.getProxyConnection() method.
A java program using the OCI Connection Pool takes a long time to get a connection from the pool using ociPool.getConnection() on Windows platforms.
The time varies from a few msec to 5 or 10 seconds, depending on the entries in sqlnet.ora.
If no sqlnet.ora is defined in the environment, the program takes 10 seconds.
If sqlnet.ora is defined in the environment, and NAMES.DIRECTORY_PATH is set to more than one entry like: NAMES.DIRECTORY_PATH = (TNSNAMES,EZCONNECT), the program takes 5 seconds.
If NAMES.DIRECTORY_PATH is set to only one entry like NAMES.DIRECTORY_PATH=(TNSNAMES), it takes only a few msec.
The delay is not seen on Linux.
