Hi: One or two sessions waiting for library cache lock for long time(in days). Most of the time the session waiting for library cache lock is trying to parse (based on v$sql.sql_text) a SQL statement. Everyday we identify the session and kill the session in both oracle and unix. There are two databases with 2 node OPS and all 4 nodes has the same config. The library cache lock is always on the Node-1 of the 1st database from application A1. Java application is connecting to the database using connection pool(OCI client). There are 3 connection pools for 3 different applications. Version 8.1.7.3 Could someone through light on this? Thanks -Sami -- //www.freelists.org/webpage/oracle-l
