Hello, I have a Oracle RAC, with 2 nodes (Oracle 9i under AIX). Is it possible that in a jdbc connection (an application under Apache Tomcat) I can choose the primary server where it may connect? I have in the jdbc connection: "jdbc:oracle:thin:@ (DESCRIPTION=(LOAD_BALANCE=on)(FAILOVER=on)(ADDRESS=(PROTOCOL=TCP)(HOST=10.xxx.xx.x1)(PORT=1521))(ADDRESS=(PROTOCOL=TCP)(HOST=10.xxx.xx.x2)(PORT=1521))(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=xxx)))" I have the same in my tnsnames.ora. If I put x2 before than x1, it uses the x1 again ... I want that it connects to x2 firstly, and if it fails, it uses x1 ... I'm sorry for my bad english :-) Thanks beforehand. Cheers...
