Hello all. I'd like to find a way to force my tomcat instances to get new 
connection pools, without stopping and starting the instances and kicking out 
all of my connected users.

I'm using Oracle RAC with a failover service, and should one node fail, our 
tomcat instances don't reconnect automatically. Doing a full stop/start can be 
time consuming, so I was wondering if it were possible to make them reconnect 
without a full restart.

I'm running tomcat 5.5.12 on RHEL4 with JDK1.5.

Thanks in advance...

If you're already paying a bunch of money for RAC, then use the RAC features

<Resource
  name="jdbc/test"
  auth="Container"
  type="oracle.jdbc.pool.OracleDataSource"
  factory="oracle.jdbc.pool.OracleDataSourceFactory"
  connectionCachingEnabled="true"
  connectionCacheName="ConnectionCache"
  fastConnectionFailoverEnabled="true"
  ONSConfiguration="nodes=oraclehost1:1521,oraclehost2:1521"
  ....

there are a bunch of other attributes that are Oracle specific, and this will get you what you want
