I am running a telecom application on 3 red hat Linux servers. All server have same kind of settings. We have observed that one of the server throwing "No ManagedConnections available within configured blocking timeout ( 30000 [ms] )" when there is bulk INSERT/UPDATE on oracle database. But same amount of Bulk INSERT/UPDATE on oracle database is done without any Exception in rest of the two server.
We are using below jboss connection pool for db connectivity in all servers :
App related detail
Red Hat linux server
JDK 5 Update 22
The Exception occur maximum for 2 minutes but during this time lot of requests will fail. Anyone can give idea what is causing the particular server throwing this Exception while rest of the servers running smoothly.
