By the description this is similar to a typical connection pool issue with
lack of use for several hours, the connections are closed by the database
end, the connection pool has no way to know, and grabbing the connection
ends up having to time out, with everything locked up (if you have a
validation query, otherwise it fails in other ways).
Do you have the validation query setup in your JNDI connection pool?
Also, what about the followoing params, that we are setting up in our
normal data stores, that are there to deal with the issues
of connections not being used for several hours? (sorry for pasting code,
today is a holiday in Italy, have to be expedient as I'm
getting out of the house):
Boolean testWhileIdle = (Boolean) TEST_WHILE_IDLE.lookUp(params);
if(testWhileIdle != null) {
dataSource.setTestWhileIdle(testWhileIdle);
}
Integer timeBetweenEvictorRuns = (Integer)
TIME_BETWEEN_EVICTOR_RUNS.lookUp(params);
if(timeBetweenEvictorRuns != null && timeBetweenEvictorRuns > 0) {
dataSource.setTimeBetweenEvictionRunsMillis(timeBetweenEvictorRuns * 1000l);
}
Integer minEvictableTime = (Integer)
MIN_EVICTABLE_TIME.lookUp(params);
if(minEvictableTime != null) {
dataSource.setMinEvictableIdleTimeMillis(minEvictableTime *
1000l);
}
Integer evictorTestsPerRun = (Integer)
EVICTOR_TESTS_PER_RUN.lookUp(params);
if(evictorTestsPerRun != null) {
dataSource.setNumTestsPerEvictionRun(evictorTestsPerRun);
}
Cheers
