Hi guys,
We are trying to solve problem with DB connection recovery after TCP-IP link dropout.
When the DB connection (connected or connecting) isn’t used in time of network
failure, then the AS knows how to remove the ‘old‘ connection a and establish
the new one.
But quite different situation is when the DB connection
is just executing – info about network failure doesn’t go through JDBC driver to AS and the DB
connection remains blocked. This leads to total connection pool blocking with
appropriate unpleasant application consequencies. The only solution is AS
restart.
Configuration:
DB Informix, version 11.7, access via csm
Application server JBoss 0.7.1.1 Final
Informix JDBC driver 4.10.2
Any idea, experience or solution welcome …
p.
