Network Adapter Problem

[Anja Müller]

Hello,

I'm trying to connect to an Oracle database version 8.1.6 on a Solaris
(v2.6) server from a NT (v4.4) server via JDBC Thin Driver. When trying
to allocate the connections with connection pooling sometimes I get the
following error in the logfile of my application:

ConnectionPool xxx: failure allocating connection for
allocateConnections() from (unknown). Will sleep for 5 seconds.
Throwable: java.sql.SQLException: The Network Adapter could not
establish the connection

The listener seems to be up (listener status is ok), but nevertheless
restarting the listener solves the problem for the moment.

Does anybody know this problem and a better solution than restarting the
listener via cronjob?

Best regards,
