Hi,
looks like the db ure accessing has some time out for connections and the server can�t refresh it, check with dba about it.

in fact i checked DBA and my DBA saying nothing wrong with oracle something wrong with weblogic or code.
weblogic_console.log is giving this error
Database Connection error java.lang.NullPointerException

Is something to do with ThreadCount attribute of an ExecuteQueue element in the config.xml file

Hi,
there�s this troubleshoting note on weblogic documentations, maybe this can help u.
Youmay also encounter a shared library problem if you do not include the proper paths
in your SHLIB_PATH when using Oracle 9. SHLIB_PATH should include the path to
the driver (oci901_8) and the path to the vendor-supplied libraries (lib32). For
example, your path may look like:
export SHLIB_PATH=
$WL_HOME/server/lib/hpux11/oci901_8:$ORACLE_HOME/lib32:$SHLIB_PAT
H
Note also that your path cannot include the path to the Oracle 8.1.7 libraries, or clashes
will occur. Formore instructions, see SettingUp the Environment for UsingWebLogic
jDriver for Oracle at
this place

Hi Marcos,
Thanks for that. I checked everything. everything is fine. when the db operation fails sometimes ( not always) is not giving ant msg at weblogic.log .The only msg is in weblogic_console is
Database Connection error java.lang.NullpointerException.
Db operation is not failing everytime happening once in 50. addBatch method is implemented in that page.
