Welbogic 6.1 is losing jdbc persisted sessions

Question

          We are having a problem with WLServer 6.1sp2 apparantly losing http sessions when
          we use jdbc persistence to an Oracle 8.1.7i db. We are using the oci jdbc driver.
          Has anyone had similar problems??? (Note: if we switch back to memory session persistence
          things work fine, but we want to share the session accross two load balanced servers
          which are not in a cluster). Thanks, J
          

Answer 1

Can you try to change the driver and see if things start working? There are
          some known problems
          with Oracle's thin driver. We've updated the classes12.zip for the sp3
          release, which I believe
          fixed the problems. For now let us know if changing the driver fixes your
          problem.
          eg.
          <JDBCConnectionPool
          Name="poolname"
          Targets="serverlist"
          URL="jdbc:weblogic:oracle"
          DriverName="weblogic.jdbc.oci.Driver"
          InitialCapacity="3"
          MaxCapacity="10"
          CapacityIncrement="1"
          Properties="user=usr;password=pwd;server=xyz"
          />
          Also our driver expert suggested the following (with the oracle's driver):
          "Try to see if you can set the NLS_LANG env variable.
          Here is how:
          run the following sql from SQLPLUS:
          select parameter, value from NLS_DATABASE_PARAMETERS
          where parameter in ('NLS_LANGUAGE','NLS_TERRITORY','NLS_CHARACTERSET');
          check the output it may look like,
          NLS_LANGUAGE AMERICAN
          NLS_TERRITORY AMERICA
          NLS_CHARACTERSET UTF8
          therefore:
          export NLS_LANG=american_america.UTF8
          depending on the output you may see please set NLS_LANG accordingly and try
          you test."
