Oracle8i and Oracle9i with BWLS5.1

Question

Hi, I need help!!!
I ve a Oracle8i and an Oracle9i connection pools in WLS 5.1
The Oracle9i connection pool is not stable, and have been told to upgrad the drivers for it. I wonder if there is any problem use connection pool to an Oracle8i and Oracle9i, without any conflicts.
Can WLS5.1 handle it? how should I do ?
Pleaaaase!

Hi Sree,
Sorry, I was wrong, I found the JDBC drivers for the Oracle9i.
The JDBC pack contains the OCI and Thin drivers.
Thanks alot.
best regards, John.

Hi Sree,
thanks alot for your help!
I was looking for Oracle 9i Thin driver, but could not find any!
The only I could find was Oracle 9i thin JDBC driver for Mac OS X.
and thanks again for your help.
regard, John!

Hi John,
WebLogic jDriver for Oracle 9i is not available for WLS5.1. Its only
available for WLS6.1SP2 and above.
I suggest you use the Oracle thin driver from Oracle to connect to the
9i
database.
when you download and install the 9i thin driver, the connection pool
can be
configured as,
weblogic.jdbc.connectionPool.O9iPool=\
url=jdbc:oracle:thin:@9imachinename:port:SID,\
driver=oracle.jdbc.driver.OracleDriver,\
loginDelaySecs=1,\
initialCapacity=5,\
maxCapacity=12,\
capacityIncrement=2,\
allowShrinking=true,\
shrinkPeriodMins=15,\
refreshMinutes=12,\
props=user=o9iusr;password=o9ipwd;weblogic.oci.min_bind_size=660
You cannot use two different OCI drivers at the same time to create
Connection pools in a single server.

Hi Sree, thanks for your help... now this information is what I got.
Some data:
ORACLE_HOME=/oracle/product/8.1.7
PATH includes $ORACLE_HOME/bin
My ld library path include the oracle driver: oci815_8:$ and ORACLE_HOME/lib
As I can see is the oci815_8 in use.
weblogic.jdbc.connectionPool.O8iPool=\
url=jdbc:weblogic:oracle,\
driver=weblogic.jdbc.oci.Driver,\
loginDelaySecs=1,\
initialCapacity=5,\
maxCapacity=12,\
capacityIncrement=2,\
allowShrinking=true,\
shrinkPeriodMins=15,\
refreshMinutes=12,\
props=user=o8iusr;password=o8ipwd;server=O8iServer;weblogic.oci.min_bind_siz
e=2000
weblogic.jdbc.connectionPool.O9iPool=\
url=jdbc:weblogic:oracle,\
driver=weblogic.jdbc.oci.Driver,\
loginDelaySecs=1,\
initialCapacity=5,\
maxCapacity=12,\
capacityIncrement=2,\
allowShrinking=true,\
shrinkPeriodMins=15,\
refreshMinutes=12,\
props=user=o9iusr;password=o9ipwd;server=O9iServer;weblogic.oci.min_bind_siz
e=660
Now Can I Make Tow Connection Pools To Oracle With Different Drivers
Like Let The O8i Go To The Old oci815_8 Drivers,
And Install New Oci Drivers For The Oracle9i ??????

Can you post the connection pool properties url and driver, they should
tell
us what driver you may be using.

Hi,
I dont know exactly what driver we use, but I know that the same driver
is
in
use for bothe 8i and 9i. And I know that the driver is old, (from 2000).
The behavior is that connection duo the 9i are rollin back sometimes,
about
30%
of all transactions are rolling back.
Thats why I ve been told to use newer drivers (9i drivers).
So, yes, I see exceptions, roll back exceptions of the transactionsthat
are
trying
to connect to the database pool.
But I wonder how to do that, and how can I see exactly what driver
we
use
now?
Please help me!!!!

John,
What driver are you using to connect to 8i and 9i? What is the behavior
you
are seeing with the pool connections, when you say pool is not stable?
do
you see any exceptions/hangs ?
Also ensure that you have testConnsOnReserve=true (on the 9i pool)
so
that
the connections get recreated if they go bad.
