WL6.1 SP2, Oracle 8.1.7, OCI, ConnectionPool

Question

Hi,
i try to set up a database connection from a WL6.1 SP2 running on
Solaris 8 to a Oracle 8.1.7 DB running on Linux. I have to use the
Oracle - Driver, not the Weblogic - Driver. CLASSPATH, PATH,
LD_LIBRARY_PATH, ORACLE_HOME and TNS_ADMIN are set correct
(hopefully). When I use the thin - drivers, everything works fine. Now
I want to switch to OCI and get the following error:
ORA-07217: sltln: environment variable cannot be evaluated
I know this error occurs because I did not provide an ORACLE_SID. But
why do I need to export ORACLE_SID, isn´t the SID provided by the
ConnectionURL?
Anyway, if I set the ORACLE_SID explicitely, I get:
ORA-01034: ORACLE not available
Do I need to export the ORACLE_SID? If yes, why do i get the 01034?
The tnsnames.ora is correct, I can connect by using sqlplus to the
database without any problems ...
Here is the definition of the connection - pool:
<JDBCConnectionPool DriverName="oracle.jdbc.driver.OracleDriver"
LoginDelaySeconds="1" MaxCapacity="10"
Name="BMSP JDBC Connection Pool"
Password="{3DES}LFkEplP7jUuI/nVqSwNNjQ=="
Properties="user=vgn_data;dll=ocijdbc8;protocol=oci8"
RefreshMinutes="5" Targets="sgw-domain-server"
TestConnectionsOnRelease="true"
TestConnectionsOnReserve="true"
TestTableName="dual" URL="jdbc:oracle:oci8:@TESTDB"/>
Any hint is very welcome.
Thanks in advance,
Jochen

Hi,
ok, I solved the problem, it was a "classic" version - conflict. The
drivers (classes12.zip) came from an 8.1.6 - Version, but the
libraries were all 8.1.7. Mea maxima culpa ;)
Anyway, it was hard to find this error, because the errormessages did
not point to a version - conflict ... so, if anyone of you out there
encounters the same strange behaviour: Check your versions ;)
