Hi,
We are using WebSphere App Server AE 3.5.3 with DB2 6.1 sp5. Both are installed on an AIX box.
We have configured the appropriate datasource called "nssdb" in the WebSphere using the "com.ibm.jdbc.app" driver. we also
selected db2java.zip in "/home/db2inst1/sqllib/java12" .
When we run the servlet below, although we are able to get the Datasource object properly from the lookup, we are not able to get a connection
from the data source (using conn = ds.getConnection).
We get the follwoing errors:
when URL is jdbc:jta:db2 and JTA is enabled
Get connection statement from com.ibm.ejs.cm.JTADataSource@c758afe8 [nssdb]exception: java.lang.UnsatisfiedLinkError: no library db2jdbc (libdb2jdbc.a or .so) in java.library.path.
when url is jdbc:db2 and JTA is disabled
Get connection statement from com.ibm.ejs.cm.JDBCDataSource@2f03221f [nssdb]exception: Error loading JDBC driver: com.ibm.db2.jdbc.app.DB2Driver.
We have tried setting up vaious env variables such as
export
CLASSPATH=$CLASSPATH:/home/db2inst1/sqllib/java12/db2java.zip
LIBPATH=$LIBPATH:/home/db2inst1/sqllib/java12:/home/db2inst1/sqllib/
LIB=$LIB:/home/db2inst1/sqllib/java12:/home/db2inst1/sqllib
LD_LIBRARY_PATH=$LD_LIBRARY_PATH/home/db2inst1/sqllib/java12:/home/db2inst1/sqllib
DB2INSTANCE=db2inst1
NONE of the above has helped.
The support doc "http://www-4.ibm.com/cgi-bin/db2www/data/db2/udb/winos2unix/support/document.d2w/report?&fn=1008029"
ALSO DID NOT HELP.
Copying lbdb2jdbc.so to the "/usr/WebSphere/AppServer/bin" directory helps: The "UnsatisfiedLinkError" goes away but then we
get another error: Get connection statement from com.ibm.ejs.cm.JTADataSource@c758afe8 [nssdb]exception: SQLAllocEnv() Error: rc = -1.
Can anyone help? May be you can forward this to somebody who could?
