MX7 multiple instance jdbc data sources

Question

The data sources on my single instance install of MX7
(Solaris9, Oracle9i), using jdbc, worked just fine. In a single
instance install, the environment variables needed for jdbc
(ORACLE_HOME, TNS_ADMIN, etc.) go in the start script
$CF_DIR/bin/coldfusion. I've removed the single instance and
installed the multi-instance version of coldfusion. I've been
unable to get it configured correctly for jdbc. (The error message
when attempting to verify a data source is, "blah, blah, no
suitable driver available... please check the driver setting....").
It would appear the the same settings should go in the
$CF_DIR/bin/jvm.config file. I've done so but this does not help.
What file do these settings need to be put into or does
multi-instance require a different configuration for jdbc?

Answer 1

Hello,
A data source entry is for one single database, so if you have multiple database to connect into your application you must create 1 entry per database (eg: jdbc/database1 jdbc/database2)
If you want to manage transactions over multiple databases (2 Phases Commit) you should the distributed transaction coordinator (DTC) provided within OracleAS.
For these 2 points (multi DB and transaction) I am inviting you to read the chapter 4-Datasources) on the "Oracle Application Server Containers for J2EE: Services Guide"
