Hi,
I have workflows accessing DB, DB connection created through following steps:
1. Define a datasource stanza in odbc.ini, say [ABC]
2. Set the new datasource stanza into broker by issuing command:
mqsisetdbparms Brokr -n ABC -u abc -p xyz
3. Create a Database node, and specify Data source name: ABC for the node.
This method is working perfectly for workflows.
There is another way of accessing db from workflow by creating a configuration service:
mqsicreateconfigurableservice Brkr -c SecurityProfiles -o ABC -n XYZ .....
and then invoked the service within workflow (not sure how exactly it is done, as I'm not the developer...)
Question now are:
1. What's the difference of these 2 methods in terms of performance etc?
2. What's the reason behind of "mqsicreateconfigurableservice" method to access db?
Thanks ....

Nothing. 2 ways of accessing the same db driver.

On a lot of platforms, changing odbc.ini requires a broker restart to be effective because of the way the platform handles database connections. Moving it to a configurable service removes this restriction, and this is why they were introduced in IIBv8 (v9? One of those).
