Hello,

Preface: I would like to know the target database host/port. I'm using a user exit because I cannot modify existing flows. The user exit is intended to be put on existing installations for monitoring.

The only relevant node attribute I could find in the docs was the Data Source Name. This is the alias to the JDBCProviders configurable service. (Incidentally, the doc lists "dataSource" and is incorrect, cniGetNodeAttribute() required the keyword "dataSourceName").

1. I found the cniGetResourceProperty() API, however, what is the "resourceManager"?
CciSize cniGetResourceProperty(
int* returnCode,
CciChar* resourceManager,
CciChar* propertyName,
CciChar* value,
CciSize length);

2. The only other idea I had was to run
"iib mqsireportproperties node1 -c JDBCProviders -o AllReportableEntityNames -r" (with popen or boost.process) in bipInitializeUserExits() and parse the output. With that I can create a lookup table for the dataSourceNames. I do NOT like the idea of executing this on the command line and am hoping for any ideas.

Thanks!

Given the chaos & misery you can cause with a user exit that has one trivial coding issue, I'd absolutely use the command (which is intended for the use case you outline)

What causes you to find it unpalatable?

It seems backwards to me to run a shell command(mqsireportproperties) from the user exit rather than using the supposedly equivalent API (cniGetResourceProperty).

I've gone ahead and coded up the shell command in my user exit. While it's still backwards to me, it works.

Thanks.

Sorry - what I meant was why use a user exit at all!

A user exit in IIB is not a good thing; I accept your example is fairly vanilla but what I was getting at was why use an exit at all. Why not simply run the report command external to IIB and avoid the risk of a user exit?
