Program querying DAS for isntances/databases

[byrocat]

I have a tool that's trying to locate DB2 instances via the DAS, but
apparently is not finding them, even though the IBM tools say taht the
DAS is up and running and BTW, here's the list of instances on the
server.

I managed to monitor the network traffic to see what is going on, and
spotted something that looks odd in the data stream. The tool attempts
to connect to the DAS (ome message goes out and there's a response),
then the second message goes out and this comes back:

00000 00 a3 00 00 00 00 00 00 53 51 4c 44 42 32 52 41 ........SQLDB2RA

00090 00 00 00 20 20 20 20 20 20 20 20 20 20 20 20 20 ...

Where can I go to find a detailed description of the messages that are
being sent and received?

At first glance, it really looks as though the second outgoing message
is not correct. Alternate is that the DAS may have been changed subtly
to be black-and-white on messages.

Thanks in advance!

It appears that you are using V7. Is it correct?

What API you are trying to use?

Proper way to list DB2 instances is to execute as a priviledged user (root on
Unix, System administrator on Windows) db2ilist.

I need to do this remotely, via port 523 using TCP/IP.

As far as I know - DAS does not have externalised API - hence you have to rely
on GUI interface with DISCOVERY SEARCH.
