Message server does not give application server list via HTTP

When I go to the URL http://<messageserver>:<msport>/msgserver/text/logon or .../msgserver/text/aslist there are no application servers listed (just the version number). However if I go to the message server monitor (transaction SMMS), I can see the application servers.

Other ms URL commands work, such as .../msgserver/text/lglist. However I need .../msgserver/text/logon to work because this is how SAP Web Dispatcher queries the message server to find out which application servers are available...

Any help greatly appreciated...

Best regards

Jane

Hi,

Your problem seems very strange : I've never had any problems with the http commands from the message server.

What is your kernel release and patch level ? Which OS ?

Do you get any error messages in SM21 and in the DEV_MS trace file ?

Jane,

For the DEV_MS trace file, try this :

Increase the trace level with transaction SMMS --> Goto --> Trace --> Level --> Increase

Then try to call http://myMSserver:port/msgserver/text/aslist from your browser.

Then check the content from the DEV_MS file.

Hi Olivier,

The kernel release is 7.00 SP11. OS Windows Server 2003 Enterprise x64 edition.

I didn't see any errors in SM21 or dev_ms file.

I raised the trace level on dev_ms but not sure what is relevant !! I can't find anything relating to requests from the IP/hostname of the server I was on... or anything that looks like an error...

I was hoping maybe someone has come across it before, but I guess not!

Thanks

I found this in the dev_ms:

[Thr 6292] MsSGetLogon: get protocol

[Thr 6292] name = <MSGSERVER>_<SID>_00

[Thr 6292] prot = MS_LOGON_J2EE

[Thr 6292] MsSGetLogon: logon data MS_LOGON_J2EE for client <MSGSERVER>_<SID>_00 not set

[Thr 6292] MsSProcOpcode: error processing MS_GET_LOGON (MSOP_NOTSET)

could that be related to it?

Thanks

The root cause was there were two message server processes running on the server and the "wrong" one was answering the request. We had recently upgraded the backend and it turned out to be a side effect from that.
