Hi

I got the following message in the CHIN log on Z/OS:

19.14.36 STC12128 +CSQX208E <stuff deleted> CSQXRESP Error receiving data, 964
...
964 TRPTYPE=TCP RC=00010101

Problem: I can't find a description of this return code. The Z/OS messages and codes manual lists a few TCP/IP return codes and refers one to "TCP/IP Messages and Codes manual". The closest I could find to that was the "z/VM TCP/IP Messages and Codes manual" which does not have RC=00010101 either.

So then; there does not seem to be a great problem with the system since the channel recovered itself but one would like to think that all return codes are described somewhere.

Adam.

the closest i could find was this one:

Quote:

WSAEDISCON
(10101)
Graceful shutdown in progress.
Returned by WSARecv and WSARecvFrom to indicate that the remote party has initiated a graceful shutdown sequence.

and one hint at ibm site that there may be a stop channel with force option.
maybe a look into the log of the remote end will help.

This looks to me like a Windows error code (many all Windows TCP/IP begin WSA).

Unfortunately TCP/IP return codes are platform specific. On one platform 10101 (decimal) means one thing and on another rc 78 means something else.

I am not sure whether the return code 00010101 is in decimal, hex or binary on the example given. Binary makes it 21, hex makes it 65793. Do any of these codes exist in the z/OS TCP/IP error codes manual.

Doing a search of IBM's OS/390 manuals I find the following location that contains a reference to error code 10101:

http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/ezap1004/C.2?SHELF=&DT=19970730010745&CASE=

Hope this helps.

Thanks to responders.

The RC is supposedly hex. The communication is UNIX -> MVS.

The Z/OS Messages and Codes manual mentions under the description for error CSQX213E that: it might be 00010101, if the channel was stopped with mode FORCE

TCP/IP V3R2 for MVS: Messages and Codes Vol I says of 10101:
A STORAGE OBTAIN failed. Insufficient TCP/IP storage available.

In the first instance I am trying to determine if anyone did a stop channel mode(force). A complicating factor is that we had a few of these pop up between different client/server combinations during a window of some hours so it may have been a network glitch?

Adam.
