5315.0. "SYSMAN BROKE?" by CSC32::E_MOORE () Fri Mar 07 1997 01:27

Below is a problem description of one of our customers.  I did not have
the exact environment to duplicate his problem.  But any comments would
be greatly appreciated.  I did notice that this problem was seen in V3.2
of UCX. (note:2943,4383)

With five nodes in our cluster, it is very useful to utilize SYSMAN when
checking various system applications, e.g., NCP, SHOW MEM.

However, UCX$UCP commands don't work correctly.  It will show some data
correctly, but then switch to "graphics mode", displaying all sort of garbage.

For example,

$ MCR SYSMAN
SYSMAN> SET ENV/NODE=EMJVX0
SYSMAN> DO UCX SHOW COMM /MEM
%SYSMAN-I-OUTPUT, command execution on node EMJVX0

SYSMAN> EXIT

I don't know of any other product that does this (and it's only within
SYSMAN).
If I do the command at the DCL prompt, it works fine.

This really is a pain.

Thanks.

	This is not my area of expertise, but I'll try to answer this as Mike is out. I have done work in UCP in the past, and am now looking at the source, so here goes ... UCX$UCP uses SMG to format its pages of output. Even though the screen is not being used to provide update (i.e. like a MONITOR display of) information, SMG is being used to provide even printed-style (streamed DCL-like command) output. It has special code to deal with this. This code looks for CR/LFs in the data stream from SMG. When using SYSMAN, I believe it runs the commands on a mailbox. The mailbox does not have carriage control, which means that CR/LFs are not going to be provided by SMG. Therefore, it appears that there is a bug in the UCP code which deals with the SMG output on such as device. In order to get this fixed, you will have to submit an IPMT.
