Re: Starting TCP

Thanks.

I should have looked there. Got hung up on looking for a STR command.

So, the STRTCP command is likely doing nothing worthwhile.

Previously (2005), TCP had be manually started. IPL attribute was added to
include start of TCP, then had to disable STRTCP in QSTRUP.
We did know this for a while, TCP was trying to start twice, once from IPL
attribute and also from QSTRUP.
Caused many errors during IPLs until disabled.

Subject: Starting TCP

I'm confused. There is a startup job on the controlling subsystem.
Essentially the first thing it does is call QSTRUP. Then, it does STRTCP.
I retrieved the source of QSTRUP. Nothing about starting TCP in it.

This startup job, not from IBM, has a MONMSG CPF9999 following the STRTCP
command.

I thought that TCP would have to be up before the LAN console would be
available. This STRTCP was added locally to the vendor code back in 1998.

Two questions:

1) When/how is TCP started?
2) Is this STRTCP doing anything or just a relic from a long time ago?

I believe this modification dates back to when we were on a CISC box and
just starting on networking.

Currently at v5r4m0.

I can explain why I was looking, but it started with a request from the
boss.
