Re: Custom TCP server after Restricted State

As far as I can tell by examining the DSPLOG output, the proper subsystem is started and TCP is started. Tomcat does not need HTTP services running; it's an independent server of HTTP.

I used ADDTCPSVR...AUTOSTART(*YES) to define the server, so it runs whenever TCP services are started.

hi Jason,

I don't understand the OVRDBF commands in your CL program... OVRDBF
doesn't affect code that runs in a submitted job.

You say that this runs automatically at IPL, or as part of a GO SAVE,
opt 21 backup. That implies that this is being run as an auto-start job
in the QCTL subsystem (or another controlling subsystem), right? Or is
being called from QSTRUPPGM (which, itself, is an auto-start job in the
QCTL subsystem...)

That being the case, it's easy for this to fail due to timing. QSYSNOMAX
might not be available. Or TCP/IP might not be. Or QHTTPSVR... it's tricky.

Instead, consider adding this as an auto-start entry on the QSYSWRK
subsystem. That's what Zend does for Zend Server, and it seems to work
well.

I have a CL program that I use to define a Custom TCPSRV for starting
Tomcat 6.0.30. When the machine is up and running, the STRTCPSVR
*TOMCAT runs with no errors.
After the machine leaves a restricted state (IPL/ Opt 21 Backup),
however, the command fails and prevents other startup jobs from running.
Those startup jobs have to manually be executed.

Any ideas why this may occur? I have included my CL code below.
