Re: Upgraded to OS 6.1, Shell not working

Kurt, I should clarify that in my case, our firewall was causing the initial QSHELL problem. With the same firewall situation, QSHELL still wouldn't have worked, even if I had RDP. The fix in RDP was just so java.exe wouldn't go nuts CPU-wise once the firewall blockage occurred. So, if there is a firewall situation in your environment and you address that (by authenticating to the firewall, etc), QSHELL should work for you OK in WDSC. WDSC will hang if you ever hit a firewall problem again. RDP will handle a firewall blockage more elegantly w/ no resulting java.exe hang.

As it turns out, the remote shell did start, and proceeded to suck up system usage. I didn't notice any system slowdown yesterday, but today the response time was atrocious. Went to find what was sucking down the system, and oh look, two remote shell jobs. I guess I just won't use remote shell until I get RDP (which will hopefully be soon). Waiting for the upgrade pains to subside before approaching management about it.

Subject: [WDSCI-L] Upgraded to OS 6.1, Shell not working

I had something like this happen once. In my case, java.exe also hung
and drove up CPU. RDi 7.1 had the fix for the actual hang, however, my
root cause with QShell not working was a firewall situation in our I/T area.

A Verify Connection operation
<http://archive.midrange.com/wdsci-l/200803/msg00206.html#>, or trying
to run STRRSESVR from your i5/OS command line might confirm if you have
a firewall situation concerning server callbacks to the RSE daemon. When
I authenticated to my firewall environment, then the QShell subsystem
worked OK for me - there is a callback from i5/OS to the PC running WDSC
involved
with the QShell subsystem/view.

In my case, when the TCP/IP
<http://archive.midrange.com/wdsci-l/200803/msg00206.html#> interface on
i5/OS is restarted, I needed to re-authenticate with our firewall. The
OS upgrade would have restarted your TCP/IP interface. It took a while
to figure out what was going on in our environment, because QShell had
worked before, and I couldn't figure out why it stopped working.

For instance, I usually compile java source from WDSC 7.0.0.8, but now the shell opens but none of the commands issued are processed. There isn't a prompt either. I think it used to be a> (in qshell through the green screen it's a $).
