Monitors Freezing

[Anonymous]

We upgraded to CL 5.3 a couple of weeks ago (AIX 5.1).  Ever since we upgraded, we have been having problems with our Net monitors freezing.  The thread icons don’t always show the true status.  If we refresh they are okay for a while, but sometimes we have to refresh two or three times.  We did increase the buffer size, but it didn’t help.

Any suggestions?

TIA,

We are having the same problem here on all of our client pcs.  QDX5.2, AIX 5.  Shouldn’t it refresh automatically with the updated information?

Run hciserveradmin, click on advanced tab and try the settings in the attached file.

Basically, you are doubling your buffer size.

Make sure you don’t check Hostserver routes traffic!

Bounce the hostserver after making this change.

This runs fine on our 5.0 and 5.3 box (AIX)

Hope this helps,

How do you get to this GUI?  I typed in hciserveradmin from the command line and got a bunch of JAVA errors:

Exception in thread “main” java.lang.InternalError: Can’t connect to X11 window server using ‘:0.0’ as the value of the DISPLAY variable.

       at sun.awt.X11GraphicsEnvironment.initDisplay(Native Method)

       at sun.awt.X11GraphicsEnvironment.(X11GraphicsEnvironment.java:63)

This is just the beginning.  I am using a X-Window terminal session.

Maybe I can just edit the server.ini file (if that’s where this java argument goes).  What section does it go in and what’s the exact line I would add?

Thanks.

It sounds like you did it correctly.

Run hciserveradmin from the command line of your xterm session.

Then the login stuff should appear. Make sure your certs are in place.

I’ve had problems editing the server.ini directly before.

You may be able to get away with it.

It looks like you are having an xwindows problem.

See if you get the same error running tclhelp.

Kevin,

To manually add Michael’s settings you would add the following 2 sections to your server.ini.  Bounce the host server to make the changes effective.

[general]

jvm_args=-Xmx256m

[firewall]

monitord_server_buffer_size=320

monitord_server_use=false

[Traci Zee]

Cloverleaf 5.4, Rev1 on AIX 5.3

I’ve added the changes recommended to server.ini and bounced the Host Server.

When I launch NetMonitor I get cannot connect to monitord due to the exception below: Connection time out: Connect

I expect that I have a firewall issue but don’t know what to change to resolve it.  Any suggestions?

TIA

I have had an issue similar to the one that started this thread, so I am giving this solution a try also.   A few questions:

What does Host Serve Routes Traffic do?     I am using Advanced Security and the user guide 2 says use the default setting to receive monitord traffic directly, but it also says “By default, Host Servers route MonitorD traffic for Basic and Advanced Security.”    What traffic is it?   Not message traffic?

For the java heap argument, how would I determine the “maximum number of megabytes want to be allocatable to the Java heap.”?

For the person who is experiencing X-windows issues.   I had to deal with this a week ago and to avoid any more headaches for people, here are some tips.  

We run Cloverleaf on IBM AIX (Unix 5.3) and we use the Cloverleaf Client on Windows to communicate.  Some utilities like hciupgradeutility, hciserveradmin on the UNIX servers require GUI windows.  

I installed Cygwin/X on my PC. Cygwin/X is free and an is an X-Window emulator that is for Windows.  Once installed, please start the X-Win server and type

xhost +

Here is a sample session on my PC:

---

axr143@WMDCINT02 ~

$ xhost +

access control disabled, clients can connect from any host

---

Some security folks may balk at the result above but make sure you dont enable this for a long time. Just close X-Win server as soon as your done.

Now, on the UNIX machine, you need to type this

---

> export DISPLAY=172.22.35.22:0

---

Obviously, your PC’s IP address needs to be input there

Now, , you can type

hciserveradmin or hciupgradeutility at the command prompt on your UNIX machine and you will see the GUI windows.  

Hope this helps out people.  

It took me a day to get all this since Cloverleaf does not publish all this information, as these are site specific instructions.

These are just tips and tidbits I picked up from my colleagues and posted it here.

If you want to leave security enabled and not have to manually set your display, you can open a local xterm on your PC and ssh to the server using the “-X” or “-Y” options to ssh.  Currently I have to use “-Y”.  This automatically sets your display variable on the remote side in a way that causes the X11 communication to be tunneled through your SSH session.

I use Putty SSH with dynamic forwarding turned on and the Cygwin X-Server.

Using Cygwin Openssh is probably slightly more secure because it can read your xauth file, so you don’t have to disable authorization checking for localhost connections like you would with Putty.

Also, I like the “visual host keys” feature of Openssh.
