X-Windows responded very poorly

[subrata Sur]

We have application which is using exceed to open the gui . It has been obseved that it is too slow to open up . When we check the application on the test server it is ok . So can u tell me what i have to check for this .
Seems the issue is for networks or the unix processes (HP-UX B.10.20 A 9000/800)

You could check the speed and duplex settings of your network interface. Ask your network specialist to check the settings on the switch.

Hope this helps,

Hello,

1. Check if the command "hostname" return the same name that is present in /etc/hosts.

2. Check if there is multiple lines for your hostname in /etc/hosts.

3. Check if in /etc/nsswitch.conf the line hosts is like this:

hosts files dns

I hope this could help...

And look if eventually you don't have any filesystem full...

$ hostname
suboz031
$ more /etc/nsswitch.conf

hosts: files[NOTFOUND=continue UNAVAIL=continue] dns [NOTFOUND=return UNAVAIL=re
turn TRYAGAIN=return] nis


The file system is ok

90% of the Exceed issues I've ever seen have been related to DNS resolution. Be it a duff DNS server or multiple IP addresses for the X-Client.

If you do an nslookup from the client and the server of the client your running the X Applcation on do you get the same result and more importantly do you get it without delay?

can u plz tell me How can i check this . We have multiple x-client on this server .

DNS problems will kill Xwindow performance. To determine that this is the case, on the HP-UX system, change the hosts: line to match Subrata's suggestion. This puts DNS second in line to resolve hosts and addresses. Now edit /etc/hosts and put in the IP address of your PC running Exceed. Now typically, PCs run with DHCP addresses so you'll have to constantly add new addresses as they are assigned. If you know the range of addresses used by the DHCP server, you can put all of them in your hosts file. The hostnames are unimportant, just assign sequential names.

If performance improves, you need to have your DNS admins add all of the addresses in the DHCP pool to the DNS servers.

Another possibility is LAN problems on your production machine. Run lanadmin and display the network stats. Problems with duplex mismatch will create FCS and framing errors as well as collisions (which are not possible on a full-duplex connection).

In /etc/hosts did you have only one line with suboz031?
if this is the case try to add suboz031.yourdomain.com at the end of this line:

XX.XX.XX.XX suboz031 suboz031.yourdomain.com

and in your /etc/nsswitch.conf try to comment "hosts" line and replace it by:

hosts: files

just to see if it's a problem of resolver...
