very slow using Java GUI

zhaojingqian — Tue, 18 Nov 2003 21:15:09 GMT

With my hp server ,I use to make an export DISLAY using xwin32 for a Motif application and
the performance was good.

I am now trying to run Java application(oracle installer) using xwin32, and the performance
are awful. I did already optimize the xwin32 conf, but it is still very
slow.

Did someone already meet this problem ? Why Java decrease the performance
?
Any solution, fix ???

It's just java. As far as I'm concerned, Java sucks and should be done away with!

I'm with Patrick on the java thing.

Add this to /etc/profile or the user .profile top deal with the DISPLAY issue.

DISPLAY=$(who -m -u | awk '{print $8}'):0.0
export DISPLAY

The oracle installer is slow, but not horrible, I just used it. What product are you installing? Are you sure your HP boxes network speeds are correct?

Might be a good idea to check.

lanscan

Take the number portion of the lan0 and use it in this command lan0 is 0

lanadmin -x 1

If you don't have the speeds you expect, look at hard coding network configuration in /etc/rc.config.d/hpbtlanconf

If the NIC is 100 BT or slower the switch settings must be manual on the switch port, especially for CISCO switches.

It depends!

Oracle database application installation is resource consuming and it depends on the congfiguration of the machine.

If your machine is running with very low memory and this would be the scenario.

Revert with the machine configuration.

you cannot compare this to a normal Motif application

It really depends on your network (intranet connenctivity ) etc., Oracle these days is coming up with installing patches with shell scripts which otherwise would use runInstaller. Iam not sure which Oracle product you are trying to install. I suggest you check if you can install the product or patch without runInstaller, if the option/script is provided with the product/patch you are trying to install.

Thank you,
