java apps going real slow

[Rick Garland]

Hi all:

Been using the Veritas Netbackup 4.5 on rp7410 running HPUX 11.11. System has 2 CPUs (875 MHz) and 8GB memory.

The Veritas app is java based and runs PAINFULLY slow. Have been in contact with Veritas tech support but they have been unable to come up with anything.

What I have verified, The HP is running at 1000MBits FD, I am running at 100FD. The switch port is locked at 100FD. I have modified the jnbSa.conf file to have INITIAL_MEMORY=96M and MAX_MEMORY=1296M - no luck. (Did this in 1 other file as well.)

Are there some kernel parms that need looking at as well?

Many thanks!

NOTE: This slowness is only with Veritas, all other java apps run fine.

To give justice to Veritas, have you tried running the GUI locally? You can do so by establishing a VNC Session, connect to that VNC session and launch jnbSA.

We NEVER run jnbSA as an X Application -- accross a network. We always run it locally .. either via a VNC Session OR if the server has its own Graphics Console & Keyboard...

If it still is slow, check with Veritas what Kernel Params you need to tune or better yet, check your Java version...

HTH.

Got the VNC loaded on HPUX 11.11 and fired up.
Connected to the vncserver running on the HPUX. The java is running MUCH faster. OK, it is not a Veritas problem, but what welse could it be? I have checked and verified net connections (1000FD on HPUX, 100FD on Linux)
and the switch (locked in - noauto) but still no joy.

Any other ideas? Please?

Thanks

(will assign points after I get more responses, if no more responses then you get them all)

Unfortunately, it is JAVA.. JAVA GUI's if not well written are just so slow if run accross a network and on top of X-Windows.

The big vendors know this and poor us need only look at VNC as the current fix.

Many thanks for your feedback. I suspected JAVA but was hoping otherwise.

Many thanks for the idea of running the VNC for the JAVA apps.

And Java is a hog...

Did I tell you that because of Java.. my Superdome n-Par is projected to be a 128GB system?

Java.. a hog.

But then is still universally good if done right, if architected right and yout VM (virtual machine) is good.

Got that right - HOG!
I'm not talking Harley's here either.

(An ElectroGlide would be nice)

Cheers,
Jeff (Who's found the Veritas vea util slow even when run locally. I don't think Java is their forte frankly.)

Jeffy,

A good one on how JAVA as an acronym should be interpreted!

Ha ha ha!
