[nv-l] [OVWDB] cache size

Allison,
I haven't looked at the manuals for v7 yet. But, are you saying that the manual is now advising to set the cache size at zero for automatic cache adjustment??? That surprises me!!! I know it was a cool feature up through aprox v4. At some release thereafter it didn't work.

My experience with setting it to zero was that once you exceeded an arbitrary number of objects in the object database it stopped auto-adjusting. I had a PMR opened for it a couple of years ago. The solution was to always hard code the cache size appropriately and do not use zero. This was truly an undocumented feature because that is exactly what they did. They removed the documentation regarding setting the cache size to zero from the Administrators Guide.

Now you say it is back. I hope it has been fixed!!!

How many nodes do you have?

You may want to check your cache sizes to make sure enough memory is
allocated for your instance of Netview. We just went through the same
process. The default for our Netview was 5000 objects. It took us 4 and
1/2 mintues for Netview to complete its "Map Synchronization" process during
startup. We determined the DB had over 6000 objects (using the OV
commands). We performed many cleanup processes from /usr/OV/bin and changed
the DM cache size to 0 (0 will let Netview determine dynamically the size it
wants to use). After changing the cache size, the time went from 4.5
minutes to 45 seconds. If "May Syncronization" slowness is you problem like
it was ours, you will see "Synchronizing" on the bottom left of the TME10
display. While this is happening during startup, the TME10 display is
basically non-responsive.

FYI, all of this is documented in the Netview Manuals.

Best of luck,

Subject: [nv-l] Netview 7.1.1 Web Interface

Have installed Netview for first time ever on an AIX box. Looks like the
Web interface is working ok, but it is very slow coming up. We were
considering using the Web interface for the NOC station, but we can't live
with how slow it takes to come up. Is there additional configuration that I
don't know about that needs to be done?

When I had Netview 7.1 on an NT Server, it came up quickly. Any ideas?

Thanks,
