As
you can see from Don's environment, the more X-clients there are, the more
memory is required - take a look at the ipmap and ovw_binary processes. Each
ovw is also going to start a maptreeserver process which accounts for the java
processes that Don also has consuming memory.
If there is no intent to use Java Clients, the NetView
Server can be configured not to launch the individual java (jre) processes per
ovw session. Also the nvevents process that goes along with each ovw process
can start to have an impact on CPU usage which is especially important if you
don't have multiple CPUs.
If Java
Clients are used instead of X-clients, you will probably find less memory is
used on the actual NetView Server, especially with an increase in the the
number of operators simultaneously connecting.

Considerations for AIX NetView Server Installat ion

Ray,
Here's a screen shot from "nmon" of my
NetView server.
AIX 5.2
NetView
7.0.3
objects in ovwdb : 13,334
ovwdb cache : 35,000
trapd cache :
50,000
Installed RAM : 3G
Swap : 2.2G
Paging Space used never drops below
20%
I am running dangerously near capacity with
3G of RAM and 2.2G of swap.
With 2.0G of paging space I
occasionally was thrashing. I bumped it up to 2.2G.
I am not using any Java clients. Still using X11/Motif via
eXceed.
I have requested more RAM....
RAM, is like many other things...... You can't have too much
:)

Subject: [nv-l] Memory Considerations for AIX NetView
Server
Installation
Hello Everyone.
NV 7.1.3 on AIX 4.3.3. ML10.
I was doing research on memory
considerations. I'm sure I need to buy more
memory for my server
but I don't know how much.
In the section entitled "Computing
Memory Needs based on Object Count", I
noticed the numbers in
the Config. Guide have not changed from 6.0 to 7.1.x.
And I'm aware of the java processes to consider as stated in the
Release
Notes. My ovwdb cache setting is 35,000.
According to the ovobjprint -S
output, the number of objects
defined in the database is 23,500.
Here's a list of processes for a
typical NetView (native console) user and
vsz of each.
user 18028
/usr/OV/jre/bin/java -jar /usr/OV/jars/virtualdesktop.jar
--logconfig
/usr/OV/conf/virtualdesktop-log4j.properties
38408
user 24826
/usr/OV/bin/ipmap
92724
user 38346
/usr/OV/bin/nvevents
4872
user 44964
/usr/OV/bin/collmap
764
user 51694
/usr/OV/bin/dispsub
504
user 59556
rshd
576
user 59940
/usr/OV/bin/backup
772
user 60886
/usr/OV/jre/bin/java -jar /usr/OV/jars/maptreeserver.jar
--logconfig /usr/OV/conf/maptreeserver-log4j.properties
22792
user 66246
/usr/OV/bin/disptec
316
user 89140
ksh /usr/bin/netview
412
user 90408
/usr/OV/bin/ovw
60800
user 93550
/usr/OV/bin/ovhelp
552
I used ps -ef -o user,pid,args,vsz |
awk '/user/ && !/awk/' to get the list.
I used ps-ef -o user,pid,args,vsz | awk
'/user/ && !/awk/ {sum +=
$NF}END{print sum}' to get the
totals.
The total is 223,492K. The ovw process
alone is 60,000K.
Here are my questions:
Are my methods for arriving at these numbers valid?
Should these values in the Config. Guide be updated?
Do these values from my process list seem correct?
How do they compare with other AIX NetView Server installations?
Thanks.
