jre processes are started for snmpserver, webserver, and netviewd. So de-registering or not starting them as you have done with the OVs_NO_START will stop jre processes for these guys.
Launching native X-based NetView GUIs (the ovw_binary, ipmap combination) also start jre processes. I think it is two per GUI. To prevent the jre processes from starting, remove the registration files "maptreeserver.reg" and "virtualdesktop" from the "/usr/OV/registration/C/" directory. You must remove them from this directory - you cannot simply rename them. ovw will read every file in that directory regardless of its name.
If you have a look at the maptreeserver.reg file, you will see the command used to start the jre process for maptreeserver.
This should account for all the jre processes that belong to NetView with the exception of any Java based tools you launch such as the netmon seedfile editor etc.
I hope this helps you save on memory usage :-)

Gareth,
Where is the option configured to prevent starting the java processes per ovw session. I have looked in applsetup and netview.pre.
I also looked for "java" in the Admin guide and the config guide with no success.
I have also modified webserver.lrf and snmpserver.lrf to OVs_NO_START and stopped and re-registered daemons with ovdelobj/ovaddobj.
I will probably use these at a future date, but not right now.
Thanks,
Don Davis

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.

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.
