set nddconf file

[Fauziah Mahdan]

Hi all,
How to set this value in HPUX 11.23 isntalled with Websphere app 6.0.2.17

a.. Java virtual machine (JVM) virtual page size

1. Description: Sets the JVM instruction and data page sizes to 64 MB to improve performance.

2. How to view or set: Use the chatr +pi64M +pd64M /opt/WebSphere/AppServer/java/bin/PA_RISC2.0/native_threads/java command. The command output provides the current operating system characteristics of the process executable.

3. Default value: 4 MB, if not assigned

4. Recommended value: 64 MB


b. TCP_KEEPALIVE_KILL

1. Description: Determines the maximum number of times to probe before dropping.

2. How to view or set: Use the ndd command to determine the current value or to set the value. For example:

ndd -set /dev/tcp tcp_keepalive_kill 5000
3. Default value: None

4. Recommended value: 5000 milliseconds

also tos et it permanently in /etc/rc.config.d/nddconf.
Thanks

For changes in ndd conf see last available index and write an entry like this one:

TRANSPORT_NAME[0]=tcp
NDD_NAME[0]=tcp tcp_keepalive_kill
NDD_VALUE[0]=5000

OK if I want to add the nddconf for ip_send_source_quench what is the value inside the [x]

TRANSPORT_NAME[x]=ip
NDD_NAME[x]=ip_send_source_quench
NDD_VALUE[x]=0

This is the index value. If your last one is 0 then the next one should be 1. They must be in sequential order. [1]

more /etc/rc.config.d/nddconf
and look the starting potion of it.

Regards.
