Load Balancing of App & Process scheduler server

APP SERVER LOAD BALANCING:

1.       We have to enable load balancing when more than 10 psappsrv process are started.

2.       If we select large template then only more than 10 process are started.

3.       If we enable LB then first it will look for the ideal queue then it calculate the load of each & every queue.

4.       In App server domain we enable load balancing option in psappsrv.ubx

I,e c:\pshome\appserv\DN\psappsrv.ubx   --àLDBAL=Y

5.       Open webserver configuration file I,e configuration.properties. In this we will provide a list  of App server domains in the format of

Psserver=Appservername1:JSLPORTNO,Appservername2:JSLPORTNO

PROCESS SCHEDULER LOAD BALANCING:

1.       We can enable in this file:

C:\pshome\Appserv\psprcs\DN\psprcs.ubx

LDBAL=Y

2.       Creating multiple processes schedulers (Enable LB b/w multiple process scheduler)

Logon to PIA->People Tools->Process Scheduler->servers->search (click on add new value tab)

Server Name= PSNT

If First serve is down (I,e PSNT) it will automatically process to the second server(I,e PSNT1)

TUNNING:

Psappsrv.cfg

Jolt Listener

Port=9000

Min Handlers=5                               (one handler will occupy 5 MB of RAM)

Max Handlers=7                            NOTE: configure listener.ora & tnsnames.ora by using netca command.

Max clients per Handler=40
