Load Balancing

Load Balancing : Basic ideology implementing a Load Balancer is to balance the load on the servers by routing the incoming requests accordingly.

1) Hard Ware Load balancing
2) DNS Load Balancing ( round robin fashion )

U can confirm by doing

dig publicname.domainname.com

or

nslookup publicname.domainname.com

Also to confirm tht DNS is routing requests properly

do

telnet publicname.domainname.com

- It will show hostname1

again if u do

telnet publicname.domainname.com

- It should show hostname2


- XML variables involved

s_webentryurlprotocol
s_webentryhost
s_webentrydomain
s_active_webport
s_login_page
s_external_url


UR's Key Run ;-) 

Register concurrent program with request group.

Most of us came across a situation where
after defining(promoting) a concurrent program ,to make other users be able to
run the program we need to add the program to a request group(which we used to
do by navigation through security->responsibility->Request).
The same can be achieved by running package FND_PROGRAM as foloows.

DECLARE
BEGIN
FND_PROGRAM.add_to_group
(
PROGRAM_SHORT_NAME =>'XX_XXXXXX'
,PROGRAM_APPLICATION =>'AR'
,REQUEST_GROUP =>'Receivables All'
,GROUP_APPLICATION =>'AR'
) ;
commit;
exception
when others then
dbms_output.put_line('Object already exists');
END ;
