Hi guys,

I need help. So we have the below landscape. We have 2 BOBJ systems. Currently, only SI1 is connected to the 2 web dispatchers. We need to connect both BOBJ systems. Now, how will the load balancer know which BOBJ system to connect? We are thinking the below parameter value set in Web dispatchers.

SID=SI1, EXTSRV=https://hostnamesi1.com:8443, SSL_ENCRYPT=2, SRCURL=/BOE/, SRCSRV=*:44380
SID=SI2, EXTSRV=https://hostnamesi2.com:8443, SSL_ENCRYPT=2, SRCURL=/BOE/, SRCSRV=*:44385

Hi!

Using a different port for each BOBJ system is one option.

You can also use virtual hostnames (SRCVHOST).

This Expert Content page has information on the selection criteria available in the Web Dispatcher.

@Isaias - but the load balancer URL which end users are using is fixed. They enter to port 443.

Well...

the external load balancer needs a way to differentiate between the two systems, so it can send the request to the corresponding port on the Web Dispatcher...

Either you add one more port and users from one BOBJ system need to adjust their favorites... or maybe you can use virtual hostnames.

You should discuss available options with your load balancer team 😉
