Email Server Java

[lekie]

Dear all,

    There are email_server_a is primary, email_server_b is backup and a webapi server. Has anyone know why in connection tab of webapi must to connect to both of email_server a and b? I have tested a case,If in connection tab of webapi its connect only email_server_a when email_server_a is fail and email_server_b is changed to be primary then I couldn't send email via web form?

Thanks you inadvance.
cheers,
Lekie

Hi Lekie,

I haven't tried such configuration but I think it's a conflict between supported HA modes. WebAPI server does support HA by using load-balancing mechanism. That means that it can load-balance between multiple applications of the same type that are connected to it (listed on Connection tab). Email Server Java itself support warm-standby HA. If you combine these two modes then it won't work as WebAPI doesn't care about ESJ warm-standby - it simply load-balances traffic between connected applications only. So when primary ESJ goes down WebAPI doesn't care about backup ESJ as WebAPI is not connected to this application.

You have to specify both in WebAPI Server connections, but it will use only "current" primary based on information from SCS and switch to another if switchover happened.
