WCC reloading login screen

[Jose Lopez]

Hi,

We have a 11.4 SP6 WCC running in RHEL 6.10.

Sometimes when a user wants to log on WCC though he enters his ID and password properly, Dashboard screen is not loaded by login screen is loaded again and he is asked to enter again his ID/password.

I haven seen this behaviour in all main browsers (IE, Firefox and Chrome)

Following lines can be seen in WCC log

# Creating EEM session. ID=948C352BFBB02E0A3F762E08AD5E0630CA7D8E291E653E4BA5F881E445A40370.emidvwcc0001|USER=hppzybyt

it looks like if WCC were destroying an old session and creating a new one.

Is there any way to fix it?
thanks

Hi,

Is there a message on the logon screen like EEM is down or invalid userid/password.

Regards,
Mike

​Hi Mike,

thanks for your answer. I should have updated this post as we found out it was a IE issue.

We have a load balancer and after that 2 WCCs.
It seems that for some reason IE is spreading the authentication BETWEEN both WCC servers so the authentication process fails.
If we shutdown one of the WCC as test, IE works fine but we lose high availability

Best regards.
José

The load balancer should be set to maintain a sticky or persistent connection for each logged on user.  WCC creates a session id that is passed on subsequent calls and that id is only valid on that WCC.  That could be the problem.

Mike
