hi all,
I had been upgrade from jde 8.12 to jde e1 9.10 using tool release 9.1.5.7, Oracle 12c ( 12.0.1.2), weblogic 12c (12.1.3) and weblogic 12c ( 12.1.2 ) and jdk using 1.7.0_25 all under windows 2012 R2 and vmware. only database server I using one box ( no vmware ).

when I browsing using IE 11 login for web client is need 25 - 30 seconds ( for firsttime, seconds, etc ).

how to troubleshooting for this case ?

Hi Iwan

A couple of things to try. First of all, make sure that your JVM is configured correctly. In the weblogic startup, I would ensure that -Xms and -Xmx are set to the same value - at least 2048Mb. You want at least 32Mb per concurrent user session.

Secondly, ensure that the JDK you're using is the 64Bit JDK.

Thirdly - try modifying the /jdk/jre/lib/security/java.security file -
modify the line :
securerandom.source=file:/dev/urandom
to be
securerandom.source=file:/dev/./urandom

That often helps to really speed up the JDK. Its a known, documented issue.

Next - try a different browser/workstation ! Maybe the time is actually being wasted locally through local applications ? Try running Chrome and trying to see if its any faster.

Lastly - to identify any performance issue, make sure you take a close look at your VM when it starts the Weblogic server. Is it using excessive CPU after starting weblogic and prior to a user logging in ? Is there substantial memory or disk utilization ? Lastly - is the VM as close as possible on the network to the Enterprise Server ? These items will certainly help.

I have an amazon AWS instance running on windows, and the time it takes for my mac with Chrome to log into E1 is around 6 seconds (and I have logged in several times before). Most of that time is likely internet latency. I feel thats pretty darn fast. After login to opening P4210 takes ~ 2 seconds. Thats definitely the kind of performance you need to be able to get out of your system.
