Error while starting the Weblogic Server in SOA Suite

Question

Hi All,
I installed SOA Suite 11.1.1.4.0 (weblogic server and SOA managaed server) couple of days back.The same machine has two more weblogic servers which contain different applications.(Means there total three Weblogic admin servers and one SOA manage server).
I used to start all the servers successfully .I also used to start SOA server successfully .
But today when I am trying to start Weblogic Admin server(SOA related),I am getting below error:
Error Log:
***C:\Oracle\Middleware\user_projects\domains\mdm_soadomain\bin>startWebLogic***
***The system cannot find the path specified.***
-------------------------- --------------------------- some error log content here -------------------------------------

***C:\Oracle\Middleware\user_projects\domains\mdm_soadomain\bin>***
I saw setDomainEnv.cmd file and all other files.I did not change anything recently.But I am nit getting any idea why that exception is coming.
PLease give me guidance for this.
Thanks in advance

Hi,
Is the message "The system cannot find the path specified." reported as a direct response on the "C:\Oracle\Middleware\user_projects\domains\mdm_soadomain\bin>startWebLogic" command, by Windows? Or do you see that this command really is executing but is the message reported later in the logs? Is it also reported on the command window output?
From your questioning I take it that the command initially really is executing and that the path not found message is reported later in the process. In that case it you should debug the start process. My method in these cases is adding recognizable echo statements in the weblogic start scripts. Firstly to see how far the process comes, which statements are executed. Basically to narrow down at what specific statement/command the scripts fails.
Secondly to echo the specific environment variables used. These things don't happen "magically" somehow, somewhere, something is changed. Although you might not find out when it was and who was responsible.
What might help is to know that the startWeblogic script is calling the setDomainEnv script in the same folder and also does a call to a weblogic settings script in the weblogic binaries folder from the weblogic home. (I don't know the scripts name by heart and I haven't have a VM started with a WLS env right now.
Then after these two scripts and doing some Environment variable checking to build up the arguments (java vendor, memory-args, etc.) for the java-process, it in the end calls the java-process from the choosen JVM-home. So it might be interesting to look up the place where it actually calls java. And right before that put echo's to display the JAVA_HOME and the complete java-command that it plans to execute. It might be that you installed another JVM/JDK, maybe you updated the default JVM on windows? And that it just can't find the correct JVM.
In setDomainEnv you can set up the paths to the different JVM's. Using the JAVA_VENDOR environment variable you can switch between them.
For instance, if you want to use JRockit, look voor the BEA_JAVA_HOME. The variable for Sun Hotspot should be around there as well. Validate those.
Hope this helps.
