Weblogic 10.3.2 Error when deploying ear file

Question

Using WLS 10.3.2, wwhen activating changes, I obtain following errors:
An error occurred during activation of changes, please see the log for details.
Exception occured while downloading files
[DeploymentService:290066]Error occurred while downloading files from admin server for deployment request "1,285,335,764,675". Underlying error is: "[DeploymentService:290065]Deployment service servlet encountered an Exception while handling the deployment datatransfer message for request id "1,285,335,764,675" from server "p8aerm". Exception is: "Could not create temp location for application : Engine-wl"."
Would someone with expertise confirm where "temp location for application" is on an AIX 6.1 server.
Any help appreciated.

Answer 1

What user runs your weblogic? the oracle user?
In my case weblogic is started by a weblogic user who owns all the WLS folders.
Try $> ps -fea | grep p8ce to verify the user running the weblogic instance.
In a RH5 the privileges are (755):
4 drwxr-xr-x 2 weblogic weblogic 4096 Nov 19 2009 .internal
4 drwxr-xr-x 5 weblogic weblogic 4096 Nov 19 2009 WLinternal
4 drwxr-xr-x 8 weblogic weblogic 4096 Nov 23 2009 ..
4 -rw-r--r-- 1 weblogic weblogic 379 Sep 20 16:53 WebServiceUtils.ser
0 -rw-r--r-- 1 weblogic weblogic 0 Sep 20 16:55 SysAdmServer.lok
4 drwxr-xr-x 5 weblogic weblogic 4096 Sep 21 19:28 .
4 drwxr-xr-x 6 weblogic weblogic 4096 Sep 21 19:28 WLuser
The folder WLuser will be created when the deploy starts.
In your case an error happends before this step.
