hello

i have a problem with introspection: i want to introspect wls.
i installed wls on a virtual machine. zip archive, no installer.
i also installed ovab on my local virtual machine.

start ovab, conect to serverpool: ok. now i want to start a introspection. but i got only an error:

INTROSPECTION STARTED for: juriwls

ok may the interfaces are down: checked, ok. static ip

    Hi,

    The output above could be indicative that we could SSH to the remote side but not connect via the ports because of the forwarding. Can you make sure SSH port forwarding is enabled? Oracle Virtual Assembly Builder requires that SSH port forwarding be enabled on reference systems in order for remote operations (such as introspection and packaging) to work properly.

    Thanks

    INTROSPECTION DONE for: juri
    Introspection failed
    Error: OAB-50002: Failed to create assembly for WLS domain.
    Caused by: OAB-50042: Domain template creation failed.
    Action: Check /tmp/abRemote_oracle/ab_home/tmp/createDomainTemplate18246.out and /tmp/abRemote_oracle/ab_home/tmp/createDomainTemplate18247.log for details. These log files will be on the remote system if this is a remote introspection. This problem must be resolved before introspection can succeed.


    ok lets check these log files: cat on these logs.
    these logs are EMPTY!!!

    i dont know what to do now ...

    I guess we will need to collect some more data to figure out what might be causing the failure. Can you try these:

    1. Look at /tmp/abRemote_oracle/ab_home/logs/assemblybuilder.log to see what kind of error is reported in there.

    2. Try creating WLS domain template manually by yourself (using WLS pack.sh utility that is probably under $MW_HOME/wlserver_10.3/common/bin directory). I am surprised the two domain template log files (under /tmp/abRemote_oracle/ab_home/tmp directory) are empty, could it be some permission issue. Hopefully trying to manually create WLS domain template jar will expose those issue, if any.

    3. Try doing local introspection instead of remote. I mean install OVAB on the same machine as WLS and do local introspection. It would help us narrow down the offending area.

    Thanks
