Netweaver 7.5 Java AS Connection Refused error during installation.

[ashrafsharaf]

I am trying to install a 7.5 NW Java AS with an Oracle DB and i keep getting an error in the phase "deploying java components" where it says that connection to host <myhostname>:50004 has failed because the connection was refused. After doing some research i read it's related to the P4 port being closed/occupied but i couldn't find a way to change it or fix the problem.

The installation isn't yet complete and service doesn't start from the MMC, i tried adding the parameter to specify a p4 port in the default profile but i got the same error.

Is the database up and running? Is the Oracle database installed according to SAP recommendations?. Check all the trace files under E:\usr\sap\ESS\J00\work

DB is up and running however when i try to connect i get an adapter error unless i explicitly set an SID for the database(previously set one during the installation).

I am not sure what's causing this behavior.

What about the Listener? is it running? Again, check the logs in the above suggested location. Without logs there is nothing other can do. other than giving speculcative answers.

The only reason i didn't post the log is that i didn't have it, was attempting another install. Anyway you were right it was something with the DB. It was up and running but i couldn't access the java config tool for example as it gave me a db connection related error although i could connect as sysdba from the cmd.

What i did was uninstall the SAP AS, Deinstall DB, clear all SAP/Oracle related registry and windows file and reinstall oracle, and explicitly set an SID for the db with the set oraclesid command, then connecting as sysdba and shutting down then starting up the db. then i attempted another installation and it seems to have passed the phase that had the error.

Thanks a lot for the help.
