when launching EBSR12.1 setup, when it is starting I am getting the warning RW50004; Error code received while running external process. please find attached the log.
Check your log file yourself.
You dont have necessary directory permissions, disk space etc.
Check the log file and search the keyword "RW-"
Then go to oracle support if you cant understand the error message (but the messages are very clear)
Next time, do this approach, dont ask here. As, i believe, it is not helping to analyze the log file and check oracle support for you/instead of you. You have to do these kind of things yourself.
