It is advisable to review the relevant log files after any patching operation. The adop log files are located on the non-editioned file system (fs_ne), under:

s_ne_base/EBSapps/log/adop/<adop_session_id>/<phase>_<date>_<time>/<context_name>/log

For example, if s_ne_base was /u01/R122_EBS/fs_ne, the session ID was 15, and the <CONTEXT_NAME> was patch01_testsys, the path to the adop log files from 9th June 2013 would resemble this:

/u01/R122_EBS/fs_ne/EBSapps/log/adop/15/apply_20130609_112226/patch01_testsys/log
