Also, have you checked your alert log for errors and looked at

 select * from V$DATAGUARD_STATUS order by TIMESTAMP;

Question, Do you have standby logfiles configured? If not then real time apply cannot function since it's waiting for the EOF marker on the current logfile.

we have a database original on ORACLE 10.2.0.4 and we upgrade it to 11.1.0.7. after that we create standby database and tried to use "real time apply" feature.

Primary database can transfer log files to standby database and standby database also can apply logs. The problem is it can NOT work on "real time apply".

Ant ideal what wrong?
