Background Media Recovery terminated with error 448

User_2DM9RMar 3 2016 — edited Mar 10 2016

Hi,all

     I am trying to do the oracle backup&restore using dataguard.

     I installed 4 instances in a same server, and did the configuration correctly in every instance.

     but after i did the role switch-over for one instance, the MRP terminated by system, and after awhile,  the system attempt to start background MRP again, and it will be terminated again....

     the log information is showed as follows, and attachment is the configuration and inoc_pr00_43079.trc.

     hope you guys can help me, thanks very much....
