Topic: Problem at cloning of a DB with the help rman duplicate
Recently I faced a problem unusual to me at DB cloning. I launched DB cloning approximately following command:
duplicate target database to newdb spfile parameter_value_convert ' olddb ', ' newdb' set db_recovery_file_dest_size = ' 1g' set db_recovery_file_dest ='somedg1' set control_files ='somedg1 ', ' somedg1' set db_create_online_log_dest_1 ='somedg1' set db_create_file_dest ='somedg1' set pga_aggregate_target = ' 1g' ;
In the course of cloning I noted unusual messages from rman:
datafile 11 not processed because file is offline datafile 12 not processed because file belongs to tablespace with one or more offline immediate datafile (tablespace1)
Further in a script generated rman':
skip forever tablespace "tablespace1";
And in the end, indifferently, rman opened without one tabular space.
In process it has been installed that this day in this tabular space the new file has been added and between the moment of adding of a file and recovery time has not been made any backup copies except archive logs.
There were two questions:
1) whether Normal this behavior rman'? Or there can be it a bug. on a metalink found nothing.
2) whether It is possible what to redefine that in the image this behavior? For example me arranged more if rman simply quitted with an error that cannot create a file. I do not say already that rman could create quite this file using available information.
1) Rman at performance duplicate it is connected to target, auxiliary and catalog.
2) the Version of a DB 184.108.40.206 PSU 170718
3) As storage both on a source and on the receiver it is used ASM
4) I realize that it was possible to make a differential backup copy after adding of files, but this variant not absolutely approaches me for some reasons.
5) In a DB-source there is no file or tabular space in the status "OFFLINE"
I will be very grateful if you offer the variants of the possible reasons and the decision of this problem.
If the given information has not enough, I will try to add it operatively.
