Duplicate replication database in Oracle 10g

This experiment uses the duplicate command to create a copy database in the local environment. The target database is hongye, And the copied database is catdb.

Environment alias settings:
Alias SQL = 'maid sqlplus/nolog'
Alias rman = 'rlwrap rman'
Alias dbs = 'CD $ Oracle_HOME/dbs'
Alias rdb = 'CD $ ORACLE_HOME/rdbms/admin'
Alias udu = 'CD $ ORACLE_BASE/admin/$ ORACLE_SID/udump'
Alias bdu = 'CD $ ORACLE_BASE/admin/$ ORACLE_SID/bdump'
Alias rmalert = 'rm-f $ ORACLE_BASE/admin/$ ORACLE_SID/bdump/*; rm-f $ ORACLE_BASE/admin/$ ORACLE_SID/udump /*'

The detailed steps are as follows:

1. Construct the catdb initialization parameter file. The parameter file used in this experiment was created from the hongye database and made some modifications.
Note that the parameters db_file_name_convert and log_file_name_convert control the renaming of data files and log files. You can also use the set newname command to rename data files, the log file rename can be specified in the duplicate command clause, but it is not easy to convert the init parameter.
The db_file_name_convert and log_file_name_convert parameters are all renamed using string replacement. By replacing the specified string of the target file name with the specified string, a new file name is generated.
In this experiment, the data file of the hongye database is stored in the path:/oracle/oradata/hongye/, and the data file path of the catdb is/oracle/oradata/catdb /, therefore, you only need to replace hongye in all file names with catdb.
