Quickly creating a Standby Database in 19c

A quick overview

1.  Create the parameter file initSTDBYDB.ora with additional parameters
  change or add DB_UNIQUE_NAME to be STDBYDB
  change the location of control files
  add fal_server to be the lookup name for the Primary (e.g. ORCLCDB)
  add log_archive_dest_2 to specify the Primary Service and DB_UNIQUE_NAME (note : If you are using "log_archive_dest", you can't use "log_archive_dest_2" to co-exist.  A default DB_RECOVERY_FILE_DEST location is preferable)
  add db_file_name_convert and log_file_name_convert to map file names to new directories (if they are to be different or, for example, if creating the Standby on the same server !!)  --- ensure that you have the new directories (or ASM DiskGroups) available on the Standby with the right permissions (including directories for PDBs and the PDBSEED) !
  change any other hardcoded directory names (e.g. for adump)

2.  Create a listener.ora and/or a new listener with a static SID_NAME entry for the Standby DB

3.  Add an entry for the Standby  in the Primary tnsnames.ora and for the Primary in the Standby tnsnames.ora

4.  Add at least one Standby Redo Log file to the Primary Database

5.  Ensure that you have the password for the SYS account (or will you be using SYSDG ?) on the Primary and copy the Password file to the Stadnby

6.  Start the Standby listener

7.  STARTUP NOMOUNT the Standby Instance (remember to have the ORACLE_SID set !!)

8.  Start rman on the Primary with :

rman target sys/manager auxiliary sys/manager@STDBYDB

and then issue the command

duplicate target database for standby from active database dorecover;

and thus the execution will be as :

oracle19c>rman target sys/manager auxiliary sys/manager@STDBYDB

Note :  For simplicity, I didn't use the SPFILE specification in the DUPLICATE command to create and update an SPFILE at the Standby.  I am using a simple initSTDBYDB.ora pfile


In the next blog post, I will be covering how to begin (and then monitor) shipping of redo from the Primary to the Standby.
