Oracle 19c – RMAN recover from service feature at work

It’s not something new in 19c, however, this feature has been improved and covers all the steps that a DBA must do or was supposed to do in the past in order to recover a lagging standby. I will simulate it and this is my setup:

I have created a dataguard environment using Vagrant.

The primary was created using the following:

dbca -silent -createDatabase                                                 \
  -templateName General_Purpose.dbc                                          \
  -sid ${ORACLE_SID}                                                         \
  -responseFile NO_VALUE                                                     \
  -gdbname ${DB_NAME}${DB_DOMAIN_STR}                                        \
  -characterSet AL32UTF8                                                     \
  -sysPassword ${SYS_PASSWORD}                                               \
  -systemPassword ${SYS_PASSWORD}                                            \
  -createAsContainerDatabase false                                            \
  -numberOfPDBs 1                                                            \
  -pdbName ${PDB_NAME}                                                       \
  -pdbAdminPassword ${PDB_PASSWORD}                                          \
  -databaseType MULTIPURPOSE                                                 \
  -automaticMemoryManagement false                                           \
  -totalMemory 2048                                                          \
  -storageType FS                                                            \
  -datafileDestination ${DATA_DIR}                            \
  -redoLogFileSize 50                                                        \
  -emConfiguration NONE                                                      \
  -initparams db_name=${DB_NAME},db_unique_name=${NODE1_DB_UNIQUE_NAME}      \
  -ignorePreReqs

And the standbys were created using the DUPLICATE command:

DUPLICATE TARGET DATABASE
  FOR STANDBY
  FROM ACTIVE DATABASE
  DORECOVER
  SPFILE
    SET db_unique_name '${NODE2_DB_UNIQUE_NAME}'
    SET audit_file_dest '/u01/app/oracle/admin/${NODE2_DB_UNIQUE_NAME^^}/adump'
    SET control_files '/u01/oradata/${NODE2_DB_UNIQUE_NAME^^}/control01.ctl','/u01/oradata/${NODE2_DB_UNIQUE_NAME^^}/control02.ctl'
    SET standby_file_management 'AUTO'
    SET log_file_name_convert '/u01/oradata/${NODE1_DB_UNIQUE_NAME^^}','/u01/oradata/${NODE2_DB_UNIQUE_NAME^^}'
    SET db_file_name_convert '/u01/oradata/${NODE1_DB_UNIQUE_NAME^^}','/u01/oradata/${NODE2_DB_UNIQUE_NAME^^}'
    SET db_recovery_file_dest_size '20G'
    SET db_recovery_file_dest '/u01/app/oracle'
    SET dg_broker_start 'FALSE'
  NOFILENAMECHECK; 


----------------------------------------------------------------------------------------------


DUPLICATE TARGET DATABASE
  FOR STANDBY
  FROM ACTIVE DATABASE
  DORECOVER
  SPFILE
    SET db_unique_name '${NODE3_DB_UNIQUE_NAME}'
    SET audit_file_dest '/u01/app/oracle/admin/${NODE3_DB_UNIQUE_NAME^^}/adump'
    SET control_files '/u01/oradata/${NODE3_DB_UNIQUE_NAME^^}/control01.ctl','/u01/oradata/${NODE3_DB_UNIQUE_NAME^^}/control02.ctl'
    SET standby_file_management 'AUTO'
    SET log_file_name_convert '/u01/oradata/${NODE1_DB_UNIQUE_NAME^^}','/u01/oradata/${NODE3_DB_UNIQUE_NAME^^}'
    SET db_file_name_convert '/u01/oradata/${NODE1_DB_UNIQUE_NAME^^}','/u01/oradata/${NODE3_DB_UNIQUE_NAME^^}'
    SET db_recovery_file_dest_size '20G'
    SET db_recovery_file_dest '/u01/app/oracle'
    SET dg_broker_start 'FALSE'
  NOFILENAMECHECK;

And the broker config was created using the following:

CREATE CONFIGURATION my_dg_config AS PRIMARY DATABASE IS ${NODE1_DB_UNIQUE_NAME} CONNECT IDENTIFIER IS ${NODE1_DB_UNIQUE_NAME}${DB_DOMAIN_STR};
ADD DATABASE ${NODE2_DB_UNIQUE_NAME} AS CONNECT IDENTIFIER IS ${NODE2_DB_UNIQUE_NAME}${DB_DOMAIN_STR} MAINTAINED AS PHYSICAL;
ADD DATABASE ${NODE3_DB_UNIQUE_NAME} AS CONNECT IDENTIFIER IS ${NODE3_DB_UNIQUE_NAME}${DB_DOMAIN_STR} MAINTAINED AS PHYSICAL;
ENABLE CONFIGURATION;
SHOW CONFIGURATION;
SHOW DATABASE ${NODE1_DB_UNIQUE_NAME};
SHOW DATABASE ${NODE2_DB_UNIQUE_NAME};
SHOW DATABASE ${NODE3_DB_UNIQUE_NAME};

Now I have the following configuration:

Configuration - my_dg_config

  Protection Mode: MaxPerformance
  Members:
  orcl_dga - Primary database
    orcl_dgb - Physical standby database
    orcl_dgc - Physical standby database

Fast-Start Failover:  Disabled

Configuration Status:
SUCCESS   (status updated 49 seconds ago)

Now let’s disable the transport of the archivelogs from PRIMARY (orcl_dga) to the standbys

DGMGRL> edit database orcl_dga set state=transport-off;
Succeeded.
DGMGRL>

Let’s switch couple of times the archivelogs:

DGMGRL> sql 'alter system switch logfile';
Succeeded.
DGMGRL> /
Succeeded.
DGMGRL> /
Succeeded.
DGMGRL>

Let’s delete the archivelogs on PRIMARY:

RMAN>  delete force noprompt archivelog all;

Let’s see what’s the situation on the standbys:

Both databases are complaining about missing archivelogs.

Let’s recover the ORCL_DGB database. For this we are going to use RMAN

[oracle@ol8-19-dg2 ~]$ rman target /

To fix this, we need to disable the recovery on the standby databases:

DGMGRL> edit database orcl_dgb set state=apply-off;
Succeeded.
DGMGRL>  edit database orcl_dgc set state=apply-off;
Succeeded.

Let’s try again to recover it:
