The Replicate After_Journal Configure command is an optional
command you can use to preconfigure the master and standby
databases, one database at a time.
NOTE
You cannot preconfigure both the master and standby database
attributes in a single Replicate After_Journal Configure
command. Moreover, you cannot enter the Replicate After_
Journal Configure command on the standby database to
preconfigure master database attributes, or preconfigure
standby database attributes from the master database.
You can specify one or more of the following qualifiers when you
enter the Replicate After_Journal Configure command on the master
database:
Master Database
Qualifiers
Alt_Remote_Node (1)
Checkpoint
Connect_Timeout
[No]Log
[No]Quiet_Point
Reset
Standby_Root (2)
Synchronization
Transport
Footnote (1): You must also specify the Standby_Root qualifier.
Footnote (2): You must specify the Standby_Root qualifier the
first time you configure the master database.
The master database attributes that you specify are stored in the
master database root file. (You cannot specify the Wait, NoWait,
and Output qualifiers on the Replicate After_Journal Configure
command. You can specify these qualifiers when you invoke the
Replicate After_Journal Start command.)
You can specify one or more of the following qualifiers when
you enter the Replicate After_Journal Configure command on the
standby database:
Standby Database
Qualifiers
Buffers
Checkpoint
Gap_Timeout
Governor
[No]Log
Master_Root (1)
[No]Online
Reset
Footnote (1): You must specify the Master_Root qualifier the
first time you configure the standby database.
The standby database attributes that you specify are stored in
the standby database root file. (You cannot specify the Wait,
NoWait, and Output qualifiers on the Replicate After_Journal
Configure command. You can specify these qualifiers when you
invoke the Replicate After_Journal Start command.)
You should use the Replicate After_Journal Configure command if
you want to:
o Preset qualifier values that you typically specify on the
Replicate After_Journal Start command, but without starting
replication operations.
The values you specify become the new default qualifier values
that are stored in the database root file.
o Be able to quickly start replication operations by invoking
a single Replicate After_Journal Start command on the master
database.
If you use the Replicate After_Journal Configure command
to preconfigure the master and standby databases, you can
start replication for both databases by entering one Replicate
After_Journal Start command on the master database.
For example, if you have preconfigured both the master and
standby databases and then invoke the Replicate After_Journal
Start command on the master database node, the Hot Standby
software:
1. Starts replication operations on the master database using
default qualifier values from the master database root file
2. Creates the network connection to the standby database
3. Attaches the master and standby databases to the network
4. Starts replication operations on the standby database using
default qualifier values in the standby database root file
5. Synchronizes committed transactions on the master and standby
databases
NOTE
If you have not preconfigured database attributes using
the Replicate After_Journal Configure command, the Hot
Standby software uses either the system-supplied defaults
or the values that you specified on a previous Replicate
After_Journal Start command.
