Some of the qualifiers for the Replicate After_Journal Start
command are applicable only when you start replication operations
on the master database node, while others are applicable only to
the standby database node. The following table categorizes the
qualifiers according to usage:
Table 26 Qualifier Usage for the Replicate After_Journal Start
Command
Master Node Master and
Qualifiers Standby Nodes Standby Node Qualifiers
Alt_Remote_Node Checkpoint Buffers
Connect_Timeout [No]Log Gap_Timeout
[No]Quiet_Point [No]Wait Governor
Standby_Root Output Master_Root
Synchronization [No]Online
Transport
The Hot Standby software does not allow you to use qualifiers
that are not valid for the database where you enter the command.
Therefore, when you enter the Replicate After_Journal Start
command on the:
o Master node - you can specify any of the qualifiers listed in
the first and second columns of above table
o Standby node-you can specify any of the qualifiers listed in
the last two columns of the above table
If you use an inapplicable qualifier (for example, if you use
the Connect_Timeout qualifier when you start replication on the
standby node), the Hot Standby software returns an error message.
NOTE
Whenever you specify a qualifier on the Replicate After_
Journal Start command line, you must also include the
Master_Root or Standby_Root qualifier, as appropriate,
on the command line. For example, to change the value of
the Synchronization qualifier on a master database node,
you must specify both the Synchronization and Standby_Root
qualifiers.
