To obtain a list of obsolete archived redo log files that are not needed by Dbvisit Replicate anymore and therefore maybe deleted (by RMAN), run the following command in Dbvisit Replicate comand command console:

 

Section
Column
width5%

 

Column
width95
Panel
bgColorCCC
 LIST OBSOLETE REDO [THREAD thread]

The oldest archive log that MINE will ever need is "last obsolete sequence" + 1

The oldest archive log that APPLY wil ever need is the sequence # that APPLY is working on

Scripting the output of the "list status" command

 To automate the management of Dbvisit Replicate further, the output of the list status command can be scripted. 

The commands are:

Section
Column
width5%

 

Column
width95
Panel
bgColorCCC
start-console.sh --silent engine mine send engine status  | grep Sequence
start-console.sh --silent engine apply send engine status  | grep Sequence

The Mine process returns the plog sequence and the redo sequence. If RAC is not used, then this number will be the same.
