Adding Mirrored Dbspaces to a Dbslice

Suppose you have a database server that is using mirroring with two coservers. The following example shows the onutil CREATE DBSLICE command to create mirrored dbspaces on each coserver:

% onutil
1> CREATE DBSLICE dbsl FROM COGROUP cogroup_all
2> CHUNK "/disk3/dbspace/dbsl.%c" SIZE 500 MBYTES
3> MIRROR "/disk4/dbspace/dbsl_mir.%c";

The database server creates the mirrored dbspaces on the coservers.

The following example shows the onutil ALTER DBSLICE ADD DBSPACE command with the MIRROR option to add mirrored dbspaces to dbslice dbsl on each coserver:

% onutil
1> ALTER DBSLICE dbsl ADD DBSPACE 
2> FROM COGROUP cogroup_all
3> CHUNK "/disk3/dbspace/dbsl2.%c" SIZE 1000 MBYTES
3> MIRROR "/disk4/dbspace/dbsl_mir2.%c";

The database server adds mirrored dbspaces to the dbslice on both coservers.
