Does anyone know how to create dynamically named restore points? I have an RMAN script that is currently setup like this:

sql 'drop restore point lv_restore';
sql 'create restore point lv_restore';
backup database plus archivelog;
delete noprompt obsolete;
exit;

The first line is where I drop the restore point and the second line is where I create it again. This way the restore point is set just before the backup begins.

Okay - it's setup like this because when I don't drop the restore point ahead of time I get the following error:

sql statement: create restore point lv_restore
RMAN-00571: =================================================
RMAN-00569: ======== ERROR MESSAGE STACK FOLLOWS ===========
RMAN-00571: =================================================
RMAN-03009: failure of sql command on default channel at 04/29/2008 15:22:44
RMAN-11003: failure during parse/execution of SQL statement: create restore point lv_restore
ORA-38778: Restore point 'LV_RESTORE' already exists.

This makes sense to me, actually. What I would love to do is to dynamically append the current date to the end of the restore point name. The idea is to have the restore points named something like this:

lv_restore_2008-04-25
lv_restore_2008-04-26
lv_restore_2008-04-27
lv_restore_2008-04-28
lv_restore_2008-04-29

etc...

Is there any way I can dynamically name restore points?
