Regardless of what script/TDP/etc. is used, sending (two copies of)
archive logs to two separate tapes is done using TWO storage pools.  

One way to do this is via "copypool", which depends on timely execution of
an admin command;  another way (most dba's prefer) is to use 
"-archmc=ARCH1" (and ARCH2, respectively), sending two copies across the
network.  Large business customers liked this approach -- UNTIL the new v5
feature arrived! The new v5.1 feature -- send the primary & copypool once,
have TSM write that single instance to primary & (1 or more) copy pools at
that time.

As always, there are several ways to accomplish, just not the one that
Joni's customer tried to do -- need collaboration of dba & TSMadmin.

Hi,

if they use "Tivoli Data Protection for Oracle" then you can assign
a different management class (= different storagepool) for every copy
of the archive logs and therefore send them to different tapes.

Betreff: Dual copy of files


Hello!

I have a user that wants 2 copies of their database logs on 2 different
tapes (the onsite tape storage pool is collocated).  They thought that by
archiving the file twice several days apart that it would be on different
tapes (just in case a tape went bad or it never made an offsite copy due
to
a tape problem).  Is there a parameter or a certain file configuration
that
would allow the user to have 2 copies of the same logs on different tapes?
As of now the only way I can think to do this is to create another onsite
tape storage pool and have them archive their data to both pools.  Is
there
a better way?  Thanks!
