I am having some problems trying to do a Disaster Recovery simulation. I have
been through the Admin Reference, the server installation, and the redbook on
Recovery and Disaster recovery, and still can't find what I am looking for.
Perhaps someone can point me in the right direction.
According to the Disaster Recovery Redbook, (section 5.2.6.2 on page 63) Step
1 is to allocate a new DB and recovery log, and options file, and step 2 is to
run the restore for the DB. Unfortunately, they did not give any JCL
examples.
This does not seem to work for me. Here is what I have done:
1. Set up new DB and Recovery log files. This was done through the ANRFMT
process.
2. Have access to existing disklog, history, configuration, and server
options file.
3. I start a batch job executing DSMSERV, with a parm of '/restore db
todate=today'
The result of step 3 is that the restore fails with an ANR0259E message,
stating that it could not find any complete restart/checkpoint information
from the database or recovery log. This of course is true, since I have no
recovery log - it is empty at this point, since it only has been formatted.
Is there a parm available to tell it to skip checkpoint processing? Should
we have run DSMSERV with a "/install .... parm to have it initialize the
recovery log first?
I can see how to reload the DB using DumpDB and LoadDB, but this is not a
practical disaster recovery scenario, since DumpDB requires the server to be
down first.
