nZDM available in DMO? (not standard SUM)

[former_member146669]

Dear folks,

As i know that there is near Zero Downtime Minimized option in SUM (as show in attached screen cap).

Anyone know that if this option exist in DMO (as part of SUM which is ideal option for HANA migration) as well?

I go through the document & blog of DMO, the term and option of nZDM is not mentioned.

Sorry that i should test myself but I don't have enough to prepare the source system,  tools and xml..etc..and have to propose the downtime optimize for HANA migration project soon...

Please advise.

Thank you.

Gary

Dear Gary,

no, DMO does not support the near Zero Downtime Maintenance (nZDM) option.

For reducing the downtime during DMO, the "downtime optimized DMO" is the possible technique, currently "available on request", see

• nZDM reduces the downtime by updating big application tables already during uptime (and replay the delta created) for an update/upgrade
• downtime optimized DMO reduces the downtime be migrating big application tables already during uptime (and replay the delta created) for update&migration (DMO)

Hi

Just wanted to see if you can share some inputs as to how the business outage/downtime can be reduced to bare minimum  while moving BW on Oracle to BW on HANA ...looking at around 8TB source system oracle DB ..
