ZDLRA ready for Oracle Database 18c

ZDLRA is one of the best acronyms ever. It took me 5+ years to not mix up the sequence of characters 🙂 And even Larry made a joke about the name a while ago at his OOW keynote (I think it was 2016). ZDLRA stands for Zero Data Loss Recovery Appliance. And that basically tells you what it is. Hence, it isn’t a bad acronym as it tells you straight forward what it does. Good news: ZDLRA ready for Oracle Database 18c.

ZDLRA ready for Oracle Database 18c

ZDLRA ready for Oracle Database 18cWhy am I writing about this? Some of the customers I’m working with right now on either a very large migration project to ExaCC or a major upgrade from Oracle to Oracle Database 18c, both have ZDLRAs. And in the latter case, even though their Exadatas could have had the Oracle 18c stack already installed, the ZDLRA was not ready to support Oracle 18c backups.

Now it is. On July 17, 2018 the availability of the  ZDLRA software stack got announced. Please have a look at MOS Note: 1927416.1 (Zero Data Loss Recovery Appliance Supported Versions). And even though the MOS Note is not clear, this is the one which supports Oracle 18c database backups (and of course the recovery as well).

Tim Chien’s and the ZDLRA team’s recommendation: “This is a major V2 release, including support for 18.1 protected databases, and is recommended for all customers.”

Addition Aug 14, 2018

Thanks to Alexey who commented on this blog post, I need to clarify (and I wasn’t realizing this before):
The statement above included only certification for Oracle 18.1.0 databases, but not for 18.3.0. The certification of 18.3.0 databases is expected soon. Sorry for my imprecise statement.

  1. Hi,
    Good to know that.
    Agree, it is not the best acronym (even more if you know that internally they call it just as RA), but if I remember Larry made the same joke in 2015 speech.
    It is a really good product, I had the opportunity to work with ZDLRA since 2015 (until end of 2017 in Bra and now in Lux), speech at OOW2015 with Tim about that too – http://www.oracle.com/technetwork/database/availability/con8830-zdlradeepdive-2811109.pdf

  2. Answer from Oracle Support
    Hello Alexy, supports 18.1 database – as per the Supported Versions Note. 18.3 is still not supported yet. Dev team is working on this and we are not sure when this will be released.


    • You are right – I should have been more precise. Following an internal information I silently mapped this to 18.3.0 as well. Well, I should have better studied the fine print. Sorry for the inconvenience.

      But there are good news as well – 18.3.0 support is not far away.
      I updated the blog post – and will update it as soon as 18.3.0 dbs are supported as well.

      Thanks for alerting me and checking with support!
