And with the launch of new DB2 version 10 in LUW the excitement is overwhelming; suddenly a question flashed in my mind. No it is not about new features and enhancements of latest release, rather i am going to take a historical tone.

Was there a DB1 before? When they released new relational db I guess it become database 2. The first stab at creating a data language to describe objects that followed the relational rules laid out by Dr. I took a stab at it and my memory as I worked with all this stuff CIRCA when I started working with performance monitoring tools.

Hence the wrong nomenclature is common. Codd developed the relational algebra which is mostly DBMS agnostic and can be used for the design of IMS as well as relational databases. But more modern we could say it is a Database to 2. I had learned also that when developing the relational model, they were working on a commercial offering… were beat to market by a Company called Relational Database?

There was a DB1 in the s. It was a development environment from Israel later renamed to Sapiens. Whoops, let me correct myself: the 2 in Oracle 2 was the version number, as in Oracle 3, Oracle 4. And now Oracle 11g. As a result, I created a relational design that was implemented in a hierarchical database and that gave the design boys in Slough at least, I think it was Slough , England, a bit of heartburn when they verified that my design would work.

I worked on the development team, documenting the product, beta testing, and working on the query language. The product was sold to IBM while I worked there, I think, but that was a quite a long time ago. There were a couple of funny stories about that, too! He was a genius and he taught me system analysis … in 4 weeks of 10 hour days. Then I had to relearn everything when i moved sideways into object linked database design 10 years later. I know the history of how and why it was created, in case anyone is interested.

This compensates for the sense of shame on hearing that much of Microsoft XP was developed in Israel. One question: did the Weizman Institute have the wits to negotiate a royalty on subsequent licence sales?

Best regards Alex. Above my pay grade. But my boss got nice and rich and probably so did the rest of the originally group … not, of course, me … I seem to have a real knack for missing the part of the development process where money gets made. I am baffled at how he can suddenly only be only a year older than me, because he was at least 5 years older than me 30 years ago. It is possible to issue a forced or non-forced takeover on any standby, including the delphix auxiliary standby.

However, you should never use the Delphix auxiliary standby as a primary, because this will impact Delphix performance.

Releases Virtualization Delphix 6. Delphix Engine 5. DB2 on Delphix: An Overview. Delphix DB2 authentication. Delphix will neither create users nor change database passwords as part of the provisioning process.

Delphix DB2 Instances. Delphix operates on the instance level and requires that the staging and target hosts must have the empty instances created prior to Delphix using them, and the instance owners are added as environment users It is important to note that our dSources and VDBs are entire instances and NOT specific databases inside an instance. Delphix HADR. Log Transmitting. By using this mature and existing DB2 capability, the Delphix Engine is able to ingest data and keep the standby server in sync with only a minimal impact on production.
