Essbase Version Archaeology

I was digging through some of the Essbase Java API internals the other day, trying to work around an issue I was encountering with Vess, my Essbase JDBC driver. Along the way I came across a constants file with a fun history (of sorts) of Essbase versions.

Complex software packages will often track their version somehow. This is for many reasons, but a very common one is so the software has a way to gracefully handle version discrepancies. For example, some client software (perhaps the latest version of Smart View) may be working with an older version of the Essbase server. If there was some feature that came out that Smart View supports but isn’t available in the older version of Essbase that it’s connecting to, it might find this out by asking the server for its version. The client can then hide/disable the feature as needed.

That said, the Essbase Java API has a file that tracks various versions of Essbase. This shouldn’t necessarily be interpreted as a full version history, but when the Essbase developers need to make a change that could affect version compatibility, it will often result in a change to the internal version matrix.

In any case, the constants in the file tell kind of an interesting story. We can see a handful of code names in the variables, such as Gemini, Orion, Levi, Sunspot, Eclipse, Cromwell, and Beckett.

Other versions are just designated by a major/minor/patch/build combination, such as Essbase 6.2, 6.5, 6.5.1 (this is the version of Essbase I cut my teeth on!), 7.0.0, 7.1, 9.0.1,,, 9.2.1, 9.3.1 (one of my favorite versions), and

Then the jump to version 11 happens, where we can see 11.1.1,,, 11.1.2,,,,, and

Curiously in the 11.x series, at some point there was an introduction of a seemingly separate series of variables, for editions PV0, PV0, and PV1. I’m not totally clear what the PV is meant to indicate (patch version?).

Lastly, at some point someone introduced a set of three variables to track the release/revision/patch that would apparently always be the current version of the API, but it was only ever set with major version 6, minor version 5, and patch 0. I think someone decided that the variable structure, while seemingly clean/useful, was untenable in the long haul.

Lastly, there are a couple of “versions” that coincide with specific features that came out or were otherwise necessitated by testing: ECLIPSE_ALPHA, ECLIPSE_ALPHA_II, Hybrid Analysis (HYBRIDANALYSIS), non-unique names (NONUNIQUENAME), UNICODE, and some sort of “parity” (PARITY) marker that has the same version as Un unqualified version variable seems to match up with the version of the library itself (I took this from an JAR file, hence it matches the entry for

I remember an Oracle product manager at some time indicating that the code names for Essbase versions were authors – hence Beckett and Cromwell – but I also distinctly remember hearing that one of these versions was codenamed “Tallyrand”, which isn’t reflected in the code names for this list. I’d be curious what some of the other code names were along the way, so if anyone out there knows, please send me an email and I can post them here for posterity (if nothing else).

Here’s the full list from the file from for those that are curious:
