After a long and painful delivery, I’m delighted to announce the arrival of a new addition to my household … : This custom-build from Scan 3XS is sat in my study quietly humming away. I’m going to use it for hosting VMs for R&D on OBIEE, Big Data Lite, Elastic, InfluxDB, Kafka, etc. I’ll blog various installations that I’ve done on it as a reference for myself, and anyone else interested.

Oracle’s excellent Big Data Lite VM has been updated, to version 4.5. Download it here Changes: CDH 5.5 -> 5.7 Big Data Spatial and Graph 1.1 -> 1.2 Big Data Discovery 1.1 -> 1.2 Oracle Big Data Connectors 4.4 -> 4.5 Oracle NoSQL 3.5 -> 4.0 GoldenGate 12.2.0.1 -> 12.2.0.1.1

I’ve been spending some interesting hours digging into OBIEE 12c recently, with some interesting blog posts to show for it. Some of it is just curiosities discovered along the way, but the real meaty stuff is the in the RESTful APIs - lots of potential here for cool integrations I think… Lifting the Lid on OBIEE 12c Web Services - Part 1 Lifting the Lid on OBIEE 12c Web Services - Part 2 Extended Subject Areas (XSA) and the Data Set Service Changes in BI Server Cache Behaviour in OBIEE 12c : OBIS_REFRESH_CACHE Dynamic Naming of OBIEE 12c Service Instance Exports OBIEE 12c - “Add Data Source” in Answers (Photo credit: https://unsplash.

Presentation Services can provide some very detailed logs, useful for troubleshooting, performance tracing, and general poking around. See here for details. There’s no bi-init.sh in 12c, so need to set up the LD_LIBRARY_PATH ourselves: export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/app/oracle/biee/bi/bifoundation/web/bin/:/app/oracle/biee/bi/lib/:/app/oracle/biee/lib/:/app/oracle/biee/bi/bifoundation/odbc/lib/ Run sawserver with flag to list all log sources /app/oracle/biee/bi/bifoundation/web/bin/sawserver -logsources > saw_logsources_12.2.1.txt Full list: https://gist.github.com/rmoff/e3be9009da6130839c71181cb58509a0

In OBIEE 12c data-model-cmd is a wrapper for some java code which ultimately calls an internal RESTful web service in OBIEE 12c, bi-lcm. We saw in the previous post how these internal web services can be opened up slightly, and we’re going to do the same again here. Which means, time for the same caveat: None of these Web Services are documented, and they should therefore be assumed to be completely unsupported by Oracle.

exportServiceInstance will export the RPD, Presentation Catalog, and Security model (application roles & policies etc – but not WLS LDAP) into a single .bar file, from which they can be imported to another environment, or restored to the same one at a later date (e.g. for backup/restore). To run exportServiceInstance you need to launch WLST first. The following demonstrates how to call it, and embeds the current timestamp & machine details in the backup (useful info, and also makes the backup name unique each time).

So this had me scratching my head for a good hour today. Comparing SampleApp v511 against a vanilla OBIEE 12c install I’d done, one had “Add Data Source” as an option in Answers, the other didn’t. The strange thing was that the option wasn’t there in SampleApp – and usually that has all the bells and whistles enabled. After checking and re-checking the Manage Privileges option, and even the Application Policy grants, and the manual, I hit MoS - and turned up Doc ID 2093886.

I had the pleasure of not one but two fry-ups in York, UK last weekend. The first was courtesy of Bill’s Restaurant Overall, pretty good, and I’ve had much worse. All the ingredients seemed decent. The black pudding was overcooked and almost biscuit-like, but that’s my only serious grumble. The bacon was cooked well. That black pudding, beans and the mashed/friend potato thing were each extra charges annoyed me. Particularly with a hangover, I just want to be able to order a full english, without playing Mastermind to work out what’s in or not.

Architecturally, OBIEE 12c is - on the surface - pretty similar to OBIEE 11g. Sure, we’ve lost OPMN in favour of Node Manager, but all the old favourites are there - WebLogic Servers, BI Server (nqsserver / OBIS), Presentation Services (sawserver / OBIPS), and so on. But, scratch beneath the surface, or have a gander at slide decks such as this one from BIWA this year, and you realise that change is afoot.

I wrote recently about Kibana’s excellent Timelion feature, which brings time-series visualisations to Kibana. In the comments Ben Huang asked: do you know how to show whats the difference between this Friday and last Friday by Timelion? So I thought I’d answer properly here. Timelion includes mathematical functions including add and subtract, as well as the ability to show data offset by an amount of time. So to answer Ben’s query, we combine the two.
