‣So what does Essbase look like in 12c?
OBIEE 12.2.1 - Initial Release of OBIEE 12c

info@rittmanmead.com www.rittmanmead.com @rittmanmead 4
•Essbase has been supported a datasource for OBIEE since OBIEE10g
‣BI Server translates Logical SQL queries against RPD into MDX
‣Specific MDX function calls can be passed through (EVALUATE etc)
‣Incremental improvements over years to better support Essbase specifics)
•Hyperion Planning & HFM also supported as sources
•SmartView ships with OBIEE with
dual Essbase/OBIEE connectivity
Essbase and OBIEE Integration Since OBIEE 10g

•Essbase and Hyperion Planning as datasources
‣HFM via EAL
•Replace EPM reporting/dashboard tools
‣WebAnalysis
‣Visual Explorer
•Tighter integrations with Financial Reports

info@rittmanmead.com www.rittmanmead.com @rittmanmead 6
•Access data in Essbase cube to add as measures / attributes in report
•Combine (federate) with other datasets (relational, Hadoop etc)
•Include planning data with actuals in BI dashboard
•Make use of Essbase calculations and forecasts for BI data
Oracle Essbase as a Data Source for OBIEE

info@rittmanmead.com www.rittmanmead.com @rittmanmead 7
•OBIEE from version 10g connects to Essbase Server as a data source
‣OBIEE11g min Essbase release 11.1.1.3
‣OBIEE12c min Essbase release 11.1.2.+
•Optional pass-through of Essbase username/password
‣Leverage Essbase data filters and meta filters for row-level security
•Separate OBIEE and Essbase security models
‣SSO possible but one-way only
‣Uses CSS Token generated by BI Server
•Minimum integration but max flexibility
‣Standard approach for most use-cases

•As well as being sold separately and as part of Oracle EPM Suite, it can also be licensed as
part of a complete Oracle BI Foundation platform
‣Sold as a tightly-integrated OLAP server well-suited to sales reporting-type scenarios
•Co-installed with OBIEE and Oracle RTD
•Omits features such as Shared Services
and applications such as Planning, to
focus solely on BI-type scenarios
•Most of as assumed this was just
packaging and cross-selling from Oracle,
Essbase would still just be Essbase…

•Essbase in this scenario is all about BI - making OBIEE faster and more fully-featured
•Adds an enterprise-class OLAP server to the stack, deeply integrated
‣Goes one-better than Tableau, Qlikview etc - ASO in-mem OLAP vs. simple query cache
•All integration work in this context is about making BI run better,
not replacing Essbase-specific tools or removing EPM Suite
•And the primary use case is query acceleration
‣Faster Analysis and Calculations
‣Business Agility
‣Immediate Visibility
‣Adapt to changes
‣Accurate models
Essbase As Query Accelerator for OBIEE

info@rittmanmead.com www.rittmanmead.com @rittmanmead 10
•Runs the BI layer on a high-performance, multi-core, 1-2TB server
•In-memory cache used to accelerate the BI part of the stack
•OBIEE Summary Advisor identifies aggregates based on
previous queries, creates in TT or DB12c In-Mem
•Uses Oracle TimesTen for Exalytics, or Oracle 12c DB In-Mem Option
‣Consistent response times for queries
‣In-memory caching of aggregates
‣40 cores for high concurrency
‣Re-engineered BI and OLAP software
that assumes 40 cores and 1TB RAM
•Works well, and can be great solution for IT-led projects
But … Isn’t This What Exalytics + TimesTen Was For?
ERP/Apps DW
Oracle BI
In-Memory DB/Cache

info@rittmanmead.com www.rittmanmead.com @rittmanmead 11
•Selectively creates aggregations that would have made historic queries run faster
‣Approach driven by limits on TimesTen memory on An Exalytics server
•Does not pre-compute all aggregations, and needs refining and updating over time
•Coupled with TimesTen immaturity, in hindsight not a great solution
Limitations with the Summary Advisor / TT Approach

info@rittmanmead.com www.rittmanmead.com @rittmanmead 12
•Use Essbase ASO engine to provide the aggregation / calculation features for OBIEE
•Potential to aggregate and load the entire RPD dataset into ASO - very space-efficient
•No need to continuously identify aggregate candidates - aggregate everything
•Fast ASO aggregation times compared to TT - quicker to refresh
•Sounds great - why not try this?
Another Option : Essbase As Query Accelerator

info@rittmanmead.com www.rittmanmead.com @rittmanmead
•OBIEE 11.1.1.6.2 BP1 introduced Aggregate Persistence into Essbase
‣OBIEE’s Administration tool had the
ability to define aggregates, and then
persist them in an RDBMS
‣BI Server then uses these aggregates
to speed up dashboard queries
•This OBIEE bundle patch enabled
storage of these aggregates in an
Essbase ASO database, using
headless Essbase Studio

•OBIEE 11.1.1.6, and the 11.1.1.6.2 BP1 bundle patch, included Essbase + administration
tools as part of the install bundle, but these are not by default enabled
•Needs to be patched to 11.1.1.6.2 BP1, then installed using options in a reponse file
•Configures Essbase as part of the OBIEE domain, with EAS and Studio also available
•Narrow use-case : only for Aggregate Persistence, cannot scale-up, repurpose etc

•Combines the flexibility of BSO models with ASO performance
•BSO traditionally used for r/w planning-type applications, typically now in-memory
•ASO used for rack-and-stack BI-type applications, level 0-writes only
•Hybrid takes ASO engine and layers ASO aggs over BSO level-0 blocks
•100% backward compatible with existing BSO databases
•Translates BSO calc scripts to MDX functions
•Can run in-memory
•Part of a move towards a single Essbase engine (over time…)

•A selected member which will collect the data from rejected records of the dimension
•Ensures that totals presented by Essbase after data load match source system totals
‣Previously, Essbase totals would reflect just the members that loaded OK
‣Renegate member feature ensures all values are loaded, if only into new “others” bucket

•Yes - and this is the recommended approach for showing Essbase data in OBIEE12c
‣Query accelerator is “behind the scenes” and invisible to end users
•Minimum supported version of Essbase is 11.1.2+
… And Can We Still Access Standalone Essbase?

info@rittmanmead.com www.rittmanmead.com @rittmanmead 41
•Latest version available as an on-premise, standalone install
‣As shipping with Exalytics, EPM Suite etc
•Recent enhancements to core Essbase server include
‣In-Place write reduces database fragmentation
‣Continue to enrich the calc language
‣Background write deliver high performance for NFS with Exalytics
‣Anonymous data export
‣Controlled shutdown, eliminates most DB corruption issues
‣Smartview Calc Script launcher with context-aware substitution variables
‣Continues to be invested in and available as standalone OBIEE datasource
‣Minimum version supported by OBIEE12c is 11.1.2.x

•Does not handle more complex, and larger, RPDs - use with caution
•Limited ability to customise storage settings for Essbase cube
•Not a solution for Essbase reporting or custom cubes - it’s all about query acceleration
•Treat as experimental and early access - it’s “supported” by
•In general, we recommend standalone Essbase 11g (11.1.2.+) for general Essbase reporting
•But … a taste of the future
