Forward looking statements are subject to change
Focus of this session
Is to provide you with technical insights impacting Lumira Deployment and Sizing:
- Your usage scenarios will dictate how to best consider your deployment
- Your specific environment has everything to do with how you would architect
- The sizing guide and Quick Sizer would support you for sizing servers
Customers have different architectures and use cases
Generic sizing principles and guidelines apply – user type, concurrency type, still apply for Lumira
With combining into one product on the back end, there are changes on the back end
Content types impact your environment, and probable impact
Process flow – end users – there are set of request-responses – these interactions depend on components
Size/scale out to cater to new use cases and load by Lumira on platform
Purple are the Lumira components
APS hosts the velocity engine and BICS connectivity
The Lumira Server processes Lumira content on BI Platform. This server hosts the in-memory data engine which is used as an offline data processing engine for Lumira. It is a separate product from HANA but borrows many concepts such as in-memory, column store, parallelization, and compression. Like other documents in BI Platform, Lumira documents are also saved in the Input / Output File Repository servers. The data is loaded into the in-memory data engine only when a user opens a Lumira document.
Lumira Scheduling Service:
Lumira Scheduling Service is a service within the Adaptive Job Server. This server enables the scheduling of Lumira documents.
Lumira Web Application:
The BI Launchpad and CMC applications are embedded in the Lumira Web Application to allow access to Lumira content in the BI applications.
Lumira Restful Web services:
Lumira Restful Web Services provides the web services required by Lumira Desktop to interact with the BI Platform such as login or to save Lumira document. (Source: SAP)
Reconsider sizing for APS, CMS, file repository
Design Studio supports compatibility mode; work with 1.6 applications without touching them
Even though support compatibility mode, after you upgrade add-on, even execution of these applications occurs via Lumira 2.0 server; still need to size your Lumira server to size the documents
Discovery – stories are output
Designer – applications are output
Use the common lumx file format
Resource consumption would be the same – how the content is created / connected to data source – live mode versus importing from data source – this will impact consumption of data source
Live connectivity – delegate calculation to BW/HANA engines
If connect in live mode – Velocity engine doesn’t come into play
If you import the data, makes use of memory on node where Lumira server is running; data is loaded to velocity engine – for either Discovery/Designer
Velocity Engine can consume upto 85% (memory consumed depends on usage, isn’t assigned at start up) system memory (source: SAP)
Other impact is how users are using the application:
Refresh and Analysis have different resource requirement for Imported data connections
- Refresh and Analysis are similar workflow and have similar resource requirements for Live documents, Refresh or Analysis have a different resource requirement for Imported data
- In case of imported data sources, Refresh would result in creating additional workspace to contain data for each users (who has refreshed)
- Same is applicable while saving the document
- Rest all workflows for Analysis e.x. filter, drill, calculations and adding new visualizations would continue to utilize common workspace containing the data across users (source: SAP)
Users who will refresh vs those who use document already created
Process Flow (Source: SAP)
Understanding which components are utilized by the system for your workflows will help you focus on sizing the components accordingly
- Generic BI Platform interaction to Log-on, Listing etc..
- Working with artifacts connecting to Live data sources
- Working with artifacts with imported data
- Refer to for all process flows https://wiki.scn.sap.com/wiki/display/BOBJ/SAP+Lumira+2+Workflows – coming soon
Browse repository, CMS, WACS, and Lumira Server come into play; need to consider additional load
When publishing, have CMS, WACS, Lumira Server and Input FRS come into play
Acquire data from universe – sizing considerations are shown above
Access Input FRS
HANA Live uses BICS or INA connectivity
Similar workflow when using BI Launchpad accessing Discovery document using HANA Live using INA connectivity
HANA Import mode workflow
BW live uses BICS Connectivity
Designer uses the dswsbobje unlike Discovery which uses WACS for all scenarios
Other impacting factors:
Sub optimally sized BI Platform
- Running additional content and increased user concurrency would further impact response and throughput
Poorly provisioned databases will have an invisible effect:
- CMS DB latencies have a cascading effect – one BI admins can’t see!
- Ensure that each reporting database and it’s I/O paths are large enough
- Ensure that each reporting database is configured appropriately for best response
I/O bottlenecks – disk and network – have severe effects:
- Worst thing you can do to an I/O intensive application is to starve it for data
- Being on an underperforming file server can starve the entire BI system
Ensure virtualization hosts can handle aggregate requirements:
- Putting 5 processing server VMs on one host means the host must have at least 5x the IO capability and 5x the RAM! Source: SAP

Question & Answer
Q: is 85% the upper limit that is imposed by LS4BIP? secondly can it be changed by a customer & if yes, how?
Q: Is velocity engine part of Lumira 2.0?
Q: When is the next Lumira webcast?
Q: for a customer already deployed Lumira 1.x & Design Studio, assuming no change in usage patterns would the same sizing be good enough for Lumira 2.0?
Q: Is the BI Platform Lumira Discovery add-on for Solaris still on schedule to be release by Dec 2017
Q: 1. What is the minimum Lumira and DS 1.X versions required to update to Lumira 2.0 SPx Are we supposed to be able to access OLAP connections from SAP HANA/BW Live connector ?
Q: If you have Lumira 2.0 server and already using Discovery, then if you want to start to use Designer (1) Do you need to extra configuration for Lumira Server? (2) Does it affect sizing besides additional users?
Q: Do the client machines need a special sizing too or it’s only required for the server side?
Q: Is there any separate server need to create for lumira designer in CMC ?
Q: Is it possible to use the “Resource Usage Estimator” tool for Lumira or it has to be only with Quick Sizer tool?
Q: Is there a specific process to convert DS 1.x documents to Lumira 2.0 like for Lumira 1.x docs we have to migrate the docs using Lumira desktop 1.31.8
Q: Can we use promotion management to promote .lumx documents? Is there a best practice that needs to be followed?
Q: Have heard that RESTful is moving on Tomcat from WACS so after that the workflow will remain same? or is there any changes?
Q: When we install Lumira 2.0 in same BOE server, Scale up or Scale out is recommended to improve performance?
Q: should Lumira be installed on the CMS and Webi servers even if you don’t plan to run it on this server?
Q: Is Excel a supported data source for refresh(Lumira 2.0 discovery based docs) from BI Launchpad ?
Q: what about using Resource Sizing Estimator for Lumira 2?
