The company has been using it for many years and I have been using it for just over 2 years. I feel the ease in obtaining the data. The solution can fit scenarios where there is quite a high workload and a low response time. Queries and transactions occur in milliseconds. Other backup/restore, replication and other features are fundamental and work exceptionally well. IBM is one of the most reliable companies and has been in the market for years in this segment and has helped us with support whenever we need it.

Some scenarios where SAP BW/4HANA is well suited are retail industry, supply chain, finance, warehouse, stocking processes, BI, [and] some finance analytics reporting. Some scenarios where SAP BW/4HANA is less appropriate [is when] relational queries are needed [and] in some small business with infrastructure limitations. Another scenario that is less appropriate is for ABAP processes requirements.

The Task Scheduler component of DB2 allows for statistics gathering and reorganization of indexes and tables without user interaction or without specific knowledge of cron or Windows Task Scheduler / Scheduled jobs. Its use of ASYNC, NEARSYNC, and SYNC HADR (High Availability Disaster Recovery ) models gives you a range of options for maintaining a very high uptime ratio. Failover from PRIMARY to SECONDARY becomes very easy with just a single command or windowed mouse click. Task Scheduler ( DB2 9.7 and earlier ) allows for jobs to be run within other jobs, and exit and error codes can define what other jobs are run. This allows for ease of maintenance without third party softwares. Tablespace usage and automatic storage help keep your data segmented while at rest, making partitioning easier. Ability to run commands via CLI (Command Line Interface) or via Control Center / Data Studio ( DB2 10.x+) makes administration a breeze. Read full review High speed data warehouse regardless of data volumes. Excellent integration with SAP systems and Data sets. Simplified data modelling due to columnar data base. Read full review Cons The relational model requires a rigid schema that does not necessarily fit with some types of modern development. Proprietary database, requires a lot of Hardware for its good performance and its costs are high. As data grows in production environment, it becomes slow.

Live connection is only read from SAC. Make run-time licenses more useful. Read full review Likelihood to Renew
Since our services are running in IBM Kubernetes, using IBM Cloud Databases seem to be the best option. It may provide better performance than other vendors as everything is running in the same cloud. The overall experience so far is good as well.

You have to be well versed in using the technology, not only from a GUI interface but from a command line interface to successfully use this software to its fullest.

SAP BW/4HANA requires specialized skillsets around data warehouse modeling and the access to data, however the modeling capabilities are intuitive and have now become accessible to both SAP and non-SAP data warehouse specialists. This new model allows for Interchangeable skillsets and access to a broader pool of experts throughout the industry, as well as easier access to data.

Any issues related to DB2's availability are usually resolved easily and fast. We also have a team of dedicated analysts and admins to support the database technically. Once in a while we do request support from IBM for some complex issues that the on premise team can't resolve and the response is usually pretty fast and support is amazing!

The performances are exceptional if you take care to maintain the database. It is a very powerful tool and at the same time very easy to use. In our installation, we expect a DB machine on the mainframe with access to the database through ODBC connectors directly from branch servers, with fabulous end users experience.

SAP Max Attention and general support for SAP BW/4HANA is broadly available. Truth to be told, MaxAttention has a premium cost but brings great engineers. So this being an enterprise capability and extremely critical, we did not consider cost as the main factor since support works well. Just keep that in mind when making your selection.

Db2 is one of the best relational databases I’ve used. It has the ability to maintain large amount of data and execution of million transactions in fraction of a second. If you use it properly, an organization can build a database with thousands of tables, and it can provide the exact information for the applications within a short amount of time

integrates with BW/4 HANA allowing to automate the loading of information in the system taking as a data source a wide variety of platforms.
Read full review Scalability
using DB2 only to support my IzPCA activities, my knowledge here is somewhat limited.
from what I was able to understand, DB2 is extremely scallable.
Maybe the information below could serve as an example of scalability.
Customer have an huge mainframe environment, 13x z15 CECs, around
80 LPARs, and maybe more than 50 Sysplexes (I am not totally sure about this last figure...)
we have 7 IzPCA databases, each one in a distinct Syplex.
are underway to have, at the end, an small LPAR, with only one DB2 sub-system, and with only one database, then transmit the data from a lot of other LPARs, and then process all the data in this only one database.
IzPCA collect process (read the data received, manipulate it, and insert rows in the tables) today is a huge process, demanding many elapsed hours, and lots of CPU.
100% of the tables are PBR type, insert jobs run in parallel, but in 4 of the 7 database, it is a really a huge and long process.
the INSERTs loads from the 7 databases in only one will be .......,,,, impossible But, IzPCA recently introduced a new feature, called . "Continuous Collector"
using that feature, small amounts of data will be transmited to the central LPAR at every 5 minutes (or even less), ,in processed immediately a short period of time, and with , small use of CPU instead of one or two transmissions by day, of very large amounts of data and the corresponding collect jobs occurring only once or twice a day, with long elapsed times, and huge comsumption of CPU
I suspect the total CPU seconds consumed will be more or less the in same both cases , but in the new method it will occur in small bursts many times a day!! Read full review Return on Investment Has reduced the downtime or outages due to HADR features which we lagged earlier. No manual intervention needed in most situation for us. IN worst case TSA does automatic failover so its transparent for the apps. LOB support is little bit problem for us now which we hope will have some improvement in product in future.
