How does a blockchain build consensus? Once you decide to send a payment to someone, you must use the Private Key to "sign" it (in German: signature). This means nothing other than that you specify another public address to which you want to send the money and confirm this transaction with your own private key. You don't have a central authority to send the information to, you're going to spread the information to all the other Miners around you. The miners then forward this information to other miners, who in turn do the same. This exponential wave of information reaches the entire network of the distributed community within a few milliseconds. Every time a miner receives a transaction, it checks that the transaction is actually correct. It checks which private key has signed, which public address the transaction should go to and whether the sender has enough "coins" for this transaction. What are consensus mechanisms? Any miner that solves a transaction through complex mathematical calculations is rewarded by the sender with a "fee" (transaction fee). How will it be decided which miner will receive the transaction fee? Because only one can get this reward. Also, what happens when you try a double spending by sending one transaction to one miner and then another transaction with the same money to another one millisecond later? These two could not yet exchange and thus information would be different in the network.
The Advanced Memory thus contains mainly user contexts of different work processes, if these cannot be loaded completely into the roll area. Since the storage area is accessible for all work processes, the work processes can also access external user contexts that lie here. In addition, the Advanced Memory contains a global area where data can be stored independently of user contexts. The extended memory size is determined by the values of em/initial_size_MB and em/global_area_MB. The first parameter determines the size of the storage area in which user contexts can be stored, and the second determines the size of the global area. Parameters for Private Storage Last but not least, there is the private storage, which is only used when the user context of a work process has used up all the other storage areas available to it, i.e. its share of the extended memory and its rolling area. In this case, the workprocess goes into PRIV mode. A workprocess in private mode is bound to its current user context and will not become free for other tasks until the current request is completed. If it has used up all the private memory allocated to it, the workprocess will then be restarted and the memory released. This behaviour is controlled with the abap/heaplimit parameter. At times, the user context may exceed the value of abap/heaplimit. The parameters abap/heap_area_total, abap/heap_area_dia and abap/heap_area_nondia define an upper limit for private storage. The abap/heap_area_total parameter defines how much private storage all workprocesses can use in total. The parameters abap/heap_area_dia and abap/heap_area_nondia, on the other hand, determine how much private storage a single (non-)dialogue workprocess can use.

SAP Basis Management
In order to explain the relationship between TREX and SAP Solution Manager, I would like to ask you a question first. Can you remember when you last used the search help (F4) in SAP, what you were looking for and above all what the search string looked like? Now, the entitlement admin might have looked like this. Any role for a new key-user in the HCM area, but how exactly was that called? Would you Google the same way? - Not much. The Enterprise Search in Solution Manager 7.2 In the SAP Solution Manager, the SAP Enterprise Search provides a comprehensive full-text search. With only one keyword, you can search centrally for all types of documents in the ITSM and ChaRM, such as incidents or changes, via the Fiori Launchpad. If you have added attachments, they will also be searched for the keyword. At a technical level, a special BOL query object is passed to the Enterprise Search, which passes the HANA database and performs a search. What if you don't use the Solution Manager on SAP HANA? Enterprise Search with TREX 7.1 SAP offers the possibility to use Solution Manager 7.2 on another database (AnyDB), for example DB2 or Oracle. In order to use Enterprise Search (also embedded search) in this case, you need the TREX admin tool. This stands for Text Receival and Information Extraction, which basically describes the functionality of the software. The TREXEngine takes the search text in the form of the Query object and provides an intelligent search of keywords and long texts in previously classified documents. Installation and Usage Tips Run the TREX configuration after the basic configuration of the Solution Manager. In SOLMAN_SETUP you will find the Embedded Search scenario, which is the guide for the configuration. In the Process Management scenario, configure the embedded search using the description. Here the object connectors are created and the indexing jobs are started. Both are required to use the solution documentation in conjunction with other components. If you are installing UNIX, make sure that the shared libraries are up-to-date or that they are initially available.
Since innovations through IoT (Internet of Things) or big data scenarios not only affect the SAP basis, but also highlight products and services for customers of their own company, the role of the SAP basis in relation to these scenarios and services must be clearly defined. In general, the SAP basis sees its responsibility here in the connectivity to the corporate network or the enterprise systems, which lie in the responsibility of the SAP basis. The support of the applications, based on the technologies as well as the associated services, is the responsibility of the respective department that offers this service. A SAP-based support service must be agreed and regulated during the conception.
Use "Shortcut for SAP Systems" to accomplish many tasks in the SAP basis more easily and quickly.
