Configure SAP's Transport Management System (TMS)
The application layer is the core of an R/3 SAP Basis system. This layer communicates in both directions, to the presentation layer and to the database layer. The application programs on the application servers request the required data from the database layer, process it, prepare it for the user and pass it on to the presentation layer. Data that the user enters in the SAP GUI is passed on to the database via the application servers.
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.
REDUCTION AND AVOIDANCE OF ORGANISATIONAL INCENTIVES
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.
New risks in SAP HANA: In addition to the known risks, there are also new risks from the use of SAP HANA. A very good example are frequently used web applications that represent something new in the SAP area. In contrast to an SAP ERP system, HANA systems consist mainly of web applications, which were considered optional in the previous versions. These web applications can be found by various search engines on the Internet. This also applies to SAP Portal or Netweaver. There are URL schemes that help locate the system. This also applies to other SAP systems that use Web applications. This makes the new technology vulnerable to typical web attacks. SQL Injection, ABAP Code Injection, or XSS are all included. All risks known for a normal SAP system also apply to a SAP-HANA system. The data is stored unencrypted in RAM. Only then does the system gain this speed advantage. This results in risks such as a read-out by memory scraping malware. These pick up data in memory. Encryption costs performance, so it is not used by default. Especially during a migration HANA runs in a parallel system, therefore at least one new system comes to your landscape. Also note: HANA has its own tools and settings that need to be known and configured. The bottom line is that the system simply needs more attention when operating. Many settings often result in more errors. Three - points - HANA Security Plan 1) Roles and permissions In a previous SAP system, roles and permissions are certainly one of the main pillars of a secure system. Roles and permissions work differently in a HANA system. There are two types of users: 1) Default (limited): With this type of user, there are different access methods to the database. For example, the JDBC or HTTP technologies are used to give two examples.
Tools such as "Shortcut for SAP Systems" are extremely useful in basic administration.
The abap/heap_area_total parameter defines how much private storage all workprocesses can use in total.
Furthermore, you need access to the file system or the SAP directories, as they have to insert the above files there manually.
