Administrators often need to replicate part or all of a database, for example, to create a system backup or test an upgrade before putting it into production. In the past, this was surprisingly difficult to do with most databases. With HANA, replication works instantly and offers richer features and better control than previous databases.
The default value of the profile parameter is 1, so the weak hashes are generated for each user. Preventing weak password hashes The generation of unsafe hash values can be prevented by setting the login/password_downwards_compatibility profile parameter to 0. Note that a change only takes effect when the instance is restarted!

The CodeProfiler prevents poor-quality code or programs with security vulnerabilities from entering a productive SAP system landscape in the first place. It is therefore important to use the CodeProfiler throughout the entire lifecycle of a software. Already during programming, the CodeProfiler helps the developer to identify and correct errors and vulnerabilities in the SAP landscape. The CodeProfiler automatically ensures that only "clean" code is transported to the next level (development system -> test system -> quality assurance system -> production system). The CodeProfiler can also be used for regular review cycles.
In order to make a transaction in cryptocurrencies, you do not have to let your bank know about it as you would for "normal" money, but you have to use the Private Key to prove that you own the coins. The transaction looks like a piece of the puzzle. Half of the puzzle piece consists of information about the coin set, time and public address of the sender or receiver. The other half is the signature of the private key belonging to the sent public address. Both halves make this piece unique. Changing only one piece of information would completely change the whole transaction or the appearance of the puzzle piece. This transaction is transferred to the network or to the miner and is checked for correctness first. If everything fits, the transaction will be sent to other miners who will do the same. Otherwise, the transaction is ignored. Miners try to integrate the transactions into a block. This is called mining and we have described it so that the miners put the puzzle pieces together into a puzzle (block). A small part of a block to be integrated follows from the block that was previously mined. If all miners accept the correctness of a completed block, they will all work the next one immediately. The puzzle (block) is fixed and is irrevocably connected to the block before or after. The blocks form a chain and are called blockchain, which contains all the transactions that have ever been made and is visible and unchangeable by everyone. In doing so, blockchain replaces a central institution and avoids double-spending, which ultimately gives value to a cryptocurrency. Smart Contracts The biggest advance compared to Bitcoin and similar applications is that second-generation blockchains, such as Ethereum, use the so-called Turing-Complete script language Solidity. This enables calculations to be made within the blockchain. While Bitcoin allows only rudimentary multi-signature functions, Ethereum opens the door to much more complex operations called smart contracts. Smart contracts are contracts in which a decentralised blockchain ensures their unchangeability and execution.
Tools such as "Shortcut for SAP Systems" are extremely useful in basic administration.
Understanding the structure and functioning of the system is especially important for IT administration. It is not for nothing that "SAP Basis Administrator" is a separate professional field. On the page www.sap-corner.de you will find useful information on this topic.
In the case of client settings, you should ensure that the production client is protected against overwriting and that changes are only approved via the transport management system (TMS) to ensure traceability.
Therefore, apply the following procedure for uninstallation, no installation of SAP should be visible anymore: Order: 1) SAP BW Precalculation Service 2) SAP Business Explorer 3) SAP GUI for Windows XY Note: During the installation and uninstallation of individual components, the progress bar status may be suspended at certain locations.
