Preparation of full access to SAP systems and solutions in case of disasters (High Availability/Disaster Recovery)
Here, too, the requirements profile for SAP Basis experts has shifted: Database administration is simply part of the job today. The majority of SAP customers place the SAP HANA database in the hands of the Basis team for build and run operations.
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.
SAP Basis is structured in the form of a three-layer model and consists of the following components:
When I began my career administering SAP ERP on Oracle in the early 1990s, running a database required far more knowledge. An Oracle administration expert with a decade of experience understood perhaps only about 5% of what the database required.
You wanted to rush to release a transport order in the quality system of your SAP landscape and accidentally clicked on "Reject" instead of "Approve"? Now the order cannot be transported any further and will soon be cleared by job from the queue? Don't despair: In this blog post, I'm going to tell you a simple way to get rejected transportation to the production system anyway. As a reader of our blog, you are certainly interested in tricks and tricks that will make your SAP system easier to handle. You may be aware of the situation where you want to approve a transport order quickly after the test has been completed and you have clicked in the system when the order was released. The problem now is that the transport order in the system now has a status of "rejected" and can therefore no longer be transported. In total, a transport order may receive important changes that you would have liked to have transported to the production system. Approach to release rejected transport orders The screenshot below shows the situation in the STMS transaction where a transport order in the quality assurance area was rejected. Therefore, an import into the production system is no longer possible. The transport job can be removed either manually or through a job. The question here, however, is how the amendments which were wrongly rejected can be transferred to the subsequent system. Rejected Transport Order Tip: Leave the status on Rejected, remove the rejected transport order from the import queue, if necessary, and follow the next steps. Switch to the import queue in your quality system. Go there via Additions -> More Orders -> Attach to the modal window where you can perform further steps.
Tools such as "Shortcut for SAP Systems" are extremely useful in basic administration.
These files consist of a six-character alphanumeric combination and a file extension, which often represents the system from which the files were exported.
SAP on Azure or on Amazon Web Services (AWS) is a scalable, reliable platform for your current and future SAP HANA requirements.
