Migration of SAP OS systems (between different operating systems)
The dataowner should be the adm of the target system, which you can change (in the Unix console) with "chown adm K12345.DEV" (respectively R12345.DEV for the data file). To change the access permissions, you can use the command "chmod 664 K12345.DEV". Attach transport jobs in the SAP system Once this has been done, you can attach the transport orders in your SAP system to the import queue. This is done by using the STMS -> Import Overview (F5) to display the import queues. Select the import queue of the target system with a double click. After that, you will receive a pop-up under "Additions"->"More orders"->"Attach", which you can use to attach the transport orders to the import queue. In the pop-up you have to name the exact transport order. The correct name for this is as follows: The first three characters are the file extension of the two files you copied into the transport directory. The last characters consist of the file name of the cofiles file. In our example transport the transport would be called "DEVK12345" (deriving from the cofiles file K12345.DEV) This should now return a positive message from SAP and the transport is attached to the import queue. Now you can import this transport into the system just like any ordinary transport order. Step-by-step Summary Copy Cofiles/data file to transport directory Normally /usr/sap/trans, if not —> AL11 -> DIR_TRANS Customise file owners and permissions chown adm chmod 664 In SAP system: STMS -> Import Overview -> Select Import Queue -> Additions -> Additional Jobs -> Attach Enter Transport Jobs ().
SAP Basis is structured as a classic three-tier model. It contains the following components: Database layer (relational database management system) / Application layer (application server and message server) / Presentation layer (graphical user interface).
Definition of general system parameters
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.
On www.sap-corner.de you will also find useful information about SAP basis.
Verify that the data file was generated. If it was not created, make sure that the [Page 10] Recreate Data File settings in SPAM settings are enabled. For more information, see Note 70752. ADD_TO_BUFFER In this step, the queue is placed in the transport buffer of your system.
With "Shortcut for SAP Systems" a tool is available that greatly facilitates some tasks in the SAP basis.
Prerequisites For example, you need a Windows 7 or a Windows Server 2012 instance on which the Precalculation Server is installed to operate the Precalculation Server.
So much information... how can you keep it so that you can find it again when you need it? That's what Scribble Papers is great for.
To avoid any disagreements, "Mining" is used as one of the possibilities.
