There are many useful lists of SAP tables on the Internet, but, for one reason or the other, I could not find one overview in the tips and tricks section, which file System Overview my own needs. Banks, Taxes, Clients, Accounting, Payment methods etc. Tables which have technical control functions within the SAP system.
They are maintained either by SAP or by users with special authorization. And last but not least there are tables for application data, which contain business transactions and master data and are processed using SAP programs. Tricks to maintain them, are provided on the linked pages. The work-life-balance: Klingon Programmers with more global approach and a variety of international team members.

Transaction Codes – Overview When I started to work with SAP I got really mad about all these non-sensical 4 digit SAP transactions. I could not find what I was looking for. Of course, there are many useful lists on the web, but, for one reason or the other, I could not find one overview, which suits my own needs. Tip: using transaction code SE16, in the SAP table TSTC all transaction codes can be viewd.
Opens a new session and starts transaction xzy in the session. Lists existing sessions and allows deletion or opening of a new session. Terminates the session with the number given. Fast path: ‘abc’ refers to the underlined letters in the menus. Can either use T-Code in the search criteria or a description. RSUSR002_ADDRESS – User by address data, logon name, etc.

Sun used version 1 only for in-house experimental purposes. When the development team added substantial changes to NFS version 1 and released it outside of Sun, they decided to release the new version as v2, so that version interoperation and RPC version fallback could be tested. You can help by adding to it. The Virtual File System interface allows a modular implementation, reflected in a simple protocol.
The first NFS Version 3 proposal within Sun Microsystems was created not long after the release of NFS Version 2. The principal motivation was an attempt to mitigate the performance issue of the synchronous write operation in NFS Version 2. In 2007 Sun Microsystems open-sourced their client-side WebNFS implementation. Various side-band protocols have become associated with NFS. This section does not cite any sources.
The client machine requests access to exported data, typically by issuing a mount command. Two competing groups developed over fundamental differences in the two remote procedure call systems. T’s UNIX System V Release 4. ONC RPC protocols and could extend ONC RPC. Later, Sun and ISOC reached a similar agreement to give ISOC change control over NFS, although writing the contract carefully to exclude NFS version 2 and version 3. Instead, ISOC gained the right to add new versions to the NFS protocol, which resulted in IETF specifying NFS version 4 in 2003. By the 21st century, neither DFS nor AFS had achieved any major commercial success as compared to SMB-CIFS or NFS.
IBM, which had formerly acquired the primary commercial vendor of DFS and AFS, Transarc, donated most of the AFS source code to the free software community in 2000. In January, 2010, Panasas proposed an NFSv4. Design and Implementation of the Sun Network Filesystem”. NFS Version 3 Design and Implementation”.

With Amazon EFS, storage capacity is elastic, growing and shrinking automatically as you add and remove files, so your applications have the storage they need, when they need it. Amazon EFS has a simple web services interface that allows you to create and configure file systems quickly and easily. With Amazon EFS, you pay only for the storage used by your file system and there is no minimum fee or setup cost. Costs related to Provisioned Throughput are determined by the throughput values you specify. For more information, see Amazon EFS Pricing.
The service is designed to be highly scalable, highly available, and highly durable. Amazon EFS file systems store data and metadata across multiple Availability Zones in an AWS Region. EFS file systems can grow to petabyte scale, drive high levels of throughput, and allow massively parallel access from Amazon EC2 instances to your data. Amazon EFS provides file system access semantics, such as strong data consistency and file locking. For more information, see Data Consistency in Amazon EFS. Amazon EFS supports two forms of encryption for file systems, encryption in transit and encryption at rest. You can enable encryption at rest when creating an Amazon EFS file system.
If you do, all your data and metadata is encrypted. You can enable encryption in transit when you mount the file system. For more information, see Encrypting Data and Metadata in EFS. Amazon EFS is designed to provide the throughput, IOPS, and low latency needed for a broad range of workloads. The default general purpose performance mode is ideal for latency-sensitive use cases, like web serving environments, content management systems, home directories, and general file serving. O mode can scale to higher levels of aggregate throughput and operations per second with a tradeoff of slightly higher latencies for file operations.
Using the default Bursting Throughput mode, throughput scales as your file system grows. Using Provisioned Throughput mode, you can specify the throughput of your file system independent of the amount of data stored. For more information, see Amazon EFS Performance. Amazon EC2 instances is not supported. Are You a First-Time User of Amazon EFS? For an Amazon EFS product and pricing overview, see Amazon EFS.

Alternatively, the missing information could be added to the various existing FAT file system types chapters. The table contains entries for each cluster, a contiguous area of disk storage. Originally designed as an 8-bit file system, the maximum number of clusters has been significantly increased as disk drives have evolved, and so the number of bits used to identify each cluster has grown. FAT offers reasonably good performance and robustness, even in very light-weight implementations.
FAT was also commonly used on hard disks throughout the DOS and Windows 9x eras, but its use on hard drives has declined since the introduction of Windows XP, which primarily uses the newer NTFS. Due to the widespread use of FAT-formatted media, many operating systems provide support for FAT through official or third-party file system handlers. NT-based versions of Windows, since the exact specification is a trade secret of Microsoft. The DCF file system adopted by almost all digital cameras since 1998 defines a logical file system with 8. 3 filenames and makes the use of either FAT12, FAT16, FAT32 or exFAT mandatory for its physical layer in order to maximize platform interoperability. Hidden FAT filesystems are also used in the UEFI boot partition on modern PC’s where the UEFI specification requires compliant firmware to be capable of reading FAT12, FAT16 and FAT32 compliant partitions.
Technically, the term “FAT file system” refers to all three major variants of the file system, FAT12, FAT16 and FAT32, and most parties clearly distinguish between them where necessary. In contrast to this, Microsoft typically no longer distinguishes between all three of them since the introduction of FAT32, and refers to both FAT12 and FAT16 as “FAT”, whereas “FAT32” gets treated specially in dialog boxes and documentation. Another common cause of confusion exists within the group of FAT16 file systems, since the term “FAT16” refers to both, either the whole group of FAT file systems with 16-bit wide cluster entries, or specifically only the original implementation of it with 16-bit sector entries, when it becomes necessary to differentiate between the original and the later implementation. Yet another cause for misconceptions stems from some apparent redundancy and possible ambiguity in the definition of FAT volumes. Between April and August 1980, while borrowing the FAT concept for SCP’s own 8086 operating system QDOS 0.

The disk’s size was stored and calculated as a 16-bit count of sectors, which limited the size to 32 MiB for a logical sector size of 512 bytes. FAT12 was used by several manufacturers with different physical formats, but a typical floppy disk at the time was 5. By convention, all the control structures were organized to fit inside the first track, thus avoiding head movement during read and write operations, although this varied depending on the manufacturer and physical format of the disk. 0, could prevent the disk from being usable. The DOS formatting tool rejected such disks completely. 0 directory entries included only one date, the last modified date. 1 added the last modified time.
At this time, DOS did not support a hierarchical file system, which was still acceptable, given that the number of files on a disk was typically not more than a few dozen. The PC XT was the first PC with a hard drive from IBM, and PC DOS 2. The fixed assumption of 8 sectors per clusters on hard disks practically limited the maximum partition size to 16 MiB for 512 byte sectors and 4 KiB clusters. 0 introduced support for high-density 1. 15 sectors per track, hence more space for the FATs.
FAT12 remains in use on all common floppy disks, including 1. On August 14, 1984, IBM released the PC AT, which featured a 20 MiB hard disk and PC DOS 3. With the initial implementation of FAT16 not actually providing for larger partition sizes than FAT12, the early benefit of FAT16 was to enable the use of smaller clusters, making disk usage more efficient, particularly for large numbers of files only a few hundred bytes in size. 0 and higher formatted all 16 MiB-32 MiB partitions in the FAT16 format, a 20 MiB hard disk formatted under MS-DOS 3. 0 was not accessible by the older MS-DOS 2. 0 was able to access 16 MiB-32 MiB FAT12 partitions.
PC DOS did not provide means to take advantage of the extra storage, several manufacturers developed their own FAT variants to address the problem in their MS-DOS OEM issues. Other vendors worked around the volume size limits imposed by the 16-bit sector entries and arithmetics by increasing the size of the sectors the file system dealt with, thereby blowing up dimensions. ROM-BIOS INT 13H or the disk drive hardware. The DOS-BIOS or System BIOS would then combine multiple physical sectors into logical sectors for the file system to work with.
