JFS or registered system of file is a filesystem 64-bit which is mainly employed in systems of HP-UX. It is a filing system newspaper which was created by IBM. JFS ensures the uniformity of partition by employing basic technologies of data-notation. If your HP-UX of the operating system obtains broken, JFS can reconstitute the uniformity by the process of implementation of �logredo� which reaches the information which is stored in the file of consignment of JFS.
JFS is a byte-level and a filesystem based by notation which is employed for high efficiency and the systems conceived to treat the movements as of their appearance. Robust and extensible, its advantages above the independent filesystems are its high efficiency, fast possibilities of restarting and restoration of system at one coherent period of state in little time.
Characteristics of design
. The filesystem of JFS was conceived to have entirely integrated the swivelling of the beginning, rather than being added to the existing filesystem.
. It employs the file width-based addressing the structure, with arrangements of attribution of advanced block, so that the effective, extensible and compact structure of creation physically traces logical off-centerings in the files with the address on the unit of hard drive.
. JFS supports basic variable block lengths of system of by-file of 4096,2048,1024 and 512 bytes. It makes it possible to the users to optimize the use of space according to their environment of application.
. The filesystem of JFS dynamically assigns space for the nodes of index of disc by releasing the disk space, when it is not necessary any more. It does not hold any space of the nodes of index of disc when the filesystem is created.
. It follows two different approaches to organize the directories. First is employed for small directories and second is employed for large directories.
Although, JFS is an extremely powerful filesystem but it is not completely sure of corruption and other problems. Sometimes, you can meet that when you begin yourselves computer of HP-UX, it does not initialize and does not post an error message.
This difficulty can arise because of the corruption of filesystem of JFS. It could be due to the attack of virus, with the normal stop of the inaccurate system, the malfunction of software and other similar reasons. In these cases if we do not have postpones and a different system we cannot continue our daily work. All your critical data files become inaccessible and you dealt with critical situations of the loss of data. For the solution this use of problem our services of re-establishment of data.
To overcome these problems, you must choose the re-establishment of data of HP UNIX. It is possible using powerful and advanced applications third, known under the name of software of re-establishment of HP UNIX, such as the stellar software of re-establishment of data of HP UNIX de Phoenix.
The tool for re-establishment of HP UNIX de Phoenix functions in the majority of the situations of loss of data and carries out the HP precise and sure UNIX of re-establishment of data. It supports the re-establishment of JFS 3.0,3.1 and 3.3. The re-establishment of HP UNIX de Phoenix is compatible with HP-UX 10.x, 11 and 11i.
