Some Linux distributions (e.g. Debian) do not have a tmpfs mounted on /tmp by default; in this case, files under /tmp will be stored in the same file system as /. And on almost all Linux distributions, a tmpfs is mounted on /run/ or /var/run/ to store temporary run-time files such as PID files and Unix domain sockets.
Server data (data for services provided by system). /sys: In some Linux distributions, contains a sysfs virtual filesystem, containing information related to hardware and the operating system. On BSD systems, commonly a symlink to the kernel sources in /usr/src/sys. /tmp: A place for temporary files not expected to survive a reboot.
In Unix and Linux, the global temporary directories are /tmp and /var/tmp. Web browsers periodically write data to the tmp directory during page views and downloads. Typically, /var/tmp is for persistent files (as it may be preserved over reboots), and /tmp is for more temporary files. See Filesystem Hierarchy Standard.
GT.M is a high-throughput key–value database engine optimized for transaction processing. (It is a type also referred to as "schema-less", "schema-free", or "NoSQL".)GT.M is also an application development platform and a compiler for the ISO standard M language, also known as MUMPS.
To clear it, use chmod -t /usr/local/tmp or chmod 0777 /usr/local/tmp (the latter will also reset the tmp directory to standard permissions). In Unix symbolic file system permission notation , the sticky bit is represented either by the letter t or T in the final character-place depending on whether the execution bit for the others category is ...
Before an Oracle database changes data in a datafile it writes changes to the redo log. If something happens to one of the datafiles, a recovery procedure can restore a backed-up datafile and then replay the redo written since backup-time; this brings the datafile to the state it had before it became unavailable.
The name is a three-letter acronym for DataBase Manager, and can also refer to the family of database engines with APIs and features derived from the original dbm. The dbm library stores arbitrary data by use of a single key (a primary key) in fixed-size buckets and uses hashing techniques to enable fast retrieval of the data by key.
Rdb featured one of the first cost-based optimizers, and after acquisition Oracle introduced a cost-based optimizer in its regular Oracle RDBMS product. On March 22, 2011, Oracle announced it had decided to end all software development on the Itanium , and that Oracle Rdb 7.3 would be the last major version released by Oracle.
