create spfile from pfile tips The Oracle SPFILE. The SPFILE is different from the PFILE in that it can not be directly edited. This is because it has a header and footer that contains binary values. Since you can not change a SPFILE directly, Oracle allows you to manage the SPFILE via the alter system command. Also see this spfile example.

Oracle Database 18c PL/SQL Oracle Technology Network Database Database Features PL/SQL. PL/SQL is a procedural language designed specifically to embrace SQL statements within its syntax. PL/SQL program units are compiled by the Oracle Database server and are stored inside the database. And at run-time, both PL/SQL and SQL run within the same server process, bringing optimal efficiency. PL/SQL automatically inherits the robustness, security, and portability of the Oracle Database.

What's an Oracle instance? Different vendors use these terminologies to mean different things. In Oracle-speak, a database is the collection of datafiles on disk. These datafiles belong to your tablespaces. They are also the online redo log files, the parameter file, the password file, and the control files. A database exists on disk and will be there even if you shut down the server and reboot it. But a database is not accessible by itself. You have to sign on to SQL*Plus and issue a STARTUP command.

EMF File Format EMF is a file extension for Enhanced MetaFile, a spool file format used in printing by the Windows operating system. When a print job is sent to the printer, if it is already printing another file, the computer reads the new file and stores it, usually on the hard disk or in memory, for printing at a later time. EMF files may be created and reside in memory or disk space when windows cache s them while waiting on another printing job.

11 Physical Storage Structures Because physical and logical structures are separate, you can manage physical storage of data without affecting access to logical structures. For example, renaming a database file does not rename the tables stored in it. An Oracle database is a set of files that store Oracle data in persistent disk storage. A data file is a physical file on disk that was created by Oracle Database and contains data structures such as tables and indexes. A temp file is a data file that belongs to a temporary tablespace.

Oracle Concepts - initialization parameters init.ora Oracle reads the initialization parameter values from either a PFILE or SPFILE as the database is starting. The parameters tell the Oracle programs how much memory to allocate, where to put files related to the database and the location of existing datafiles. A parameter has a name and a value. In this example, we have a parameter named db_block_size. This parameter tells oracle how big each individual block in the database is (we discussed blocks in an earlier chapter in this book). In this case, each block is 8192 bytes, or 8k, in size.
