Creation of TABLESPACE on ORACLE 10g..


Concept:

  • An Oracle database consists of one or more logical storage units called tablespaces, which collectively store all of the database's data.

  • Each tablespace in an Oracle database consists of one or more files called datafiles, which are physical structures that conform to the operating system in which Oracle is running.

  • A database's data is collectively stored in the datafiles that constitute each tablespace of the database. For example, the simplest Oracle database would have one tablespace and one datafile. Another database can have three tablespaces, each consisting of two datafiles (for a total of six datafiles).


SYNTAX:-

CREATE SMALLFILE/BIGFILE TABLESPACE <TSPACE_NAME>
DATAFILE '<PHYSICAL_LOCATION\FILE_NAME>'
SIZE <FILE_SIZE>[M/K/G/T]
AUTOEXTEND ON/OFF {Note: If On}
                        NEXT <INCREASE_SIZE>[M/K/G/T]  MAXSIZE  <FILE_SIZE>[M/K/G/T]

LOGGING EXTENT MANAGEMENT
LOCAL SEGMENT SPACE MANAGEMENT AUTO 



EXAMPLE:-

CREATE SMALLFILE TABLESPACE "ECHO_HOME_DB"
DATAFILE 'H:\APP\ECLIPSE\ORADATA\ORCL\ECHO_HOME_DB_FILE'
SIZE 50M
AUTOEXTEND ON
NEXT 1M
MAXSIZE 500M
LOGGING EXTENT MANAGEMENT
LOCAL SEGMENT SPACE MANAGEMENT AUTO

Using GREP in UNIX

How To Use grep Command In Linux / UNIX by  VIVEK GITE  on  AUGUST 2, 2007  ·  147 COMMENTS H ow do I use grep command in Linux? grep command searches the given file for lines containing a match to the given strings or words. By default, grep prints the matching lines. Use grep to search for lines of text that match one or many regular expressions, and outputs only the matching lines. The name, "grep", derives from the command used to perform a similar operation, using the Unix/Linux text editor ed: g/re/p grep command syntax grep 'word' filename grep 'string1 string2' filename cat otherfile | grep 'something' command | grep 'something' Use grep to search file Search /etc/passwd for boo user: $ grep boo /etc/passwd You can force grep to ignore word case i.e match boo, Boo, BOO and all other combination with -i option: $ grep -i "boo" /etc/passwd Use grep recursively You can search recursively i.e. read all files under each ...
