Manual Oracle database creation under RHEL4.5

Source: Internet
Author: User

Platform: RHEL4.5, Oracle10.2.0.1
Plan: db_name = ORCLDB, db_unique_name/ORACLE_SID = WENDING
The above two parameters can also be set to the same, here is the main difference.

1. Set Environment Variables
$ Export ORACLE_BASE =/u01/app/oracle
$ Export ORACLE_HOME = $ ORACLE_BASE/product/10.2.0/db_1
$ Export ORACLE_SID = WENDING

2. Create an initialization parameter file
$ Vi $ ORACLE_HOME/dbs/init $ ORACLE_SID.ora
# The following are required parameters for creating a database:
Control_files = (/orahome/oradata/control1.ctl,/orahome/oradata/control2.ctl,/orahome/oradata/control3.ctl)
Undo_management = AUTO
Undo_tablespace = UNDOTBS1
Db_name = ORCLDB
Db_unique_name = WENDING
DB _ block_size = 8192
Sga_max_size = 320 M
Sga_target = 320 M
# The following are the parameters that need to be set for the general database creation. If this parameter is not set, the default value is used.
Audit_file_dest =/u01/app/oracle/admin/WENDING/adump # default $ ORACLE_HOME/rdbms/adump is not set
Background_dump_dest =/u01/app/oracle/admin/WENDING/bdump # default $ ORACLE_HOME/rdbms/log is not set
Core_dump_dest =/u01/app/oracle/admin/WENDING/cdump # default $ ORACLE_HOME/rdbms/dbs is not set
User_dump_dest =/u01/app/oracle/admin/WENDING/udump # default $ ORACLE_HOME/rdbms/log is not set
Db_domain = LK # null by default when not set
Open_cursors = 1500 # do not set the default value of 50
Processes = 500 # default 40 is not set
Log_archive_dest_1 = 'location =/orahome/arch/wending' # If this parameter is not set, the default value is null. the archive is stored in $ ORACLE_HOME/rdbms/dbs/arch.
Log_archive_format = 'Log _ % t _ % s _ % r. arc' # The default value % t _ % s _ % r. dbf is not set.
Job_queue_processes = 10 # do not set the default value to 0
Undo_retention = 10800 # default 900 is not set
# To enable the audit function, set the following parameters:
Audit_sys_operations = TRUE
Audit_trail = db, extended # Note: if it is converted to a physical standby database in the future, the database cannot be set here; otherwise, the read only mode cannot be enabled for the physical standby database in the future.
Db_recovery_file_dest =/orahome/flash_recovery_area # required in OMF Mode
Db_recovery_file_dest_size = 2G # required for OMF Mode

# If you use OMF to manage database files, you need to set the following parameters:
Db_create_file_dest =/orahome/oradata # automatically create the./{db_name}/datafile directory under this directory.
Db_create_online_log_dest_1 =/orahome/oradata # automatically create the./{db_name}/onlinelog directory under this directory.

3. Create a password file
$ ORACLE_HOME/bin/orapwd file = $ ORACLE_HOME/dbs/orapw $ ORACLE_SID password = iamwangnc force = y

4. Create a directory
$ Rm-rf $ ORACLE_BASE/admin/$ ORACLE_SID
$ Mkdir-p $ ORACLE_BASE/admin/$ ORACLE_SID/adump
Mkdir-p $ ORACLE_BASE/admin/$ ORACLE_SID/bdump
Mkdir-p $ ORACLE_BASE/admin/$ ORACLE_SID/cdump
Mkdir-p $ ORACLE_BASE/admin/$ ORACLE_SID/dpdump
Mkdir-p $ ORACLE_BASE/admin/$ ORACLE_SID/udump
Mkdir-p $ ORACLE_BASE/admin/$ ORACLE_SID/pfile

# If you use OMF to manage database files, you do not need to create the following directory
$ Rm-rf/orahome/oradata/WENDING
Mkdir-p/orahome/oradata/WENDING
$ Rm-rf/orahome/arch/WENDING
Mkdir-p/orahome/arch/WENDING

5. Start the instance and create the database after creating the spfile.
$ Sqlplus '/as sysdba'
SQL> create spfile from pfile; (pfile: $ ORACLE_HOME/dbs/init $ ORACLE_SID.ora is automatically read)
SQL> startup nomount
SQL> create database ORCLDB CONTROLFILE REUSE
MAXINSTANCES 8 MAXDATAFILES 100
MAXLOGHISTORY 1 MAXLOGFILES 16 MAXLOGMEMBERS 5
Character set ZHS16GBK national character set AL16UTF16
Logfile group 1 ('/orahome/oradata/WENDING/redo1.log') size 50 M reuse,
Group 2 ('/orahome/oradata/WENDING/redo2.log') size 50 M reuse,
Group 3 ('/orahome/oradata/WENDING/redo3.log') size 50 M reuse
Datafile '/orahome/oradata/WENDING/system. dbf' size 500 M reuse autoextend on next 10 M maxsize unlimited extent management local
Sysaux datafile '/orahome/oradata/WENDING/sysaux. dbf' size 100 M autoextend on next 10 M maxsize unlimited
Default temporary tablespace temp tempfile '/orahome/oradata/WENDING/temp01.dbf' size 100 M reuse autoextend on next 10 M maxsize unlimited
Undo tablespace undotbs1 datafile '/orahome/oradata/WENDING/undotbs1.dbf' size 100 M reuse autoextend on next 10 M maxsize unlimited
User sys identified by "iamwangnc" user system identified by "iamwangnc ";

You can also consider the following parameters for creating a database:
Set timezone = 'time _ zone_region'
Set timezone = '{+ |-} hh: mm'
FORCE LOGGING
After the database is created, the database is automatically open.
Note: MAXLOGFILES indicates the number of logfile groups that can be created, and MAXLOGMEMBERS indicates the number of members in each group. If the control file exceeded before 10.2, it is unnecessary in 10.2. Oracle automatically updates the two parameter values in the control file and does not need to recreate the control file! In oracle10g, the default value of MAXLOGFILES is 16, MAXLOGMEMBERS is 3, but cannot exceed 5 when new, or a ORA-02249 error occurs.
In addition, if you want to obtain the specified MAXxxx parameters in the future, you can use the dump control file to obtain: alter database backup controlfile to trace;

If you use OMF to manage database files, create a database using the following methods:
SQL> create database ORCLDB
Controlfile reuse ARCHIVELOG
Character set ZHS16GBK national character set AL16UTF16
Undo tablespace undotbs1
Default temporary tablespace temp;
Or you can create a character set in the minimum mode (the character set is automatically specified according to the operating system, and the default value is used for other parameters ):
SQL> create database ORCLDB;
