在linux平台上手动创建数据库(Oracle 10g),安装Oracle软件后,用手动创建数据库可以锻炼自己能力并能够了解数据库创建的全过程,步骤如下:

1、创建Oracle的SID,如果在linux上以dba组中的用户登陆查看主目录中的.bash_profile文件已经设置了此变量就可以不用设置了,如果一个服务器上运行了多个Oracle实例,则还需要设置export ORACLE_SID=myoral

也可以统一在一个文件中设置,然后执行这个文件,让所有关于Oracle的环境变量生效

 

创建一个目录param_myorcl.env

ORACLE_HOME=$ORACLE_HOME   (如果以前创建过Oracle数据库就可以直接利用以前设置的,否则要设置到Oracle安装的目录,可以设置到bin的上层目录)

OACLE_SID=myorcl

PATH=$ORACLE_HOME/bin:$PATH

LD_LIBRARY_PATH=$ORACLE_HOME/bin:$LD_LIBRARY_PATH

TNS_ADMIN=$ORACLE_HOME/network/admin

 

export ORACLE_HOME   ORACLE_SID  PATH LD_LIBRARY_PATH TNS_ADMIN

 

通过执行“ .   ./param_myorcl.env”可以使设置生效,但是这种方式是暂时的,否则可以直接更改.bash_profile使之永久生效

 

2、创建pfile,然后根据pfile创建spfile,利用spfile生成数据库实例(这是Oracle推荐的,虽然也可以利用pfile创建数据库实例)

方法一:如果服务器中已经存在一个数据库,可以通过create pfile from spfile创建pfile文件,再到$ORACLE_HOME/dbs/目录中cp initorcl.ora initmyorcl.ora,这样复制一份后再修改initmyorcl

方法二:strings spfileorcl.ora >initmyorcl.ora(注意要修改,linux上替换命令 : %s/orcl/myorcl/g)

方法三:网上找一份修改,呵呵呵

创建pfile后,检查环境变量是否生效 “env | grep ORA”

如果生效就可以启动Oracle实例了,启动后可以根据pfile创建spfile

         create spfile from pfile;

3、写创建数据库脚本myorcl.sql

spool  on
create database myorcl  
MAXINSTANCES 1 
MAXLOGHISTORY 1 
MAXLOGFILES 5 
MAXLOGMEMBERS 5 
MAXDATAFILES 100 
NATIONAL CHARACTER SET AL16UTF16  
DATAFILE  
'/u01/oracle/oradata/myorcl/system01.dbf' size 100m reuse autoextend on next 1m maxsize unlimited extent management

local  
sysaux datafile  
'/u01/oracle/oradata/myorcl/sysaux01.dbf' size 100m reuse autoextend on next 1m maxsize unlimited  
default temporary tablespace TEMP tempfile  
'/u01/oracle/oradata/myorcl/temp01.dbf' size 20m reuse autoextend on next 640k maxsize unlimited  
undo tablespace UNDOTBS1 datafile  
'/u01/oracle/oradata/myorcl/undo01.dbf' size 20m reuse autoextend on next 5M maxsize unlimited  
logfile  
GROUP 1 ('/u01/oracle/oradata/myorcl/redo1.dbf') size 10m,  
GROUP 2 ('/u01/oracle/oradata/myorcl/redo2.dbf') size 10m,  
GROUP 3 ('/u01/oracle/oradata/myorcl/redo3.d

;

spool off

4、创建数据库

   @$ORACLE_HOME/dbs/myorcl.sql   

 

5、创建数据库数据字典

    spool log1.log

    @?/rdbms/admin/catalog.sql

    @?/rdbms/admin/catproc.sql

    @?/sqlplus/admin/pupbld.sql

MySQL BLOB: how to optimize BLOBs requestsMySQL BLOB: how to optimize BLOBs requestsMay 13, 2025 am 12:03 AM

Optimizing MySQLBLOB requests can be done through the following strategies: 1. Reduce the frequency of BLOB query, use independent requests or delay loading; 2. Select the appropriate BLOB type (such as TINYBLOB); 3. Separate the BLOB data into separate tables; 4. Compress the BLOB data at the application layer; 5. Index the BLOB metadata. These methods can effectively improve performance by combining monitoring, caching and data sharding in actual applications.

Adding Users to MySQL: The Complete TutorialAdding Users to MySQL: The Complete TutorialMay 12, 2025 am 12:14 AM

Mastering the method of adding MySQL users is crucial for database administrators and developers because it ensures the security and access control of the database. 1) Create a new user using the CREATEUSER command, 2) Assign permissions through the GRANT command, 3) Use FLUSHPRIVILEGES to ensure permissions take effect, 4) Regularly audit and clean user accounts to maintain performance and security.

MySQL: String Data Types and Indexing: Best PracticesMySQL: String Data Types and Indexing: Best PracticesMay 12, 2025 am 12:11 AM

Best practices for handling string data types and indexes in MySQL include: 1) Selecting the appropriate string type, such as CHAR for fixed length, VARCHAR for variable length, and TEXT for large text; 2) Be cautious in indexing, avoid over-indexing, and create indexes for common queries; 3) Use prefix indexes and full-text indexes to optimize long string searches; 4) Regularly monitor and optimize indexes to keep indexes small and efficient. Through these methods, we can balance read and write performance and improve database efficiency.
