在Linux平台上手动创建数据库(Oracle 10g)
安装完Oracle软件后,不使用dbca创建数据库,而手动创建数据库,主要目的是了解数据库创建
的过程中主要进行了那些操作。
1.首先设置要创建的ORACLE的SID,如果在.bash_profile文件里设置里该变量,就不用设置了。
$echo $ORACEL_SID
ora10
设置oracle用户环境文件
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
# User specific environment and startup programs
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/10.2.0/db_1
export ORACLE_SID=ora10
export ORACLE_TERM=xterm
export PATH=$ORACLE_HOME/bin:/usr/sbin:$PATH
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
export CLASSPATH=$ORACLE_HOME/jre:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib
unset USERNAME
"~/.bash_profile" 18L, 469C
如果没有设置,,就手动设置,如果一个服务器上要运行多个ORACLE实例,也需要手动设置。
export ORACLE_SID=ora10
2. 创建需要的诊断目录,这些目录都是ORACLE进程遇到错误或用户手动TRACE时需要的。
mkdir -p /oradata/admin/ora10/adump
mkdir -p /oradata/admin/ora10/bdump
mkdir -p /oradata/admin/ora10/cdump
mkdir -p /oradata/admin/ora10/udump
mkdir -p /oradata/admin/ora10/pfile
创建oracle的数据文件目录
mkdir -p /oradata/ora10
3. 创建ORACLE的参数文件$ORACLE_HOME/dbs/initora10.ora 内容如下:
aq_tm_processes=0
audit_file_dest=/oradata/admin/ora10/adump
background_dump_dest=/oradata/admin/ora10/bdump
compatible=10.2.0.1.0
control_files=/oradata/ora10/control01.ctl, /oradata/ora10/control02.ctl,
/oradata/ora10/control03.ctl
core_dump_dest=/oradata/admin/ora10/cdump
db_block_size=8192
db_domain=""
db_file_multiblock_read_count=16
db_name=ora10
instance_name=ora10
dispatchers="(PROTOCOL=TCP) (SERVICE=mydbXDB)"
job_queue_processes=10
nls_length_semantics=BYTE
open_cursors=300
pga_aggregate_target=94371840
processes=150
remote_login_passwordfile=EXCLUSIVE
resource_manager_plan=""
sessions=170
sga_target=285212672
undo_management=AUTO
undo_retention=900
undo_tablespace=UNDOTBS1
user_dump_dest=/oradata/admin/ora10/udump
4.创建密码文件
orapwd file=$ORACLE_HOME/dbs/orapwora10 password=oracle entries=5 force=y
5.创建oracle的建库脚本 createdb.sql,内容如下:
create database ora10
MAXINSTANCES 1
MAXLOGHISTORY 1
MAXLOGFILES 5
MAXLOGMEMBERS 5
MAXDATAFILES 100
DATAFILE
'/oradata/ora10/system01.dbf' size 100m reuse autoextend on next 1m maxsize
unlimited extent management local
sysaux datafile
'/oradata/ora10/sysaux01.dbf' size 100m reuse autoextend on next 1m maxsize
unlimited
default temporary tablespace TEMP tempfile
'/oradata/ora10/temp01.dbf' size 20m reuse autoextend on next 640k maxsize unlimited
undo tablespace UNDOTBS1 datafile
'/oradata/ora10/undo01.dbf' size 20m reuse autoextend on next 5M maxsize unlimited
logfile
GROUP 1 ('/oradata/ora10/redo1.dbf') size 10m,
GROUP 2 ('/oradata/ora10/redo2.dbf') size 10m,
GROUP 3 ('/oradata/ora10/redo3.dbf') size 10m
CHARACTER SET ZHS16GBK
NATIONAL CHARACTER SET AL16UTF16
;
启动数据库到nomount状态,执行创建数据库脚本 createdb.sql
6.数据库创建完成后,再创建ORACLE的数据字典。
sys用户登录
SQL>@?/rdbms/admin/catalog.sql
SQL>@?/rdbms/admin/catproc.sql
SQL>@?/rdbms/admin/catexp.sql
7.建立监听和本地服务名
listener.ora
到此ORACLE手动创建过程就完成了

MySQL uses a GPL license. 1) The GPL license allows the free use, modification and distribution of MySQL, but the modified distribution must comply with GPL. 2) Commercial licenses can avoid public modifications and are suitable for commercial applications that require confidentiality.

The situations when choosing InnoDB instead of MyISAM include: 1) transaction support, 2) high concurrency environment, 3) high data consistency; conversely, the situation when choosing MyISAM includes: 1) mainly read operations, 2) no transaction support is required. InnoDB is suitable for applications that require high data consistency and transaction processing, such as e-commerce platforms, while MyISAM is suitable for read-intensive and transaction-free applications such as blog systems.

In MySQL, the function of foreign keys is to establish the relationship between tables and ensure the consistency and integrity of the data. Foreign keys maintain the effectiveness of data through reference integrity checks and cascading operations. Pay attention to performance optimization and avoid common errors when using them.

There are four main index types in MySQL: B-Tree index, hash index, full-text index and spatial index. 1.B-Tree index is suitable for range query, sorting and grouping, and is suitable for creation on the name column of the employees table. 2. Hash index is suitable for equivalent queries and is suitable for creation on the id column of the hash_table table of the MEMORY storage engine. 3. Full text index is used for text search, suitable for creation on the content column of the articles table. 4. Spatial index is used for geospatial query, suitable for creation on geom columns of locations table.

The main difference between MySQL and SQLite is the design concept and usage scenarios: 1. MySQL is suitable for large applications and enterprise-level solutions, supporting high performance and high concurrency; 2. SQLite is suitable for mobile applications and desktop software, lightweight and easy to embed.

Indexes in MySQL are an ordered structure of one or more columns in a database table, used to speed up data retrieval. 1) Indexes improve query speed by reducing the amount of scanned data. 2) B-Tree index uses a balanced tree structure, which is suitable for range query and sorting. 3) Use CREATEINDEX statements to create indexes, such as CREATEINDEXidx_customer_idONorders(customer_id). 4) Composite indexes can optimize multi-column queries, such as CREATEINDEXidx_customer_orderONorders(customer_id,order_date). 5) Use EXPLAIN to analyze query plans and avoid

Using transactions in MySQL ensures data consistency. 1) Start the transaction through STARTTRANSACTION, and then execute SQL operations and submit it with COMMIT or ROLLBACK. 2) Use SAVEPOINT to set a save point to allow partial rollback. 3) Performance optimization suggestions include shortening transaction time, avoiding large-scale queries and using isolation levels reasonably.
