在 Linux x86 上安装 Oracle 数据库 10g步骤:
1、安装Linux及Oracle相关组件;
2、验证系统要求、
创建用户和组、
创建目录、
配置 Linux 内核参数、
为 oracle 用户设置 Shell 限制、
oracle 用户的环境变量;
3、安装;
4、排错;
第 1 部分:安装 Linux(以RHEL3为例)
如果完成了以上步骤,您应该具备 Oracle 10g 所需的所有程序包和更新。您可以执行以下步骤验证您的安装。
所需内核版本:2.4.21-4.EL(这是 RHEL 3 的基本版本附带的内核版本。此内核或更新中提供的任何版本的内核均适用于 Oracle 10g。)
通过运行以下命令检查内核版本:
uname -r
例如:
# uname -r
2.4.21-4.0.1.ELsmp
其他所需程序包的版本(或更高版本):
? gcc-3.2.3-2
? make-3.79
? binutils-2.11
? openmotif-2.2.2-16
? setarch-1.3-1
? compat-gcc-7.3-2.96.122
? compat-gcc-c++-7.3-2.96.122
? compat-libstdc++-7.3-2.96.122
? compat-libstdc++-devel-7.3-2.96.122
? compat-db-4.0.14.5(Oracle 10g 数据库安装指南 中将其列为是必需的,但此处并不需要)
要查看系统上安装了这些程序包的哪些版本,以 root 用户身份运行以下命令:
rpm -q gcc make binutils openmotif setarch compat-db compat-gcc \
compat-gcc-c++ compat-libstdc++ compat-libstdc++-devel
例如:
# rpm -q gcc make binutils openmotif setarch compat-db compat-gcc \
> openmotif compat-gcc-c++ compat-libstdc++ compat-libstdc++-devel
gcc-3.2.3-20
make-3.79.1-17
binutils-2.14.90.0.4-26
openmotif-2.2.2-16
setarch-1.3-1
package compat-db is not installed
compat-gcc-7.3-2.96.122
compat-gcc-c++-7.3-2.96.122
compat-libstdc++-7.3-2.96.122
compat-libstdc++-devel-7.3-2.96.122
请注意,尚未安装 compat-db 程序包。安装过程中可用的任何程序包组均不包含此程序包,因此必须在单独的步骤中安装。如果系统上缺少任何其他程序包版本,,或版本比以上指定的版本旧(compat-db 除外),则可以从 Red Hat Network 下载并安装更新

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.

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.

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.
