Linux下Oracle 10g的安装
一、实验环境:虚拟机版本号:Workstation 6.5-7.0 virtual machineRedhat版本号:Red Hat Enterprise Linux Server release 5.4
一、实验环境:
虚拟机版本号:Workstation 6.5-7.0 virtual machine
RedHat版本号:Red Hat Enterprise Linux Server release 5.4 (Tikanga)
内核版本号:2.6.18-164.el5
以root用户登录linux系统。默认语言为英语。
Oracle 10g软件包。解压后负责到系统根目录下。
建立本地yum库,挂载光盘镜像文件。
三块磁盘sda、sdb、sdc,sdb1挂载到u01目录下,sdc1挂载到u02目录下。
二、预安装步骤:
本次试验的步骤依据Oracle官方网站提供的文档而做,,有个别步骤可以省略。
在linux下,安装Oracle时对系统的要求有点高,安装前需要对系统进行检查。
1、 检查物理内存和虚拟内存,物理内存至少为1G ,虚拟内存为物理内存的2倍。
(当物理内存小于2G时,虚拟内存是物理内存的2倍;物理内存大于2G时,虚拟内存在此基础加2即可)
物理内存
基本 - 512MB推荐 - 1024MB
内存交换分区相对于物理内存的比例
物理内存1024MB~2048MB - 200%
物理内存2049MB~8192MB - 100%
物理内存大于8192MB - 75%
2、检查tmp目录的大小。
/tmp目录所在的分区至少要有400MB空闲磁盘空间。
根据安装类型,安装Oracle服务器软件的分区至少要有1.5GB到3.5GB的空闲磁盘空间。
1.2GB磁盘空间用于数据库预配置文件系统存储(可选)
3、修改/etc/issue文件,将版本号改为4.4,目前Oracle官方只在5.0以下的版本上测试过。由于在后面安装Oracle时,会检查系统版本号,为了避免检测通不过,最好修改为4.4,修改后查看信息如图:
可以通过执行uname –r来查看内核版本号。

The retention period of Oracle database logs depends on the log type and configuration, including: Redo logs: determined by the maximum size configured with the "LOG_ARCHIVE_DEST" parameter. Archived redo logs: Determined by the maximum size configured by the "DB_RECOVERY_FILE_DEST_SIZE" parameter. Online redo logs: not archived, lost when the database is restarted, and the retention period is consistent with the instance running time. Audit log: Configured by the "AUDIT_TRAIL" parameter, retained for 30 days by default.

The amount of memory required by Oracle depends on database size, activity level, and required performance level: for storing data buffers, index buffers, executing SQL statements, and managing the data dictionary cache. The exact amount is affected by database size, activity level, and required performance level. Best practices include setting the appropriate SGA size, sizing SGA components, using AMM, and monitoring memory usage.

Oracle database server hardware configuration requirements: Processor: multi-core, with a main frequency of at least 2.5 GHz. For large databases, 32 cores or more are recommended. Memory: At least 8GB for small databases, 16-64GB for medium sizes, up to 512GB or more for large databases or heavy workloads. Storage: SSD or NVMe disks, RAID arrays for redundancy and performance. Network: High-speed network (10GbE or higher), dedicated network card, low-latency network. Others: Stable power supply, redundant components, compatible operating system and software, heat dissipation and cooling system.

To create a scheduled task in Oracle that executes once a day, you need to perform the following three steps: Create a job. Add a subjob to the job and set its schedule expression to "INTERVAL 1 DAY". Enable the job.

The amount of memory required for an Oracle database depends on the database size, workload type, and number of concurrent users. General recommendations: Small databases: 16-32 GB, Medium databases: 32-64 GB, Large databases: 64 GB or more. Other factors to consider include database version, memory optimization options, virtualization, and best practices (monitor memory usage, adjust allocations).

Oracle Database memory requirements depend on the following factors: database size, number of active users, concurrent queries, enabled features, and system hardware configuration. Steps in determining memory requirements include determining database size, estimating the number of active users, understanding concurrent queries, considering enabled features, and examining system hardware configuration.

How to use MySQLi to establish a database connection in PHP: Include MySQLi extension (require_once) Create connection function (functionconnect_to_db) Call connection function ($conn=connect_to_db()) Execute query ($result=$conn->query()) Close connection ( $conn->close())

Oracle listeners are used to manage client connection requests. Startup steps include: Log in to the Oracle instance. Find the listener configuration. Use the lsnrctl start command to start the listener. Use the lsnrctl status command to verify startup.
