1 创建虚拟机
这里我们创建2台虚拟机作为集群里的2个节点。
通过Oracle Virtual Machine Template创建虚拟机 RAC1_13 和 RAC2_13.
虚拟机的内存至少为 1G
每台机器应创建 2 块虚拟网卡,如下图所示:
Select |
Virtual Network Interface Name |
Virtual Network Interface MAC Address |
Xen Bridge |
Status |
Network Interface |
Select |
VIF0 |
00:16:3E:2A:69:C6 |
xenbr0 |

netfront |
Select |
VIF1 |
00:16:3E:37:80:7C |
xenbr1 |

netfront |
作为RAC节点的虚拟机的OS 版本应一致,这里我们都选择 Oracle Enterprise Linux Release 4 Update 5.
创建完毕,“Power On”所有的节点。
2 安装Clusterware前的准备
2.1 检查系统硬件环境 (在所有节点上)
系统硬件条件至少应满足
1G RAM
# grep MemTotal /proc/meminfo
Swap 1.5G
# grep SwapTotal /proc/meminfo
/tmp >400MB
# df -k /tmp
650MB的磁盘空间作为Oracle Clusterware home
1G磁盘空间用来放Oracle Clusterware file
如果考虑冗余的话,需要再增加分区
至少4G磁盘空间作为Oracle Database home
虚拟机的磁盘空间不够的话,可以通过增加虚拟磁盘的方法解决
2.2 配置和检查系统软件环境 (在所有节点上)
检查系统是否已经安装以下的包
binutils-2.15.92.0.2-18 elfutils-libelf-0.97-5 elfutils-libelf-devel-0.97.5 glibc-2.3.9.4-2.19 glibc-common-2.3.9.4-2.19 glibc-devel-2.3.9.4-2.19 gcc-3.4.5-2 gcc-c++-3.4.5-2 libaio-devel-0.3.105-2 libaio-0.3.105-2 libgcc-3.4.5 libstdc++-3.4.5-2 libstdc++-devel-3.4.5-2 make-3.80-5 |
通过模板创建的虚拟机,OS可能没有安装全部需要的包。
用户在安装前请参照Oracle官方文档检查系统是否已经安装所需的包。

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 Oracle database startup sequence is: 1. Check the preconditions; 2. Start the listener; 3. Start the database instance; 4. Wait for the database to open; 5. Connect to the database; 6. Verify the database status; 7. Enable the service (if necessary ); 8. Test the connection.

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.

To find the number of occurrences of a character in Oracle, perform the following steps: Get the total length of a string; Get the length of the substring in which a character occurs; Count the number of occurrences of a character by subtracting the substring length from the total length.

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.

Oracle can read dbf files through the following steps: create an external table and reference the dbf file; query the external table to retrieve data; import the data into the Oracle table.

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).

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.
