Oracle 11gR2 RAC添加新节点错误之--IP子网掩码
系统环境：
操作系统：RedHat EL5
Cluster： Oracle GI(Grid Infrastructure)
Oracle： Oracle 11.2.0.1.0
如图所示：RAC 系统架构
对于Oracle 11G构建RAC首先需要构建GI(Grid Infrastructure)的架构
案例分析：
在Oracle 11gR2 RAC在添加新节点时，添加grid，在node3上执行root.sh时，出现以下错误：

How long will Oracle database logs be kept?
May 10, 2024 am 03:27 AM
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 order of the oracle database startup steps is
May 10, 2024 am 01:48 AM

How much memory does oracle require?
May 10, 2024 am 04:12 AM
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.
How to see the number of occurrences of a certain character in Oracle
May 09, 2024 pm 09:33 PM

Oracle database server hardware configuration requirements
May 10, 2024 am 04:00 AM
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.
