Oracle 11gR2 RAC 添加节点
[日期：2012-02-19] 来源：Linux社区 作者：wenhuiqiao [字体：]
1.添加clusterware节点
在已有的节点上
cluvfy stage -pre nodeadd -n node3 [-fixup [-fixupdir fixup_dir]] [-verbose]
--11.2.0.2的安装有BUG，共享磁盘检测总是不成功，所以在确认只有磁盘检测错误，并且在新节点上确定能够访问共磁盘的情况下忽略CHECKS
export IGNORE_PREADDNODE_CHECKS=Y
Grid_home/oui/bin/./addNode.sh -silent "CLUSTER_NEW_NODES={node3}" "CLUSTER_NEW_VIRTUAL_HOSTNAMES={node3-vip}"
cluvfy stage -post nodeadd -n node3 [-verbose]
2.添加INSTANCE
在已有的节点上
Oracle_home/oui/bin/addNode.sh -silent "CLUSTER_NEW_NODES={devdb03}"
Oracle_home/bin/dbca -silent -addInstance -nodeList devdb03 -gdbName devdb -instanceName devdb3 -sysDBAUserName sys -sysDBAPassword oracle

MySQL: String Data Types and CollationsMay 09, 2025 am 12:08 AMThe string data types in MySQL include CHAR, VARCHAR, BINARY, VARBINARY, BLOB, and TEXT. The collations determine the comparison and sorting of strings. 1.CHAR is suitable for fixed-length strings, VARCHAR is suitable for variable-length strings. 2.BINARY and VARBINARY are used for binary data, and BLOB and TEXT are used for large object data. 3. Sorting rules such as utf8mb4_unicode_ci ignores upper and lower case and is suitable for user names; utf8mb4_bin is case sensitive and is suitable for fields that require precise comparison.
MySQL: What length should I use for VARCHARs?May 09, 2025 am 12:06 AMThe best MySQLVARCHAR column length selection should be based on data analysis, consider future growth, evaluate performance impacts, and character set requirements. 1) Analyze the data to determine typical lengths; 2) Reserve future expansion space; 3) Pay attention to the impact of large lengths on performance; 4) Consider the impact of character sets on storage. Through these steps, the efficiency and scalability of the database can be optimized.
