基本要素 最近用户反馈部署在RAC节点1的OGG的抓取进程已经停止运行几天了，希望排查下原因，让其恢复正常。 问题分析步骤一：查看日志 通过info all命令，查看当前抓取进程的状态，如下，状态为ABENDED，这时我们最简单的方式就是查看OGG的错误日志信息，该信息文件名为ggserr.log,我们看下该错误日志里面的相关错误提示，如下：
这里报OGG-01028错误，可以看到提示没明确，找不到/u01/app/oracle/archive2/2_32522_828663513.dbf归档日志，因为我们这里是RAC环境，采用NFS的方式，把2号节点的归档目录挂载到1号节点的/u01/app/oracle/archive2/目录，因此该路径下应该是2号节点的归档日志。 我们查看了目录确实没有，因为是RAC节点，我们在1号节点去看下，发现该日志文件在1号节点，这是由于用户最近几天在做服务器重启，由于VIP的跳跃，导致本来应该归档在2号节点的日志，归档在了1号节点，因此我们只需要把该日志拷贝到2号节点。 解决过程
步骤一：拷贝日志
我们把在1号节点里面所有本应该归档到2号节点的日志，全部拷贝回2号节点，用SCP命令远程拷贝，如下： [oracle@rac01 archive]$ scp2_32* 192.168.30.3:/u01/app/oracle/archive 2_32522_828663513.dbf 100% 10MB 10.0MB/s 00:01 2_32523_828663513.dbf 100% 1024 1.0KB/s 00:00 2_32540_828663513.dbf 100% 51MB 25.4MB/s 00:02 拷贝完后，再次尝试启动抓去进程，正常启动
关键知识点 RAC归档日志的飘移：RAC环境下，由于某个节点意外关闭，其节点上的业务会回退，产生归档日志，但是该节点又无法访问，因此会将回退产生的归档日志生成到其他节点上，这就是常见的归档日志飘移。

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.
