Handling character sets and collations issues in MySQL
Article Introduction：Character set and sorting rules issues are common when cross-platform migration or multi-person development, resulting in garbled code or inconsistent query. There are three core solutions: First, check and unify the character set of database, table, and fields to utf8mb4, view through SHOWCREATEDATABASE/TABLE, and modify it with ALTER statement; second, specify the utf8mb4 character set when the client connects, and set it in connection parameters or execute SETNAMES; third, select the sorting rules reasonably, and recommend using utf8mb4_unicode_ci to ensure the accuracy of comparison and sorting, and specify or modify it through ALTER when building the library and table.

How can you clone an Oracle database using RMAN or other methods?
Article Introduction：Methods to cloning Oracle databases include using RMANDuplicate, manual recovery of cold backups, file system snapshots or storage-level replication, and DataPump logical cloning. 1. RMANDuplicate supports replication from active databases or backups, and requires configuration of auxiliary instances and execution of DUPLICATE commands; 2. The cold backup method requires closing the source library and copying files, which is suitable for controllable environments but requires downtime; 3. Storage snapshots are suitable for enterprise-level storage systems, which are fast but depend on infrastructure; 4. DataPump is used for logical hierarchical replication, which is suitable for migration of specific modes or tables. Each method has its applicable scenarios and limitations.
