How to query the table ending in oracle database

Table names ending in a specific string can be queried using the ALL_TABLES view and the LIKE operator. The specific steps are: 1. Use the SQL statement SELECTtable_nameFROMall_tablesWHEREtable_nameLIKE'%Specific string'; 2. If it is case-insensitive, use the UPPER function, such as SELECTtable_nameFROMall_tablesWHEREUPPER(table_name)LIKE'%_LOG'.

Solve the problem of Redo log corruption in Oracle database

In the face of the Redo log corruption of Oracle database, four steps should be taken: 1. Assess the degree of corruption, use the ALTERDATABASECLEARLOGFILE or ALTERDATABASEOPENRESETLOGS command, but be careful; 2. Try to repair and use RMAN tools to restore the database from backup; 3. When restoring, you need to evaluate the risk of data loss and communicate with the business department; 4. Preventive measures include regular inspection and maintenance, and establish a sound backup strategy.

Implement master-slave replication and high availability of Oracle databases

Master-slave replication and high availability are implemented in Oracle through DataGuard and GoldenGate to ensure data consistency and system reliability. 1) DataGuard provides physical and logical replication, and configuration commands include ALTERSYSTEMSET and ALTERDATABASE. 2) GoldenGate supports heterogeneous database replication, using ADDEXTRACT and ADDREPLICAT commands. 3) High availability is implemented through OracleRAC and DataGuard. RAC uses the srvctl command to add nodes, and DataGuard fails over through the ALTERDATABASE command.
