Guidance: I. Introduction: A rollback segment is a part of a database that records information about database changes. Use this information to achieve database read consistency and restoration. If the rollback segment fails, the database cannot be started normally, resulting in database paralysis and the user cannot read or write data. If the rollback segment can be eliminated, the actual data of the user will not be affected. I recently encountered a problem in my practical work: the user de

A large number of Redis servers have the risk of SSH permission theftGuideRedis servers that completely ignore Security features have been plagued by various Security risks since they were created. Risk Based Security (RBS) recently, we found that 6338 compromised Redis servers, Redis, are NOSQL databases that store data in key-value pairs in the memory.
