Brief introduction UNIX and Linux users typically check the processes running on their servers to perform problem analysis and to check the resources consumed in the server. This information is useful not only for administrators who perform issues and resource analysis, but also for those who develop high availability and failover scripts that monitor the DB2 process to determine when operations such as database restarts or server failover are require

Except those who do not know what paging is, most people think of a word called LIMIT. Unfortunately, DB2 does not support this keyword, so how do I write the DB2 paging query? As long as you have learned OLAP functions, paging query is very simple.

From the perspective of the lock granularity (the size of the Lock Object), Oracle DML locks have two levels: Row-level locks and table-level locks.3.1 Oracle TX locks (Row-level locks and transaction locks)Many technical staff who are not familiar with Oracle may think that each TX lock represents a blocked data row. The original meaning of TX is Transaction. When a Transaction executes data changes (Insert, Update, Delete) for the first time or uses
