Maintain Db2 Parameters

You can change most Db2 parameters (ZPARMs) and attributes dynamically through the online panels, through batch jobs, or using z/OS modify commands. You can also use the scheduler task to change certain parameter settings at specified times.

You can change most Db2 parameters (ZPARMs) and attributes dynamically through the online panels, through batch jobs, or using z/OS modify commands. The online panels let you modify DSNZPARM options, DSNHDECP data, and IRLM data. The batch jobs and modify commands let you modify startup and runtime parameters. You can also use the scheduler task to change certain parameter settings at specified times. For example, use the scheduler to resize the buffer pool during prime-time processing and batch processing windows.
