Allocating additional server memory
Allocate more memory on the server if there are indications that your server is low on memory resources. Refer to your operating system’s documentation for information about adding memory.
Tip: The amount of memory that Db2
uses might contribute to reports that show that the operating system is out of memory. You can limit
the amount of memory that Db2 uses by
including the DBMEMPERCENT option. The DBMEMPERCENT option
specifies the percentage of virtual address space that is dedicated to the database manager
processes.
Complete the following actions to allocate additional storage resources for the server:
Ensure that there is sufficient paging space. You
can also use SMIT (System Management Interface Tool) to determine
if the number of applications is causing a memory shortage.
The preferred method of solving a low memory
condition is to add physical memory to the system. Otherwise, from
the control panel, increase the amount of the virtual storage by running
the system applet and increasing the total paging file size.
