JVM Virtual Memory attributes

Use the JVM Address Space attributes to view the summarized information of the address space memory in use by the specific JVM. Attributes are provided for 24-bit, 31-bit and 64-bit virtual storage. This table replaces ADDRMEM in V610.

Managed System Identifies a collection of the Java Virtual Machines that run on the LPAR that is monitored by the JVM Monitor. The value is a text string of up to 32 alphanumeric characters that combines the Collector ID and the SMF ID in the following format: Collector_ID:SMF_ID:JVM.

SMF ID Indicates the System Management Facility (SMF) identifier of the LPAR.

Collector ID Indicates the identifier of a JVM collector instance.

Job Name Indicates the name of the job or started task that is hosting the JVM.

ASID Address Space ID (in hex) of the jobname hosting this Java virtual machine (JVM).

Process ID Indicates the UNIX System Services process ID (PID) of the JVM.

Heap Size Indicates the total size of the Language Environment Heap.

Heap Allocated Indicates the number of bytes that are allocated or used by the JVM.

Heap Free Indicates the number of bytes that are free for use for the JVM.

24-Bit Memory Size The total size of usable virtual memory below the 16MB line in the address space.

24-Bit Memory User The amount of user virtual memory currently allocated below the 16MB line in the address space.

24-Bit Memory Authorized The amount of virtual memory below the 16MB line currently allocated to authorized storage such as SWA,LSQA, subpools 299 and 230.

24-Bit Memory Free The amount of 24-bit virtual memory remaining below the 16MB line in the address space.

24-Bit Memory Used Percent The percentage of 24-bit virtual memory currently allocated below the 16MB line in the address space.

24-Bit Memory Free Percent The percentage of virtual memory remaining below the 16MB line in the address space.

31-Bit Memory Size The total size of usable 31-bit virtual memory above the 16MB line in the address space.

31-Bit Memory User The amount of 31-bit virtual memory allocated to the user region above the 16MB line in the address space.

31-Bit Memory Authorized The amount of authorized 31-bit virtual memory allocated above the 16MB line in the address space.

31-Bit Memory Free The amount of 31-bit virtual memory remaining above the 16MB line in the address space.

31-Bit Memory Used Percent Percentage of extended region allocated.

31-Bit Memory Free Percent Percentage of extended region free.

64-Bit Memory Limit The total size of usable virtual memory above the bar in the address space.

64-Bit Memory Used The size of virtual memory currently allocated above the bar in the address space.

64-Bit Memory Free The size of remaining virtual memory remaining above the bar in the address space.

64-Bit Memory Used Percent The percentage of 64-bit virtual memory currently allocated in the address space.

64-Bit Memory Free Percent The percentage of 64-bit virtual memory remaining in the address space.
