• display process memory heap address
• display process memory heap size
display process memory heap
Use display process memory heap to display heap memory usage for a user process.
Syntax
MSR2000/MSR3000:
display process memory heap job job-id [ verbose ]
MSR4000:
display process memory heap job job-id [ verbose ] [ slot slot-number [ cpu cpu-number ] ]

Parameters
job job-id: Specifies a user process by its job ID, in the range of 1 to 2147483647.
verbose: Displays detailed information. If you do not specify this keyword, the command displays brief
information.
slot slot-number: Specifies a card by its slot number. If you do not specify this option, the command
displays heap memory usage for the user process on the active MPU. (MSR4000.)
cpu cpu-number: Specifies a CPU by its number.
Usage guidelines
Heap memory comprises fixed-sized blocks such as 16-byte or 64-byte blocks. It stores data and
variables used by the user process. When a user process starts, the system dynamically allocates heap
memory to the process.
Each memory block has an address represented in hexadecimal format, which can be used to access the
memory block. You can view memory block addresses by using the display process memory heap size
command, and view memory block contents by using the display process memory heap address
command.
Examples
# Display brief information about heap memory usage for the process identified by job ID 148.
<Sysname> display process memory heap job 148
Total virtual memory heap space(in bytes) : 2228224
Total physical memory heap space(in bytes) : 262144
Total allocated memory(in bytes) : 161576
# Display detailed information about heap memory usage for the process identified by job ID 148.
