- lsps Command. Use this command to see the characteristics of a paging space: # lsps -a.
- svmon Command. Use this command to captures and analyzes a snapshot of virtual memory: # svmon.
- Other commands. You can also use the following commands: # vmstat 1 5. # vmstat 10 10.
Which process is using more memory AIX?
For memory information, we use the command svmon. svmon shows the total usage of physical and paging memory.
How do I create a paging space in AIX?
To make paging space available to your system, you must add and activate the paging space….Using the SMIT interface, type one of the following fast paths on the command line:
- To list your current paging space, type: smit lsps.
- To add paging space, type: smit mkps.
- To activate paging space, type: smit swapon.
How do I check memory on AIX server?
The amount of memory on the computer limits how much memory the database server has available. On AIX you can use a combination of the commands lsdev and lsattr to determine how much memory the computer has. These commands (located in /usr/sbin) are used to display the system devices and their attributes.
What is paging space in AIX?
AIX® uses virtual memory to address more memory than is physically available in the system. A paging space is a type of logical volume with allocated disk space that stores information which is resident in virtual memory but is not currently being accessed.
How do you add swap space in AIX?
Increasing paging space on AIX for WebSphere Network Deployment installation

- Enter this command to increase swap size: # chps -s 8 hd6.
What is computational memory in AIX?
Memory in AIX is managed by VMM, Virtual Memory Manager, that works with pages, a fixed-size block of data. Working storage pages (Computational memory) Permanent storage pages (Non-Computational memory)
How do you find the top memory consuming process?
One of the best commands for looking at memory usage is top. One extremely easy way to see what processes are using the most memory is to start top and then press shift+m to switch the order of the processes shown to rank them by the percentage of memory each is using.

Which command shows the paging space information?
The procedure to check swap space usage and size in Linux is as follows: Open a terminal application. To see swap size in Linux, type the command: swapon -s . You can also refer to the /proc/swaps file to see swap areas in use on Linux.
How do I increase my paging space?
To add more paging space, you must add logical partitions to the system.
How do I turn off paging space in AIX?

Is Aix paging space like swap in Linux?
I get that Paging Space in AIX is actually like SWAP in Linux. In one of my AIX servers at work, i’m actually seeing 99.7% Physical memory being utilized when my application is running(handling quite some data). Most of the time Server is utilizing 95% of Physical memory(RAM).
How is paging space allocated to a process?
Ø All processes started during the boot process are allocated paging space on the default paging space logical volume (hd6). When additional paging space logical volumes are activated, paging space is allocated in a “round robin” manner, in 4KB chunks.
How to trace down process that uses hi=pagimg space?

What is a virtual memory paging space?
Virtual-memory segments are partitioned in units called pages. A paging space is a type of logical volume with allocated disk space that stores information which is resident in virtual memory but is not currently being accessed.
