Full Discussion: Add additional swap place on AIX server
Operating Systems AIX Add additional swap place on AIX server Post 302971432 by agent.kgb on Wednesday 20th of April 2016 05:27:54 AM

zaxxon,

not every segment in AIX memory has a corresponding process.

The real command to look, what lays in paging space is something like:

Code:
svmon -S -O sortseg=pgsp -t 20

-S shows all memory segments, -O sortseg=pgsp sorts them, showing first the segments which have most pages in the paging space, -t 20 shows only first 20 segments.

This is an example from a system, which pages right now:
Code:
$ lsps -a
Page Space      Physical Volume   Volume Group    Size %Used Active Auto  Type Chksum
hd6             hdisk0            rootvg        8192MB    24   yes   yes    lv     0
$ svmon -S -O sortseg=pgsp -t 20
Unit: page

  884951         - work mmap paging                 sm   8192     0 2186    8192
  8c1b3a         - work                             sm     48     4 2082    2101
  825965         - work                              m   4096     0  124    4096

As you see, all the segments are "work" segments and some of them has "long" Vsids (virtual segment IDs), such as 8f61ff, but some of them has "short" Vsid, such as 8000. Those with long IDs are probably associated with some processes. You can look at them using the following command:

Code:
$ svmon -S 8f61ff -lrj

    Vsid      Esid Type Description              PSize  Inuse   Pin Pgsp Virtual
  8f61ff         - work mmap paging                  s      0     0 65024   65024
                                                     m      0     0    0       0
                   Addr Range: 0..65534
                   pid(s)=12058694

The last string contains pid, which you can then find with ps -ef:

Code:
$ ps -ef | grep [1]2058694
    root 12058694 16973956   0   Feb 01      - 320:07 /opt/ibm/node/bin/node /kibana/src/cli

If you look at a segment with short Vsid, you will not see any pid:

Code:
$ svmon -S 8000 -lrj

    Vsid      Esid Type Description              PSize  Inuse   Pin Pgsp Virtual
    8000         - work page table area              s   6916    43 6873    6916
                   Addr Range: 0..8703
                   System segment

It is a system segment and it has no corresponding process. Sometimes they can grow very big and in this case it is not an application problem, but server's configuration problem.
