This article will explain in detail how to adjust the aix 5 swap space for everyone. The quality of the article is high, so Xiaobian shares it with you as a reference. I hope you have a certain understanding of relevant knowledge after reading this article.

When PAGE SPACE is high, you can use vmstat and svmon to track it regularly to see what causes memory consumption, and kill unused processes and redundant services. Or you can add SWAP space to mitigate, as shown below.

1. Check the SWAP space size and utilization rate, and find that the default paging logical volume on the first hard disk of rootvg is hd6.

2. Check the characteristics and status of rootvg

3. Check the details of rootvg volume and find that there are 392 remaining PPS, and the size of each PPS is 256M.

According to calculations, SWAP is expanded from the original 24G to 36G, requiring an increase of 48 PPS. The chps -s command allows you to dynamically increase the size of paging space. (To reduce SWAP space, create a temporary boot image pointing to temporary host paging space and a temporary/sbin/rc.boot to ensure that the system can be safely restarted.) Use chps -d command to dynamically reduce the size of paging space. Note: chps -d command prohibits reducing the size of hd6 to less than 32MB or deleting it.)

5. Expanded PPS

6. Expanded capacity check

[root@test usr]# free

Mem: 513980 493640 20340 0 143808 271780

2. Create swap files in the right places

[root@test usr]# mkdir swap

[root@test usr]# cd swap

[root@test swap]# dd if=/dev/zero of=swapfile bs=1024 count=10000

10000+0 records in

10000+0 records out

[root@test swap]# ls -al

total 10024

drwxr-xr-x 2 root root 4096 Jul 28 14:58 .

drwxr-xr-x 19 root root 4096 Jul 28 14:57 ..

-rw-r--r-- 1 root root 10240000 Jul 28 14:58 swapfile

[root@test swap]# mkswap swapfile

3. Activate swap file

[root@test swap]# swapon swapfile

[root@test swap]# free
