Hi, all!
I deploy Oracle 19C inside LXC container for self study.
Oracle 19C woks well, but when I try install Examples Databases from LINUX.X64_193000_examples.zip I get next warning message
[oracle@ol8-19c examples]$ ./runInstaller
Starting Oracle Universal Installer...
Checking Temp space: must be greater than 415 MB. Actual 151547 MB Passed
Checking swap space: 0 MB available, 150 MB required. Failed <<<<
Checking monitor: must be configured to display at least 256 colors. Actual 16777216 Passed
Some requirement checks failed. You must fulfill these requirements before
continuing with the installation,
Continue? (y/n) [n] n
I attentively read this post Invalid SwapTotal in /proc/meminfo (SwapTotal 0) but did’t understand what and where I must edit the files for fixing this issue.
Bellow host and container configuration

On the host SWAP works correctly

MiB Mem : 15990.2 total, 772.1 free, 9008.1 used, 6210.0 buff/cache
MiB Swap: 8192.0 total, 8190.2 free, 1.8 used. 1404.0 avail Mem
but when I turn LXC container and attach to it
[oracle@ol8-19c examples]$ grep ^Swap /proc/meminfo
SwapCached: 0 kB
SwapTotal: 0 kB
SwapFree: 0 kB
I want test complicated SQL query that can use SWAP in the time of its execution
