On Solaris 11.4 NTP does update the time after boot.
By default this can take a few minutes, because the NTP client
waits for a few reply’s of the NTP servers.
To update the time quickly it is recommended to use the ‘burst iburst’
flags in the ntp.conf
server <ntpserverip> burst iburst
Using this configuration NTP adjusts the time a few seconds after start.
This is an important configuration if you start your apps or databases automatically.
Below is the error message I received while I was trying to install Oracle Database 19c on Oracle Linux 7.
PRVF-7573 : Sufficient swap size is not available on node
As per my error on the installer screen I needed 16GB of SWAP space where as my system has just 4GB. So I need to add a swap file for the installation to continue.
Below steps will outline the steps for the same.
dd if=/dev/sdb of=/tmp/swap01 bs=1K count=16M
chmod 600 /tmp/swap01
mkswap /tmp/swap01
swapon /tmp/swap01
Make sure the bs (*) count is equal to your required SWAP space. Also, the /dev/sdb has enough storage as needed
Tried to load a firmware package from solaris 10 to the Service Processor on a T5240 machine and it failed with status = 2. Most of the time the issue will be due to the service processor being slow, having too many stale connections. There might be few other things which contributes to the issue. Check the solutions below, if this is not the issue you are seeing then you will have to contact oracle support with the snapshot of ilom, server patch level and the commands you are running.

Now try to load the firmware from the solaris operating system to the service processor.
#cd /var/tmp/147310-08 # ./sysfwdownload Sun_System_Firmware-7_4_5-SPARC_Enterprise_T5140+T5240.pkg
Example 1:
You want to find files between specific time frame and move them to different directory. You can use the -newer or -newmt option with find command.
In this below example I am creating 2 dummy files with different timestamp and moving any files found between those time frames are moved to directory /var/tmp/Archive.
# touch -t 201310040000 first # touch -t 201410040000 last # find . -newer first ! -newer last -type f -exec mv {} /var/tmp/Archive;
Example 2:
In this example, I am listing files between Oct 04 2013 and Oct 04 2014.
Sed command is for replacing dot ‘.’ with blank space before the file name.
#find . -newermt “2013-10-04 00:00:00” ! -newermt “2014-10-04 00:00:00” | sed ‘s/.///g’|xargs ls -l
