This blog post will guide you on how we can extend the swap space for an existing LVM volume. For using this method LVM volume must have free capacity to accommodate the new swap space. If the space is not available in an existing LVM then this method is not helpful. Check the existing swap : [root@racnode1 yum.repos.d]# grep swap /etc/fstab /dev/mapper/ol_racnode1-swap none swap defaults 0 0 [root@racnode1 yum.repos.d]# ls -l /dev/mapper/ol_racnode1-swap lrwxrwxrwx 1 root root 7 Mar 15 23:00 /dev/mapper/ol_racnode1-swap -> ../dm-1 [root@racnode1 yum.repos.d]# ls -al /dev/mapper/ol_racnode1-swap lrwxrwxrwx 1 root root 7 Mar 15 23:00 /dev/mapper/ol_racnode1-swap -> ../dm-1 [root@racnode1 yum.repos.d]# Before extending the swap volume disable the swap: [root@racnode1 yum.repos.d]# swapoff -v /dev/mapper/ol_racnode1-swap swapoff /dev/mapper/ol_racnode1-swap [root@racnode1 yum.repos.d]# Now extend the LVM swap volume: [root@racnode1 yum.repos.d]# ...

This article will guide you how you can add the swap space on Oracle Linux 8.x operating system. In this method we will use the swap file for adding it to the swap memory. Currently allocated swap memory – 8 GB New swap memory to be added – 32 GB [root@racnode1 ~]# df -h Filesystem Size Used Avail Use% Mounted on devtmpfs 756G 0 756G 0% /dev tmpfs 756G 4.0K 756G 1% /dev/shm tmpfs 756G 27M 756G 1% /run tmpfs 756G 0 756G 0% /sys/fs/cgroup /dev/mapper/ol-root 100G 2.8G 98G 3% / /dev/sda2 945M 223M 658M 26% /boot /dev/sda1 488M 5.2M 483M 2% /boot/efi /dev/mapper/ol-oracle 500G 3.6G 497G 1% /oracle /dev/mapper/ol-ortrace 500G 3.6G 497G 1% /oracle/trace tmpfs 152G 0 152G 0% /run/user/0 [root@racnode1 ~]# Create swap file with 32GB size: [root@racnode1 ~]# dd if=/dev/zero of=/root/newswap bs=1M count=327...

  In this blogpost we will see how can we change the time and time zone on Oracle Enterprise Linux 8 Server Check the existing configure time and time zone  on Server: [root@OEL8-Server1 ~]# date Mon Mar 13 06:47:05 EDT 2023 [root@OEL8-Server1 ~]# timedatectl                Local time: Mon 2023-03-13 06:47:46 EDT            Universal time: Mon 2023-03-13 10:47:46 UTC                  RTC time: Mon 2023-03-13 10:47:48                 Time zone: America/New_York (EDT, -0400) System clock synchronized: no               NTP service: active           RTC in local TZ: no As you can see NTP service is active it will not allow to change time manually.   [root@OEL8-Server1 ~]# timedatectl set-time 13:48:33 Failed to set time: NTP unit is ac...

In this blogpost we will see how we can configure local repository on Oracle Enterprise Linux 8, As you know installation of rpm packages is never been very easy when individually  (without using repository), there may be many dependencies for installation of single rpm. Hence its always a good practice to use package repository either local or public for  installation of rpm package. But in this post we will see how we can configure the local repository on the server. We must have the media/DVD to configure the local repository. - Copy media to any valid directory where you want to configure the repository - Create and Edit Local repository file and use the location where the content has been copied recently - Check the newly configure repository - Now the repository is configured an ready to use. Conclusion: Local repository configuration is simple and its helpful on servers where you cannot configure internet on the server for installatio...
