The client has also configured a small Swap mountpoint, when looking at all memory available on the server. Oracle documentation says this:
The VM has 116GB memory, and 32GB reserved for HugePages. The actual swap mountpoint is 4GB big and, based on the Oracle Server Configuration Checklist for 19c, the swap mountpoint should be in this case 16GB.
I’m using Oracle Linux 9, xfs filesystems. I’ll increase the swap mountpoint online, with the databases running.
(more…)The client uses VMWare as virtualization platform for the Oracle Database VMs (yes, he is aware of the License implications).
The VM is running out of space in two partitions. The VMWare Admin extended the disks on their platform. Now I need to make this extension visible in Oracle Linux. This things we do once every 10 years, when versions, filesystems and tools already changed.
For this post in 2025, I’m using Oracle Linux 9, xfs filesystems. All operation are online, with databases running.
I divide this post in two parts:
oracle@vmware-vm01 MIG01C $ cat /etc/system-release
Oracle Linux Server release 9.6
The partition tree is below, and I need to increase the /u01 from 50G to 100G. The disk is /dev/sda
