  • Oracle Linux (up until 9.3 I think?) is a direct clone of RHEL. After 9.3 (or maybe it’s 9.2) it’s a best attempt clone of RHEL (similar to Alma Linux or Rocky Linux). If you want to learn RHEL then it’s a fairly decent equivalent with a couple of their own quirks thrown in (ULN, ksplice and the UEK).

    Also, I don’t bother with certs or care if people have them. I have yet to find someone who knows a product better having got the cert than someone who’s used the product without a cert.

















  • I had to upgrade some OL6 VMs to OL7 VMs running Oracle DBs and Apps (on OVMM no less). There was no appetite for buying additional storage, or restoring the environments with RMAN. Luckily, everything had been installed under /u01 which was on its own virtual disk.

    So I built a new VM as OL7 (same hostname, etc.), installed the pre-req RPMs for Oracle DB, disconnected the virtual disk from the OL6 and attached it to the new OL7, synced users and home dirs - and it only bloody worked.
