  • This is it. I used to work for a consultancy that specialised in Oracle products. Turns out if you want an ERP or HCM, running Oracle EBS with a DB backend on Oracle…running on Oracle Linux…on Oracle Linux KVM hypervisors (where CPU pinning is a recognised and allowed tactic - unlike Oracle on other hypervisors)…it turns out, might be competitively priced.

    It’s a total lock in. Also, I get the impression that it’s almost always up to what the Finance team is used to/familiar with. They decide the finance app - then everything else follows as above due to the financials…which they are in charge of.

    I know a guy who migrated workloads off PostgreSQL Enterprise back to Oracle as the performance and availability just wasn’t good enough. I don’t know enough about DBs to query that much, but he did it.







  • Linux has always had a hard line disposition about keeping Kernel-space and User-space separate. SSHD (and systemd) are User-space, but are being configured on the kernel’s boot line (in GRUB, which is also User-space).

    I don’t like to use the term rage-bait, but this post is suggesting that User-space components should not be configured by the Kernel-space (which is not happening here, it’s just the kernel boot line parameters, you could, pass the parameter to start a different init system other than systemd).











  • 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.
