I tried to apply a patch to my 18.3.0 GI/ASM two node cluster on RHEL 7.5. The first node worked fine, but the second node got always an error…

The DOAG 2018 is over, for me the most important topics were in the field of licensing. The insecurity among the users is great, let’s take virtualization on the ODA, for example: The starting point: The customer uses Oracle Enterprise Edition, has 2 CPU licenses, uses Dataguard as disaster protection on 2 ODA X7-2M systems and wants to virtualize, he also has 2 application servers that are also to be virtualized. Sure, if I use…
Unbelievable! After more than 10 years working in the Oracle Database environment, this year was my first participation at the DOAG Conference + Exhibition.
Introduction X3-2 and X4-2 ODAs are still very capable pieces of hardware in 2018. With 256GB of RAM and at least 16 cores per node, and with 18TB RAW disk capacity as a standard these appliances are far from obsolete even you probably don’t have any more support on the hardware from Oracle. If you own several ODAs of this kind, hardware support may not really be a problem. If something fails, you can use…
During this second day at Oracle Open World 2018 (24.10.2018) I attended to Mark Hurd’s keynote name “Accelerating Growth in the Cloud.

Introduction : Oracle ASM Filter Driver (Oracle ASMFD) simplifies the configuration and management of disk devices by eliminating the need to rebind disk devices used with Oracle ASM each time the system is restarted. Oracle ASM Filter Driver (Oracle ASMFD) is a kernel module that resides in the I/O path of the Oracle ASM disks. Oracle ASM uses the filter driver to validate write I/O requests to Oracle ASM disks. In this blog I will…
By Franck Pachot . COMMIT is the SQL statement that ends a transaction, with two goals: persistence (changes are durable) and sharing (changes are visible to others). That’s a weird title and introduction for the 499th blog post I write on the dbi-services blog. 499 posts in nearly 5 years- roughly two blog posts per week. This activity was mainly motivated by the will to persist and share what I learn every day.
It should never happen but sometimes it happens. You just lost your datafiles as well as your fast recovery area (probably because most of the time these areas are on the same disks despite the recommendations). Normal restore operations with RMAN are quite easy and secure as far as you have backupsets for database, archivelogs, and spfile/controlfile: Step 1 – restore the spfile and start the instance Step 2 – restore the controlfile and mount…
