While working on a client’s GoldenGate 26ai environment, I ran into a NFS-related replication issue that could have been serious, had it happened in production. Here is what happened and how the issue was fixed. The client’s GoldenGate extract was running on a dedicated server, capturing changes from an Oracle 19c source database. Trail files were written on an NFS.…
To reduce load on the Primary DB in a Data Guard configuration you may decide to do your rman backups from the Standby site. A very common approach today is to use NFS as the backup location, especially when using platforms like Exadata Cloud at Customer. I recently had a case where both the Primary and the Standby site had…
First of all, why would you use autofs over nfs mount in the fstab ? Shares are accessed automatically and transparently when a user tries to access files or directories under the designated mount point of the remote filesystem to be mounted. Shorter booting time because mounting isn’t done at boot time. Less permanently active mount points. No booting issue…

If I had to rank my favorite Oracle-related tools and software, Dbvisit Standby would likely be at the top of the list. You are reading this post, so you probably know that Dbvisit Standby is a Disaster/Recovery solution for Oracle Database Standard Edition (aka Data Guard for poor people 😛 ). The reasons why I like this product are mostly…
In my previous blog post, I talked about SQL Server on Linux and high availability. During my test, I used a NFS server to share disk resources between my cluster nodes as described in the Microsoft documentation. A couple of days ago, I decided to add a fourth node (LINUX04) to my cluster infrastructure and I expected to do this…
A couple of months ago, I did my first installation of SQL Server on Linux. I wrote about it in this blog post. So now it’s time to start the new year by talking about high availability on Linux with SQL Server vNext. Running standalone instances will be suitable for scenarios but I guess introducing high-availability with critical environments still…
