In this post I am going to explore deleting a storage snapshot of an Oracle 19c RAC database created on a Dell PowerMax storage array.

This post is a companion to the video Dell PowerMax – Refresh a storage snapshot of Oracle RAC database. and a follow on from the blog post Create a storage snapshot of an Oracle 19c RAC database using ASM diskgroups with Dell PowerMax.

This blog post assumes some basic knowledge of PowerMax storage concepts. If you need a basic introduction please check out my PowerMax basics video.

These examples will use the Solutions Enabler command line method of managing the PowerMax, unlike the video which uses the Unisphere graphical interface.

In this post I am going to explore adding a new ASM diskgroup to an Oracle 19c RAC using PowerMax storage.

We will follow best practices as laid out in H17390 Deployment Best Practices Guide for Oracle with Powermax. This post is a companion to the video Create Oracle ASM diskgroups with Dell PowerMax and PowerPath.

This blog post assumes some basic knowledge of PowerMax storage concepts. If you need a basic introduction please check out my PowerMax basics video.

Powerstore Protection Policies and protecting Oracle ASM diskgroups

Posted on by • Posted in ASM, Linux, Oracle • Leave a comment

This is a quick post to demonstrate how Protection Policies can be used with Volume Groups to protect Oracle databases on Powerstore.

A Protection Policy is a powerful tool that the Powerstore storage array offers to protect application data, by automatically replicating the data to a second Powerstore which might be across the data center, or across the country.   And it can also protect the application data by generating snapshot copies of the data at a pre-determined time, or on a routine schedule.   

Such copies can then be set to auto-expire after a given amount of time.

Mounting and Opening an Oracle database created with a thin clone snapshot on Powerstore

Posted on by • Posted in ASM, Linux, Oracle, Video, VMware • Leave a comment

In my last blog post I created a thin clone of my Swingbench database on my Oracle1 server, and mounted that thin clone to my Oracle2 server.

I also renamed the cloned ASM diskgroups SWINGDATA and FRA, to CLONESWINGDATA and CLONEFRA, as I already had ASM diskgroups with those names on Oracle2 already. As a final step I renamed the individual ASM disks within each of the cloned ASM diskgroups.

In this blog post I am going to mount and open the clone on Oracle2.

Creating a Storage Snapshot of an Oracle database using Dell Powerstore

Posted on by • Posted in ASM, Linux, Oracle, Video, VMware • Tagged , , , , , • Leave a comment

Storage level snapshot are an incredibly fast and space efficient method to create usable clones of an Oracle database. In this post we’ll create a storage-level snapshot of a Oracle database using a Dell Powerstore storage array. Our database spans two ASM diskgroups, and will be mounted to a second server.

Note: There is a video of this post.
