I sat through his sessions.

I sat next to my husband the last couple years while he implemented virtualization.

I virtualized environments with Oracle’s products in a number of customer implementations as an expert in the area.

If I was this close to it and missed it, so possibly were others…

Kyle’s goal was this for years…


The goal here is to use one use case to help drive the epiphany of virtualization.

A Single Use Case


Why do we still patch and upgrade the old fashioned way?

After three months at Delphix…. Recognized the benefit of virtualization and addressing tedious tasks. How to describe a complex topic that simplifies?

The message was challenging….Maybe it was the sticky notes.


Patching and Upgrading….


Standard Database Environment

Now You Have To Maintain All Of It


Patching and Upgrading Databases

Each patch, (PSU) would need to be applied to a development database, requiring outage to development teams and then tested before applying to test, QA and then onto production.

This has to be performed to EACH environment, every database, each quarter.

HR

CRM

Quarterly PSU Patching isA Major Undertaking


• Downtime for valuable resources.

• DBAs working afterhours

• Each database must have it done and…- The tedious task must be performed over and over

again.- Little opportunity for advanced learning.- Each database may experience different bugs.

Spin a VIRTUAL database up a patch test, without having to remove a current development or test one.

The CLI, (Command Line Interface) is very robust for Delphix and Creating VDB is easy!

I’m a Command Line Person, Whatcha Got?

• The name of the VDB you want to create• The group in which to create the VDB• The Oracle database name• The Oracle database unique name• The Oracle database instance number• The Oracle database instance name• The source dSource or VDB from which you wish to provision• The SCN or timestamp of the point you want to provision from, (commands

can be run to get the list of snapshots or timeflow ranges.)

Choose Source Snapshot:>snapshot list database=<dbname>timeflow ”<dbname>" timeflowRanges; commit;

Create A Virtual Database:>database provision;delphix database provision > defaultsdelphix database provision defaults > set container=<Vdbname>delphix database provision defaults > commit;

What a CLI Scripted Refresh Looks Like

> database> select <VDB name>> refresh> set timeflowPointParameters.type= (one of TimeflowPointBookmark, TimeflowPointBookmarkTag, TimeflowPointLocation, TimeflowPointSemantic, TimeflowPointTimestamp as appropriate)> set timeflowPointParameters.location= (the location, timestamp, or bookmark you wish to refresh to)> set timeflowPointParameters.timeflow= (the timeflow associated with location)> commit


• Monstrous deployments, (20+) benefit from a scripted, CLI option.

• Single or several VDB deployment.

• When investigating deep level issues, using the CLI can make details easier to search through.

• When looking for “just the facts”, then a graphical UI is beneficial for high level error messages.

• Self-service has great benefits and make it simple for those without deep level skills to take advantage of virtualized environments for development and testing.

When Do I USE the CLI or Graphical UI?


Cost Vs. Benefit…• No Management Packs outside of database

feature licensing.• Heterogeneous Opportunities


Spin up a new VDB and apply patch

there- no need to commandeer

existing!

• Not only did I save on 80% or more on storage usage overall.

• I didn’t have to take away a valuable resource’s database environment to test the patch/upgrade.

• I didn’t have to apply the patch/upgrade to each environment, as they are virtualized copies of the source.

• I save significant time that commonly has to be allocated to quarterly and annual maintenance for patching and upgrading.

• I apply the patch twice- once to test, once to production. I only need to refresh my environments after I’m done.

• This works for the database AND application tier.

Patching and Upgrading with Virtualization


The quickest way to complete a task is not having to do it.

And there’s the epiphany…
