Oracle Database Data Protection

I’ve just published two new TR’s covering Oracle Databases on ONTAP: Database Data Protection: Backup, Recovery, Replication, and DR Oracle on MetroCluster: Integrated Data Protection, Disaster Recovery, and High Availability This is all-new material, it’s an expansive topic, but this is the first publishing and as a result I’m sure I’ve overlooked something.

Oracle RAC and misscount

Anybody out there modifying the Oracle RAC parameter called misscount? I wrote the Oracle on ONTAP best practice guide, also known as TR-3633. My recommendation in TR-3633 about changing the value of misscount is getting controversial again.

I spent some time kicking the tires last year, and I immediately saw the potential in using it for automated DR. It’s just x86 code, and it […]

Databases, QoS, and Performance Management

Friends don’t let friends use FlexShare There was a primitive QoS capability on the older ONTAP 7 systems called FlexShare. It worked okay, but it was never designed as […]

Migrating a whole %*$# array

One of the nice things about my role at NetApp is a lot of freedom to pursue projects I think will help advance our presence in the enterprise application and database space. About 25% of my time is linked to specific requests from management, but the rest of my time is discretionary. When I was […]

They explain the migration options in terms of benefits and drawbacks. The options include LVM-based migration,  ASM rebalancing, log shipping to standby databases, replatforming, etc. The point is for the reader […]
