“Come with me if you want to live” – famous words from the Terminator series.
It’s also the very reason IT companies are adopting the ‘Virtualize First’ policy to reap all of the benefits of virtualization and move away from the soon to be legacy bare metal architecture world and ‘save a bunch of money’ , just as the Gecko said.
As part of the Virtualization journey, one of the tools VMware Professional Services (PSO), Partners and Customers use to migrate applications from physical x86 servers (Windows & Linux) to VMware Virtual Machine (VM) is using the VMware Convertor tool, the process known as P2V (Physical to Virtual). It transforms the Windows- and Linux-based physical machines and third-party image formats to VMware virtual machines.
One of the most common question I get talking the VMware field, Partners & Customers as part of my role is ‘Can I use VMware Convertor to migrate Oracle databases from physical x86 running Linux / Oracle OVM running Linux to VMware vSphere platform ?’ , the answer, famous 2 words , ‘it depends !!’ .
Let me explain why I said that.
Oracle databases, being the sophisticated ‘beasts of burden’, there are many key factors to be kept in mind when we embark on an Oracle database re-platforming exercise, either between same / different system architectures, bare metal to bare metal / physical to virtual architecture, some of them include:
- source and destination system architecture
- are we moving between like architectures (x86 to x86)
- are we moving between from a big endian system to a little endian system (Solaris / AIX / HP-UX to x86)
- size and operating nature of the database (terabytes / production, pre-prod, dev, test etc)
- database storage (File system / Oracle ASM)
More information on Handiness can be found in the link below
So, if your use case is moving Oracle databases from a big endian system to a little endian system (Solaris / AIX / HP-UX to x86), Stop Right here, you cannot use the VMware Convertor tool to migrate databases between RISC Unix and Linux x86. You need an Oracle Plan and Design exercise to migrate Oracle databases between these 2 systems.
Keep reading if you are replatforming Oracle database between x86 platforms i.e. Physical server / Virtual machine (VMware vSphere / Oracle OVM) to VMware Virtual Machine (VMware).
