What are the responsibilities and job description for the Oracle Server Migration (LDOM) Specialist position at New Millennium Consulting?
Job Details
One of our clients is urgently looking for an Oracle Server Migration (LDOM) Specialist.
Scope:
Oracle Server Migration - Support Oracle LDOM configuration and Solaris migrations
There are two Oracle Sparc servers:
T4-1 server running Solaris 10 with 2 x Solaris 8 zones.
- This system is in production use for generating reports.
- The only COTS application on the system is Mathworks Matlab, there are no DBs on the system.
- The users access the zones only, and both zones are identical, users don’t use the Solaris 10 primary OS…only the S8 zones.
- Client can’t or don’t want to upgrade the Solaris 8 OS on the 2 zones but the h/w is aging...thus the replacement server.
S7-2 server running Solaris 11.
- This system is new and not yet in use.
- This system was purchased as a replacement for the T4-1 system and came with S11 pre-installed.
- The S7-2 platform does not support Solaris 10 natively…only inside an LDOM.
- Users will not use the S11 or S10 OS’ directly, only the S8 zones once they are migrated to this new hardware.
The process to migrate the S10 system (including S8 zones) as described to us by Oracle is to :
- Create a flash archive (FLAR) or backup of the entire S10 system and store it on a common accessible network share…
- Create an LDOM on the S11 system and allocate or assign 90% of the physical system resources (CPU & mem) to the LDOM.
- Install S10 from the backup (or FLAR) inside the LDOM on the S11 system. This install will contain both the S10 system and S8 zones/containers.
Project's Expectations:
We need help with steps 2 and 3 above. We plan to clone the S11 boot disk before creating the LDOM so we can easily revert back and try again if unsuccessful. We have extra HDD’s available and may need help with this part as well, unsure.
NOTE: The S11 system is configured and accessible over the network. We will perform the S10 backup in advance of your involvement. The S11 system is not in production use so downtime is not an issue.
Client's Note:
One of the systems we have under the support is an Oracle T4-1 server running Solaris 10 with Qty 2 Solaris 8 branded zones on it.
We would like to migrate that entire environment to a new Oracle S7-2 server.
The S7-2 server has Solaris 11 installed and doesn’t support Solaris 10 directly so the recommendation is to create a Logical Domain under S11 and install / host the S10 (and S8 zones) into the LDOM.
The admin supporting these servers lacks the experience to create the LDOM and doesn’t have the bandwidth to research it properly at this time.
Need expertise with LDOMs
