Q. Can I control the order in which Genesis migrates data?
A. Yes. There are a number of parameters governing migration order, for example, by Storage Group, By Age of Data, etc. In addition you can hold or exclude data from the migration process (so you can hold or exclude an entire Application for example).
|
Q. Why would I want to control the order of migration?
A. The data that is being converted is generally still 'active', so the conversion strategy needs to avoid contention with Production activities. |
Q. Can I control how much conversion work Genesis does each day to fit around known production workloads?
A. Yes. Genesis can be tuned via parameters held in DB2 which control exactly how much conversion work is done, when, to fit in around your exiting workloads. ICS can work with you to find windows within your daily, weekly and monthly schedules. |
Q. Once the data is selected, how does Genesis optimize migration?
A. Genesis sorts migration requests into an order where each platter is only visited once and avoids platter flips. Without this, experience shows that media mount/flip time can significantly reduce throughput (Excessive flipping is also a common cause of media failure). |
Q. Do I have to set-up the workload for Genesis every day?
A. No. Genesis includes a processing calendar which allows you to set up the entire conversion in advance. |
Q. Do I have to monitor what Genesis is doing every day?
A. No. Genesis will alert you by email if the scheduled migrations fail. Detailed logs supply information about the specific issues. |
Q. Some of our OAM data has been around a long time, what if there are data integrity issues with it?
A. Genesis can be set up to fail anytime an error is found, or continue up to a failure limit - allowing it to continue processing if it hits some bad data. Genesis outputs detailed logs when it hits a problem, allowing for follow up. Bad data can then be excluded from the conversion. Genesis allows for individual files to be excluded, ranges of files, right up to entire collections or entire applications.

Q. If Genesis hits a problem, can it be restarted?
A. Yes. Genesis has full checkpoint/restart capability. |
