I have personally helped large customers implement Fast Path DEDB restructures with near zero IMS application outage. This same capability is also available for IMS Full-function and HALDB databases. Please contact me if you have any questions.
IMS users that BMC works with on a regular basis do not want to take IMS outages for any reason. A common scheduled outage window task involves implementing database changes. Change complexity, size of databases, and number of databases needing change dictates outage duration. This outage can be many hours in duration. DBA’s are constantly being asked to limit the number of outages a year and to also limit the duration.
BMC can now address this painful and costly task via software innovation to restructure Full-function, HALDB, and DEDB databases while those databases are available online to IMS users. BMC Restructure for IMS contains this industry unique technology to reduce these scheduled IMS application outages for IMS database restructures from hours to minutes. What does this mean to your business? Additional revenue? Additional competitive advantage? Reduced costs?
Database restructuring support includes:
Full-function and HALDB:
• Convert a database to a different database type
• Make tuning changes
• Increase or decrease segment length (such as changing from fixed length to variable length segments)
• Add and delete data set groups
• Add and delete indexes
• Add new segments while maintaining existing segment parentage
• Restructure segment data
• Add new search fields
• Add, change, and delete compression exits
Fast Path DEDB databases:
• add and remove areas
• resize areas
• perform randomizer changes
• add segments at the end of a hierarchical path
• add a sequential dependent segment (SDEP)
• add, change, or remove a compression exit
• modify lengths of variable-length segments (decrease the minimum length or increase the maximum length)
• modify segment content
