Cloning database system on vsam based dataset

A computer program product for database cloning, the computer program product comprising a non-transitory computer readable storage medium having program instructions embodied therewith, the program instructions executable by a computer to cause the computer to perform a method comprising:

• initiating, by a hardware processor of the computer, an outage-free backup of a production database of a source database system using a predetermined point-in-time copy technology which copies both data and object structure, responsive to a request to perform a clone of the source database system;
• executing, by the hardware processor, a predetermined cloning command to open a dialog panel menu receiving as input a subsystem name used to generate a set of database restore jobs;
• executing, by the hardware processor, the set of database restore jobs to clone data into a predetermined transient area;
• using, by the hardware processor, a predetermined copy management service to activate replication of the data from the source database system created using the predetermined copy technology to a target database system;
• exporting, by the hardware processor, a file catalog associated with the source database system to the target database system;
• and
• executing, by the hardware processor, a predetermined script to rename files according to specifications of the target database system and the file catalog.

A computer processing system for database cloning, comprising:

• a memory device for storing program code;
• and
• a processor device, operatively coupled to the memory device, for running the program code to:
• initiate an outage-free backup of a production database of a source database system using a predetermined point-in-time copy technology which copies both data and object structure, responsive to a request to perform a clone of the source database system;
• execute a predetermined cloning command to open a dialog panel menu receiving as input a subsystem name used to generate a set of database restore jobs;
• execute the set of database restore jobs to clone data into a predetermined transient area;
• use a predetermined copy management service to activate replication of the data from the source database system created using the predetermined copy technology to a target database system;
• export a file catalog associated with the source database system to the target database system;
• and
• execute a predetermined script to rename files according to specifications of the target database system and the file catalog.
