Image Copy function features

The Image Copy function of IMS HP Image Copy supports the following features that are not provided by the IMS standard utilities.

Batch image copy and concurrent image copy
IMS HP Image Copy supports two types of image copy processing; batch image copy and concurrent image copy.
Parallel processing
The Image Copy function can process more than one database data sets in parallel. Processing tasks in parallel decreases elapsed processing time.
Database group processing
In database group processing, all database data groups and areas that are registered to a change accumulation (CA) group or a database data set (DBDS) group in DBRC are processed.
Stacking output image copies
Places two or more image copy data sets on the same tape or on a set of tapes (stacking) to increase the tape media efficiency.
Database pointer check (HASH Check)
The Image Copy function can check the accuracy of database pointers while it creates image copies. By enabling the Hash Check option, you need only to take image copies instead of running pointer check utilities to verify the pointers of databases. You can reduce the number of jobs for verifying the pointers of image copies taken.
Checkpoint Restart
This option provides Checkpoint Restart capabilities for the Image Copy function. You can use the Checkpoint Restart option to reprocess failed image copies without reprocessing previously successful image copies by rerunning the same JCL stream that is used in the previous run.
Logical relation search
The Image Copy function searches for all the databases that are logically related with the specified database, all the index databases that are defined for the specified database, and all the index databases that are defined for the identified logically related databases. Then the function creates image copies of all the databases, and registers all the index databases to the DBRC RECON data sets as nonstandard image copies (UIC records).
Index database search
If the index database search option is enabled, the Image Copy function searches for the primary and secondary index databases that are defined for the specified database and registers them to the DBRC RECON data sets as nonstandard image copies (UIC records).
Create multiple image copies at one time
The Image Copy function can create up to four image copy data sets for each database data set or area data set in a single run.
Switch batch image copy processing to concurrent image copy processing
If the FALLBACK option is enabled, the Image Copy function switches batch image copy processing to concurrent image copy processing when exclusive authorization of the input database is not granted.
Virtual image copy process
The virtual image copy process does not create physical image copies but registers identifiable information (UIC records) for the primary and secondary index databases to DBRC. The use of the virtual image copy process is beneficial when you want to run HASH check for an index database data set without creating image copies.
IMS command interface through IMS Tools Online System Interface
Using the IMS Tools Online System Interface ensures that the database being image copied is available and in the appropriate state. Time is saved because you need not manually bring the database down prior to image copy and up again after the image copy is complete.
Collect sensor data with Integrated DB Sensor
You can schedule Integrated DB Sensor to collect sensor data in the Image Copy function.
Integration with other IMS tools
The Image Copy function of IMS HP Image Copy can be invoked in the jobs of other IMS Tools products to create image copies within the jobs.
