Error description
Currently we require IMS to be shutdown before we can clone an IMS subsystem. This enhancement will allow subsystem cloning to occur while IMS is active. The capability is added to suspend access to the source volumes prior to , and during, the COPY phase. This allows for a copy of the source IMS to be made that is in a dependent-write consistent state. If IMS was active during the COPY step, IMSUPDATE will now update the OLDS and RDS in order to allow for an emergency restart of the target IMS which will create a transactionally consistent state. This requires new keywords to identify the RDS/RDS2 data sets - IMSRDS-DSN and IMSRDS2-DSN. IMS Cloning Tool Userexits must be installed into the IMS.SDFSRESL or in the STEPLIB for the IMS Control region and DL/I batch regions in order for IMS Cloning Tool to be able to suspend an active IMS subsystem.
Local fix

Problem conclusion
Temporary fix
Comments
1. Add online IMS Subsystem Cloning support 2. Add new command to suspend or resume an IMS system(s) as part of cloning an online IMS Subsystem Cloning: IMSSETLOG (SUSPEND | RESUME) 3. Add new keywords to IMSUPDATE command for online IMS Subsystem Cloning: IMSRDS-DSN(data set name) IMSRDS2-DSN(data set name)
