The Control-D/WebAccess and 3270 terminal end users can continue working with MUF during the entire repartition process. If any records, which were copied during repartition, are updated by end users in the old location, these records are copied to the new partitions by the COPY NEW process. The COPY NEW process automatically starts at the end of the COPY step and, again, immediately at the beginning of the DELETE step.

The Control-V components that perform massive updating of the MUF cannot work in parallel with the CTDUFMPR utility, while it is performing the COPY step. If any of these components are activated when the COPY is in progress, or if CTDUFMPR is started when one of these components is working with the MUF, an error message is issued and the job is not started.

The following components cannot work in parallel with CTDUFMPR during the COPY step:

• Migration missions
• CTDDELRP
• CTVCLMIG
• CTDUPBKP
• CTDUFUPD
• CTDUFEXP
• CTDRETC
• RSTRESET
• CTDBLXRP
• CTDUFPRT
• CTDAPRV
• CTDREPUS
• CTVDELI
• CTVUPGDB
• CTVGICHK

CTDUFMPR, with the DELETE function, can work in parallel with all Control-D components, except Restore Migrated missions. The CTDUFMPR DELETE step can be submitted only after the Restore Migrated missions, which were submitted before the end of the CTDUFMPR COPY step, are completed. If CTDUFMPR, with the DELETE function, is activated before such missions are completed, the utility stops with an error message.
