Use the FASTLOAD statement with REG_COPY to improve performance when DTLURDMO is the only operation updating the CCT file.
When you include the FASTLOAD statement, the utility writes registration to the target CCT file at a consistent rate, regardless of the number of registrations. Without the FASTLOAD statement, utility processing runs slower when registrations are written to the CCT file, because the utility performs validations and prevents duplicate registrations for the same name or database resource. Informatica recommends using FASTLOAD if the current execution of the DTLURDMO utility is the only process updating registrations in the CCT file.
Use the following syntax:
FASTLOAD;
If you use this statement, make sure that DTLURDMO is the only process updating the CCT file. If another process tries to update the CCT file concurrently with DTLURDMO, the FASTLOAD parameter can cause errors, or the utility might fail to detect duplicate registrations capturing data from the same database resource.
