RDF System Management Manual for J-series and H-series RVUs (RDF 1.10)

During ZLT Takeover Processing
During Phase 1 of the ZLT Takeover processing, the shutdown audit-record is not stored in image
trails, and the RDF processes continue running.
The goal of ZLT processing is to catch up data as quickly as possible. Thus, there is no point in
stopping RDF processes if a STOP TMF record is found in the master audit trail (MAT).
SQL Shared Access DDL Operations
Normal support for SQL shared access DDL operations is provided during ZLT takeover operations:
• The updaters are guaranteed to stop at the correct locations.
• If some of the updaters terminated prematurely while a shared access operation is in the
system, only those that had not completed the task are restarted during the next takeover
operation.
