SQDutil can perform a number of functions that can have immediate operational implications. For that reason Connect CDC SQData provides the means to control its actions procedurally and on z/OS platforms through the z/OS System Authorization Facility (SAF).
- z/OS LogStream Functions
- z/OS Security Options
z/OS LogStream function
Each Action supported by SQDutil has the potential to negatively affect Connect CDC SQData operating in a production environment. While standard operating procedures should prevent most problems, special care must be taken with two Actions, Move and Clean:
- move - is destructive, source records are consumed.
- clean - SQDUTIL has no way to know what is in the LogStream specified. It can clean any LogStream the user has write access to, including possibly VSAM forward recovery logs or even a system zlog. Double check the content of the LogStream and the value specified for the Storeclock using the dump action first. Be VERY cautious before using Clean against a production datastore.
