TD_INIT

A second stage PLT program being executed during system initialization can issue a request for a resource that isn't yet available, because the component that services the request has not yet been initialized. If the program issues a transient data request that cannot yet be serviced, it is suspended on a resource type of TD_INIT with a resource name of DCT.

You are unlikely to see any evidence for this type of wait, unless you have trace running during initialization with DS level-1 tracing selected. An error at this stage would be likely to cause CICS to stall (see "CICS has stalled during initialization" in your CICS Problem Determination Guide), or to terminate abnormally.
