Resource type TD_INIT: waits during initialization processing

A second stage PLT program that is being run during system initialization can issue a request for a resource that is not 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, the program 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), or to terminate abnormally.
