Event Messages (ZDLL)
DLL event messages are generated by the ZDLL subsystem on H-series systems
during the preloading of public DLLs while the processor starts. The subsystem ID
displayed by these messages includes ZDLL as the subsystem name.
A set of public DLLs includes the DLLs and these files:
If necessary, the Distributed Systems Management/Software Configuration Manager
(DSM/SCM) runs a system-generation program that:
1. Creates a new system load subvolume (SYSnn), which includes ZIMPIMP.
2. Runs the PLINSTL utility, which adjusts symbol bindings in the DLLs and
generates ZREG.
ZREG and the DLLs go on the public DLL subvolume, ZDLLrrr (where rrr is
generated by DSM/SCM).
3. Creates the ZREGPTR file in SYSnn.
When you perform a system load or reload a processor, the operating system preloads
the public DLLs by reading ZREGPTR, ZREG, and the designated DLLs. The events in
this section are generated during the preload operation.
File Description
ZIMPIMP Describes entry points in the implicit DLLs
ZREG Describes the DLLs and ZIMPIMP
ZREGPTR Designates the ZDLLrrr subvolume

Event Number and Symbolic Name Description
100: ZDLL-EVT-OPEN-ERR
A file system error occurred while opening the
specified ZREG or ZREGPTR file.
101: ZDLL-EVT-NEEDED-NOT-LOADED
A required public DLL, either the run-time
loader (ZRLDDLL) or the HP NonStop Series
TNS Emulator (ZTNSDLL), failed to preload.
102: ZDLL-EVT-DLL-FAIL
The specified public DLL in the ZREG file failed
to preload; process creation error and detail are
specified.
103: ZDLL-EVT-DLL-SUCCESS
The specified public DLL in the ZREG file was
preloadable. Either it was preloaded, or it was
discarded because of insufficient space in the
public DLL table.
104: ZDLL-EVT-NO-IMP-IMP
The required implicit_import statement was not
found in the ZREG file.
