Libnames.param File
The libnames.parm file defines the SPD Server LIBNAME domains for the SPD Server
environment. The libnames.parm file is a collection of LIBNAME statements. Each
LIBNAME statement defines a storage domain that SPD Server uses with clients. You
modify the libnames.parm file using the
-libnamefile
option with the spdsserv
command.
Residual Lock File
When SPD Server accesses a data resource or table within a LIBNAME domain, it
creates a lock file. The local operating environment uses the locking mechanism to
ensure that proper member-level locking is observed by all SPD Server processes that
access the named data resource. If a LIBNAME proxy process terminates unexpectedly,
the residual lock files remain in the LIBNAME domain. Residual lock files cause no
problem upon subsequent accesses because the lock belongs to the operating
environment. The lock is cleared when the process terminates and does not depend on
the presence of the file itself. However, unused residual lock files can accumulate and
create clutter in your primary domain directory.
Residual Temporary File
SPD Server creates temporary files when you create a new resource in a LIBNAME
domain. If the SPD Server LIBNAME proxy process terminates unexpectedly while
you are creating a new file, the residual temporary files remain in the LIBNAME
domain directories. These temporary files are named with a leading '$' character, which
prevent the residual temporary files from appearing in a PROC DATASETS directory
listing. You should periodically remove old or abandoned residual temporary files that
were created by unexpected proxy process terminations.
Spdsserv.parm File
The spdsserv.parm file defines the SPD Server operating parameters. The
WORKPATH= statement in this file lists the directories that SPD Server will use for
transient or working disk storage. To specify the spdsserv.parm file, use the spdsserv
command with the
-parmfile
option.
System-Specific Temporary Files
SPD Server uses pre-assigned directories (which vary by operating environment) that
are designated for temporary files. The pre-assigned directories hold files, logs, and
other temporary entities that SPD Server creates while running. SPD Server normally
cleans up these temporary files when exiting. If SPD Server terminates abnormally,
these temporary files might be left in the temporary directory. In UNIX operating
environments, the temporary files would usually appear in the directories such as
/
tmp
or
/var/tmp
. In Windows operating environments, the temporary files are
usually stored in
C:/TEMP
(or wherever the user profile is configured to store
temporary files).
