The Convert Object Lock command converts the object locks to a data
base file OBJLCKP with one record per lock. This allows you to
determine who has the lock within a program (ALCOBJ does not provide
any feedback on which job has the lock). The model file in TAATOOL
is TAAOBJDP with a format name of OBJLCKR.
A typical command would be entered as:
CVTOBJLCK OBJ(xxxx) OBJTYPE(*FILE) OUTLIB(QTEMP)
The command creates a file named OBJLCKP in QTEMP with one record for
each lock that is held. You can then read the file in a CL or other
HLL program.
The API QWCLOBJL is used to convert the locks.
An option exists to determine whether an escape message will be
issued if no locks exist on the object.
Command parameters *CMD
------------------
OBJ The qualified object name who's locks should be
converted. The library defaults to *LIBL.
OBJTYPE The object type such as *FILE, *DTAARA etc.
MBR The member if a file is specified. The default is
*NONE. For a non-data base file objects, this
causes only file level locks to be converted. For a
data base file object, no member level locks will be
converted.
If a specific member is named (or *FIRST or *ALL),
both the member level and data locks will be
converted.
OUTLIB The library in which the file OBJLCKP will be
placed. The default is *LIBL. If the OBJLCKP file
does not already exist, a library must be specified.
OUTMBR The member of the OBJLCKP file to be used. If the
member does not exist, it is added. The default is
OBJLCKP.
REPLACE A *YES/*NO value for whether the member should be
cleared before writing records into it. The default
is *YES.
NOLCKMSG A *YES/*NO/*SPCID value that determines whether an
escape message will be sent if no locks exist for
the object. The default is *YES which causes the
CPF9898 escape message if no locks exist.
*NO may be specified to avoid the escape message in
which case the OBJLCKP file will exist in the
specified library, but not contain any records.
*SPCID may be specified to send TAA9897 as an escape
message if no locks exist. This allows a specific
condition to be monitored for.
