XID_HOLDER - Returns TRUE or FALSE in a symbols depending on whether or not a
X user holds a given identifier.
X
XThe following programs (images) are part of ID_HOLDER:
X
X ID_HOLDER.FOR source to ID_HOLDER
X UAIDEF.MAR $GETUAI definitions
X CHECK_ID.FOR source to check if user holds an identifier
X ID_HOLDER.HLP ID_HOLDER help file
X ID_HOLDER.DOC this file
X ID_HOLDER.CLD the ID_HOLDER command definition
X
XTo build ID_HOLDER:
X
X $ for ID_HOLDER
X $ for CHECK_ID
X $ macro UAIDEF
X $ link ID_HOLDER,CHECK_ID,UAIDEF
X $ set command ID_HOLDER
X
XThe following steps are used to install ID_HOLDER in the SYS$COMMON:[SYSEXE]
Xdirectory (to make it accessible from all cluster nodes.)
XID_HOLDER must be installed with SYSPRV privilege to provide information on
Xother users.
X
X $backup/log id_holder.exe;0 sys$common:[sysexe]id_holder.exe;0
X $set prot=(w:e) sys$common:[sysexe]id_holder.exe
X $install
X add/open/head/share/priv=sysprv sys$common:[sysexe]id_holder
X exit
X
XThe image must be INSTALLed each time the system boots, so it should be
Xplaced in the system startup file for each cluster node. Also, the command
Xmust be added to the DCL tables (or used on a process basis).
X
X $ set def sys$library
X $ set command id_holder /tables=dcltables/output=dcltables
X
XNote: If the image ID_HOLDER is put anywhere OTHER than SYS$SYSTEM, the
Xfile ID_HOLDER.CLD will have to be modified to reflect the location of the
Ximage. (DEFINE IMAGE where$it$lives:ID_HOLDER)

X1 ID_HOLDER
XID_HOLDER is a utility available on the VAX/VMS systems that allows
Xusers to determine if a given user holds a given identifier. If the
Xuser holds the identifier, a value of "TRUE" is returned in the
Xspecified symbol. If the user does not hold the identifier, a value of
X"FALSE" is returned in the specified symbol.
X
XFormat:
X
X ID_HOLDER username [qualifiers]
X2 Parameters
Xusername
X
XThe username that you are inquiring about.
X
X2 Command_Qualifiers
X
X/IDENTIFIER
X /IDENTIFIER=identifier
X
XSpecifies the identifier that you wish to know if the user holds.
XIf the user does not hold the identifier, or if the identifier
Xdoesn't exist, a value of "FALSE" is returned in the symbol.
X
X/SYMBOL
X /SYMBOL=symbol
XSpecifies the symbols in which to return TRUE or FALSE, depending on
Xwhether or not the indentifier exists.
X
X2 Examples
X
X $ ID_HOLDER/IDENTIFIER=IBM_SYSTEMS/SYMBOL=USER_IDENT JOEUSER
X $ SH SYM USER_IDENT
X X = "TRUE"
X
X
X In this example, userid JOEUSER holds the identifier IBM_SYSTEMS.
