The Check SAVSYS Authority command determines if the user has the
special authority *SAVSYS. Group profile and program adoption
authority are also considered.
The command will send CPF9898 as an escape message if the user does
not have *SAVSYS. A simple version of the command would be:
MONMSG MSGID(CPF9898) EXEC(DO)
There is an optional parameter ERRTXT that allows you to supply the
message text sent for the CPF9898 message. This is intended for
situations where you are using a Standard Error handling routine and
just want to bubble the message back. For example, assume PGMA calls
PGMB and PGMB contains CHKSAVSYS. If PGMB contains a standard error
handling routine, the error text would be sent to PGMA.
CHKSAVSYS ERRTXT('You must have *SAVSYS +
special authority to use the +
If the command completes normally, the error text is not used. If
the user is not authorized, the CPF9898 message is sent with the
error text provided.
There is no completion message if the user is authorized.
CHKSAVSYS is useful when a user makes a request to use a function
that will require saving or restoring any object on the system. You
may want to check first before using system resources for a user who
is not authorized.
Note that if the check occurs in an interactive job before a job is
submitted to batch, the command does not ensure that the user will
have authority in the batch job. Program adopt is not passed to the
batch job. You should use CHKSAVSYS in the batch job in addition.
The system does not provide a simple means of checking for *SAVSYS
special authority. The solution provided is to attempt to save the
CHKSAVDEV data area in TAATOOL to a save file in TAATOOL. Since a
normal user would not be authorized to save the object, the SAV
command fails with a CPF3770 escape message. A diagnostic message
(CPF3760) precedes the escape message, but the diagnostic is sent to
a lower level program and is not accessible. The CPF3770 message is
removed and an escape message is sent by the CHKSAVSYS CPP.
Therefore, you should see CPF3760 in the job log preceding the escape
message from CHKSAVSYS.
The CPF4104 message is also treated like CPF3770.
If the SAV command fails for some other reason that produces the
CPF3770 escape message, the CHKSAVSYS command will fail, but provide
If you suspect a problem, check the job log for the diagnostic
message that precedes the escape message sent by CHKSAVSYS.
Because of the technique used, a user who does not have *SAVSYS
authority, but who does have *ALLOBJ authority will not fail the
Command parameters *CMD
ERRTXT The error text to be used if an error occurs. The
default is *STD which produces standard error text.
The intent of allowing you to enter the text is if
you are using the CHKSAVSYS command in a program
that uses a standard error handling routine to
bubble up the message text to the caller. You can
supply some specific text relative to the function
of your program.
