Re: IFS_OBJECT_STATISTICS equivalent over mounted drive?

Chicken lips. I have been trying all day to get this to work. I am sure a
better way exists but...
I have a CLLE that I have tested. working as I want.
I created a stored procedure that I have tested and it works fine.
Now trying to get a UDF created can not get it to work. The value it
returns is <NULL>.
I have tried several ways in both the procedure and function.

This is my CLLE works:
docsys/FldrExist.clle
PGM PARM(&PATHNAME &RESULT)
DCL VAR(&PATHNAME) TYPE(*CHAR) LEN(132)
DCL VAR(&RESULT) TYPE(*CHAR) LEN(20)
DCL VAR(&dtaaraval) TYPE(*CHAR) LEN(2)
/*
*/
qmgtools/CHKIFS IFSDIR(&PATHNAME) CRTDTAARA(Y) DTAARA(CHKIFS) +
DTAARALIB(QTEMP)
RTVDTAARA DTAARA(QTEMP/CHKIFS (1 2)) RTNVAR(&DTAARAVAL)
IF COND(&DTAARAVAL = '00') THEN(DO)
CHGVAR &RESULT 'Obj_Not_Found'
enddo
IF COND(&DTAARAVAL = '10') THEN(DO)
CHGVAR &RESULT 'Obj_Found'
enddo
ENDPGM: ENDPGM

This is my stored procedure create:
CREATE OR *REPLACE* PROCEDURE docsys.folderExist (
IN PathName *CHAR*(*132*),
INOUT results *CHAR*(*20*)
)
LANGUAGE RPGLE
NO SQL
DETERMINISTIC
EXTERNAL NAME docsys.fldrexist
PARAMETER STYLE GENERAL WITH NULLS

This is my test of stored procedure:
call docsys.folderexist ('/home/kcrawfrd', ' ')
The result is 'Obj_Found'

This is my function:
CREATE OR *REPLACE* FUNCTION docsys.Folder_Exist (
PathName *CHAR*(*132*)
)
RETURNS *CHAR*(*20*)
LANGUAGE sql
DETERMINISTIC
BEGIN
DECLARE Results *CHAR*(*20*);
CALL docsys.FolderExist(
PathName,
Results
);
RETURN Results;
END

This is my test of function:
SELECT '/home/kcrawfrd',
docsys.Folder_exist('/home/kcrawfrd')
FROM sysibm.sysdummy1
The result in second column is <NULL>

TIA

Wrap a UDF which gets the results of that command?
QMGTOOLS is not the only version of CHKIFS in the ether. Perhaps someone
has a UDF wrapped around that version?

Jack, the SQL works over a native IFS drive but not a mounted drive.
Rob, I will look at the QMGTOOLS/CHKIFS a bit more. my first glance is

yes

it works. It is creating a data area and putting 00 in it if the

directory

did not exist and a 01 if it did. Trying to figure out how to use this.
My hope was using my ctrlFile come up with a list of all directories that
do not exist. With the CHKIFS using a data area not sure how to use that
with my SQL statement. I guess I will need to write a program that will
read the ctrlFile run the command CHKIFS look at the data area then

decide

if it was found or not populating table. That is a bit more work than I
wanted to do. Lazy at heart.

I have a mounted directory. This works
QMGTOOLS/CHKIFS IFSDIR('/GDWEB/tmp/sshd.pid')
There's no help on that command. I did a DSPJOBLOG to figure out how

it

worked.

In case you're wondering:
Allow RTVCLSRC (CL module) . . . . . . . . . . : *NO

I am trying to verify that folder names in a control file do exist on

the

IFS/mounted drive.
I can use this SQL, and it appears to work over an IFS drive.
SELECT ftpdir, c.*
FROM myLibrary.myCtrlFile c
WHERE *UPPER*(ftpdir) NOT IN
(SELECT *UPPER*(*SUBSTR*(PATH_NAME, *16*, *15*))
FROM TABLE (QSYS2.IFS_OBJECT_STATISTICS('/home/myFolder/',

'YES'

, '*ALLDIR'))
)
But my directory is a mounted drive. IFS_OBJECT_STATISTICS will not

work

over mounted drives.
Do I have any other options?
