RE: Checking object create dates



fixed

Glad it's better.

My full solution to make sure my test environment matched production used API's, output written into a file and then the files compared. For all objects in the libraries I was concerned with I first determined the object type, then called an appropriate API (main RPG programs displays the objects in the library out to a file then reads the file and checks the type and calls subroutines):

*PGM QCLRPGMI (if ILE, also calls QBNLPGMI and outputted into a user space to flip though the modules).
Store source file name and library and member, and source update time for comparison for the program or each ILE module
*FILE QDBRTVFD (format FILD0200)
Store the level identifier (this API is no fun at all)
*DTAARA QWCRDTAA
Store the type, length and decimal positions if any
*DTAQ QMHQRDQD
Store the message length, key length, if sender id included, type, max entries and a couple other assorted
(Was somewhat lazy and omitted DDM data queues)

Then when the file is built with the above data from the production system I send it to the test system, run the same code over the test libraries into a different file and then compare the results. Anything that doesn't match I take an extra look at.

This gives me a good confidence my test libraries match production with the exception of objects actually being tested. Clearly I don't cover all object types and there certainly are ways that some differences could be missed, but I feel this is a good general regular accounting (I run it weekly) that tells me that objects aren't going into production without going through test first and/or that my environment does not reflect production - which are my main concerns. Of course in the file comparison mismatches are reported as well (on one system but not on the other).

Hope this helps

Jim,

In the query/400 that compares the 2 outfiles, I added a source date check, that worked.
Only 1 object remains on report.
May not be 100%, but much better than it was.

Mark,

I do use dspfd for some of my other utilities.
Time to regroup, this is no longer simple.

I remember many moons ago a CRTDUPOBJ PMR I had with IBM, questioning the create date and create user. I felt they should be the same, but that was not the case.
Maybe we need another IBM data area, one for CRTDUPOBJ, so we get the desired results.

CRTDUPOBJ is what's causing this issue.

Paul:

That is fine for a "top level" compare to identify objects that possibly might be different in some respects.

What I was trying to suggest was something like this --

For each such object with a different create date, you should then "drill down" to do some extra checks, such as comparing the source member last changed date/time stamps, and then, for *FILEs, you might want to issue DSPFD to generate the additional *OUTFILEs, to allow for a "deeper" comparison of all of the other attributes that could be changed, and that are not reflected in the create date or Record Format Level IDs.

Hope that helps,
Mark

Mark,

I use dspobjd instead of dspfd because I need to account for all object types.
I do have two outfiles and I do use query/400 for the compare.

Paul:

For *FILEs, you can issue DSPFD ... TYPE(*ATR) OUTPUT(*OUTFILE)
OUTFILE(QTEMP/QAFDPRT)

Issue the DSPFD for the first file with OUTMBR(*FIRST *REPLACE) -- then issue the DSPFD again for the second file, with OUTMBR(*FIRST *ADD) ...

Then, you can write a program to read the two records and compare them, field by field, to determine what is "different" among the various printer file attributes.

You can do similar things for PFs, LFs, DSPFs, etc. -- pretty much all kinds of files.

If you do not want to write a program to to the analysis, you can use two separate *OUTFILEs and then use Query/400 or QM/400 or an SQL query to do the "compares" ...

Hope that helps,

Rob,

Good point.
Prtf identifiers could be the same, but the prtf have different attributes.

I just did some tests.
1) CRTDUPOBJ of prtf creates a new file level identifier.
2) Restore of a prtf from a different system keeps the same file level identifier.
3) Changing the attribute of a prtf does NOT change the file level identifier.

I'm not seeing a solution.

What value would change of the format level id if you ran a CHGPRTF PAGESIZE(67)? Probably none. Is it important to catch that? Or related changes? HOLD(*YES)? Would the users care if you rolled out a new version and clobbered all of those settings?

True, there is also CHGMOD for programs.

But such changes should be tracked with some kind of change control I
would think. So source change date for programs is the best I've been
able to find. I'm sure that there is always a way that would not be picked up.
Using the API's to go through the module(s) individually might get
you closer.

For printer files, how about the Format Level Identifier (shown in a
DSPFD)?

That's a false assumption.
Lots of objects get changed outside of the source. Especially
printer files. Hey, let's run a CHGPRTF to change... A good change
management system will flag you when something was changed outside of
the change management system.
We were running into issues where we would promote a new printer file
change, miss the CHGPRTF issues, and users got upset.
Other possible issues: CHGOBJOWN, CHGAUT, etc.

Maybe
Crtdupobj carries the original source date, thus both source dates
are equal.
Problem is that my utility uses dspobjd detail(*full)
output(*outfile), source dates are not in the outfile.
If I change my utility to use detail(*service), I see the source
dates in the outfile.

So, would it be correct to say that if two objects have different
create dates, but the source dates are equal, the objects are equal.

Fix library
Creation date/time . . . . . . . . . : 08/15/11 10:41:44
Source file date/time . . . . . . . : 04/01/11 01:52:05
Std library
Creation date/time . . . . . . . . . : 08/28/11 10:49:35
Source file date/time . . . . . . . : 04/01/11 01:52:05

If you do a DSPOBJD with DETAIL(*SERVICE) it shows the Source file
date/time. Will this work for you?

Subject: Checking object create dates

I'm working on a utility to find objects that exist in a
custom/emergency fix library that would have a create date lt the
create date of the object

in the standard library, thus sign of an issue.
Utility done, working.
However, I found a scenario where we received a new object (*prtf)
for an upgrade. Because we change some print attributes on a few of
these, we place a copy of these prtf file objects in the fix library.
The upgrade is done, replacing the objects in the standard library.
Here's the issue.

The prtf object in the fix library was created with crtdupobj, prior
to the upgrade being done.
Creation date/time . . . . . . . . . : 08/15/11 10:41:44
The prtf object in the standard library has a create date for the day
of the upgrade.
Creation date/time . . . . . . . . . : 08/28/11 10:49:35

The objects are valid, but being flagged because of the create date issue.
I'm looking for some other field on the object, not finding any.

Many of our upgrade processes do this. The upgrade process does a
crtdupobj, thus the object loses its original info, (create date,
created by user)

Thank You
