Freeware FILES_INFO on OpenVMS 8.4 I64 Integrity Servers

How to use DECset PCA w — Fri, 18 Nov 2016 11:23:21 GMT

Hi there,

I seen on an old post (2008) that a OpenVMS user had the same issue as I'm currently having. I use the FILES_INFO freeware utility on a regular basis and have found it really useful in scripts to check updates to files are happening as expected. We're moving from ES45 running OpenVMS 8.3 to I64 Integerity servers running OpenVMS 8.4.

Hoping someone can give me some info on:

Has anyone used an updated FILES_INFO utility that runs on the I64 Integrity servers with OpenVMS 8.4?

Does it work as expected?

Is there a ported version out there that is Freeware thats been ported or is porting it something I'd need to undertake myself?

I presume this would mean either getting a C Compiler license or paying someone to procude the exe?

All information/guidance appreciated

What, exactly, are you checking?

Not I. I took a quick look at it, but I was frightened off by stuff
like:

%ILINK-E-INVLDHDR, invalid ELF header; field 'ehdr$w_e_type' has invalid value %XFE00

It's also too old to deal with ODS5 extended names. With my
(extremely) weak macro32 knowledge, I'd be looking for another way to do
whatever it is you want to do.

Yeah, but I'd guess that getting the C code compiled would be the
least of your problems.

Usually the linker prints out more information than that. The complete linker message would be useful. It shows the module. Obviously the linker got an input file, expected an ELF header and didn't find one. Looking at the input file, with the analyze or dump utility will very likely help to understand and resolve the problem.

Hi,

the link to the old post: https://community.hpe.com/t5/System-Management/Freeware-FILES-INFO/m-p/5108038#M37507

I have a database files and logs that I monitor for reads and writes to ensure that their being regularly updated. The files are likely to be open when I'm checking.

Thanks

It did better (no LINK errors) on Alpha.

Knowing nothing, I assume that the undefined things might be in some
other .STB on IA64, but "help /mess SHRINOFF" was discouraging. Someone
who knows something about VMS kernel code and Macro32 would have a
better chance than I of making this work.

Actual commands and actual output really helps :-)

No suprise, as there are "#ifdef __alpha" in the C source. I would try to replace them with "#ifdef __ia64".

On I64 .STBs are no linker input files.

I agree, the Macro32 code needs to be looked at whether it is OK for I64. To avoid the linker error, get rid of the EXEC$NONPAGED_DATA PSECT in the file_macro.mar and try a JSB to the real routine. The PSECT (and what the compiler generates) causes the linker to create an official function descriptor for something which is defined in the base (shareable) image. But, again, that may not be enough to get this working.

I'd try "#ifndef __vax" (or plain "vax", for stone-age
compatibility), which seems to work. (Wouldn't want to do this again
for x86. I must have glanced at the MMS macro, __ALPHA__, and figured
that all would be well. Duh.)

Discarding the useless "typedef" keyword quiets that one.

That's well beyond my (negligible) Macro/VMS understanding. (I could
probably handle the (C) NAM -> NAML conversion, though.)

At the moment I don't have access to an I64 system (that I can crash in case something goes wrong). I have an Alpha emulator running and can do some tests on it. I'm not sure whether (all of) the macro32 code is needed on Alpha or I64. From what I remember, there are standard calling interfaces for most of these internal routines, including CVT_EPID_TO_IPID. I'll try this on Alpha. If this works out as expected, it should work on I64 as well.

Re: Freeware FILES_INFO on OpenVMS 8.4 I64 Integrity Servers

H.Becker — Sat, 19 Nov 2016 21:43:10 GMT

Using exe_std$cvt_ipid_to_epid() seems to work on Alpha. Calling it from C can replace the jacket routine in files_macro.mar. I didn't change anything else in the Macro32 sources.

I created a new files_convert_pid.c:

#include <ssdef.h>
extern int exe_std$cvt_ipid_to_epid();
int convert_pid (unsigned int ipid, unsigned int * epid) {
    *epid = exe_std$cvt_ipid_to_epid (ipid);
    return SS$_NORMAL;
}

removed the corresponding code from files_macro.mar:

$ diff/slp files_macro.mar-orig files_macro.mar/out=sys$output
- 67, 69
- 152, 176
/
$

added files_convert_pid to the mms file:

$ diff/slp descrip.mms-orig descrip.mms/out=sys$output
- 55, 57
FILES_INFO_OBJS = FILES_INFO,FILES_MACRO,FILES_CLD,LOCK_NONPAGED_CODE, -
files_convert_pid

FILES_INFO$(OBJ) : FILES_INFO.C
files_convert_pid$(OBJ) : files_convert_pid.c
/
$

OK, this is more or less a quick and dirty change to get over the I64 linker error message and to produce an executable. Again, as I understand this code, for I64 you need to make sure the "#ifdef __alpha" C source code is compiled.

If necessary, I can drop a zip file with what I have for Alpha.

It works for me. I stuck the code into files_info.c, and added some
VAX conditionality to files_macro.mar. And replaced descrip.mms. I
haven't tried it with VAX C, but, around here:

As usual, showing exactly what you did, and exactly what happened
when you did it, would be more helpful than vague descriptions or
interpretations. "a server problem" tells me nothing useful. I see no
"files_info-30" or ".zup" in my Web server log file (which is probably a
good thing), and the only relevant 404 errors which I do see stopped
after I adjusted the file names after the last one at
"[22/Nov/2016:06:37:39 -0600]". I do see multiple successful downloads
since then. Give me something from which I can extract some useful
info, and I'll look harder.

FWIW, I downloaded the files after they were "fixed" and have had no problems unzipping the files and using them.

The problem is not with the host of the files.

Apologies, the problem was with me. My firewall was blocking it but with no indication. Switched it off and downloaded no problem. Again, apologies for the confusion.

In the past I had modified the source to extend the fmt array from 7 to 10:

char fmt [] = {"!XL !12AS !10UL !10UL !AS!AS!AS!AS!AS!AS!AS!AS!AS"};

and I think changed the header

printf ("\n PID USERNAME READS WRITES ACCESS CHARACTERISTICS");
printf ("\n-------- ------------ ----------- ----------- ----------------------");

this allowed me to cheap track of bigger files.

Thanks for the help on this one, I'm looking forward to trying it out on our new servers.

Re: Freeware FILES_INFO on OpenVMS 8.4 I64 Integrity Servers

Steven Schweda — Thu, 24 Nov 2016 01:35:42 GMT

> char fmt [] = [...]

Hmmm. Under a heading like " --------", " !7UL" does seem pretty
silly. I've posted a modified files_info.c which keeps the same total
width, but wastes less white space (" !7UL" -> " !9UL").

http://antinode.info/ftp/files_info/files_info-030/files_info.c

As I discovered when I tried to change that format string (fmt[]),
there's a touchy calculation of how much of that format string to use:
faoFmt.dsc$w_length = 28 + ((j-5)*3);

That "28" is the length out to the end of the first "!AS", which is
liable to change if that format string is changed. I'm normally all for
run-time efficiency, but I changed that (brittle) compile-time "28" to a
run-time calculation based on where the "!AS[...]" stuff starts, so if
you want more than nine digits, you should now be able to fiddle with
the format without needing to worry about also fiddling with that
formula.

I resisted the temptation to add actual status checking to the
sys$fao[l]() instances.

> [...] this allowed me to cheap [keep?] track of bigger files.

I'd say "busier", not "bigger".
