Hi All,

 

I have heard back from the customer.  The work-around does indeed work
around the problem.  It seems the bug is related only to building the short
description string for an ARGetListEntry response.  The server comes back to
the client and the client responds that it can't decode the result (ARERR
992) if and only if the any of the result's descriptions have umlauts.  

 

Meta-Update uses that string in its messaging:  Qry 1 of x: default short
description (get fields) from the record.  Simple solution for those using
the API is to override the default short description generation with a
single field known to not contain any special characters such as umlauts
(such as '1').

 

This bug seems to have been introduced in 9.1 or at least this customer did
not experience it before the upgrade to 9.1.0 - from which version I know
not - but running on HP-UX. :)  I haven't tested in on my servers (9.1.02,
8.1, .) to see when it was introduced and the fact that I run UTF-8 may
affect the test.

 

Cheers

Ben

Hi Fred,

 

Thanks for your reply.

 

I have no access at all to the client Windows machine or the Linux server -
not even WebEx.  As for the DB, I expect the BMC software is not lying when
it reports its character set.  The info below is from the values of the
server info stuff which Meta-Update makes available to you on startup.  The
./arsys reports LANG, LC_ALL with en_US.UTF-8

 

I did check on my server and was surprised that the machine, the Remedy
user, etc seems to be on utf8 and the DB on utf16 - and a different locale
as well.

 

I suppose it would be easy enough to look at ITSM's normal forms and stick
an umlaut in one of their query results fields.  Your email has spurred that
idea, so I thank you for that.  I am still waiting the results of the
enhancement (step 1) and patch (if matching the locale and charset fails) I
gave the client.  The patch will circumvent the whole problem as the query
will only return field 1 as its short description.

 

I am unclear what strings to set on the client for locale and charset to
match.  In particular relating to the "iso" prefix:  de_DE.iso-8859-15 or
de_DE.8859-15

 

Thanks again Fred.  I know I can count on you when it comes to Linux and
Oracle.  Is Axton still around?  My 8.1.02, 9.1.02 servers are running that,
though my 7.6.04 is running Windows (on XP64 I believe!) MS SQL server.  I
upgraded a copy of 8.1 to make my 9.1.02 but I think I need to build one
from scratch in both Linux and Windows.

 

Thanks again,

Ben

Look at the values of

   CLIENT_LOCALE             en_us.8859-1

   LANG                                 C

   LC_ALL                              C

 

What is the database character set you see when you run the following   

SELECT * FROM NLS_DATABASE_PARAMETERS ;   

 

We currently have a 9.1.02.003 system Red Hat Enterprise Linux Server
release 7.2 (Maipo) (Linux 3.10.0-327.36.1.el7.x86_64) 

Using   NLS_CHARACTERSET   US7ASCII

 

I have not seen your error

Fred

Hi Folks,

 

I have a customer using what I think of as a first.  An Oracle DB with
charset 

DB_CHAR_SET := (11) iso-8859-15

 

This is against ARS 9.1.00 201610281101 running on Linux
2.6.32-573.3.1.el6.x86_64 against Oracle 12.1.0.2.0 - 64bit Production.

 

I issue a Query and the response includes the default Form based list of
query fields.  There apparently is no way to request none.  You can override
the default which is the obvious work-around and will be tested shortly.
Presumably, you may say the client is using the same character set and get
around the issue being thrown by the translation dlls.

 

In this case the form's query fields includes those with umlauts.  When such
a record (containing an umlaut in a form specified query field) is queried,
the ARERR 91 occurs.  When said query returns records with no umlauts in the
generated "short description", there is no error.

 

The client (Meta-Update) is running under Windows and is compiled with 9.1
libraries.  An 8.1 library version also suffered the same problem.  The
Linux version has not yet been tested.  

 

I would tend to think it is a client api responsibility - given the plethora
of modified character translate open source dlls - but the fact that both
the 8.1.2 and 9.1 compiles behave the same way (with changes in these
supplied dlls) - makes me want to think of the server.

 

I guess after spending some hours, I am quite curious.  I believe I have an
enhancement that may work (to define the character set as above in the
ARControl block) and one that most likely will work (to request an override
to the form's configured fields).

 

So, 

1.      Anyone ever experienced this?  We have not tried the Windows driver
at this point.
2.      Does anyone NOT use UTF-8 on their DB with anything above 7.6.04?
3.      Any comments?

 

Thanks a bunch in advance for your efforts!
