Good morning everyone.

I have a IDS 11.5FC5WE installed on Red Hat 6 Linux. I don't want to use
AFFINITY resources and I dont know how to avoid.

My VPCLASS ONCONFIG parameters

MULTIPROCESSOR 1
VPCLASS cpu,num=4,noage,aff=0
VP_MEMORY_CACHE_KB 0
SINGLE_CPU_VP 0

Linux commands output

I have two questions:

1 - How many CPU do I have to consider to set the cpu VPCLASS ? 4 ? 16 ? 120 ?
2 - How can I disable AFFINITY PROCS on IDS 11.5 ?

Thansk a lot

IDS 11.70 in RHEL6.4 , like to upgrade to RHEL 7.x

I have the IDS 11.70 in RHEL6.4 x86_64 running well ,
the problem is RHEL6.4 g++ is 4.4.7 , which only support
c++0x , not c++11 , so I like to upgrade gcc to 4.82 ,
I am not good at g++ upgrade , so I might like to upgrade
RHEL to 7.x with default gcc version 4.82 !!!

I never use IDS 11.70 in RHEL 7.x before , I like to know
what should I take care to upgrade RHEL6.4 to RHEL7.x ,
Still IDS 11.70 running fine ?!

Any comments are great appreciated !

Need help on re-directing errors to db

December 14, 2015, 11:48 pm

HI Friends,

We are planning run a program in background without messages to TTY....so we
are trying to insert errors to tables....

Actually program is having transaction.....on any error I think it is
roll-backing data as we are unable to see data in error table defined.

In error function actually there is no rollback work specifically...but

database client
begin work....

if any error
call l_exit_program(1, scratch)

function l_exit_program()
-- write new code to send error to db....
-- Unloaded data to a file from table...unloaded row well..

whenever error continue

close database

whenever error stop

exit program(1)
end

But after program run unable to see record in db errr table....

So how record was rolled back without "rollback work" statement ?
Is it because of "close database" statement ?

How can we insert errors to db even though transaction is there......baseline
functionality should not change with this new process of running background
and sending errors to db....

Kindly help us...
Thank you,
Hyma P

Hi,

I have a query regarding informix database that we are using for our
product.Informix database is taking 15 minutes to get connected and this
behaviour is consistent. It looks like the new password is not getting updated
in the DB. Is this behaviour from the informix Db side ? Is there any
parameter that specifies the password to be synched ?

Thanks,

Hi,

We are using Informix database and would like to post query regarding a
behavior observed recently.

For the user after changing the password it takes 15 minutes to log in to the
interface . From our analysis it looks like password synch is delayed or
configured to synch every 15 min and would like to know if it is a specific
behavior of Informix database.

Is there any configuration parameter which sets synch time specific to
Informix ?

Thanks,

Siddharth Ravindran

Scanning barcode spcial character on informix form

We are stuck at one issue in informix 4gl would be very gratefull if somebody
can help. I am using the informix 7.3 version. Issue is :- we have to read one
barcode which has some kind of delimiter (010732571000136311150630214628^]301)
before 301 value. When i scan the barcode on the informix form it only shows
as (010732571000136311150630214628301) without the ^]. but if i scan it on vi
editor and then copy paste it on informix form it works? wondering why it
doesn't show when we scan directly from the Rf gun.

We have the requirement to scan the barcode and since it's not showing up the
parsing code with delimiter we are stuck.

Hi,

We are trying to drop a database in informix. And we are gettting below error:
425: Database is currently opened by another user.
107: ISAM error: record is locked.

Before droping database we have changed the informix to administrative mode
using onmode -j -y.
However when we ran onstat –u, shows no session to external user other than
informix.

Any help on this will be appreciated.

Thanks.

Good day Informix gurus,

I am looking for help polishing off a configuration with our new IDS instance.

O/S: openSUSE Leap 42.1
IDS: 12.10.xC7

User authentication has been configured so that most users get authed against
the AD.

I can't seem to figure out what needs to be done so that my configuration
authenticates user logins successfully.

I am including the following file excerpts from the different configuration
and log files related to this situation:

*** Excerpt from $INFORMIXDIR/etc/$ONCONFIG file:

received for user entrepot: 10 (User not known to the underlying
authentication module)
2017-05-15T15:00:04.657913-04:00 phoenix2 oninit: pam_unix(informix:auth):
authentication failure; logname= uid=1001 euid=0 tty= ruser=entrepot
rhost=cantrexbi.cantrexnw.local user=entrepot

I believe that I have tried many combinations so far and I can't seem to
determine why AD users are denied access when connecting through a
client-server connection.

SSH connections work fine (even though they get authenticated through AD and
SSSD but I can't seem to find the right settings to get the Informix PAM
connections working.

Any help would be greatly appreciated.
