Informix

Hi,

We successfully done migration from version 11.70.FC4 to 14.10.FC11. Everything is fine on the "active" machine.

We are using "Active/Passive" configuration with: IBM PowerHA(HACMP).

The "mount" directory between two nodes is /informix. The installation was made on the "active" machine with $INFORMIXDIR=/informix.

When we moved "Resource Group" - on the second machine(Passive become Active) we receive a problem with "libisi.so.3" library.

We fixed this problem, after a couple a days investigation.

So, the questions are:

Do we need a IBM AIX GSKit installed on both machines before install Informix?

How can we bypass installation of Informix GSKit on the second(passive) machine without mounting the file system /informix and using $INFORMIXDIR/gskit/installgskit ?

Regards,

Hi,

Let me clarify the question:
Is there anyone in the world who works with: Informix 14.10.XXXX and IBM PowerHA SystemMirror(HACMP) on AIX 7.3 ?

Thanks,

Most Informix customers who need HA rely on the Informix HDR replication rather than OS HADR scripting.

Hi Boycho,

one thing to understand about GSKit is it's not an Informix thing.   It is brought by Informix, but might also be brought by other IBM products, and it installs into the OS, so not within Informix or whatever other product installation brought it, and it lives entirely under /usr/lib.

So yes, it should be installed into both HA OSes.

Also, it's not only used, by Informix, for SSL connectivity or Encryption-at-Rest and other obvious encryption stuff.  What you'll also need it for is any non-default Informix edition - without GSKit working your installation will always appear and act as Developer Edition.

Making sense, answering your question?

Thanks Andreas,

Yes, You are right.

I am trying to avoid double installation of IBM Informix GSKit on the common file system: /informix - mounted on Active/Passive machine.

My be the best solution is - BEFORE the installation of Informix on "Active" HA OS - we must have IBM GSKit already installed on both HA OSes(Active/Passive). After installation of AIX IBM GSKit on both machines - we will have the necessary libraries in /usr/lib. And after that we will have no problems with $INFORMIXDIR/libisi.so.3 on the second machine???

All the time I try to avoided execution of installation of IBM INFORMIX GSKit on the second machine (in the same mounted "$INFORMIXDIR=/informix" directory). It's a Bank Card System.

After the switch the package on the second node - we don't want to install again IBM Informix GSKit.

Thanks,

It's not "IBM Informix GSKit", but simply "IBM GSKit" - it's not anything Informix specific.

Also you'd not even be able to install it under /informix as it will go to the OS libs.

What the Informix installer does is it unpacks the packages under $INFORMIXDIR/gskit and runs the contained install script which, if a GSKit installation already exists and isn't older than the one about to be installed, would immediately clean up, exit and do nothing.  If it has to install, it will do so using OS install routines, completely disregarding anything "Informix".

You can do this GSKit unpacking and installation separately to make sure the GSKit is present on the node where you haven't ran the Informix installation.

HTH,
