TL Level – CL 5.6 on AIX 5.3

[David Teh]

Hi folks,

I’d like to know what is the highest TL level that your AIX 5.3 has running without issue with CL 5.6.

TIA!

One and All,

We have been running CIS5.6R2 on AIX5.3 TL11 for over a year without any issues or problems.   Cloverleaf Integrator runs in a dedicated LPAR on its own physical server – no other applications run on its server.

From what I understand:  Healthvsion/Lawson certifies the Integrator on the minimum TL (maintenance) level on an OS so you can usually up the level without issue, that is, the Integrator will continue to run on a higher level for that OS version.

At least that has proved out for us so far.

Happy Labor Day!

One and All,

Just another item about why we are running at AIX5.3 TL11:  IBM pulled support on TL8 back in April 2010 and our Operating System Group pushed us to up the level to an IBM supported maintenance level.

Enjoy.

That probaly means we are about to be pushed up ourselves.

You said you are running at AIX 5.6 TL11 and I would also like to know the SP level if you know that information; otherwise, just run my posted script or the “oslevel -s” command to see.

I already passed along to our system admin group the TL11 information.

Russ,

Per our >oslevel -s

Hope this helps you guys out.

What level has Lawson certified for CL V5.6 rev2?  When they say they have certified say AIX 5.3 TL8, does that mean up to TL8  or does that mean TL8 and above?

I would hate to upgrade unless they had specifically said it’s “certified”.

[Bob Richardson]

One and All,

I have gone through this cycle of “certification levels” with Healthvision support before we upgraded.  Per support they certify at a minimum OS level and the theory is that the minimum and above on that OS is de facto certified to be good for the engine.

So far this has proven out in our experience AFTER running our Test engine on the higher levels for at least a month prior to upgrading our Production servers.  In most cases our issues in the past have been with the hostserver module but that has stablilized since AIX5.2 for us.

If in doubt I would suggest a call to support to confirm my assertions.

Enjoy.

Robert:

Thanks for providing the output of the “oslevel -s” command.

I’ve informed our system admin group that you are running Cloverleaf 5.6rev2 on AIX 5.3 TL11 SP2.

Kevin:

The last time I called Cloverleaf support to see what level of the OS was supported it seems to me they said they don’t certify beyond the base level they used originally.

If this has changed, then I would definitely call tech support and go with that; otherwise, questions like this on Clovertech have been additionally helpful.

I had called clovertech support when I went to AIX 5.3 TL8 SP8 and wasn’t given any assurance my OS upgrade was certified beyond the base level they originally used to certify Cloverleaf 5.6rev2 on, which was lower than what I upgraded to.

I would of been glad to stay with waht was working fine but as the OS levels go out of support we eventually receive a mandate to upgrade to an OS that is supported.

I passed along what you said below to our system admin group:

I asked our system admin group if I could expect a simialr push to upgrade our OS and here is the response I got from them:

Support for AIX 5.3  TL 8 has not been pulled.  In fact, they are still coming out with service packs.  Support should continue a year after the last service pack is issued in a month or two.  IBM typically has a two year cycle limit for maintaining a TL.  Since TL 8 came out in April 2008, normally, fixes would not be added after April, 2010, but that appears to be extended.  There is an additional year of support after the last service pack so even with the original schedule, TL8 would have been supported until April 2011.  Three years is the absolute limit we should be on the same TL in most cases.

Russ,

Thanks for your research and reply here.

Guess our Operating System Group went ahead not knowing that IBM

extended support for TL8.

So far CIS5.6R2 is running fine on TL11 SP2.

We will be looking to up the OS to AIX6.1 next year.

Our sys admin wants to upgrade to AIX 5.3 TL12.  I called support to see what level of 5.3 is “certified” and they told me that they don’t certify TL’s, that only the base 5.3 is certified.   They did say they would support us if we upgraded.

Is there anyone out there who is at AIX 5.3 TL12?  And if so, what’s been your experience?

Thanks.
