XCOM for Windows 11.6.02 and 64 bit

[benamiy]

!Hello all!  Our open network team is gradually introducing Windows2016 servers. I realize that for these servers, XCOM 11.6.02 is required. But in the documentation, it says that XCOM 11.6.02 only supports 64 bit, and I am not sure if that is the case with our users (I am a mainframe person really). They only call the xcomtcp.exe from the server, or having the xcomd service respond to calls from the mainframe. Is that considered 64 bit? Regards, Yohai

Hello Yohai,

 

I am Shiva from CA XCOM Engineering team.  XCOM functionality and binaries (xcomtcp.exe, xcomd etc.,) remains same whether it is 64-Bit or 32-Bit.  On Windows or any other distributed operating systems, CPU/processor architecture determines whether system is 32-Bit or 64-Bit. One can run 64-Bit or 32-Bit applications On 64-Bit operating systems and can run only 32-Bit applications on 32-Bit operating systems.

 

Windows server 2016 is a 64-Bit operating system where you can run 64-Bit applications. XCOM r116 SP02 is a 64-Bit application and can be run on Windows server 2016 operating system. Please let us know in case you need any other information.

Hi Shiva,

Thanks for your prompt response.

In Upgrade from Service Pack 11.6.01 - CA XCOM Data Transport for Windows - 11.6 Service Packs - CA Technologies Documentat… 

I see:

Note: Service Pack 11.6.02 does not support 32-bit.

So I am wondering, can I be sure that xcom 11.6.02 will run on all our Windows2016 servers.

I do not want to maintain both 11.6.01 and 11.6.02

Thanks, Yohai

Hi Yohai,

 

Yes, XCOM 11.6.02 will run on Windows server 2016. It is certified on that platform.

Hi Shiva,

I downloaded XCOM 11.6.02

In the zip file, I see 3 iso files and 2 pdf files

:Unfortunately, none of the pdf files tells me what to do with the iso files

DVD500000000000425.iso

CDM09184137E.ISO

CDM08103840E.ISO

Please offer your advice

Hello Yohai,

 

 

Use CA XCOM DATA TRANSPORT FOR WINDOWS 64-BIT 11.6 SP02- PRODUCT PACKAGEDVD500000000000425.iso

and then follow very detailed instructions in the online documentation

https://docops.ca.com/ca-xcom-data-transport-for-windows/11-6-01/en/installing-and-upgrading

 

The other files are for the management center if you want to install that product.

Hi all,

I learned the hard way (that is, by opening a support case) that when "xcomqm -r" does not tell you if you are in 64 bit or 32 bit, that means you are in 32 bit, and an upgrade to 11.6.02 will not work. I think you should say that in the installation guide!

Hi Yohai,

 

Thank you for the feedback. 

 

Did you get chance to go through the "Review the Considerations" section before performing upgrade? 

 

It states the below: 

•  You can upgrade CA XCOM Data Transport for Windows 11.6.01 64-bit to CA XCOM Data Transport for Windows 11.6.02 64-bit only, but you cannot upgrade from 11.6.01 32-bit to 11.6.02 64-bit.

Reference: Upgrade from Service Pack 11.6.01 - CA XCOM Data Transport for Windows - 11.6 Service Packs - CA Technologies Documentat… 

• You can upgrade CA XCOM Data Transport for Windows 11.6 32-bit to CA XCOM Data Transport for Windows 11.6.01 32-bit, but you cannot upgrade from 11.6 32-bit to 11.6.01/11.6.02 64-bit.

Reference: Upgrade from Release 11.6 - CA XCOM Data Transport for Windows - 11.6 Service Packs - CA Technologies Documentation 

 

If you want to upgrade from 32-Bit version to SP02 64-Bit version, you need to uninstall older version and install SP02 64-Bit version. Make sure to backup the configuration files before uninstalling older version. 

 

Review the installation prerequisites here: Installation Prerequisites - CA XCOM Data Transport for Windows - 11.6 Service Packs - CA Technologies Documentation 

Installation instructions can be found here: Install in GUI Mode - CA XCOM Data Transport for Windows - 11.6 Service Packs - CA Technologies Documentation 

 

Once SP02 64-Bit installed, apply the customization from the files that you backed up from your previous releases.

Shiva

Hi Shiva

Yes, I went over this section over and over, trying to figure out what is my current situation, and hence, which path I should follow. That is why I started this discussion. The missing part, as I wrote, was that I was currently running 32 bit code.

Hello Yohai,

I just tried to reach you by phone for telling you that there is another solution to check if you ran a 32 bit or 64 bit version is to check the xcom registry path. Because the windows registry should not be touched normally I thought it is easier to tell you that you are on 32 bit version because the Installer does check it and does not continue because of 32 bit version.

• In Upgrade from Service Pack 11.6.01 - CA XCOM Data Transport for Windows - 11.6 Service Packs - CA Technologies Documentat… 

There is a Note: Service Pack 11.6.02 does not support 32-bit.

 

I hope this answer your question.

Hello Gerlinde,

I'd be interested to know where in the xcom registry path I can find if this is a 32 bit or a 64 bit version. The page, that is pointed by the link that you had provided, does not provide that information. 

Br, Yohai

Hello Yohai,

 

Please find the registry key details below: 

 

Registry key: HKEY_LOCAL_MACHINE\SOFTWARE\ComputerAssociates\XCOM

Value name: Bitness

 

If value is 64 (Hex 0x40) it is 64-Bit XCOM. If value is 32(Hex 0x20) then it is 32-Bit XCOM. 

 

Ex: From command prompt, issue command

"reg query HKEY_LOCAL_MACHINE\SOFTWARE\ComputerAssociates\XCOM /v Bitness"

 

You can see result as below: 

HKEY_LOCAL_MACHINE\SOFTWARE\ComputerAssociates\XCOM
Bitness REG_DWORD 0x40

 

This key is added starting from r11.6 SP01 onwards and you will not be able to use this way for older versions. 

 

Regards,

Shiva
