Update Web Dispatcher

[Private_Member_19084]

Hi experts,

I would like to update a webdispatcher.

OS is windows 2003, x64, SP 2

Current Version is 7.11.0

kernel release = 711

How do I have to do this?

I've already downloaded sapinstgui7202_17 and sapwebdisp_618.

But do be honest, I am not sure if this files are correct and suitable.

Next thing is, that I don't know exactly how to patch it.

Is it a big deal?

Kind regards

Nopes, not a big deal.

It easy, you should have searched it on scn or google.

Thank you for the help.

You take the backup of your folder. Stop sap services and uncar the webdispatcher sar file in it's executable location

Refer my 2nd link.

Hi all,

I did the following now.
I unpacked .sar file (uncar).

Then I did exchange the old content with the new one and also the config-file.

But after starting the webdispatcher-service again I get the following error:

[divyanshu_srivastava3]

What version has you used ? replace your config file with the one you have backed up.

Run this command: sapwebdisp pf=sapwebdisp.pfl -checkconfig

Divyanshu

[Private_Member_19084]

Hello Divyanshu,

I already did use the old config file.

I tried the following in cmd:

sapwebdisp.exe pf=<config.txt> -checkconfig

But I get the output "The system cannot execute teh specified program"

[divyanshu_srivastava3]

Can you go in the directory and run this again.

Which sar file have you useed ?

[Private_Member_19084]

Run what again?
I had been in the directory, of the new one.

Thats the sar file:

sapwebdisp_618-20004013.sar

[divyanshu_srivastava3]

Stop the service from services.msc.

Kill all web dispatcher process including startsrv.

Refer: 552286 - Troubleshooting for the SAP Web Dispatcher

for how to do it.

[Private_Member_19084]

Hi,

I will try it, but before, in processes I can't see startsrv.

Should I try it also?

Hi Christian,

As per the note: 908097 - SAP Web Dispatcher: Release, Installation, Patches, Documentation

"SAP Web Dispatcher is downward compatible. You can use any supported version that is greater or equal to the kernel version of your backend system. SAP Web Dispatcher version 7.20 is also upward compatible with all 7.2x kernel versions. The SAP Web Dispatcher versions 7.20, 7.40 and 7.41 can be downloaded from the SAP Software Download Center as described below."

And yes, please check PAM for compatibility.

Hello Divyanshu,

thank you very much again.

I already tried PAM, but couldn't found anything regarding WebDispatcher.

Kind regards

[divyanshu_srivastava3]

No problem, guide and notes are always handy + sufficient.

Cheers,

Divyanshu

[Private_Member_19084]

he one last question - promised

At this link https://websmp210.sap-ag.de/~sapidb/011000358700000877232012E

Page 24 I can't really follow.

Which file-systems are required now?

/usr/sap/<sid>

/usr/sap/trans

Is this enough?

What about the sapmnt, will this be shared automatically at installation?

Kind regards

[divyanshu_srivastava3]

As per the guide, you need both.

However, I don't think or have seen trans usage.

And create the share manually, let the installer do the rest.

Divyanshu

[Private_Member_19084]

yes, I also doubt that the trans will ever be used.

he once again a big thank you
