Patching Web Dispatcher?

[Former Member]

Hi,

Web dispatcher download/installation (importing?) info at

http://help.sap.com/saphelp_nw2004s/helpdata/en/7c/6bf41aca84425196bd358df965fe3e/frameset.htm

is misleading, it lists SAPWEBDISP_<PL>.SAR as the latest Web dispatcher version, and mentions that DW_<PL>.SAR naming was used for older versions.

On the https://service.sap.com/patches sapwebdisp_0-20000961.SAR (patch level = 73) is older than dw_88-20000961.SAR (patch level = 87, not 88).

In order to patch older version of Web Dispatcher do I need to uninstall older version, and if so does uninstalling means deleting Web dispatcher directory?

Thanks!

Rob

Hi,

I do not think there is any miscommunication here, what they mean is that in the older model of patch delivery, the sap web dispatcher was bundled in your DW car file , however now it is shipped seperately as sapweb*.sar.

Hi Siddhesh,

I would like to use the latest patched version of Web dispatcher.

If what you are saying is correct, I then need to download sapwebdisp_0-20000961.SAR file from http://service.sap.com/patches site?

What I'm confused about is why the file dw_88-20000961.SAR has newer timestamp and higher patch level.

If dw naming convention was part of older patch delivery, wouldn’t sapwebdisp_0-20000961.SAR be the newer file with the latest patch?

I'm obviously missing something here, thank you for taking time to try to clarify this.

Hi Robert,

Take a note at other patches alongwith the dw.sar file, you will see that they are not all at same patch levels.

the normal way of patching kernel is :

we apply

sapexedb

sapexe

rest of the patches...

this way we ensure that we are on the latest patches on all fronts... it is normal to have the sap kernel (disp+work) and other sap executables to be at different patch levels.. take the case of R3trans and TP they both would be following a different release strategy.

so it might be that SAP has now decided to seperate the sapwebdispatcher.. just like tp and r3trans !

if you are concerned that dw might contain a latest version of sapweb dispatcher..extract the contents of dw to a seperate directory using

sapcar -xvf dw.car -R <DIRECTORY OF YOUR CHOICE>

and then do the same with sapwebdispatcher.sar file...

view the contents of both directories and see which one has the latest version and use the latest one.

I doubt that dw will contain a more latest version of sapwebdispatcher.. in fact i doubt that dw.sar would contain any version of sapwebdispatcher.. if it does.... pls update this thread so that even i get to share your knowledge maybe we would raise this to SAP

hope this helps,

Hi Siddhesh,

If you read my first post "sapwebdisp_0-20000961.SAR (patch level = 73) is older than dw_88-20000961.SAR (patch level = 87, not 88).". I got patch levels by extracting each sar files and checking the version.

I'll go with patch level 87 and hope for the best.

I'll also assume uninstalling Web Dispatcher means running UninstSAP.exe that is under Web Dispatcher installation root.

Hi,

I am wondering whether sapweb dispatcher executable was present in the dw.SAR file ?

Hi,

That is strange, if I were you , I would post a message to SAP if i am doing this on production system to minimize the risk.

Hi Robert,

I recently patched a kernel , i have used the DW.SAR for sapwebdispatcher instead of the seperate file.

It works well.
