Choose the main configuration of the tool. You can adjust the detailed settings on the next screen.
01) – Single System (longer downtime, no shadow instance or shadow instance running exclusively)
02) – Standard (standard downtime optimization, moderate resource assignment)
03) – Advanced (extensive downtime optimization, higher complexity, high resource assignment)
Keep archiving on during the whole procedure
Switch on expert options
In the next screen, there are many options, i kept them as it is(default), but dont know what to select here:
If you are running dialog instances (additional application server instances), decide if they should be updated.
Otherwise, they are only stopped and not restarted.
Update Dialog Instances – Yes or No ??
We have a dialog instance and it is stopped. I thouht the dialog instance will also be upgraded if central instance is upgraded.
Need your help.
From SUM Guide:
Update of SAP Systems Using Software Update Manager (ABAP+Java Systems)
5.3 Starting the Software Update Manager Prerequisites× Enhancement package installation or SPS update: All application server instances and their associated services are up and running. Only valid for Source release =SAP Netweaver 7.0,EHP1,EHP2and 640~~~~
Release upgrade only: You have uninstalled all additional application server instances.
To uninstall the additional application server instances, proceed as described in the installation guide for your source release. If you want to use the profiles of the additional application server instances to adapt the profiles of the target system, save them before you uninstall the additional application server instances.
However there is no additional steps required for only ABAP system- Refer to :
Update of SAP Systems Using Software Update Manager (ABAP Systems)
In this guide you can also refer to
5.18 Isolating the Primary Application Server Instance
to know how the upgrade tool handles the different application servers.
Previously the additional servers need to be installed post upgrade using SAPINST.
The option ‘update dialog instance’ will shut down the DIs before downtime starts and – yes – SUM will update the dialog instances during downtime there are some extra phases that will take care of that.
If you want the tool/SUM to handle this, please go ahead and select the option and proceed.
