SUM 2.0 and SUM 1.0 running in parallel on same server

[rdiger_hckel]

Hello,

I have a question similar to

https://archive.sap.com/discussions/thread/3822483:

On one iSeries server I would like to run two SAP BW upgrades in parallel:

1.) ABAP upgrade with SUM 2.0 (Netweaver 7.3 -> 7.5)

2.) Java upgrade with SUM 1.0 (Netweaver 7.3 -> 7.5)

For the ABAP upgrade I registered the SUM for SAP Host Agent as user QSECOFR with:

<SUM directory>/abap/SUMSTART confighostagent

and then started the SUM in the browser.

For the Java upgrade I registered the SUM for SAP Host Agent as user QSECOFR with:

<SUM directory>/STARTUP <SID>

and then started the SUM in the browser.

Is this the way to do it?

I'm not sure what happens to the library SAP_TOOLS as this was prpbably changed by the second registration...

Kind regards

Hello Rüdiger,

yes, you can go ahead and run 2 different SUM's even if they have different versions (in your case SUM 1.0 and SUM 2.0). The library SAP_TOOLS is only required to provide the needed tools to set the correct authorizations for the real upgrade tool library SAP<sid>UPG for ABAP or SAP<sid>UPGJ für Java systems. Later during the upgrade, SUM only uses the real upgrade tool library and in theory the SAP_TOOLS library could be deleted. The only conflict may occur if following phases run at the exact same time:

ABAP: PREP_INFRASTRUCTURE_OS4
Java: PREP-INFRASTRUCTURE-OS4

Both phases are executed in the very beginning of the SUM. Starting the second SUM after the first SUM finished this phase would lead you always to the safe side.

Maybe you want to know more IBM i specific details of SUM. So, please check also my other blog entry pointing to a recently published whitepaper about SUM on IBM i.

Best regards,
René
