we have initiated SAP CRM EHP3 upgrade and started the activity and in preparation phase we got a issue with ops$ mechanism which required us to set up the SSFS configuration to connect database Oracle11g with Sap kernel 740.
after that the preparation continued and in phase PREP_IMPORT/TOOLIMPI it took long time and we waited for 10hrs and then we have stopped the process and cleaned SUM and restarted SUM tool with fresh dump.
again its taking long time in PREP_IMPORT/TOOLIMPD phase.
in the Log folder of SUM not file is getting updated and in temp folder only one file dev_evt is updating with time stamp only not data is being updated in the file.
Kindly suggest experts.
