RE: How to upgrade SAP from ECC 6.0 EHP0 to ECC 6.0 EHP7 with database Oracle 10g ?
I would suggest to upgrade oracle to 11g first as 10g is no more supported. service.sap.com/instguides –>Database upgrade –> oracle
Make sure you have solution manager installed and configured to download the stack for your ECC6 EHP7.
Go through below guides: service.sap.com/instguides –> SAP Business Suite Applications –> SAP ERP –> SAP ERP 6.0 –> SAP enhancement packages for SAP ERP 6.0 –> SAP enhancement package 7 for SAP ERP 6.0
