Dear All ,
Yes , System could be unlocked during Execution Phase of Upgrade using SUM Tool .
Many a times we come across situations when we require to login to the system during Execution Phase of Upgrade .
We wonder how can we do it during Downtime or Execution Phase .
Many of us also firmly believe that it is not possible to log in to the system .
But i say yes , we can unlock the system at two phases during Downtime .
To your wonder , even SUM itself does so . SUM unlocks and locks system automatically .
You can definitely check the 'SLOG' generated during this phase of Upgrade by SUM.
Well , the phases are :
- MAIN_SHDPREPUT/PREACT_UPG
- MAIN_SHDPREPUT/TABIM_PREPUT
If you want to login to the system during Downtime , you can set break point at above mentioned phases and proceed .
Do not forget to lock after that .
Command that SUM uses to unlock/lock as under.
