SAP ERP 6.0 EHP 5 TO EHP7 UPGRADE-Shadow instance is not starting up



We have system with ERP 6.0 ehp 5 Kernel 721_EXT,OS LINUX RHEL 6.0,ORACLE

while upgrading to EHP 7 we have created mopz xml with kernel 741_Rel. Now at phase MAIN_SHDPREPUT/START_SHDI_PREPUT we are stuck as shadow instance is not starting up and when checked we found dispatcher is not running.

We have already set ssfs for the system.

Let us know as soon as possible as we can not proceed further

we are getting below error in DEVTRACE.LOG

I MtxInit: 0 0 0
