Upgrade in MODPROF_UPG phase


Hi SAP Experts,

We are upgrading from 4.6c to ECC6 EHP3. In Upgrade we reached the stage called MODPROF_UPG in which after downtime it starts the system automatically. But somehow it is not able to bring the system UP.

While diagonising the situation, we came to know that there are 2-3 parameters which it looks upon like -


ipc/shm_psize_10 = 1196000000

ipc/shm_psize_40 = 916000000

We also checked the profiles by sappfpar check pf=./<profile>, the result shows that the size of ipc/shm_psize_10, ipc/shm_psize_40 is small, so we increased it according to the suggested and repeat the phase but still got the same error.

We also changed these parameters and try to start SAP manually and it started but we are not able to login as it shows the error "SAP License Install check failed"

We observed that while running the phase MODPROF_UPG it rewrites these profile parameters as the intial value and because of that it is not able to bring the system UP.

Can you please let us know what do be done at OS level to get that error free?

Earliest help in resolving this will be highly appreciated.
