The PLOAD_SHMAT environment variable

If the pload converter thread cannot attach to the passed address, you receive a message that asks you to set the PLOAD_SHMAT environment variable.

When you set the PLOAD_SHMAT environment variable, the pload converter calculates the address by using a global attached segment list that is maintained across pload virtual processors. The pload converter attaches at the next available address after the highest address on the list, ensuring that the converter always attaches to an unused shared memory segment.
