CA MIM Early Start Mechanism Considerations

If you plan to use the CA MIM Early Start Mechanism, consider the following:

• The Early Start Mechanism can be implemented one system at a time. However, until all systems are using it, full data integrity during IPL cannot be ensured.
• If CA MII is currently started with a command in a COMMNDxx member of SYS1.PARMLIB, you must remove that command from that member.
• If the CAMIMGR address space fails to initialize for any reason, such as a parameter error in the MIMINIT member, the IPL will not complete, because one or more system address spaces will be suspended by MIMESNQX. Attempts to start CAMIMGR manually after correcting the error on another system will also fail, because MIMESNQX has special handling for the ASID created via ASCRE. The only option will be to restart the IPL process from the beginning.
