During system initialization, the system issues this message asking the operator to specify whether the normal master catalog or an alternate master catalog is to be used by the system. If the catalog name to be used has been provided in the LOADxx member, but that member name cannot be found in SYS1.NUCLEUS, this message is issued.
The system waits for the operator to reply. The system generates the name of the SYS1.NUCLEUS parmlib member that is used to find the master catalog. If the parmlib member cannot be found, the message is reissued. If the SYSCAT statement is supplied in the LOADxx member and this message appears, either the name of the catalog is spelled incorrectly in the SYSCAT statement, or LOADxx filtering parms (such as, HWNAME and LPARNAME) might be incorrect, causing the system to attempt to use the wrong master catalog name.
