Is the value of the CA OPS/MVS GLOBALTEMPMAX parameter important to calculate the space required by SYSCHK1 DIV VSAM dataset?
The length of the global variables and the device type of the volume where the SYSCHK1 DIV VSAM dataset is allocated are factors related to the size of the file.
The GLOBALTEMPMAX has no bearing on the size of the SYSCHK1 DIV VSAM dataset because this parameter only controls the number of temporary variables. Those variables are kept in storage only so they are not written physically to the SYSCHK1 DIV VSAM dataset.
