Implementing Ownable Resource Security › Virtual Reader Protection

Virtual Reader Protection

The VMRDR keyword lets administrators control who can put files into whose virtual reader. For instance, the CMSBATCH virtual machine’s reader might otherwise be unprotected from a security standpoint.

For example, the following command prevents a user from punching a file to CMSBATCH:

TSS ADD(PROFRND) VMRDR(CMSBATCH)

From a security standpoint, the key to implementing VMRDR security is to remember that VMRDR lets the ACID holder place spool files in the specified userid’s virtual reader.
