The new FSACCESS control option lets you enable or disable FSACCESS resource class checks that originate from the SAF component.
The FSACCESS IBM z/OS feature added a security check for the FSACCESS resource class to verify user authority to access the file system objects on z/OS UNIX zFS. This support was added by IBM APARS OA35970/OA35974 at z/OS 1.12 and is included at base z/OS 1.13.
With the IBM feature installed, the resource class checks occur by default many times, so disabling the calls can help significantly reduce overhead.
Note: For a complete description of the FSACCESS control option, see the Control Options User Guide.
Control option PWADMIN is now available to enforce NEWPW control option restrictions and password interval restrictions when authorized administrators or users perform a password change through a TSS command. The required authorization is MISC8(PWMAINT) or ACID(MAINTAIN) authority.
A mirror security file is an exact duplicate of the primary security file and provides up-to-the-minute data in the event of a sudden problem with the primary file.
Important! Mirror files are supported only on systems that do not share the security file (SHRFILE(NO) control option setting).
You can use CAKOJCL0 members VSAMDEFM and TSSMAINM to accommodate your site's needs when setting up the mirror file; you can activate mirroring through the MIRROR control option.
