Issue/Introduction

HFS file security with TSS is not working after setting HFSSEC(ON).

Resolution

The following needs to be installed:

1. ENF/USS function of Common Services: CCQ9E10
2. Enable the CAIENF/USS event intercepts adding the CARRDCM0 DCM in a DCM statement in the CAIENF configuration member ENFPARM
3. Stop/restart ENF with the COLP option: S ENF,,,COLD
4. For best performance define a new object to VLF (Virtual Lookaside Facility). To define a new object to VLF, add an entry to the COFVLFxx member of SYS1.PARMLIB, where xx is the VLF identifier that your systems programmer assigns.

            Example: Define a New Object to VLF

             CLASS NAME(CAENFU) /* ENF/USS pathname lookup cache*/

             EMAJ(PATHCACHE) /* Required major name*/

            MAXVIRT(512) /* 512 = 2MB*/
