Issue/Introduction

How to Activate, Deactivate and test FASTPATH Checking.

 

 

 

Resolution

To activate FASTPATH checking for all users :
TSS ADDTO(anydept) IBMFAC(BPX.SAFF)
TSS PERMIT(ALL) IBMFAC(BPX.SAFF) ACCESS(ALL)

To deactivate FASTPATH checking for all users :
TSS ADDTO(anydept) IBMFAC(BPX.SAFF)
TSS PERMIT(ALL) IBMFAC(BPX.SAFF) ACCESS(NONE)

SAFFASTPATH can be enabled by permitting the OMVS acid access to IBMFAC(BPX.SAFFASTPATH). To implement this, do not give the STC acid associated with the OMVS started task the NORESCHK attribute. 

If enabled no SMF records are written from OMVS for successful HFS access improving performance and likewise, if disabled you will find SMF records written.  The SMF records are a way of testing that FASTPATH is working as you want it to.
