Use this option when you want to run Single User using the OPTION2=Y_SU option with CXXMAINT or to remove support for Single User using OPTION2=N_SU. This option is provided to the full CXX report and has been added to the DB00271I MUF startup message (for details about DB00271I, see the CA Datacom/DB Message Reference Guide).
The new Single User option is provided to the full CXX report as follows:
SECURE USING JOBNAME - NO CXX LEVEL - 1 SECURE ALLOWING SINGLE USER - NO SINGLE USER ALLOWED - NO
We have long recommended against using Single User mode. The Single User environment allows no logging and therefore has no restart or recovery capability. In addition, running in Single User bypasses external security. However, CA Datacom continues to support using Single User mode for the DBUTLTY functions that run Single User and the DBFLSUB feature that loads an area with user program input. Previously, only if the CXX was externally secured did you have the option of using DBUTLTY CXXMAINT OPTION=ALTER,SINGLE=YES to allow Single User mode, or SINGLE=NO to block Single User mode.
If a Single User open that is allowed occurs, message DB00138I is issued, confirming that fact and documenting the Single User execution (for details about DB00138I, see the CA Datacom/DB Message Reference Guide).
