DBCNOEXTND, Unable to extend database xxx

DBCERTIFY Error: DBCERTIFY attempted to use MUPIP EXTEND to extend the database but the attempt failed.

Action: Examine the accompanying messages from the MUPIP EXTEND attempt to see why the extend failed. Some common causes for this are that $gtm_dist on UNIX or GTM$DIST on OpenVMS did not properly point to the currently installed V4 distribution, or there was insufficient disk space to perform the expansion.
