Error Messages
Utility Error Messages
MESSAGE MOVE OF FILE
x
NOT ALLOWED: FILE IS NOT CORRECT TYPE (FILE
CODE
#
)
MEANING The file specified is not a database file.
ACTION Try the MOVE operation again with the correct file name.
MESSAGE NO MANUAL ENTRY FOR DETAIL ON PATH
#n
MEANING DBLOAD is attempting to load detail data set entry n, which is the number
of the detail data set path referencing the manual master in question.
ACTION Add entry to manual master with application program or QUERY. Run
DBLOAD again.
MESSAGE PROCESS TABLE OVERFLOW
MEANING At some point more than 180 processes were logging at the same time.
ACTION Notify your database administrator and HP support personnel.
MESSAGE RECOVERY TABLE IS FULL
MEANING Internal error.
ACTION Contact your database administrator.
MESSAGE RECOVERY TABLE OVERFLOW
MEANING You tried to specify more than 100 user recovery files.
ACTION Reduce the number of recovery files needed.
MESSAGE RECSIZE MUST BE <=
xxxx
AND EVENLY DIVISIBLE BY 256.
MEANING Issued if the REC=recsize parameter for DBSTORE specified a record size
not modulo 256 halfwords, or greater than the configured record size of the
device.
ACTION Check the REC=recsize parameter and correct it before running DBSTORE
again.
