Error Messages
Library Procedure Error Messages
-1002 MESSAGE HPLOADCMPROCEDURE failed on CX'PCBXIMAGE
MEANING Internal error. This error is returned when DBOPEN calls
HPLOADCMPROCEDURE for CM CX'PCBXIMAGE and fails.
ACTION Notify HP support personnel.
-1003 MESSAGE Switch to NM failed on DBxxx, INFO
nn
SUSSYS
nn
MEANING The switch to Native Mode failed. DB
xxx
is the
TurboIMAGE/XL intrinsic. SUBSYS
nn
is the subsystem
that failed. INFO
nn
is the error number returned from
that subsystem.
ACTION Notify HP support personnel.
-1004 MESSAGE HPLOADNMPROC FAILED ON CM
intrinsic name
MEANING An internal error has occurred.
ACTION Notify HP support personnel.
-1025 MESSAGE XM Softlimit reached, only DBXEND/DBXUNDO allowed.
MEANING The dynamic transaction size exceed 28MB, program
should call DBXEND to and the transaction or call
DBXUNDO to rollback the transaction.
ACTION Make the transaction smaller or correct the application
that don’t call DBCONTROL mode 18. However, if
DBCONTROL mode 18 was not called and the transaction
size exceed 32MB, XM will abort the program.
