WCCILdata - SYS/SEVERE - Database error, PersObjectNameText, store

Enclosed you'll find the explanation for a set of log-messages which can occur during runtime when trying to create a datapoint. The log-message is written to the PVSS_II.log-file

WCCILdata (0), 2014.10.31 10:30:35.908, SYS, SEVERE, 69, Database error, DataManTask, dbError, RAIMA Database Error *** Code:-901 (INTERNAL error: -901
bad dchain
C errno = 0: No error
FILE: ..\..\..\..\workspace\ExternLibs\rdm45\runtime\Dio.c(2270))
WCCILdata (0), 2014.10.31 10:30:35.909, SYS, SEVERE, 69, Database error, PersObjectNameText, store


Log-message with symbolic names:

WCCILdata (0), <TIMESTAMP>, SYS, SEVERE, 69, Database error, DataManTask, dbError, RAIMA Database Error *** Code:-901 (INTERNAL error: -901
bad dchain
C errno = 0: No error
FILE: ..\..\..\..\workspace\ExternLibs\rdm45\runtime\Dio.c(2270))
WCCILdata (0), <TIMESTAMP>, SYS, SEVERE, 69, Database error, PersObjectNameText, store


The log-messages describes that some information in the database cannot be stored and therefore the datapoint is not created. At the first message the information “bad dchain” gives an indication how the problem can be solved.

To get rid of this problem you have to perform the following procedure:
-- stop the project
-- create a backup for the RAIMA-database (excluding the VA-directories)
-- open a command shell
-- change into the directory <WinCC OA project>/db/wincc_oa
-- start the command
<WinCC OA installation>/bin/dchain TypeAndId
-- wait until this process is finished
-- start the project

Afterwards you can check if the problem is gone when a new datapoint is created.

If this didn’t solve the problem please get in contact with your common WinCC OA support.
