Work Processes fail to connect to the database with error
CoCreateInstance failed. rc: 800703fa.
Please note that the error code 800703a can only be found in the developer traces of the affected work processes and is neither included in syslog nor in ABAP dumps.
Still, due to the failed connection attempts you might additionally see:
- Dumps in transaction ST22:
Runtime Errors DBIF_RSQL_SQL_ERROR
SQL error in the database when accessing a table.
- Errors in the Syslog (transaction SM21)
***LOG BY2=> sql error -1 performing CON
***LOG BY4=> sql error -1 performing UPD
***LOG BY4=> sql error -1 performing PRE
This KBA only applies if the developer traces show that the connection attempts fail with:
OpenOledbConnection : CoCreateInstance failed. rc: 800703fa.
failed to establish conn
To verify this, open the developer trace of an affected work process in transaction ST11 and look for
CoCreateInstance failed. rc: 800703fa
