Documentation
Definition
Setting this flag affects what happens when an open database connection is lost due to a database failure or lost network connection.
Regardless of whether the flag is set, the work process tries to restore the lost connection. If this is not possible, the following happens:
DB-RECONNECT-TYP is not permanent (DBCON_RECO = BLANK):
The failure is ignored and the system starts the requested transaction. However, if the transaction needs the non-existent connection, it terminates.
DB-RECONNECT-TYP is permanent (DBCON_RECO = X):
After the connection is first lost, the system checks before each transaction call whether it can be restored. If this is not possible, the transaction is not started, regardless of whether it needed the special connection or not. The SAP system will only work when all permanent database connections have been restored.
You should set the flag if the database connection is essential, or when it is accessed very often.
When you start the system, the default connection has the implicit database reconnect type "permanent" (DBCON_RECO = 'X'), even though it does not appear in the table DBCON.
