Troubleshooting
Troubleshooting
Common error codes and troubleshooting methods
What can I do if full data migration stops or slows down?
What can I do if incremental data migration or synchronization is delayed?
What can I do if DTS fails to obtain the schemas of the source database when I configure a task?
What can I do if the message "Instances with internal IP addresses are not allowed" appears when I test connectivity?
What can I do if an error message indicating insufficient resources appears when I configure a task?
What do I do if a connection failure occurs when I configure a task?
What can I do if data loss occurs in the destination database due to inconsistent case sensitivity of character sets in the source and destination databases?
What can I do if data loss occurs in the destination database due to online DDL operations performed in a table merging task?
What can I do if data loss occurs after I perform two-way synchronization among three instances?
Precheck failed
What can I do if the message "The source database account does not have the sysadmin permission" appears?
What can I do if a task fails to pass the precheck "Multiple Usernames for One Instance"?
What can I do if the DTS instance cannot connect to the source or destination database?
