Wonderware Historian Configurator ArchestrA Reporting 中設置 Alarm Data Source for Sample Reports 時， 會出現的異常，百度誤解，google 搜到了對應解決方案。
Unable to create WWALMDB with the Alarm DB Logger, says the login failed.
Problem
Trying to create a new Alarm Database on a new system, but the test connection and create databases fail saying that the login failed.
Product Version: 10.5
OS: Win 2008 32 bit
Solution
The SQL Server had been installed using the default settings. As such it was setup to only allow Windows Authentication, and not SQL Authentication (aka Mixed mode) as required by the Wonderware products. To fix this, logged into SQL MAnagement Studio using Windows Authentication, then right clicked on the server name in the tree and went to properties. Under security we set the server to use SQL Authentication and Windows Authentication. Then hit OK. Then under the Security> Logins section, we right clicked on the sa account and first entered a new password. We then went to the Security section on it and under Login set it to enabled. Once this was done, we right clicked on the server name at the top of the tree and selected Restart. Once this finished the Alarm DB Logger wa able to connect and create the database correctly.
