The following OCMC Logger info messages may be encountered on a new Historian Server:
SYSPERFDATAIMPORTTHREADCOUNT
Tag not found
SYSPERFDATAIMPORTHANDLECOUNTCross-node encrypted SuiteLink requires both nodes to be joined to the same System Management Server (SMS) server. In some cases, even if SMS is properly configured, a system may encounter the following error and the encrypted SuiteLink connection will fail, even though a Troubleshooting Scan within the AVEVA Common Service Portal may return without errors.
...This Tech Note details the procedure to identify and clear APPCRASH events that appear in the Windows Event Viewer for System Platform components.
...It may become useful to test connectivity to a local or remote SQL Server to verify the connection, or credentials in use. This document was designed to explain the process of testing the SQL connection using a common, and non-software specific method.
...This Tech Note provides examples of how to derive different SQL Server date value such as the first day of the month, the first day of the week etc. These examples may become useful while developing Wonderware Historian reports (for instance: "average flow month to date", "total yield this quarter" etc.).
...When working with Wonderware Historian and IDAS, it is important to take time into serious consideration. With IDAS historical data storage there is a term called the "Real-Time Window", which is a period of time behind and ahead of the Wonderware Historian system time, where values coming into the system are considered "valid" and will be stored properly. With Wonderware Historian the real-time window can be any value coming into the system between -30 seconds and +999 milliseconds. Time offset and discarded data can be a result of improper time synchronization. The purpose of this document is to help identify...
It may become necessary for a developer to create an IDAS in AVEVA Historian that views many data points without having an InTouch HMI application to import tags from. This document provides the procedure necessary to utilize the Import Tags feature of AVEVA Historian without an existing InTouch application, as well as how to use the Historian Server database export/import utility for archiving or troubleshooting.
...The Wonderware Historian (IndustrialSQL Server) includes two features that allow performance statistics to be collected and distributed to network clients. The System Driver module performs the task of collecting historian performance statistics and the InSQL IOServer (INSQLIOS) allows clients to connect via Suitelink to acquire real-time data. Using these two features we can acquire historian performance statistics to clients such as Wonderware Industrial Application Server for real time monitoring and alarming.

...When experiencing problems connecting to a Wonderware IndustrialSQL Server Historian (InSQL) from a Wonderware ActiveFactory client such as Trend, there are several steps that can be used to troubleshoot the problem. This tech note details the correct steps to take to initiate communication. It is assumed that there is a running InSQL Server on your network which is able to accept client connections from other client nodes.
