- Enter the authentication information. Specify the authentication method SQLCheck will use to connect to the server and the database. You can select either Use Windows Authentication or Use SQL Server Authentication. If you choose to use SQL Server Authentication', you must enter a valid SQL Server login id and password. These credentials are encrypted before they are saved.

- Application errors that occur while in screen saver mode are written to the event log.

| Technical Questions |
|
|
| |
| What are the system requirements and prerequisites for SQLcheck? |
SQLcheck requires one of the following 32-bit operating systems:
- Windows 2000 Professional
- Windows XP SP2 or later
- Windows Vista Business or Enterprise
- Windows 2000 Server SP4 or later
- Windows Server 2003 SP2 or later
- Windows Server 2008
SQLcheck is best used on 24-bit color displays with a minimum resolution of 1024 x 768. The essential elements of the dashboard will fit on an 800 x 600 display, and the product will function in a 256-color environment; however, appearance will be affected in both cases. |
| |
| What Windows security permissions are required? |
| The account you use to run SQLcheck should have administrator privileges on the database server computer. If your Windows account does not have these permissions, SQLcheck may be unable to display all available data. |
| |
| What SQL Server security permissions are required? |
| Idera recommends using the Windows Integrated Security feature of SQL Server. However, SQLcheck supports both Windows Integrated Security and SQL Server native security. The account you use to run SQLcheck should have "sa" privileges in SQL Server. |
| |
| What versions of Microsoft SQL Server can be monitored with SQLcheck? |
|
SQLcheck supports monitoring the following 32-bit and 64-bit (x64 and Itanium 2) versions of Microsoft SQL Server Standard or Enterprise editions:
- SQL Server 2000 SP4 or later
- SQL Server 2005 SP1 or later
- SQL Server 2008
|
| |
| What steps should I take if SQLcheck is unable to connect to a particular server? |
STEP 1:
Please check the following items:
- Ensure that the name of the database server is correctly entered.
- The account that which SQLcheck uses to access the database server computer must have Windows administrator permissions on the database server.
- The account that which SQL check uses to access the SQL server must have System Administrator (sa) privileges on the SQL Server instance.
- The database server must have the Remote Registry service enabled and started.
- Ensure that the port that SQL Server is running on (default of 1433) is not blocked via a firewall, router, etc.
STEP 2:
Once the criteria above have been satisfied, please verify the database server can be "seen" from the SQLcheck machine.
- Go to Start>Run>CMD (Enter).
- Type "ping SERVERNAME" (Enter).
If the ping is successful, the database server can be "seen" from the SQLcheck machine. If is it not, consult with your Network Administrator in order to make the server available over the network.
STEP 3:
Please use Performance Monitor to verify that the database server is returning data.
- Go to Start>Run>Perfmon (Enter).
- Right-click the graph area.
- Click "Add Counters..."
- Click the "Select counters from computer:" radio button and enter the name of the server you are trying to connect to (i.e. \\SERVERNAME).
- Click the "Performance object:" drop-down list and select "SQLServer:General Statistics".
- Click the "All counters" radio button.
- Click "Add" & then "Close".
If data is returned in the Performance Monitor application, then the database server's counters are accessible, and you should be able to connect via SQLcheck. If there is no return information, then there is an issue with the permission level of the account attempting to access the database server. |

| |
| What should I do if the SQLcheck dials do not show any information? |
A lack of statistics for the dials in SQL check usually occurs because the SQL counters that look for that information are unavailable.
You can check whether this is the case by running Perfmon:
- Go to start... run and execute "perfmon.exe"
- Right click or press ctrl-I in the counter window to bring up "Add counters"
- Connect to the computer where the SQL Server is installed under "select counters from computer:"
- Under Performance Monitor object, select any object prefaced with SQLServer: and add a counter to the list
If the counters are not available, they might not have been installed initially or they may have been disabled by a service pack.
This situation is easily resolved.
If the statistics have disappeared just after an upgrade to the monitored server's OS or SQL Server, you may need to restart that computer for the counters to become active again.
If the counters were never installed before, just use the SQL server setup CD to install the counters.
If the counters have been installed before, and a restart doesn't resolve the issue, please follow the instructions below. Please note that this procedure requires a stop and restart of SQL Server on the machine:
- Unload the SQL Server Counters. In command line, execute "unlodctr MSSQLServer"
- Verify that the file C:\Program Files\Microsoft SQL Server\MSSQL\BINN\sqlctr.ini is defined with all counters.
- From the command line, go to C:\Program Files\Microsoft SQL Server\MSSQL\BINN and execute "lodctr sqlctr.ini"
- In command line, execute "net stop mssqlserver", then execute "net start mssqlserver"
Further, SQLcheck will show no real-time database performance statistics if the server has been started with the parameter -x, which disables the keeping of statistics. To determine if this is the case, open Enterprise Manager, right click the server, go to Properties, and view Startup Parameters.

| |
| What should I do if I experience problems viewing SQLcheck in 16-bit color with Remote Desktop? |
When viewing the SQL Check GUI in remote desktop using a color-depth less than 16-bit, you may experience problems such as flickering, refresh stalling, or a GUI crash.
CAUSE:
There is a known issue with the redrawing method in the application at less then 16-bit color.
SOLUTION:
Please increase the resolution of your remote desktop connection to 16 bit color.
You can find this option under the Display tab -> Colors section.
