Missed Connection: Troubleshooting More Database Errors

Let us take a look at some of the database errors that especially involve the Open Database Connectivity aka ODBC:

Error 1: Error: “Cannot Access Database (Error=40960)

This error is normally encountered when the Data Source Name-DSN is used for the database setup points to an incorrect server:

Here are the steps to fix this:

• Launch the Data Sources (ODBC) (on a 64 Bit operating system ensure the 32-bit Data Sources (ODBC) is used
• Now Select the correct DSN and click Configure
• Now Complete the configuration of the DSN using the right settings

Error 2: “Invalid User ID. The Connection User ID specified in the System Database Profile is not Valid.”

Here are the steps to resolve the error:

• Start the Verification if the System DSN used in ODBC is using the correct SQL login credentials.
•  In case the server name is used, the program creates a System DSN named [server name] 32.
• Now Select System DSN 
• Next, click Configure
• Now Enter SQL credentials and test the connection.
• Launch Database setup and assign verified DSN to Company and System databases.
• In case the error is user-specific connecting via a terminal server on Windows 2008, you need to right-click on the program and run it as an administrator.

There are times when you might encounter the same error when you are logging in to Sage 300 ERP Microsoft SQL database, where you can encounter invalid database specifications. The reason can be because of damage to the Microsoft SQL Native Client Driver. The problem can be resolved by either installing or repairing the SQL Native Client Driver. Likewise, the same error can also occur when the user is trying to open the Company database.

Error “You Cannot Open this Company Because another Task has Locked the Database”

This error usually occurs when the user is trying to run version 11 of a Pervasive database on a virtual server. To resolve the issue, you will need to recreate the ODBC connection to the Pervasive database

• Navigate to the Windows Start menu, 
• Now select Start > All Programs > Administrative Tools > ODBC Data Sources (ODBC).
• Next, Select the System DSN tab.
• Now you need to Identify and select the ODBC connection for the Sage 300 ERP databases
• Next, Click Configure and make a note of all the settings you need to recreate this ODBC connection.
• Now Click Remove to delete the ODBC connection.
• Next, Click Add and recreate the ODBC connection.
• Finally, Save changes.
  • The other forms of error that can commonly occur are when the user is trying to log in to the Sage 300 ERP and the database has been locked. To resolve the issue you will need to check on the SQL driver that has been installed on the faulty workstation and ensure that the right ones have been installed. Once done, you need to delete the existing ODBC DSN within the problematic workstation and create it once again. In case the DSN does not exist, create one and try logging in once again. 
  • There is yet another error; ‘Incorrect version of database software’. To start with, this error only affects those on Microsoft SQL Server 2005 onwards with Sage 300 ERP 5.6 and above. To solve this, start by removing any ODBC connections in the ODBC setup within the Windows referencing to that database server and setting up only the SQL Native Client.

Performance Issues on a Standalone or Network

Section 1: Sharing of Permissions & Security

• In case the shared data folder’s permissions and/or security have not been set properly, this can cause it to be slow. 
• Ensure that the network drive within each workstation has been mapped directly to the shared folder and not to a sub-folder (for instance, Sage 50 is shared, but the drive is mapped to the Company); if it is, disconnect and remap the drive

Section 2: Sage Company Size

• The size of a Sage company directly affects the performance of the program where large databases can result in longer load times for the program.
• To check a company’s size, Click select Help >Support Utilities > File Statistics.
• In the case of Large companies, they must be purged to remove old transactions/inactive records and decrease the company size.

Section 3: User Account Control (UAC)

• In Windows 8.1 or 10, UAC can lead to slowness by not accessing Sage to properly access the shared data files and/or program files.

Section 4: IPv6

• When using Windows 8.1, or 10, you need to disable IPv6 in order to significantly enhance Sage’s performance but can cause issues with Windows OS.
• Instead, you need to configure Windows OS to prefer IPv4 addresses over IPv6.
• Consult with your Local IT or Network Administrator for assistance with this.

Section 5: Anti-virus and Firewall Software

• You need to contact your IT professional or your security software manufacturer for instructions on configuring the exceptions list.

Section 6: Network Connection

• As you know Sage is not supported on wireless networks. 
• Using a wireless network can cause performance and/or data integrity issues.
• Hence It is strongly recommended to use a hard-wired connection within the program.
• Next, Verify if the server and workstation(s) are on the same domain or workgroup.
• Now Verify if the server can ping the workstation by name and receive a response from the correct IP address and that the workstation can ping the server by name
• Now Check the network speed. 
• The Network-related issues can be confirmed by changing one of the workstations to a local data path and opening a sample company. 
• In case the performance issues desist after bringing the data over to the local machine, then you need to contact an IT professional to troubleshoot across the network.
• Now Verify if there are no bad or faulty network cables or network cards in the environment.
• Be sure to replace any damaged equipment.
• In case the system experiences performance issues comprising dual network interfaces (active wireless and wired network connections) then you need to disable the unused interface.
• Consult with your IT professional to diagnose and repair network latency.

Section 7: Memory & Processor Speed

• Ensure each computer meets at least the minimum processor and RAM requirements for Sage.
• Within the server, you need to increase the amount of RAM in correspondence with the number of workstations that are accessing Sage; a good idea is to have 2GB of RAM per workstation.
• You might require more memory/processor speed if working in multiple companies at once.
• Next Check Sage’s performance on the server; in case the server is slow, every workstation will also be slow.
• Now Verify if the processor and memory resources have not been artificially limited. This can be done by pressing the Windows+R keys, type msconfig, and then click OK.
• Note: When prompted to allow the program to make changes, Click on Yes.
• Click the Boot tab.
• Select Advanced options.
• If either Number of processors or Maximum memory is selected, clear them.
• Click on OK.
• Click on OK again.
• Finally, Restart the computer.

Section 8: Hard Drive Space and Virtual Memory

• Every PC’s hard drive should have a minimum of 1 GB or three times the company database size, whichever is larger, of free space.
• Running Windows’ Disk Cleanup and Defragmenter utilities on each PC will also ensure free disk space.
• Every computer’s virtual memory should be set so it at least matches the amount of RAM on the system.
• In the case of RAM, the more virtual memory a computer has, the better it will run.

Section 9: Background Applications

• The slow performance can also be due to the Other programs and background applications running at the same time as Sage.
• In this case, you need to reboot all your systems into Selective Startup to verify if background programs are affecting Sage’s performance.
• In case the performance improves after doing so, you need to start re-enabling services and startup items one at a time until the one that is the main issue is discovered.

Section 10: Data Entry

• Start by Changing the Global Options
• Now click Select Options, and then Global.
• Next, Select the General tab.
• Go to Improve Performance and Check one or more options within,

• If using Windows 8, Microsoft .NET 4.5 is built into the operating system, so instead of reinstalling it, disable it, reboot, and then re-enable it.

Section 13: The User Does not have the Correct Access

• Each user in the network needs either Administrator or Power User access

Section 14: Oversized Form (.FRM) File(s)

• Start by Checking the Forms and individual company directories, 
• Next sort the files in the directory by size.
• Any large forms can be moved out of the Forms and individual company directories.
