Click the Security tab. Click the Sites… button next to Trusted Sites).
c. See the following link for more detailed Client settings.

iServerManager Workstation

a. Windows 2000 (Service Pack 4 or higher) or WindowsXP/Windows 2003

Before the upgrade

If you are doing a system replacement please get all users off the current LIMS application and reset iis before proceeding. (From the web server hit Start/Run/iisreset). Make sure you backup the web files and folders and the database of your existing system before proceeding with the system replacement.

IServer Install

All programs/files are contained in the .zip file you were provided. Unzip to a folder and follow instructions contained therein. To set up iServer properly you must be logged into the web server as an administrator. If you have previously installed iServer, please run the uninstall exe from the Start/All Programs/LABLynx iServer/Uninstall menu item. Then run the latest version of the iServer setup on your Web server.


Open the file. Extract it to a folder on your web server and run the setup exe included. This will install iServerManager which will be used later in the process. In most cases if errors occur during the install process, it is due to the fact that certain dll files may be in use while the install tries to replace them. It is ok to ignore these errors.

Making the install

Web site Creation:

1. Copy the Web folder included in the install package to the web server.

2. If you are doing a new install copy the contents of the Web folder (The LIMS folder) where you would like your web folder to reside. (usually c:\inetpub\wwwroot\). Then skip to step three. If you are doing a system replacement you can simply copy this directory over your existing LIMS directory on the web server. If the name of your web folder is not LIMS, rename the LIMS folder that was included in the replacement package to your actual Web folder name and proceed with coping over your existing folder. You can now skip to step four to validate your IIS settings.

3. Using Internet Services Manager, create a new virtual directory on your Web site. (Accept the defaults when setting it up.) Point the virtual directory to the new Web location (e.g. c:\inetpub\wwwroot\lims).

a. Right click on the default Web site under IIS Console and choose New/Virtual Directory.
b. Hit the Next button.
c. Alias your website as "LIMS" and hit Next.
d. Browse to where you copied the Web folder contents above at step two and hit Next. (Usually c:\inetpub\wwwroot\)
e. Select all the options for virtual directory access permissions except Execute. Leave Execute unchecked and hit Next.
f. Click Finish.

4. Special instructions:

Special Instructions for Windows 2003

a. In IIS, click the nodes on the left and navigate to the Web site.
b. Right click on the Web site and choose the Properties option.
c. On the Virtual Directory tab click the Configuration button.
d. Click the the Options tab.
e. Check the option "Enable Parent Paths for the Web application". Then click OK twice.
f. In IIS, select the Local Computer node. Right click, click properties, click the MIME Types ... button and enter this new MIME type:
            File Extension: .*
            MIME Type: application/octet-stream
(This is especially necessary for the .vs file extension. The LABLynx application will not function correctly if the .vs file extension is not included in the MIME types. If your security settings prevent you from adding the .* MIME type you must at a minimum add the .vs file exteinsion to the MIME types)
g. Right click on the Web Server Extension node in IIS and hit the Properties option.
h. Make sure that "Active Server Pages" and "Server Side Includes" are both allowed on the Web server. Highlight the extension and hit the Allow button to activate. If "Active Server Pages" are not allowed the application will return a "404 Page Cannot be Found" error.

Special Instructions for Setting up Oracle 9i for ASP

a. Reboot the server at least once after installing either IIS or Oracle.
b. Add the following entries to sqlnet.ora (typically c:\oracle\ora92\network\admin\sqlnet.ora) and save:
            SQLNET.AUTHENTICATION = (none)
c. Give the Internet guest user account (IUSR_MachineName), IWAM_MachineName, the Authenticated User account and if using iis 6.0 or higher the IIS_WPG User account full security rights to the Oracle Home folder (typically c:\oracle). Also, be sure to check the Reset Permissions on all child folders.
d. Reboot the machine. (Refer to Microsoft knowledge base article for more information:;EN-US;Q255084)
5. Create a new printer. (Note, this is used by the reporting engine to format reports. It does not have to be an actual physical printer, just a setup of a printer so the reporting engine can use the drivers.) You might have one setup and can use it, but if it does not work, follow these steps:
a. Go to Start/Settings/Printers.
b. Click Add Printer.
c. Click Next, select Local Printer and uncheck "Automatically detect and install my plug and play printer."
d. Click Next, select "Use the following port," and then select File: for the port.
e. Click Next, select HP for the manufacturer and HP LaserJet 8000 Series PCL for the printer.
f. Use the default settings, but you do not have to print a test page.
g. Right click the new printer, which should be named "HP LaserJet 8000 Series PCL." Be sure to name it or update the default setting for the printer name. Make sure everyone has access to this printer. Important note: share the printer as the same name (HP LaserJet 8000 Series PCL). If you are using a different printer, make sure to share it as the same name.

6. Once the database has been created you will need to link your Web application to the database. Instructions are below.

Set File Folder Permissions:

We now need to set permissions on two folders on the Web server. Depending upon your security procedures you will need to make sure the Internet Guest User account (IUSR) and or the Authenticated User accounts are in the list of eligible users and have Full Control (or at least read, write, modify, read & execute and list folder contents) to the folders listed below and their children. If you are using IIS 6.0 or higher you will need to do the same for the IIS_WPG User account. To change permissions on child folders and files right click on the parent folder. Hit the advanced button on the security tab. Choose the "reset permissions on all child objects and enable propagation of inheritable permissions" option, then hit ok.

C:\iServer (Or the alternate location you chose of your iServer folder)
C:\inetpub\wwwroot\LIMS (Or the alternate location you chose of your web folder)

Database Creation:

The install package will include a database directory. In that directory you will find the database backup that can be restored. Copy the database directory included in the install package to your database server. **Note: Database names and passwords cannot contain any of the following special characters: "?" , "#", "&".

For SQL Server
Note that if the Web application user is not in the db_owner role, the application user will need to be in the db_dataread, db_datawrite roles and granted execute permissions on all non-system stored procedures and user-defined functions. Your dba will need to make sure these permissions are granted.
  1. Navigate to the list of databases.
  2. Find the LIMS database in the list and right click on it.

1. You will need to create a new (or replace an existing) SQL Server Database.
2. From the Database Server select Start / All Programs / Microsoft SQL Server / Enterprise Managers.
3. Click and open the nodes on the left until you have navigated to the list of databases. (Note that if you are doing a database replacement instead of a clean install skip to step nine.)
4. Right click on any database in the list and select New Database.
5. Use "LIMS" for the name of your new database.
6. If you would like to modify where the actual data files reside you can modify the datafile locations under the Datafile and Transaction Log tabs
7. Click Ok to create the database.
8. Now find your new (or previously installed) database in the list and right click on it.
9. Choose All Tasks and click Restore Database.
10. Choose the From Device radio button.
11. Hit the Select Devices button.
12. Hit the Add button.
13. Hit the ... button and browse for the backup file included in the replacement package.
14. Hit OK three times
15. Select the Options tab.
16. Check Force Restore Over Existing Database. (Make sure the Restore As file names and paths match the data files created with the new database. e.g. If your database is named LIMS, your data files under the Move to Physical File name column should be LIMS_Data.mdf and LIMS_Log.ldf. You do not need to modify the Logical File name column.)
17. Click OK. It should now restore the new database over the existing one.
For Oracle
Note that the restore of the backup file must be performed from a Windows machine (preferably the Web server). We have experienced character interpretation issues when restores have been performed from UNIX machines. LabLynx also requires the use of the WE8MSWIN1252 character set. Failure to use this character set could cause the system to fail in certain areas.
If you are doing a new install you will need to create the lablynxuser schema in your database. See the Example script below. If you are doing a system replacement place, you will need to drop the existing user first before creating it. From the database server login to SQLPlus as sys. Here is a sample script to help create the schema:
            drop User lablynxuser Cascade;   --Only used on system replacements
            create user lablynxuser
            identified by lablynxuser
            default tablespace T_LABLYNX
            temporary tablespace T_LABLYNX_TEMP
            quota unlimited on T_LABLYNX;
            GRANT CONNECT, RESOURCE TO lablynxuser;
Once the above script has been run and the lablynxuser has been created you can restore the backup over it.
Included in the database directory along with the backup file of the database is a LIMS_RESTORE_DB.bat file. This file is used to do the db restore and will need to be modified. To edit the LIMS_RESTORE_DB.bat file right click on it and select edit. (Notepad is fine.) You should...
  • Replace the ??? with the system password. (set UserPass=system/???)
  • Replace the ??? with the TNS name. (set TNSNAME=???)
  • Replace the ??? with the Location of the backup file. (set DMPLocation=C:\???\)
  • In most cases the from user and to user can stay the same (lablynxuser). If lablynxuser is not the name of your schema then please change the to user name setting. (set TO_USER=???)
After you have finished editing the LIMS_RESTORE_DB.bat file save it. You can now double click the file to restore the database.

Set LIMS connection to the database

  1. From the Web server open the iServerManager.exe.
  2. From the menu choose File / Open.
  3. Browse for the setting.isv file stored under the LIMS Web directory. Select it and hit Open. (If no setting.isv file is available, skip to step eight.)
  4. You will need to modify the server entry. (This is the database server name for SQL server systems and the TNS name for Oracle systems.)
  5. You will also need to modify the database name, user, and password entries to match your settings.
  6. You will also need to set the Current App value to a value provided by LabLynx. See your readme file for this value.
  7. Once those settings have been changed you should hit the Save Encrypted button.
  8. If the setting.isv file is not available the global.asa file can be edited manually. To do this open the global.asa file in Notepad. Scroll down the file until you see the following text:
            '*************** Setup of Database Connection *************
            strDatabase = "????" 'Name of database
            strServer = "????" 'Blank string if database is on the webserver, IF NOT IP address of database server
            strUser = "????" 'Database user
            strPwd = "????"  'Database user password
Replace the ???? with the applicable values:
  • strDatabase = This is the name of the database. It is not used in Oracle systems.
  • strServer = This is the name or IP of the server for SQL Server systems. It is the TNS name for oracle systems.
  • strUser = This is usually sa for SQL Server systems and lablynuser for Oracle systems.
  • strPwd = This is the database password.
Afterwards, save the global.asa file.
9. Reset iis. (From the Web server hit Start/Run/iisreset.)

Additional Instructions

If you are currently using the Active Reports functionality and are installing the application for the first time or moving the application to a new directory, it will be necessary to modify the template location of all the active reports saved in the application. If a script was provided to do this operation, you can run it now. If no script was provided, you can log into the application and do this manually (the login information is below under the install complete heading). In the application under the LabLynx Menu go to System / Reporting Tools / Reports Management. Click on each report that has a Report Type of Active. For each report resave the record and it will automatically update the report template location to match the new directory. You will need to trigger the save button by modifying the record.

If any additional scripts or directions were included you can proceed with them now.

The system should now be functional. You can login to the application with the sysadmin / lablynx user password combination.
