User names can be a maximum of 30 characters. Uncheck Save user name and password if you prefer not to save your login information as part of the connection; doing this can help maintain the security of the database. However, if you do this, you will be prompted to provide a user name and password every time you connect.

Also note that Save user name and password must be checked for connection files that provide ArcGIS services with access to the database or geodatabase, or if you want to use the Catalog search to locate data accessed through this connection file.

In the following example, a connection is made to an Informix database with an ODBC data source name of ids12db using database authentication:.

You can move the connection to another location, just be sure users and applications that need to make a connection have read access to the directory where you place the connection file. If you use the data from this connection as the source for a service, such as a geoprocessing or geocoding service, you may need to place the connection file in a shared location on your network.

When you initially connect to a geodatabase in Informix , you connect to the Default version using the Database Connection dialog box. If you use geodatabase versioning and want to connect to a different transactional or historical version, change versions using the Geodatabase Connection Properties dialog box.

For more information, see Connect to a specific geodatabase version. You can use a data source name when registering the database—in which case you must create an ODBC data source before registering—or you can provide a string of connection information referred to as a DSNless connection. This is optional; if you do not have a data source name, you can connect to the Informix database using a string of connection information, which is referred to as a DSNless connection string.

To alleviate connection issues, remove the reference information from your user profile and re-reference your database client libraries using the following steps. If you did not configure an ODBC data source, comment out this line. If you want your web services to use the data in your Informix database or a geodatabase in Informix , you must create a service definition file , uncheck the option to Include data in service definition when publishing , and then publish the file to an ArcGIS Server site.
