Administration requirements

Note: Starting Informix JDBC Driver version 4.50.JC10, the use of LDAP to retrieve Informix server connectivity information from a stored SQLHost files inside of an LDAP server has been removed. Hence, SqlhUpload and SqlhDelete utilities are also not supported.

If you want the LDAP server to store sqlhosts information that a JDBC program can look up, the following requirements must be met:

The LDAP server must be installed on a computer that is accessible to the client. The LDAP administrator must create an IFXBASE entry in the LDAP server.
For more information about LDAP directory servers, see:
- www.oracle.com
- www.openldap.org
If you want to use the HCL Informix® SqlhUpload and SqlhDelete utilities, which can load or delete the sqlhosts entries from a flat ASCII file, the servicename field in the sqlhosts file must specify the database servers port number. For more information, see Utilities to update the LDAP server with sqlhosts data, next.
The LDAP administrator must make sure that anonymous search is allowed on the sqlhosts entry. For more information, see the LDAP server documentation.
