Setting Up Security for Local Connections to a Host

The SECURITY_LOCALCONNECTION configuration parameter enables a database server administrator (DBSA) to set up security checking for local connections with the same host. The table below shows the settings of the SECURITY_LOCALCONNECTION configuration parameter that you can use.

Table 17. SECURITY_LOCALCONNECTION Configuration Parameter Setting
Setting Explanation
0 No security checking occurs.
1 Dynamic Server compares the user ID of the owner trying to connect with the connection user ID. If these do not match, Dynamic Server rejects the connection.
2 Dynamic Server performs the same checking that is performed when SECURITY_LOCALCONNECTION is set to 1. In addition, Dynamic Server gets the peer port number from the network API and verifies that the connection is coming from the client program.

If you set SECURITY_LOCALCONNECTION to 2, you must have SOCTCP or IPCSTR network protocols.

If SECURITY_LOCALCONNECTION is set to 1 or 2, Dynamic Server establishes a connection only if the connection meets the requirements of the security check.
