說明

The TCPALVER subsystem parameter specifies the type of security credentials to accept for TCP/IP connection requests. It is recommended that you set the parameter to SERVER_ENCRYPT and require encrypted security credentials. With the required permissions to use the RACF passticket service, you can use RACF passticket to connect to Db2.
