Server communication options

You can use server options to specify server communication methods and their characteristics.

Table 1. Communication options
Option Description
ADMINCOMMTIMEOUT The amount of time that the server waits for an administrative client message during an operation that causes a database update
ADMINIDLETIMEOUT The amount of time an administrative client session can be idle
ADMINONCLIENTPORT The port that determines whether administrative sessions can use the port specified in the TCPPORT option
COMMMETHOD The server communication method
DBMTCPPORT The port number on which the TCP/IP communication driver for the database manager waits for client session requests
DNSLOOKUP Control of use of Domain Name Services to look up names of systems contacting the server
FIPSMODE Specifies whether the Federal Information Processing Standards (FIPS) mode is in effect for non-SSL operations.
LDAPCACHEDURATION Determines the amount of time that authentication sessions, to the same node or administrator, are skipped. You might see a slight performance boost when skipping sessions.
LDAPURL Specifies the LDAP directory server. Each setting must have the LDAP directory server name, a port number, and the base distinguished name of the namespace or suffix that the server maintains.
