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 lookup names of systems contacting the server
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.

NDMPCONTROLPORT The internal communications port used for certain Network Data Management Protocol (NDMP) operations
NDMPENABLEKEEPALIVE The TCP keepalive mechanism

SHMPORT

AIX operating systemsHP-UX operating systemsLinux operating systemsOracle Solaris operating systemsThe TCP/IP port address of a server when using shared memory

Windows operating systemsThe port that the server listens on for shared memory connections
SNMPHEARTBEATINTERVAL The interval in minutes between queries of the Tivoli Storage Manager server
SNMPMESSAGECATEGORY The trap types used when messages are forwarded from the server
SNMPSUBAGENT The parameters needed for the Tivoli Storage Manager subagent to communicate with the SNMP daemon
SNMPSUBAGENTHOST The location of the Tivoli Storage Manager SNMP subagent
SNMPSUBAGENTPORT The port address of the Tivoli Storage Manager SNMP subagent
SSLDISABLELEGACYTLS Specifies whether to use protocols earlier than Transport Layer Security (TLS) 1.2 for Secure Sockets Layer (SSL) sessions between the server and the backup-archive client or storage agent
SSLFIPSMODE Specifies whether the Federal Information Processing Standards (FIPS) mode is in effect for Secure Sockets Layer (SSL)
SSLTCPADMINPORT The port address on which the server's TCP/IP communication driver waits for requests for SSL-enabled sessions for the command-line administrative client
SSLTCPPORT The SSL-only port number on which the server's TCP/IP communication driver waits for requests for SSL-enabled sessions from the following sources:
  • Command line backup-archive client
  • Backup-archive GUI
  • Administrative client
  • Application programming interface (API)
SSLTLS12 Controls Transport Layer Security (TLS) 1.2, an SSL protocol that is available for use with sessions between the server and the backup-archive client or storage agent
TCPADMINPORT The TCP/IP port number for administrative sessions
AIX operating systemsHP-UX operating systemsLinux operating systemsTCPBUFSIZE AIX operating systemsHP-UX operating systemsLinux operating systemsThe size of the buffer used for TCP/IP send requests
TCPPORT The TCP/IP port number for client sessions
TCPWINDOWSIZE The client node TCP/IP sliding window
