Info

SHAREdmemUse the shared memory communication method when the client and server arerunning on the same system. This provides better performance than theTCP/IP protocol. This communication method is valid for AIX, HP-UX, Linux,and Solaris clients only.When specifying this communication method on AIX, the client can be loggedin as root or non-root, as long as the server is running as root. If the server isnot running as root, the user ID running the client must match the user IDrunning the server.Important: When using COMMMethod SHAREdmem on Linux, you mightreceive error message: ANR8294W Shared Memory Session unable to initializeon the server or storage agent console. By default, Linux is not set up withsufficient system resources to create the message queues. You must increase thekernel parameter, MSGMNI, to 128 (the default is 16). You can modify thisparameter by performing the following command:echo 128 > /proc/sys/kernel/msgmniTo enable this parameter to remain persistent after rebooting the system, youcan instead add the following line to the file /etc/sysctl.conf, then reboot thesystem:kernel.msgmni=128To view the current ipc settings, run this command:ipcs -lNow look at the max queues system wide value. The default is 16.ExamplesCommrestartdurationOptions file:commmethod tcpipUse only TCP/IP Version 4commmethod V6TcpipUse both TCP/IP Version 4 and Version 6, depending on how the system isconfigured, and the results of a domain name service lookup.Note: The dsmc schedule command cannot be used when bothSCHEDMODe PRompt and COMMMethod V6Tcpip are specified.Command line:-commm=tcpip-commm=V6TcpipThis option is valid only on the initial command line. It is not valid in interactivemode.The commrestartduration option specifies the maximum number of minutes youwant the client to try to reconnect to a Tivoli Storage Manager server after acommunication error occurs.You must be an authorized user to use the commrestartduration option.280 IBM Tivoli Storage Manager for UNIX and Linux Backup-Archive Clients Version 6.1: Installation and User’s Guide
Note: A scheduled event will continue if the client reconnects with the serverbefore the commrestartduration value elapses, even if the event’s startup windowhas elapsed.You can use the commrestartduration option and the commrestartinterval in busyor unstable network environments to decrease connection failures.Supported ClientsThis option is valid for all clients.Options FilePlace this option in the dsm.sys file. You can set this option on theCommunication tab, Common Options section of the Preferences editor.Syntax►► COMMRESTARTDuration minutes ►◄ParametersminutesThe maximum number of minutes you want the client to attempt to reconnectwith a server after a communication failure occurs. The range of values is zerothrough 9999; the default is 60.ExamplesCommrestartintervalOptions file:commrestartduration 90Command line:Does not apply.The commrestartinterval option specifies the number of seconds you want theclient to wait between attempts to reconnect to a Tivoli Storage Manager serverafter a communication error occurs.You must be an authorized user to use the commrestartinterval option.Note: Use this option only when commrestartduration is a value greater than zero.You can use the commrestartduration option and the commrestartinterval in busyor unstable network environments to decrease connection failures.Supported ClientsThis option is valid for all clients.Options FilePlace this option in the dsm.sys file.
