Start options

Start options are listed in this section alphabetically; however, you can code them in any order.

Precede the option list with three commas and enclose the group of options in parentheses.

Start options that are entered on the START command must be separated by commas. Do not leave any blanks between options.

For more information on the START command, see z/OS Communications Server: SNA Operation.

Notes:
  • 1 APPNCOS is meaningful only if the NODETYPE start option is also used.
  • 2 BN is meaningful only if the NODETYPE=NN start option is also used.
  • 3 BNDYN is meaningful only if the BN=YES start option is also used.
  • 4 BNORD is meaningful only if the BN=YES start option is also used.
  • 5 CDSERVR is meaningful only if the NODETYPE=NN start option is also used.
  • 6 CDSREFER is meaningful only if the NODETYPE=NN and CDSERVR=NO start options are also used.
  • 7 The CMPMIPS start option is meaningful only if the value for CMPVTAM is greater than 1.
  • 8 CONNTYPE is meaningful only if the NODETYPE start option is also used.
  • 9 CPCP is meaningful only if the NODETYPE start option is also used.
  • 10 Specify the CSDUMP start option twice to set both message and sense code triggers.
  • 11 DIRSIZE is meaningful only if the NODETYPE=NN start option is also used.
  • 12 DIRTIME is meaningful only if the NODETYPE=NN start option is also used.
  • 13 DLURSAW is meaningful only if the NODETYPE=NN start option is also used.
  • 14 Because of the volume of messages that can be generated, it is not recommended that this option be enabled during normal operation. Instead, it is recommended that this option be enabled (using the MODIFY VTAMOPTS command) on all necessary hosts only when trying to diagnose specific problems. After the problem has been diagnosed or documentation has been collected, this option should be disabled once again (using the MODIFY VTAMOPTS command).
  • 15 If the DSPLYMAX start option value is less than 100, that value is the default for DSPLYDEF.
  • 16 Use the CFSIZER tool to determine the appropriate number of lists for your EZBDVIPA structure, as well as, the suggested INITSIZE and SIZE values for the structure. Before you modify the DVLSTCNT option to increase the number of lists requested for the EZBDVIPA structure, update your CFRM policy with the recommended INITSIZE and SIZE values. Increasing the number of lists requires more storage for the EZBDVIPA structure. Make sure the same DVLSTCNT value is configured in all VTAMs in the sysplex. To enable the modified DVLSTCNT value, issue the following SETXCF MVS™ command to rebuild the EZBDVIPA structure: SETXCF START,REBUILD,STRNAME=EZBDVIPA. See SETXCF command in z/OS MVS System Commands for more information.
  • 17 DYNADJCP is meaningful only if the NODETYPE start option is also used.
  • 18 Two character prefix.
  • 19 EEHPRANR is meaningful only when the NODETYPE=NN start option is also used.
  • 20 The EEVERIFY start option is meaningful only if VTAM® provides RTP-level HPR support. The NODETYPE start option must be coded and the RTP value must be specified on the HPR start option.
  • 21 ENCRYPTN=CCA needs to be coded when Triple Des Encryption is required.
  • 22 The ENSEMBLE setting is used to either permit or deny connectivity to the intraensemble data network and the intranode management network. It does this by either allowing or denying activation of OSX and OSM interfaces.
  • 23 HOSTNAME is meaningful only if the NODETYPE start option is also used. If neither HOSTNAME nor IPADDR is specified on any of the GROUP definition statements within the Enterprise Extender XCA major node, then either the HOSTNAME, TCPNAME, or IPADDR start options must be specified in order to activate an Enterprise Extender link. The HOSTNAME start option specifies the default hostname to be used for name-to-address resolution as part of activating an Enterprise Extender connection, and must resolve at this node to a static VIPA address associated with a TCP/IP stack at this node. If IPADDR is specified along with HOSTNAME on the START command, the IPADDR value is ignored.
  • 24 HOSTSA specifies the subarea number of this VTAM. If HOSTSA is not coded, then a default subarea number of 1 is used.
  • 25 HPR is meaningful only if NODETYPE is also used.
  • 26 HPRCLKRT=ADAPTIVE is meaningful only in Enterprise Extender configurations that have a defined capacity of 1 Gb (gigabit) or higher access speeds.
  • 27 This option is meaningful only if VTAM provides RTP-level HPR support.
  • 28 HPRSESLM=DISABLED is meaningful only on interchange nodes.
  • 29 INITDB is meaningful only if the NODETYPE=NN start option is also used.
  • 30 When specifying an InOpCode for the second parameter, always specify three digits by including any leading zeros.
  • 31 If an InOpCode is specified for the second parameter, the first parameter cannot be ALL.
  • 32 INOPCODE has no effect unless INOPDUMP is active for the resource when an inoperative condition is detected. See the MODIFY INOPCODE command in z/OS Communications Server: SNA Operation for more details.
  • 33 Multiple INOPCODE parameters can be specified by the START command, and will be processed left to right as they are entered. This is different from specifying the INOPCODE parameter on either the MODIFY INOPCODE command or the MODIFY VTAMOPTS command, where only one INOPCODE parameter is allowed for each entry of these commands.
  • 34 INOPDUMP status is propagated to resources that are defined within a TRLE when the entry is activated.
  • 35 IPADDR is meaningful only if the NODETYPE start option is also used. If neither IPADDR nor HOSTNAME is specified on any of the GROUP definition statements within the Enterprise Extender XCA major node, then either the HOSTNAME, TCPNAME, or IPADDR start option must be specified in order to activate an Enterprise Extender link. The IPADDR start option specifies the default IPv4 or IPv6 static VIPA address to be used when activating an Enterprise Extender connection. If HOSTNAME is specified along with IPADDR on the START command, the IPADDR value is ignored.
