GLOBAL Control Statement

The GLOBAL control statement is coded as follows:

GLOBAL    TCPNAME=tcpipname,
  [MAXTASK=nn,],
  [PREFIX=prefixname,]
  [UNIT=unitname,]
  [VOL=volser,]
  [MSGLEVEL=nn,]
  [STORCLAS=storageclassname,]
  [DATACLAS=dataclassname,]
  [MGMTCLAS=managementclassname,]
  [TRACE/NOTRACE]

TCPNAME=

A required parameter that specifies the name of the TCPIP address space on the mainframe where CTS is running.

MAXTASK=

An optional parameter from 1 to 10 that specifies the maximum number of concurrent data retrieval operations that can be active at any one time. This specification is used to stifle resource use when multiple servers require data retrieval at the same time. All data retrieval sessions are queued up and serviced by the available data retrieval subtasks.

Default: 3

PREFIX=

An optional parameter that will form the name of the Distributed Tape Inventory File. The SRVDEF name is appended to this operand to form the fully qualified data set name.

Default: CAI.ISPON

UNIT=

An optional parameter that specifies a valid unit name that is used to dynamically allocate the distributed tape inventory file.

VOL=

An optional parameter that specifies the volume serial number to use when allocating the distributed tape inventory file.

MSGLEVEL=

An optional parameter that specifies the level of messaging that will occur. Valid values are 0 through 9. The default is 0 which lists only the most important messages. This can be changed with a console command during execution. Setting this to 9 provides supplementary information that can be used to diagnose abnormalities.

Default: 0

STORCLAS=

An optional parameter that specifies a valid SMS storage class to be used when allocating the distributed tape inventory file.

DATACLAS=

An optional parameter that specifies a valid SMS data class to be used when allocating the distributed tape inventory file.

MGMTCLAS=

An optional parameter that specifies a valid SMS management class to be used when allocating the distributed tape inventory file.

TRACE/NOTRACE

An optional parameter that displays all iSponsors found on a remote backup server when DTS connects to it.

Default: NOTRACE
