These parameters apply only if you have licensed the VTS Agent. If you have not licensed the optional VTS product, do not change the defaults supplied for these parameters.
There are two parameters that you can specify: VTSFIRST and VTSLAST. The parameters VTSFIRST and VTSLAST control the sequence in which tableBASE searches libraries when VTS is installed.
VTSFIRST is the name of a VTS-TSR that is to be searched for tables before searching any libraries listed in the tableBASE library list (LIB-LIST). To override the installation default for VTSFIRST use the TBOPT DD statement.
VTSLAST is the name of a VTS-TSR that is to be searched for tables after searching any libraries listed in the tableBASE LIB-LIST.
- VTS users who run applications that employ tableBASE’s TBCALLV and TBASEV interfaces may also need to override their default SWITCHES. For more details, see VTS User access.
- The SWITCHES parameter does not apply to the VTS Interface product. For VTS, SWITCHES settings are inherited from the interface used for the applicable application.
- If the VTSFIRST or VTSLAST parameter is specified in TBOPT, in order for the VTS-TSR specified to be searched before or after the library list, the implicit open switch for application must be set to Y. The implicit open switch is the fourth switch of the SWITCHES parameter.
