TSOLIB Command2 1 to 15 data sets for libraries.TSOLIB command operandsACTIVATE | ACTindicates that you want to include the specified libraries ahead of the standardsearch order.DEACTIVATE | DEACT | DEAindicates that you want to exclude the previously activated libraries from the topof the search order.If previous activation requests have been done unconditionally, DEACTIVATEcauses the last stacked request to become active again. See “Stacking loadmodule and program object library requests” on page 360 for more informationabout stacking library activation requests.DATASET(dsname[,dsname, ... ]) | DSNAME(dsname[,dsname, ... ])specifies the data set name of a load module library, or a list of data set namesof load module libraries, to be activated. Up to 15 data set names can bespecified.The data sets must be cataloged partitioned data sets, and they must be of thesame record format (RECFM = U).For the load module or program object libraries to be activated, the systemautomatically creates a ddname of SYSnnnnn. The ddname remains allocateduntil you issue TSOLIB DEACTIVATE or TSOLIB RESET.If you want to activate more than 15 data set names, use the FILE operand ofTSOLIB.For authorized commands and programs to be invoked from a library read“Further considerations” on page 359.FILE(ddname) | DDNAME(ddname) | LIBRARY(ddname)specifies a ddname that represents a load module library or a list of loadmodule libraries. The ddname must be allocated before you issue the TSOLIBcommand. The ddname remains allocated even after a TSOLIB DEACTIVATEor RESET command is issued. Use the FREE command to deallocate theddname when required.For authorized commands and programs to be invoked from a library read“Further considerations” on page 359.Using a ddname, compared to a dsname or a list of dsnames, allows for agreater number of libraries to be activated. Use the ALLOCATE command toassociate up to 255 data sets with a ddname; then issue TSOLIB ACTIVATEFILE(ddname).UNCOND | CONDcontrols the way TSOLIB is to treat an ACTIVATE request if previous requestshave been performed.UNCOND(the default) indicates that the activation request is to be doneunconditionally. Any active request is temporarily deactivated and stackedfor later re-activation. See “Stacking load module and program object libraryrequests” on page 360 for more information about stacking library activationrequests, and “TSOLIB command examples” on page 363.Note that stacked ddnames remain allocated.
