You use the TSO procedure FJGEN from the library OPENFT.CLIST to set up a new openFT instance or, subsequently, to modify the parameter settings of existing instances. In your openFT system, instances are identified via their instance names which you specify in INSTANCE NAME during FJGEN processing. FJGEN expects the load modules of openFT to be specified in the libraries OPENFT.LOAD and OPENFT.NCLOAD.
FJGEN runs a dialog to query the parameters to be defined during the first installation step. In particular, the qualifier under which the openFT administrative files and the instancespecific FT procedure library are stored is defined here. (OPENFT QUALIFIER).
The FJGEN command is required even if the installation parameters have been set using a file (see section “Setting up the FT parameter library”). If openFT is to run as a started task, the FT administrator must create the start procedure himself and specify the corresponding values for the installation parameters (see section “openFT as a job or started task”). Here also, however, the FJGEN command is required to create further command procedures and create instance-specific files.
The FJGEN command can also be used to change the installation parameters of an openFT instance. The named procedures are then regenerated in the instance-specific procedure library. The changes become effective the next time the installation-specific batch job is started with FJINIT from the <openFT qualifier>.<inst>.CLIST library.
If openFT is running as a started task, the FT administrator is responsible for making the corresponding changes in the start procedure, see section “openFT as a job or started task”.
When an instance-specific procedure library is concatenated, you can obtain information about the current values of the installation parameters using the FJGENPAR command from the <openFT qualifier>.<inst>.CLIST library.
A detailed description of the FJGEN command and examples are given in section “FJGEN- Set installation parameters”.
