DFHSIJ1 executable module

DFHSIJ1 is the last to be executed in the process of system initialization. It issues the message ‘CONTROL IS BEING GIVEN TO CICS’ and passes control back to DFHAPSIP. DFHSIJ1:

• Links to DFHCRSP, if IRCSTRT=YES is specified as a system initialization parameter, to start up the interregion communication session
• Links to DFHPSIP to enable the system spooling interface
• Enables the DL/I high-level programming interface by acquiring an exit program block and addressing DFHEDP
• Enables AUTOINSTALL
• Links to the second-stage PLT programs listed in DFHPLT, then deletes this table
• Issues a DFHLDLDM SET_OPTIONS call to instruct the loader domain to write all outstanding program definitions to the catalogs.
