Check that you are now ready to run the installation jobs:
If your existing CSIs do not have a control interval size of 4096 bytes, you must edit the DFHINST3 job (before running it) to change the CONTROLINTERVALSIZE(4096) parameter on the commands used to create the VSAM data sets for the new CSIs, to specify the same control interval size as the existing CSIs.
For further information about considerations for allocating CSI data sets, see the System Modification Program Extended: Reference manual, SA22-7772.
