IMS support includes two new transactions, /CIC and /IMS, that you use to switch enterprise servers to CICS and IMS modes respectively. In order for these new transactions to be available you need to update your resource definition file using the caspcupg command.
To update your resource definition file, enter the following command:
caspcupg /dp=resourcedefinitionpath /o
where resourcedefinitionpath is the path to the system resource defintion file to be updated. If you are using the default system resource defintion file, dfhdrdat located by default in %ProgramFiles(x86)%\Micro Focus\Studio Enterprise Edition x.x\files\sys , you can omit /dp=resourcedefinitionpath. See caspcupg for more information on the caspcupg utility.
Updating a resource definition file with the /CIC and /IMS transactions in this way is a one-off process. Once you have used caspcupg to upgrade a resource definition file, any enterprise server that uses the updated resource definition file can use the new transactions.
