Description

The AP domain journal control gate service module handles WRITE_JOURNAL_DATA calls made by the user exit’s XPI. It gets a TCA if the task doesn’t currently have one, and also a JCA. If the task already has a JCA, this is stacked. It then copies the parameter list passed in the domain call, to the JCA, and then issues one of four journal writes, depending on the request. Finally the return code from the JC write is copied into the domain parameter list, and the JCA and TCA are released if they were obtained by DFHAPJC.
