Processing the Modifications

During notify exit processing, you may either release its ownership of a resource or change its corresponding state, user data, or record data. Once the changes have been made in the NEPL, you issue IXLSYNCH to notify the system.

The effects of issuing IXLSYNCH for a modification to record data are as follows:

Update the record data associated with a resource
When IXLSYNCH is issued and the NEPLORTWRITE flag is set to ON (write record data), XES performs the following update:
- If a record data element is currently associated with the resource, then its contents will be updated.
- if there is not a record data element currently associated with the resource, then XES attempts to write to an available record data entry. If an available record data entry cannot be found, XES rejects the request and provides error return and reason codes to the requestor.
Delete the record data associated with a resource
When IXLSYNCH is issued and the NEPLORTDELETE flag is set to ON (delete record data), XES attempts to delete the record data element currently associated with the resource. If a record data element does not exist for the resource, XES ignores the request.
