M204.0611 All file DCB's are in use
You are attempting to open a Model 204 file and have run out of DCBs. Each data set of a Model 204 file requires at least one file DCB area when the file is open. If the file spans data sets, one DCB is required per data set for the file. When the last user to have the file concurrently open closes it, all its DCB areas are freed and can be used for opening other files. When running Model 204 under z/VSE, a DCB is equivalent to a DTF. The total number of file DCB areas is controlled by the parameter NDCBS.
Response: An Online user may wait and try to open a file later. Notify your system manager about changing the NDCBS parameter.
System manager response: Increase the NDCBS parameter. NDCBS defaults to a value of 10, and it can be set on the User 0 parameter line.
