Use the CHGQRYA command with the QRYOPTLIB (query options library) parameter to specify which library currently contains or will contain the query options file QAQQINI. The query options file will be retrieved from the library specified on the QRYOPTLIB parameter for each query and remains in effect for the duration of the job or user session, or until the QRYOPTLIB parameter is changed by the CHGQRYA command.
If no library is specified for this parameter, then the library QUSRSYS is searched for the existence of the QAQQINI file. If a query options file is not found for a query, no attributes will be modified. The initial value of the QRYOPTLIB parameter for a job is QUSRSYS.
