File handling restrictions in the independent ASP QSYS.LIB file system

 

Here are the restrictions to be aware of when handling files in the independent ASP QSYS.LIB file system

• Logical files are not supported.

• Physical files supported for text mode access are program-described physical files containing a single field and source physical files containing a single text field. Physical files supported for binary mode access include externally-described physical files in addition to those files supported for text mode access.

• Byte-range locking is not supported. For more information about byte-range locking, see the fcntl()--Perform File Control Command topic.

• If any job has a database file member open, only one job is given write access to that file member at any time. Other requests are allowed only read access.
