Storage Commands

Storage commands may be submitted to display shared storage such as CSM or VTAM buffer pools. The Communications Storage Manager (CSM) is a component of VTAM that allows authorized host applications to share data with VTAM and other CSM users without having to physically copy the data. CSM shortages may impact response time. VTAM buffer pools are used by TCP/IP for applications such as CICS sockets, Telnet, FTP and others. The buffer pool types specifically used by TCP/IP include: IOBUF, LFBUF, CRPLBUF, TIBUF, and CRA4.
