Fields

Field	Descriptions
Product	Always B97
Dataset Name	VSAM dataset name If a static system symbol has been replaced in the dataset name, both are displayed; the actual dataset name that is used (system variables have been replaced) and the dataset name that is stored in the database definition file (system variables have not been replaced).
Short Name	Short name of the VSAM dataset
File ID	File ID
CIsize	Specifies the size of the control interval (CI)
High Alloc RBA/ High Used RBA	Number of highest allocated relative byte address and of highest relative byte address in use
Cache Buffer	Number of 4K blocks used for caching
Type	The following values may be displayed: NO Database definition file DA Data file KE Key file SP Spool file of type spool IX Spool file of type index CA Spool file of type cache GL Spool file of type global index LO Log file SY Sync file
Dataset Status	The following values may be displayed: USE Dataset is in use CLS (Closed) Dataset could not be opened MOD (Model) Spool file in status model ONL (Read only) Dataset is read-only FMT (Format) Spool file is being formatted EMP (Empty) Dataset is empty ERR (Error) Dataset is in error FEX Format extend error FUL (Full) Dataset is full OPN (Open) Dataset is open
High Water Mark	High water mark (in percent)
I/O-Read	Database read access count
I/O-Write	Database write access count
I/O-Req.	Total number of database requests (I/O-Read, I/O-Write, and Caching)
Caching	Percentage the database was not accessed directly but via Speed Master
Warning threshold/ Allocated	These two fields are displayed only if the optional MAXSIZE value has been defined for this database in the database definition file: Warning threshold is a user-defined value (in cylinders) which can be used to monitor the growth of dynamic databases when extends are formatted (messages IRM9549I and IRM9549W). Allocated displays the amount of allocated space (in percent) in relation to the warning threshold.

The following information is displayed when you scroll down (PF8):

Field	Descriptions
VSAM Information fields	The name of the VSAM catalog, the name of the VSAM cluster, and the name of the VSAM cluster with the type DATA.
Space Information fields	The primary and secondary space requests in cylinders, the maximum length of data set records, the number of records per track, the totally allocated space in cylinders, the number of tracks per cylinder, and the number of extents in use are displayed.
SMS Information fields	SMS information on SMS management classes (MGMTCLAS), SMS storage classes (STORCLAS), and SMS data classes (DATACLAS) is displayed.
Volume Information fields	The number of defined volumes, the number of unused volumes (candidates), and the volser number (1 - 10) of the volume on which the data set is located are displayed.
