The SHOW UDB command can be used to display details about files available to the system. This information includes details about the number of active users, space usage, and the status. In addition, any open error codes that caused a file to be disabled are displayed.
The SHOW VSAM command can be used to obtain additional details about the system's VSAM files. These include record and Control Interval sizes, statistics on the number of CI and CA splits and details of any buffer or string shortages that have been experienced. In OS/VS systems, this display also provides details on the performance of the Local Shared Resource (LSR) pool if one is in use.
Note: For more information about the SHOW UDB and SHOW VSAM commands and their use, see the online help.
