information about shunted URs and URs that are restarting. The provided information<br />

includes age and status <strong>of</strong> the UR, the jobname with which this UR is associated, and the<br />

current step within the job.<br />

► To display entries currently contained in the shunt log:<br />

DISPLAY SMS,SHUNTED,{SPHERE(sphere)|<br />

URID(urid|ALL)}<br />

Entries are moved to the shunt log when DFSMStvs is unable to finish processing a sync<br />

point for them. There are several reasons this might occur; an I/O error is one <strong>of</strong> the<br />

possible causes. Depending on what was specified, you get information for a particular<br />

VSAM sphere, a particular UR, or for all shunted URs in the sysplex.<br />

► To display information about logstreams that DFSMStvs is currently using:<br />

DISPLAY SMS,LOG(logstream|ALL)<br />

If ALL is specified, information about all log streams in use is provided from the system on<br />

which the command is issued. The output includes the status and type <strong>of</strong> the log stream,<br />

the job name and URID <strong>of</strong> the oldest unit <strong>of</strong> recovery using the log, and also a list <strong>of</strong> all<br />

DFSMStvs instances that are using the log.<br />

► To display information about a particular data set:<br />

DISPLAY SMS,DSNAME(dsn)<br />

Use this command to display jobs currently accessing the data set using DFSMStvs<br />

access on the systems within the sysplex.<br />

IDCAMS command SHCDS<br />

The IDCAMS command SHCDS was enhanced to display and modify recovery information<br />

related to DFSMStvs. For more information about this command, see z/<strong>OS</strong> DFSMS Access<br />

Method Services for Catalogs, SC26-7394.<br />

Important: This chapter simply provides an overview <strong>of</strong> new operator commands to know<br />

to work with DFSMStvs. Before using these commands (other than the DISPLAY<br />

command), read the <strong>of</strong>ficial z/<strong>OS</strong> manuals carefully.<br />
