Selection options z/OS DFSMShsm Diagnosis GC52-1387-00 |

The various selection options listed here are useful for narrowing and defining your trace data search. These options are used within examples later in this section. The START(yyddd[,hhmmss]) option allows you to select records for output starting from the specified date until the end of the data, or until an end date is reached, as specified by the END option. A start time can also be specified and is separated from the date by a comma. If you do not specify the START option, the system selects records that begin at the start of the ARCPDOX or ARCPDOY data set. If a start time is not specified, the default is 000000. The END(yyddd[,hhmmss]) option selects records until the date, and optionally time, are reached. A comma separates the date and time. The end date must be the same as, or after, the start date. If the start and end dates are the same, the end time must be the same as, or after, the start time. If you do not specify the END option, the system selects records through the end of the file. If an end time is not specified, the default is 235959. With both START and END options:
The TCB(aaaaaa[,bbbbbb,cccccc,....]) option selects records that match any of the TCB addresses you select. Up to 10 TCB addresses may be specified in this option. The TCB addresses are identified under the AS/TCB column in the trace output display. Each address must contain six characters, and each address must
be separated by a comma. Actually, only bytes two and three of the
actual TCB address are used in the trace address field, and these
are placed in byte positions one and two. Byte zero of the TCB trace
entry is used for address space identification. For activity that
is recorded in the ABARS secondary address space, use the last two
digits (in hex) of the ABARS address space identifier (ASID). The
following example helps illustrate this:
The MODULE(aaaaa[,bbbbb,ccccc.....]) option
selects all trace records that have been requested by the module you
specify. For example, if you specify MODULE(CTL), all the trace records
requested by ARCCTL are selected. You may specify up to ten module
names for this option. Each name can contain up to five characters,
with each name separated by a comma. Whenever you specify a module
name of less than five characters, DFSMShsm pads the name to equal
five characters. The module name DFSMShsm traces actually starts on
the fourth character of the true name. The following examples help
illustrate this:
The LOGIC(aaaa[,bbbb,cccc,....]) option looks at the logic fields of the trace entries and selects only those that match one of the logic types you select. Up to 10 logic types may be specified in this option. Each type must contain four characters, with each type separated by a comma in the case of multiple entries. Three especially useful ones are MESG, TIME, and ENTR. Logic types are displayed under the LOGIC column in the trace output display. The SCAN(data) option selects records that contain any reference to data you specify in the data field. The data may match parameters, such as data set names or a key to a data set record. For example, to select all records in which a particular data set name appears, specify the following parameter: SCAN(your.data.set.name). The RECYCLE option selects records related only to RECYCLE activity. |
