Use this command to set up and change parameter table default
values.
Requirements and Restrictions
None.
Format
- Note:
- You can also specify the optional parameter names in their abbreviated form
as shown in the syntax diagram.
- ECB-ecb
- specifies the percent of total entry control blocks (ECBs) to be
distributed, where ecb is a value in the range
1-100%. One hundred percent is the total number of ECBs
allocated on the TPF system.
- SETINUSE-
- specifies pool file use, where:
- YES
- calls case 3 of user exit macro DFUEX during the
processing of the RESTORE and VERIFY parameters when pool files are
used. The RESTORE parameter must have the REF and FAD parameters
specified when you use this option.
- Note:
- You can use this parameter only in NORM state.
- NO
- does not call case 3 of user exit macro DFUEX
during the processing of the RESTORE and VERIFY parameters when pool files are
used.
- STATISTIC
- specifies statistics from the parameter table, where:
- YES
- is the file statistics that are built following successful parameter table
processing.
- NO
- is the that file statistics that are not built following successful
parameter table processing.
- PRINT
- specifies the number of messages to be printed to the output device
selected with the ZFCRU OUTPUT command, where:
- prt
- is a number in the range 0-100.
- ALL
- specifies all the messages are to be printed.
Notes:
- Printing will stop when the number you specified is reached.
- Print will stop if the number of messages you specify is less than the
number of messages printed.
- You specify the output device for printed messages with the ZFCRU OUTPUT
command, or with the output parameter settings specified with the ZFCRU SETUP
command.
- The number of messages you specified is in effect only when the
capture/restore utility, information and statistics environment (CRUISE) is in
running state.
- LOGGING
- specifies messages to be logged to the parameter table, where:
- log
- is a number in the range 0-100.
- ALL
- specifies that all the messages are to be logged to the parameter table
logging file.
Notes:
- Logging ends when the specified number of logged messages is
reached.
- Logging will run until available pool space is used if you use the ZFCRU
LOG command with the ALL parameter.
- If the number of logged messages you specify is less than the number of
messages logged, logging will complete and no messages are deleted.
- The number of messages you specified to be logged is in effect only when
CRUISE is in running state.
- OUTPUT-address
- specifies the output device, where address is a 6-digit
hexadecimal printer or terminal address. You can specify as many as
three output addresses.
- Note:
- If you start a CRUISE function from a terminal that is not specified as an
output terminal, only start and end messages are displayed. However, a
prime CRAS receives all messages regardless of where a CRUISE function is
entered.
- TAPE
- specifies the requested tape or general data set (GDS).
- ttt
- specifies any user-defined tape. This must be defined in the tape
label mask record (TLMR).
- TARGET
- specifies the target system where the data will be restored. This
parameter is used for CRUISE capture only. The TPF system is the
default.
- TPF
- specifies the data that will be restored on a TPF system or ALCS
environment.
- MVS
- specifies the data that will be restored on an MVS system.
- RESTORE
- specifies the method in which CRUISE restores data, where:
- OLD
- specifies that the database is restored to the same fixed and pool file
addresses that were captured.
- NEW
- specifies that the captured fixed and pool files are restored to new pool
file addresses where the data structure is rebuilt.
- Note:
- You can use this parameter only in NORM state.
- NOREB
- specifies that the captured fixed and pool files are restored to new pool
file addresses and the data structure is not rebuilt.
- Note:
- You can use this parameter only in NORM state.
- REB
- specifies that the captured fixed files are restored to the same ordinals
that were captured. The captured pool files are restored to new pool
file addresses and the database structure is rebuilt.
- Note:
- You can use this parameter only in NORM state.
- REL
- specifies that old pool file addresses are released when the data
structure is rebuilt.
- Note:
- You can this parameter only in NORM state.
- NOREL
- specifies that old pool file addresses are not released when the structure
is rebuilt.
- Note:
- You can use this parameter only in NORM state.
Additional Information
- During the installation of CRUISE, the initial parameter values are set
according to the values in the C$CRUUSR header.
- You can use the ZFCRU DEFAULT command while the CRUISE function is
processing existing parameter tables; that is, the status of the CRUISE
function is active, running (in use), paused, or stopped. However,
changes that you make to the parameter table by using the ZFCRU DEFAULT
command occur only when new parameter tables are created.
- You must pack a B+Tree and block index file to validate
the file references after CRUISE capture and restore processing because CRUISE
capture and restore processing nullifies the validation of block index
technical LRECs (TLRs) and releases B+Tree files.
Examples
In the following example, the default value for ECBs allocated to CRUISE is
50% of the ECBs allocated to the system.
