The Save System Information 2 command is a front end to the system
SAVSYSINF command. SAVSYSINF saves a subset of the system data saved
by SAVSYS without requiring the system to be in the restricted state,
but requires a more complex recovery scenario. SAVSYSINF2 is
preferable to directly using the system function because SAVSYSINF2
runs SAVSYSINF and then updates a data area in TAASECURE. This
provides a version of the save information which would be lost if the
last SAVSYS was restored.
The information from the data area may be displayed with the
DSPSYSINF2 command.
You must have the save files for PTFs restored to your system.
********************************************************
* *
* Using SAVSYSINF will cause a more complex *
* recovery scenario than the use of SAVSYS. *
* SAVSYSINF should not be used unless you *
* cannot afford the downtime to use SAVSYS. *
* *
********************************************************
A typical SAVSYSINF2 command would be:
SAVSYSINF2 DEV(xxx)
The subset of SAVSYS information would be written to a tape. The
tape will contain a save file. The TAASYSINF2 data area in TAASECURE
would be updated with the save information. The name of the tape
file written is QSAVSYSINF.
Any user can display the save information from the TAASYSINF2 data
area in TAASECURE with:
DSPSYSINF2
SAVSYSINF2 has most of the same parameters as SAVSYSINF. Only a
single device is supported as the amount of data saved will be small.
Optical devices are not supported. The OUTPUT and OUTFILE parameters
are supported by copying from a standard file output to QTEMP.
SAVSYSINF2 Authorization
------------------------
Both the SAVSYSINF and SAVSYSINF2 commands are shipped as *PUBLIC
*USE, but the SAVSYSINF command requires *SAVSYS special authority.
This is checked for within the SAVSYSINF2 processing.
System SAVSYSINF support
------------------------
The purpose of SAVSYSINF is to allow the infrequent use of SAVSYS
which requires the system to be placed in the restricted state. The
majority of information from QSYS (outside of configuration and
security information is saved).
To recover, the user would restore a SAVSYS version and then use
RSTSYSINF to restore the last SAVSYSINF media. There are exceptions
to the recovery scenario which should be reviewed by using the
RSTSYSINF help text.
SAVSYS requires the restricted state and saves the following:
- Saves the Licensed Internal Code
- Saves the QSYS library
Security and configuration information is saved by default, but the
OMIT parameter allows omission. Security and configuration
information can be saved at any time by the commands:
- SAVSECDTA
- SAVCFG
SAVSYSINF may be used without entering the restricted state to save
various object types that are rarely changed in QSYS such as *JOBDs,
*JOBQs, *SBSDs, etc. Also saved are such items as:
- System reply list
- Network attributes
- PTFs applied since the last SAVSYS
For a full discussion of the items saved, see the help text for
SAVSYSINF.
After restoring the TAATOOL and TAASECURE libraries, you could
determine the last use of SAVSYSINF or SAVSYSINF2.
SAVSYSINF writes to the file named QSAVSYSINF and updates the QSYSINF
data area (use DSPOBJD2 to see the last save information).
SAVSYSINF2 escape messages you can monitor for
----------------------------------------------
None. Escape messages from based on functions will be re-sent.
SAVSYSINF2 Command parameters *CMD
-----------------------------
DEV The device name to be used. The special value *SAVF
may be used to save to a save file. It is generally
preferable to save directly to tape so the tape
volume name may be captured.
VOL The volume identifier of the tape. The default is
*MOUNTED. Up to 75 volumes may be entered.
SEQNBR The sequence number to be used as the starting point
of the save. *END is the default. A number
1-6777215 may be entered.
EXPDATE The expiration date if the data is written to tape.
*PERM is the default to permanently protect the
tape. An expiration date may be entered in job
format.
ENDOPT The operation to be performed on the tape when
writing is complete. *REWIND is the default.
*LEAVE or *UNLOAD may be specified.
SAVF If DEV(*SAVF) is entered, a qualified name of a save
file must be entered. The library qualifier
defaults to *LIBL. A specific library or *CURLIB
may be entered.
USEOPTBLK A *YES/*NO option for whether the optimum block size
should be used when writing to tape. Some tape
devices support a larger block size than the basic
32K block size used for Save/Restore. *YES is the
default. *NO may be specified to use a 32K block
size.
CLEAR An option that determines if any active data is
cleared before writing. *NONE is the default which
will prevent writing over active data unless the
tape is positioned beyond the last file.
*ALL may be specified to clear all active data.
*AFTER and *REPLACE may be specified. See the
SAVSYSINF command for a full discussion.
DTACPR Specifies whether data compression should be used.
*DEV is the default to use the device compression
capability. *NO, *YES, *LOW, *MEDIUM, or *HIGH may
be specified. See the SAVSYSINF command for a full
discussion.
COMPACT Specifies whether data compaction should be used.
*DEV is the default meaning compaction will be used
if supported by the device. *NO may be specified to
prevent compaction. See the SAVSYSINF command for a
full discussion.
OUTPUT The type type of output to be created. *NONE is the
default.
*OUTFILE may be entered to create an outfile in
which case the OUTFILE parameter must be entered.
The named outfile must not exist.
OUTFILE The name of the outfile to be output if
OUTPUT(*OUTFILE) is specified. The file must not
exist. The model file is QASAVOBJ in QSYS with a
format name of QSRSAV. The library qualifier does
not default. A specific library or *CURLIB must be
entered.
OUTMBR The name of the member of the outfile to write data
to. The default is *FIRST.
