Saving system information

Use the Save system information (SAVSYSINF) command to perform a partial save of the data saved by the Save system (SAVSYS) command.

Note:
  1. The SAVSYSINF command increases the time and complexity it takes to recover your system.
  2. Do not use the SAVSYSINF command as a replacement for the SAVSYS command, and do not use it for a system upgrade or migration. You must have performed a successful SAVSYS before using this command.
  3. The SAVSYSINF command is only intended for customers who cannot bring their system to restricted state and take the necessary downtime it takes to perform a SAVSYS command. A SAVSYSINF should be considered a "partial" of a complete SAVSYS. During a complete system recovery the SAVSYSINF save will also need to be recovered along with the complete SAVSYS.
  4. If you are using the SAVSYSINF command in your backup strategy, the PTF save files must remain on the system until the next SAVSYS command is run. For the Restore System Information (RSTSYSINF) command to recover the system to the current state, SAVSYS requires the PTF save files for all operating system PTFs that have been applied after the last SAVSYS command was run. Do not run the Delete Program Temporary Fix (DLTPTF) command unless you run it just before or after the SAVSYS command. For more information see Clean up fixes.

*SAVSYS or *ALLOBJ special authority is required to use the SAVSYSINF command. You cannot restore a SAVSYSINF to another existing system. You can use the SAVSYSINF for system recovery when you are recovering a system using the SAVSYS and SAVSYSINF media. The data saved by the SAVSYSINF is cumulative from the last SAVSYS.

When you save your system information by using the SAVSYSINF command, the system saves the following object types from QSYS:

Object types that are saved
*JOBD *JOBQ *EDTD
*JRN *MSGF 1 *SBSD
*CLS *MSGQ *TBL
*IGCTBL *DTAARA *CMD 1
1 objects changed since the last SAVSYS

Additional items that are saved include the following:

Additional items that are saved
System reply list Service attributes Environment variables
Most system values Network attributes

PTFs applied since the last SAVSYS operation 1 for 5770-SS12 and 5770-999

1 If you load PTFs, you must copy them into *SERVICE. This enables SAVSYSINF to find the save files of the PTFs. The Copy PTFs (CPYPTF) service attribute specifies whether to copy PTF save files into *SERVICE when PTFs are loaded from a tape or optical device. Use the CHGSRVA CPYPTF(*YES) command to change the service attribute on your system to copy PTF save files when loading PTFs from media.

2 The SAVSYSINF command saves PTFs for all licensed programs, including 5770-SS1 and 5770-999, which have been temporarily or permanently applied since the last SAVSYS operation. In addition, for loaded PTFs, the IPL action is checked to determine if the PTF should be included. Loaded PTFs, scheduled to be applied at the next IPL, (IPL action 1 or 3) are saved. PTFs scheduled to be removed at the next IPL, (IPL action 2 or 4) are not saved.

Items that are not saved as part of SAVSYSINF command include the following:

Items that are not saved
Licensed Internal Code QSYS library System values that are not saved
Configuration objects (use the SAVCFG command) Security data (use the SAVSECDTA command)  

The SAVSYSINF command might be incorporated into a save strategy once a base SAVSYS in restricted state is successful. It is recommended that a save of the entire system including a SAVSYS be done in restricted state. This can be accomplished by performing a Go Save Option 21, a combination of an Option 22 and 23, or by using the equivalent functions within BRMS.

Once you have a base SAVSYS, you might perform some or all of these save commands to capture changed or updated information:
SAVLIB LIB(*IBM)
SAV OBJ(('/QIBM/ProdData')('/QOpenSys/QIBM/ProdData')) UPDHST(*YES)
SAVSYSINF
These are other save commands that should be used on a daily basis to save user data:
SAVESECDTA
SAVCFG
SAVLIB LIB(*ALLUSR)
SAVDLO DLO(*ALL) FLR(*ANY)
SAV OBJ(('/*')('/QSYS.LIB'*OMIT)('/QDLS'*OMIT)) UPDHST(*YES)
SAVSYSINF

Example SAVSYSINF:

This command saves the system information to the save file named SAVF in library QGPL. The save file will be cleared automatically. Information about what was saved will be written to the first member of the file name OUTPUT in library QGPL. The file and member will be created if they do not exist.
SAVSYSINF DEV(*SAVF) SAVF(QGPL/SAVF) CLEAR(*ALL) 
          OUTPUT(*OUTFILE) OUTFILE(QGPL/OUTPUT)
