Specific Phases for ZDO
In addition to the phases of a standard update procedure, the following phases are specific to ZDO:
|
Phase |
Purpose |
Comment |
|---|---|---|
|
PREP_CONFIGURATION/SUMASK_ZDO_CONFIGURATION |
Configuration of ZDO |
The administrator is asked if a system backup needs to be performed during the system restart. For more information, see Backup Strategy for ZDO . |
|
RUN_RSPTBFIL_ZDM_CHECK_BW |
SAP BW Check |
Checks for an active SAP BW system. As a result, the following log messages are possible:
|
|
PREP_GENCHECKS/PARRUN_ZDO_CONSISTENCY_* |
ZDO consistency check for ABAP dictionary objects, database objects, SLT logging tables, and SLT triggers |
The purpose of the check is to detect inconsistencies already in the original system at an early stage as part of the General Checks module. For example, ZDO can only handle database indexes that are defined in the data dictionary. Undefined indexes disappear in the target release when the table is to be cloned. Such indices must be removed directly or defined in the data dictionary using the transactions SE11 or SE14. See also in chapter Known Issues the section . |
|
MAIN_SHDIMP/SUBMOD_SHD2_RUN/GENKEYTRACE |
Test import for ZDO |
Preparation step required for ZDO table classification. |
|
MAIN_SHDIMP/SUBMOD_SHD2_RUN/CHECK4NOTES_TOOL_SHD2 |
Implementation of SAP Notes in the shadow system |
Checks for SAP Note corrections required by SUM in the shadow system. These SAP Notes belong to the target release. |
|
MAIN_SHDIMP/SUBMOD_SHD2_RUN/SUBMOD_LC4BRI_PREP/RUN_RSPTBFIL_ZDM_CLASSIFY |
Table classification to calculate the handling of tables during the ZDO procedure |
In phase RUN_RSPTBFIL_ZDM_CLASSIFY, tables are classified as follows on
how they are handled during the upgrade.
A possible business impact can be estimated with the Impact Analysis. |
|
MAIN_SHDIMP/SUBMOD_SHD2_RUN/SUBMOD_LC4BRI_PREP/RUN_IMPACT_ANALYSIS_ZDO |
Impact analysis by SUM in batch mode |
Analysis of the table classification impact on productive usage statistics regarding tables that are modified by after-import methods. From this phase on, the dialog version of the impact analysis can also be used. For more information, see Impact Analysis Usage. |
|
Start phase: MAIN_BRISETUP/REQ_USER_ROLLOVER_PREP Completed with phase: MAIN_BRITRANS/REQ_USER_ROLLOVER_FINAL |
Rollover to bridge subsystem |
From this point in time, tables classified as Read Only become read-only for the bridge subsystem. |
| MAIN_SWITCH/EU_SWITCH_ZDM |
Smart switch |
SUM renames the original tables classified as Clone tables. |
|
MAIN_SWITCH/SUBMOD_LC4BRI_EXEC/SQLRUNTASK_FDCT_TRANSFER |
Fast data copy transfer |
Creation of live clone tables. |
|
MAIN_NEWBAS/SUBMOD_ZDO_REPLAY/RUN_ZDOREPLAY_REPLAY_LKPM |
Replay phases |
Replay of the changes created during the runtime of phase SQLRUNTASK_FDCT_TRANSFER. |
|
MAIN_POSTPROC/SUBMOD_BRIDGE_POSTPROC/RUN_PREP_CHECK_ILLACCESS |
Illegal access check |
Checks for illegal table access from the upgrade subsystem. |
|
Start phase: MAIN_POSTPROC/SUBMOD_BRIDGE_POSTPROC/REQ_USER_ROLLBACK_PREP If you have chosen in phase SUMASK_ZDO_CONFIGURATION that a backup has to be requested, you are prompted in phase MAIN_POSTPROC/SUBMOD_BRIDGE_POSTPROC/REQ_ZDO_SYSTEM_BACKUP to perform the complete system backup Completed with phase: MAIN_POSTPROC/SUBMOD_BRIDGE_POSTPROC/REQ_USER_ROLLBACK_FINAL |
End of bridge subsystem |
Roll back to the productive system and system restart. The target release becomes active after the system restart. |
