Authorizations

Authorizations concept in SNP OutBoard™ Housekeeping is based on authorization object /DVD/ERNA. It contains the following authorization fields:

/DVD/FSGRPhousekeeping task group, validated with /DVD/FS_TASKGRP table
/DVD/FSTSKname of housekeeping task, validated with /DVD/FS_TASK table
/DVD/FSACTaction for authorization object, validated with TACT table

It enables to set up of permissions in detail for the activities for a specific task. How-to about setting the authorizations is in Appendix B.

SNP OutBoard™ Housekeeping Global Settings

The settings that control the broader part of SNP OutBoard™ Housekeeping's behavior, are collated within the SNP OutBoard™ Housekeeping global settings screen.

_{SNP OutBoard™ Housekeeping Settings}

SNP OutBoard™ Housekeeping global settings have several tabs: General Settings, System Specific, Task-Specific, User-Specific, and Settings Editor.

General Settings tab

_{SNP OutBoard™ Housekeeping Global Settings – screen}

"Central scheduler" allows (in Edit mode) the user to modify the Scheduler period and information about the next central scheduler run. If the user has the proper authorizations, they may start/stop the central scheduler run. When clicking on the Start button, the user can select if the central scheduler starts immediately or at a specific date/time in the future. If the scheduler is running, first this needs to be stopped to enable the Start button functionality.

_{SNP OutBoard™ Housekeeping Global Settings – central scheduler properties}

Optional "Scheduler user" can be entered to specify a username used for scheduling the tasks. If there is no username selected, the current user is used for background scheduling. Our recommendation is that the selected username is dedicated for scheduling, with an appropriate role /DVD/ERNA_USER (see details in SNP OutBoard™ Housekeeping User role chapter), validity period and it is not assigned to any person. Thus it is independent of any personal changes (company leaves, user locking).
Another parameter that can be changed on the General Settings tab under Advanced Settings, is RFC check timeout: it defines how long SNP OutBoard™ Housekeeping waits for remote systems to respond while checking the sanity of the system.

System Specific tab

_{SNP OutBoard™ Housekeeping Global Settings – System Specific tab}

In the system-specific settings, the user can select specific systems and change the data class where the RecycleBin cluster table is placed. Under the data class selection is possible to select custom data classes on the satellite systems via a list box.
Note: Before executing this action, the RecycleBin must be empty! When a tablespace is changed, Recycle bin table is dropped.

Task-Specific tab

_{SNP OutBoard™ Housekeeping Global Settings – Task Specific tab}

Based on the task type, the user can set up Prefixes for automated task settings generation. These are analysis tasks, that can prepare settings for follow-up tasks; giving the user option to define prefixes for settings IDs.

ID	Description	Default value
TEMSE_DEL	TemSe Objects Cleanup	$TEMSE
CUBE_COMPR	Cube Compression	$CCPR

Archiving task deletion phase – the archiving process has at least two main phases (Write and Deletion phase) that are running independently. The user can specify for any archiving task whether the deletion phase will follow immediately after the execution of the write phase. When there is an archiving session that is incomplete, all subsequent executions of some of the archiving objects would fail. As a result, you now have the possibility to mark complete these previous incomplete sessions prior to the creation of a new session by using the 'Complete incomplete sessions' option.

Object ID	Description
IDOC	Intermediate Documents Archiving
/POSDW/AGG	Archiving of Point-of-Sale Aggregates
/POSDW/TL	Archiving of Point-of-Sale Transactions
BWREQARCH	Archiving of Request Administration Data
RSECPROT	Archiving of BI Authorization Protocols
RSEC_CHLOG	Archiving of BI Authorization Change Logs

The default value is 'X' for all tasks.

User Specific tab

_{SNP OutBoard™ Housekeeping Global Settings – User Specific tab}

"Activity profile" enables the user to select which profile will be active when SNP OutBoard™ Housekeeping starts.

Workbench Logs

The Workbench logs button is found in both the SNP OutBoard™ Housekeeping System and the Activity view. This allows the user to check events that were launched from the SNP OutBoard™ Housekeeping cockpit (i.e. entering the RecycleBin screen, executing the task from the foreground, etc.).

Housekeeping Report

One of the common services SNP OutBoard™ Housekeeping cockpit offers is the housekeeping report. It is accessible from the Goto  Show Report menu. It summarizes information about task runs – short task description, number of runs, and total volume savings for an individual system.

_{Housekeeping report}

History statistics analysis
SNP OutBoard™ Housekeeping is collecting statistics about saved space for each run ID, particularly table and system level. Now high-level information on how much data was cleaned/saved in total is provided for a user to analyze the history.

_{Show statistics in the system view}

From the context menu choose the landscape you want to show the statistics on. The higher the selection in the hierarchy is situated (i.e. landscapes), the more options are available during the selection in the statistics report.
The selection group can be specified by task, system, and date. Date selection allows displaying subtotals and filters statistics by specific period selection. This task can be organized by its group or name. Press Display after filling selections.
The task can be organized by its group or name. Press Display after filling selections.
Results can be organized hierarchically and exported into overviews.

Table Browser

To view which tables are impacted by the SNP OutBoard™ Housekeeping's housekeeping tasks, the user could navigate to the Table Browser, which can be found under Goto.

_{Navigating to view table browser}

In the Table Browser the user can search via tasks or tables:

Search Tables: The user should define the Task Group (Basis, BW, ERP, and CRM, etc.) and the SNP OutBoard™ Housekeeping task (activity), by doing so; the user will see which table(s) will be amended when the Housekeeping Task is performed. If the table exists in the Central system, by clicking the table content button, the user will be redirected to the SE16 transaction for the selected table.
Search Tasks: The user should enter a table name, for the table to be amended by any of the SNP OutBoard™ Housekeeping Tasks (Activities), and the corresponding Housekeeping tasks will be displayed. By clicking on the Info button, the documentation regarding the selected task will be shown. In addition, by clicking the navigation button on the line for a selected task, the task browser screen will close, the cockpit switches to an activity view, the activity profile is switched to "ALL" and the task found in the task browser is focused.

Support for External Scheduler

SNP OutBoard™ Housekeeping supports external schedulers as Redwood, UC/4, Batch man, etc. This is achieved through the envelope report mechanism and can be used to launch SNP OutBoard™ Housekeeping tasks with a selected variant.

Step list

As prerequisites, it is necessary for Global settings to set the value of variable REPLICATE_SETTINGS_TO_VARIANT to "X".
As the next step, go to the settings, which should be used by an external scheduler, and save them. Those settings will be automatically copied to the variant with the same name as Settings ID. That means if the external scheduler will be in use, none of the settings can have the same name. In case the variant already exists within the system with the same name, there will be a message shown.
Variants are created for program /DVD/FS_EXEC_TASK. Afterward, it is necessary to move the variant from the Central system to the target system and run the report /DVD/FS_EXEC_TASK with this variant.

Warning:
SNP OutBoard™ Housekeeping Central system and the external scheduler must be in the same system!
