Solutions

3 solutions available

1. Generate Statistics for Missing Objects medium

Manually create or update statistics for tables that are causing the error.

1

Identify the specific database tables for which statistics are missing. This information is usually available in the application logs or the trace files associated with Error 1089.

2

Log in to your SAP HANA database using a suitable client tool (e.g., SAP HANA Studio, hdbsql).

3

Execute the SQL command to generate statistics for the identified table. Replace `YOUR_SCHEMA` and `YOUR_TABLE` with the actual schema and table names.

CALL _SYS_STATISTICS.STATISTICS_RESET('YOUR_SCHEMA.YOUR_TABLE');
CALL _SYS_STATISTICS.STATISTICS_CALCULATE('YOUR_SCHEMA.YOUR_TABLE');

4

Verify that statistics have been generated by checking the system views. Replace `YOUR_SCHEMA` and `YOUR_TABLE` accordingly.

SELECT * FROM _SYS_STATISTICS.TABLE_STATISTICS WHERE SCHEMA_NAME = 'YOUR_SCHEMA' AND TABLE_NAME = 'YOUR_TABLE';

2. Schedule Regular Statistics Collection medium

Configure the system to automatically collect database statistics at regular intervals.

1

Access the SAP HANA Cockpit or SAP HANA Studio.

2

Navigate to the Database Administration or System Configuration section.

3

Locate the statistics collection settings. This might be under 'System' -> 'Administration' -> 'Statistics' or a similar path.

4

Configure a schedule for automatic statistics collection. It's recommended to run this during off-peak hours. You can often specify which tables or schemas to include or exclude.

5

Save the configuration. The system will now periodically collect statistics, preventing the 'Missing Data Statistics Objects' error for most tables.

3. Investigate and Recreate Statistics Configuration advanced

Troubleshoot potential issues with the statistics collector configuration and recreate it if necessary.

1

Check the SAP HANA system logs for any errors related to the statistics collector or its configuration. Look for messages around the time Error 1089 occurs.

2

Access the SQL console and query the system views related to statistics configuration. For example, `M_STATISTICS_CONFIG` might provide insights.

SELECT * FROM M_STATISTICS_CONFIG;

3

If you suspect a corrupted configuration, you might need to reset or recreate the statistics collector configuration. This is an advanced operation and should be performed with caution, ideally during a maintenance window.

4

Consult SAP Notes and documentation for the specific SAP S/4HANA and SAP HANA versions you are using to find procedures for resetting or reinitializing the statistics collector. This often involves system procedures or specific SQL commands.

5

After any configuration changes, schedule a full statistics collection run to ensure all objects are covered.
