• What is the cause and solution for SAP error message RSCV522 - ORACLE: Check in progress; statistics in table &1 are current ?

  The SAP error message RSCV522 indicates that there is a check in progress for a specific table in the Oracle database, and as a result, the statistics for that table are considered current. This message typically arises in the context of database operations where statistics are being gathered or updated.
  Cause:
  
  
  Ongoing Check: The primary cause of this error is that a check operation (such as a consistency check or a statistics gathering operation) is currently being executed on the specified table. This can happen if:
  
  A background job is running that is updating or checking the statistics.
  A manual operation is being performed by a user or administrator.
  
  
  
  Locking Mechanism: Oracle uses locking mechanisms to ensure data integrity during operations. If a check is in progress, the table may be locked, preventing other operations from accessing or modifying the statistics.
  
  
  Solution:
  
  
  Wait for Completion: The simplest solution is to wait for the ongoing check to complete. Once the operation is finished, you should be able to proceed with your intended action.
  
  
  Check Background Jobs: If you have access to the Oracle database, you can check for any running jobs that might be performing checks or gathering statistics. You can use the following SQL query to identify active sessions:
  SELECT * FROM v$session WHERE status = 'ACTIVE';
  
  
  Kill the Session (if necessary): If you determine that the check is taking too long and is blocking other operations, you may consider terminating the session. However, this should be done with caution, as it can lead to data inconsistency or corruption. Use the following command to kill a session:
  ALTER SYSTEM KILL SESSION 'sid,serial#';
  Replace sid and serial# with the appropriate values from the v$session query.
  
  
  Review Database Logs: Check the Oracle alert logs and SAP logs for any additional information that might indicate why the check is taking longer than expected.
  
  
  Consult Documentation: Refer to SAP and Oracle documentation for any specific recommendations or best practices regarding statistics gathering and checks.
  
  
  Related Information:
  
  Statistics in Oracle: Statistics are crucial for the Oracle optimizer to make informed decisions about query execution plans. Regularly gathering statistics helps maintain optimal performance.
  SAP Basis Administration: If you are an SAP Basis administrator, ensure that you have a regular maintenance plan for database statistics and checks to avoid such issues in the future.
  Performance Tuning: If this error occurs frequently, consider reviewing your database performance tuning strategies, including how and when statistics are gathered.
  
  If the problem persists or if you are unsure about taking any actions, it is advisable to consult with your database administrator or SAP support for further assistance.
