How To Fix DB11080 - The number of segments approaching the maximum number of allowed extents

SAP Error Message - Details

• Message type: E = Error

• Message class: DB11 - Oracle Monitor: messages

• Message number: 080

• Message text: The number of segments approaching the maximum number of allowed extents

What causes this issue?

At least one segment has close to the maximum number of extents allowed
in the segment as specified in the storage paramater MAX_EXTENTS.

How to fix this error?

Start the analysis tool by double-clicking on the current node in the
monitoring tree. This will list the affected segments, their
tablespaces, the number of extents currently allocated to each segment,
the value of MAX_EXTENTS, and the number of extents remaining to be
allocated until MAX_EXTENTS is reached.
To eliminate this problem, increase the value of the segments' storage
parameter MAX_EXTENTS or reduce the number of allocated extents by
reorganizing the segment using SAPDBA.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

• What is the cause and solution for SAP error message DB11080 - The number of segments approaching the maximum number of allowed extents ?

  The SAP error message DB11080 indicates that the number of segments in a database table is approaching the maximum number of allowed extents. This situation typically arises in database systems when a table has grown significantly, leading to a high number of segments or extents being allocated for that table. 
  Cause:
  
  Table Growth: The primary cause of this error is the growth of a database table, which can lead to a high number of segments or extents being allocated.
  Database Configuration: The database configuration may have limits on the number of extents that can be allocated to a table.
  Fragmentation: If the database is heavily fragmented, it may lead to inefficient use of space, causing more extents to be allocated.
  Inefficient Data Management: Poor data management practices, such as not archiving old data or not optimizing tables, can lead to excessive growth.
  
  Solution:
  
  Increase the Maximum Extents: If possible, increase the maximum number of extents allowed for the table. This can usually be done through database configuration settings.
  Table Partitioning: Consider partitioning the table if it is very large. This can help manage the data more efficiently and reduce the number of extents.
  Archiving Old Data: Implement data archiving strategies to move old or less frequently accessed data to separate tables or databases, thereby reducing the size of the main table.
  Reorganize the Table: Use database utilities to reorganize or defragment the table, which can help reclaim space and reduce the number of extents.
  Monitor Table Growth: Regularly monitor the growth of tables and set up alerts to take action before reaching critical limits.
  Consult Database Documentation: Refer to the specific database documentation (e.g., Oracle, SQL Server, etc.) for commands and procedures to manage extents and segments.
  
  Related Information:
  
  Database Documentation: Check the documentation for your specific database system (e.g., SAP HANA, Oracle, SQL Server) for details on managing extents and segments.
  SAP Notes: Look for relevant SAP Notes that may provide additional guidance or patches related to this error.
  Performance Monitoring: Use performance monitoring tools to analyze the database and identify tables that are growing rapidly or consuming excessive resources.
  
  By addressing the underlying causes and implementing the suggested solutions, you can mitigate the occurrence of the DB11080 error and ensure better performance and stability of your SAP system.
