How To Fix DB11028 - At least one segment has a number of extents exceeding the threshold

DB11028 - Overview

• Message type: E = Error

• Message class: DB11 - Oracle Monitor: messages

• Message number: 028

• Message text: At least one segment has a number of extents exceeding the threshold

What causes this issue?

At least one segment has a number of allocated extents that exceeds the
threshold specified for this node.

How to fix this error?

Start the analysis tool by double-clicking on the current node in the
monitoring tree. This will display a list of all segments that have
more extents allocated than specified by the threshold, as well as the
number of extents each of these segment has.
To reduce the number of allocated extents for a segment, reorganize 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 DB11028 - At least one segment has a number of extents exceeding the threshold ?

  The SAP error message DB11028 indicates that at least one database segment has exceeded the maximum number of extents allowed. This typically occurs in database systems like Oracle or DB2, where segments (tables, indexes, etc.) are stored in extents, which are contiguous blocks of storage.
  
  Cause:
  
  Exceeding Extent Limit: Each segment in the database has a limit on the number of extents it can have. When a segment grows and exceeds this limit, the error is triggered.
  Fragmentation: Over time, as data is inserted, updated, and deleted, segments can become fragmented, leading to inefficient use of space and potentially hitting the extent limit.
  Insufficient Space Allocation: If the initial allocation of space for a segment is too small, it may quickly run out of extents as data grows.
  
  
  Solution:
  
  Increase the Extent Limit: Depending on the database system, you may be able to increase the maximum number of extents allowed for the segment. This can often
