How To Fix DB11022 - The number of segments with too few allocatable extents

SAP Error Message - Details

• Message type: E = Error

• Message class: DB11 - Oracle Monitor: messages

• Message number: 022

• Message text: The number of segments with too few allocatable extents

What causes this issue?

This is the number of segments that can allocate fewer extents than
specified by the preset threshold. Either the storage parameter NEXT is
set too high or there is too little remaining space in the tablespace.
The preset threshold that determines when a segment has too few
allocatable extents is set in the monitoring attribute "Fewest
allocatable extents for a segment" which displays the smallest number
of allocatable extents for any segment whose PCTINCREASE is set to 0.
Since read-only segments do not allocate space, the threshold for this
attribute should be set to at least the number of read-only segments to
ensure that critical alerts will be generated only when read/write
segments have too few allocatable extents.

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
fewer allocatable extents than specified by the threshold. Also
displayed are the number of remaining allocatable extents for each
segment, its tablespace, and its storage parameter NEXT.
To eliminate this problem, either:
Increase the tablepace size by adding another datafile, or
Decrease the size of the segment's NEXT parameter.

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 DB11022 - The number of segments with too few allocatable extents ?

  The SAP error message DB11022, which states "The number of segments with too few allocatable extents," typically indicates that a database segment (such as a table or index) has run out of available extents for allocation. This can happen when the database is unable to allocate additional space for a segment because it has reached its limit or there are insufficient free extents available.
  Causes:
  
  Segment Size Limitations: The segment may have reached its maximum size limit, which can be defined by the database configuration.
  Insufficient Free Space: There may not be enough free space in the tablespace to allocate new extents.
  High Fragmentation: The tablespace may be fragmented, leading to a situation where there are not enough contiguous free extents available for allocation.
  
  Configuration Issues: The database configuration settings may not be optimized for the current workload or data growth.
  
  Solutions:
  
  Increase Tablespace Size: If the tablespace is full, consider increasing its size by adding data
