How To Fix HH063 - Freespace of specified dbspace has reached a critical size

SAP Error Message - Details

• Message type: E = Error

• Message class: HH - (Long) text for check tool 'infcfgcheck'

• Message number: 063

• Message text: Freespace of specified dbspace has reached a critical size

What causes this issue?

The freespace of the specified dbspace has reached a critical size.
The point at which dbspace freespace is regarded as critical and which
error severity category is chosen, depends on the following case
classifications:

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

CAUTION: If the critical dbspace names contains the first fragment
of a table which has fields of the type 'byte' or 'text',
then the fill level displayed is misleading:
These dbspaces always have a gross fill level of (almost)
100%. See Note 83117 if you are using the feature
'table fragmenting'.
Uncritical cases:
-----------------
o Freespace is 500M or more
o Dbspace is called 'rootdbs' and freespace is 20M or more
o Dbspace is not called 'rootdbs', the maximum next extent
size can fit into the freespace, and freespace is
5% or more of the total dbspace size
Warning cases:
--------------
o Dbspace is called 'rootdbs' and freespace is less than
20M, but at least 10M or more
o Dbspace is not called 'rootdbs':
o The maximum next extent size cannot fit into the
freespace, but half of the maximum next extent size
can fit into the freespace
o Half of the maximum next extent size cannot fit into
the freespace, but freespace is 250M or more
o The maximum next extent size can fit into the freespace
and freespace is less than 5%, but at least 2.5% or more
of the total dbspace size
o The maximum next extent size can fit into the freespace,
freespace is less than 2.5% of the total dbspace size,
but at least 250M or more
Error cases:
-------------
o Dbspace is called 'rootdbs' and freespace is less than
10M
o Dbspace is not called 'rootdbs':
o Half of the maximum next extent size cannot fit into the
freespace, and freespace is less than 250M
o Freespace is less than 2.5% of the total dbspace size,
and less than 250M

How to fix this error?

A dbspace can be extended using the (normal) SAP administration tool
SAPDBA (heading 'Dbspace') or with ONSPACES.

• What is the cause and solution for SAP error message HH063 - Freespace of specified dbspace has reached a critical size ?

  The SAP error message HH063 indicates that the free space in a specified database space (dbspace) has reached a critical level. This can lead to performance issues or even prevent the database from accepting new data if the free space is exhausted. Here’s a breakdown of the cause, potential solutions, and related information for this error:
  Cause:
  
  Insufficient Free Space: The primary cause of this error is that the database space has been filled to a critical level, meaning there is not enough free space available for new data.
  High Data Volume: An increase in data volume due to transactions, logs, or other database activities can lead to rapid consumption of available space.
  Inefficient Data Management: Poor data management practices, such as not archiving old data or not purging unnecessary data, can contribute to the rapid filling of dbspace.
  Configuration Issues: Incorrect configuration of the database or the application can lead to inefficient use of space.
  
  Solutions:
  
  
  Increase Database Space:
  
  Add More Space: If possible, increase the size of the dbspace by adding more storage or extending the existing dbspace.
  Create New Dbspaces: If the current dbspace cannot be extended, consider creating new dbspaces to distribute the data.
  
  
  
  Data Archiving:
  
  Implement data archiving strategies to move old or less frequently accessed data to separate storage, freeing up space in the active dbspace.
  
  
  
  Data Purging:
  
  Regularly purge unnecessary data, such as logs or temporary tables, to reclaim space.
  
  
  
  Monitor Database Usage:
  
  Set up monitoring tools to keep track of database space usage and receive alerts before reaching critical levels.
  
  
  
  Optimize Database Performance:
  
  Review and optimize database queries and transactions to reduce the amount of data being written to the dbspace.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or your database management system's documentation for specific commands or procedures to manage dbspace.
  
  
  
  Related Information:
  
  Database Management: Familiarize yourself with the database management tools and commands specific to your SAP environment (e.g., Oracle, HANA, SQL Server).
  SAP Notes: Check SAP Notes for any specific recommendations or patches related to this error message.
  Backup and Recovery: Ensure that you have a backup strategy in place before making significant changes to the database.
  Performance Tuning: Consider performance tuning of the database to improve efficiency and reduce space consumption.
  
  By addressing the underlying causes and implementing the suggested solutions, you can resolve the HH063 error and prevent it from occurring in the future.
