How To Fix RSRV582 - Data row compression of InfoProviders in DB2 f. Linux, UNIX and Windows

SAP Error Message - Details

• Message type: E = Error

• Message class: RSRV -

• Message number: 582

• Message text: Data row compression of InfoProviders in DB2 f. Linux, UNIX and Windows

Description
For Fact tables of InfoCubes and aggregates, DataStore object tables and
PSA tables this test checks whether the DB2/UDB row compression feature
has been enabled. With row compression, you can save disk space. The
test determines the following informaton related to DB2 UDB row
compression for each table of an InfoProvider or PSA object that is
eligible to row compression:
Whether row compression is activated or not
The estimated percentage of disk space that could be saved by activating
row compression
The percentage of rows that are ineligible for compression due to snall
rowsize
The size of the compresison dictionary
If compression is activated, the percentage of rows compressed
If compression is activated, the average row compression ratio
The test computes some of the information it provides from the results
of the latest collection of statistics. If the database statistics are
not current the results may be imprecise.
Repairs
This test provides no repair function. Transaction DB6COCKPIT can be
used to activate row compression for tables and generate the compression
dictionary.

This error can arise due to various reasons, including data inconsistencies, issues with the database configuration, or problems with the InfoProvider itself.
  Cause:
  
  Data Inconsistencies: There may be inconsistencies in the data stored in the InfoProvider, which can prevent successful compression.
  Database Configuration: The DB2 database may not be configured correctly for data compression, or there may be limitations on the database side.
  InfoProvider Issues: The InfoProvider may have structural issues or may not be optimized for compression.
  Locks or Transactions: There may be locks on the data or ongoing transactions that prevent the compression process from completing.
  
  Solution:
  
  Check Data Consistency: Use transaction RSRV to check for inconsistencies in the InfoProvider. You can run the consistency checks and resolve any issues that are reported.
  Rebuild the InfoProvider: If the InfoProvider is corrupted, consider rebuilding it. This can involve deleting and re-creating the InfoProvider or reloading the data.
  Database Configuration: Ensure that the DB2 database is configured correctly for data compression. Check the DB2 documentation for specific settings related to compression.
  Check Locks and Transactions: Use DB2 tools to check for any locks or ongoing transactions that might be preventing the compression. Resolve any issues found.
  Update Statistics: Sometimes, updating the statistics of the InfoProvider can help in resolving compression issues. This can be done using the appropriate DB2 commands.
  SAP Notes: Check for any relevant SAP Notes that may address this specific error. SAP frequently releases updates and patches that can resolve known issues.
  
  Related Information:
