What are the methods for managing E$ tables in ODI, specifically regarding their deletion?

ODI itself doesn't automatically delete E$ tables. These tables act as a historical record of errors and require manual intervention for management. In case you want to delete  E$ tables here are few options

Manual Deletion:

  1. This approach allows you to identify and delete specific E$ tables that are no longer needed. However, it's crucial to be cautious to avoid deleting relevant error data.
    1. Steps:
      1. Connect to your ODI repository database using a tool like SQL*Plus.
      2. Identify E$ tables by searching for table names starting with "E$". You can use wildcards (%) in your search query.
      3. Analyze the data within the E$ tables to determine if they contain valuable error information you still require.
      4. If deletion is appropriate, execute DROP TABLE statements for the E$ tables you want to remove.

Some Important Considerations before you delete E$ tables in ODI:

  • Before deleting E$ tables, ensure you understand the error data they contain and its potential value for future troubleshooting.
  • If you're unsure about the necessity of specific E$ tables, consider archiving them instead of permanent deletion.
  • Always back up your ODI repository before performing manual deletions or using cleanup utilities.
