Removing entries from the transaction partner log

You can remove entries from the transaction partner log file. To do this, set the REMOVE_PARTNER_LOG_ENTRY custom property for the transaction service on the server that owns the partner log.

About this task

As part of the transaction recovery process, the partner log is checked to establish which resources are needed. If you want to remove certain entries from the partner log, such as a resource that no longer exists, set this custom property on the application server that owns the transaction partner log containing the entries you want to remove.
The REMOVE_PARTNER_LOG_ENTRY custom property is effective only when both of the following situations apply.
  • The application server is started in recovery mode.
  • The application server has no transactions that currently require recovery. You can establish this by checking the SystemOut.log file.
Note: 這個主題參照一或多個應用程式伺服器日誌檔。 此外,在分散式和 IBM® i 系統上,另外也建議您可以配置伺服器來使用「高效能可延伸記載 (HPEL)」日誌和追蹤基礎架構,而不使用 SystemOut.logSystemErr.log, trace.logactivity.log 檔案。HPEL 與原生 z/OS® 記載機能也可以一起使用。如果您使用 HPEL,則可以從伺服器設定檔 bin 目錄,利用 LogViewer 指令行工具來存取您所有的日誌和追蹤資訊。請參閱有關利用 HPEL 疑難排解應用程式的資訊,以取得更多使用 HPEL 的相關資訊。
Note: You can remove transactions from tables that have multiple transactions. Multiple transactions logs within a single database table influence database deadlocks. If there are issues with a specific JVM transaction log, you can remove the specific transaction log entry from the database table utilizing the SQL statement:
DELETE FROM [Transaction Log Table] WHERE
SERVER_NAME=[Cell\Node\Server] AND SERVICE_ID=[SERVICE ID value]

Procedure

  1. In the administrative console, click Servers > Server Types > WebSphere application servers > server_name > [Container Settings] Container Services > Transaction Service > [Additional Properties] Custom Properties.
  2. Click New.
  3. Type REMOVE_PARTNER_LOG_ENTRY in the Name field, and in the Value field, type one or more comma-delimited integer recovery IDs to be removed.
  4. Click Apply or OK.
  5. Save your changes to the master configuration.
  6. Restart the server in recovery mode.
