在Debian系統更新lsnrctl（Oracle監聽器控制工具）的步驟如下：
listener.ora等關鍵配置文件。sudo cp /path/to/listener.ora /path/to/listener.ora.bak
sudo apt update
lsnrctl：sudo apt install --only-upgrade lsnrctl
lsnrctl）：sudo apt install oracle-instantclient-basic
lsnrctl version
lsnrctl二進制包或Oracle Instant Client包。sudo tar -xvf instantclient-basic-linux.x64-XX.X.X.X.X.zip -C /opt/oracle
sudo ln -s /opt/oracle/instantclient_XX_X /opt/oracle/instantclient
~/.bashrc，添加：export ORACLE_HOME=/opt/oracle/instantclient
export PATH=$ORACLE_HOME:$PATH
source ~/.bashrc
lsnrctl stop
lsnrctl start
或重啟Oracle數據庫服務（若監聽器關聯數據庫）：
sudo systemctl restart oracle-db
libaio等依賴庫（Debian默認可能已包含）。參考來源：
