emacs sqlplus 已断开连接

我开始在 emacs 中使用 sqlplus。它工作正常，除了一件事 - 我经常收到一条消息“Buffer ...没有与任何人交谈”。在文件 sqlplus.el 中，有以下代码用于验证（get-buffer-process process-buffer-name）。如何让sql进程保持活动状态？

(defun sqlplus-verify-buffer (connect-string)
  (let ((output-buffer-name (sqlplus-get-output-buffer-name connect-string))
    (process-buffer-name (sqlplus-get-process-buffer-name connect-string)))
    (when (not (get-buffer process-buffer-name))
      (sqlplus-shutdown connect-string)
      (error "No SQL*Plus session!  Use 'M-x sqlplus' to start the SQL*Plus interpreter"))
    (unless (get-buffer-process process-buffer-name)
      (sqlplus-shutdown connect-string)
      (error "Buffer '%s' is not talking to anybody!" output-buffer-name)))
  t)

I started using sqlplus for emacs. It works fine except one thing - very often I get a message "Buffer ... is not talking to anybody". In a file sqlplus.el there is the following code which verifies (get-buffer-process process-buffer-name). How can I keep alive the sql process?

(defun sqlplus-verify-buffer (connect-string)
  (let ((output-buffer-name (sqlplus-get-output-buffer-name connect-string))
    (process-buffer-name (sqlplus-get-process-buffer-name connect-string)))
    (when (not (get-buffer process-buffer-name))
      (sqlplus-shutdown connect-string)
      (error "No SQL*Plus session!  Use 'M-x sqlplus' to start the SQL*Plus interpreter"))
    (unless (get-buffer-process process-buffer-name)
      (sqlplus-shutdown connect-string)
      (error "Buffer '%s' is not talking to anybody!" output-buffer-name)))
  t)

一种可能的解决方案如下

(defadvice sqlplus-verify-buffer (before sqlplus-verify-buffer-and-reconnect activate)
  (unless (get-buffer-process (sqlplus-get-process-buffer-name connect-string))
    (sqlplus connect-string)))

One possible solution is the following

(defadvice sqlplus-verify-buffer (before sqlplus-verify-buffer-and-reconnect activate)
  (unless (get-buffer-process (sqlplus-get-process-buffer-name connect-string))
    (sqlplus connect-string)))
