我在Windows服务器上安装了XAMPP。 我的服务器有2份申请:
第一应用程序:PHP和MySQL应用。 这项申请在链接/网页之间迅速运行,等待时间。
第二次应用: PHP和Oracle应用程序。 我使用“Windows(32 bit)的Oracle Instant的客户(OCI)”连接Oracle服务器(另一个机器)。 我有8个表格,每个表格最多有1,000个浏览数据。 我的询问非常简单。 在查询我的Oracle数据库时,每一件事都是正确的。
但是,有时我等待超过20秒的页/链接。 翻开网页的时间太长。 这主要发生在首次进入该网站时。 此外,在一页等候5-10分钟后,试图点击另一页或申请链接。
在使用奥科公司连接Oracle数据库时,我如何减少或终止这一拖延?
你是如何连接的? 如果你使用社会——连接,那么这个问题很可能是一大部分——转向社会——连接。
否则,确实可以确保二者均可获得国家航空航天局的A和PTR记录(或确保你只使用管道地址,而不是姓名连接)。
