每当此时,人们就会失去理智,拿起手机对Oracle服务合同怒吼,但这也无济于事。对于Oracle公司来说,当你“永久”购买产品,你就准备与之进行一场持久长跑了。最有效的“终结”就是停止使用该公司产品。
你和销售人员做了哪些的交流互动?或许会出现这么一个场景:你不需要遇见销售代表,也不需要销售技术支持工程。你安排了一个电话会议,在http://meet.oracle.com.网址上登录进入会议 .登录界面如下图所示:

当你看过那些繁文缛节的说明后,最终进入了会议后,销售工程师就会绘制一些图表,标注解释翻译一些没用的东西,好像你刚接触认证似的,或许它们的销售代表是刚接触。事实上,与其你在会议上花费2个小时来处理和绘制那些俏皮的图案,还不如你来巩固服务器和应用程序来节约成本。最后无论是销售代表或是工程师给出的策略就是放弃或者替换许可证。
现在回过头来看,你应该购买什么样的产品以及版本的产品?这个决定是大多数公司都需要做出的,即使现在不做,将来也会要考虑这个问题的。如果你预测公司的用户会有很大的增长,但是不确定的时候,只是建立在预测的基础上时,你是不能容忍,也不能接受几十万美元的成本的。即使十万的费用,也会要再三思考。我个人的建议是花费在认证上的费用可以拿出来购买远程服务。在初期购买阶段最重要的事情就是选择要明智。在这个英明的决定下,你的公司将会存活的更久些。

Solutions to Oracle cannot be opened include: 1. Start the database service; 2. Start the listener; 3. Check port conflicts; 4. Set environment variables correctly; 5.

The method to solve the Oracle cursor closure problem includes: explicitly closing the cursor using the CLOSE statement. Declare the cursor in the FOR UPDATE clause so that it automatically closes after the scope is ended. Declare the cursor in the USING clause so that it automatically closes when the associated PL/SQL variable is closed. Use exception handling to ensure that the cursor is closed in any exception situation. Use the connection pool to automatically close the cursor. Disable automatic submission and delay cursor closing.

Deleting all data in Oracle requires the following steps: 1. Establish a connection; 2. Disable foreign key constraints; 3. Delete table data; 4. Submit transactions; 5. Enable foreign key constraints (optional). Be sure to back up the database before execution to prevent data loss.

Use EXECUTE IMMEDIATE or EXECUTE to execute dynamic SQL statements.

Building a Hadoop Distributed File System (HDFS) on a CentOS system requires multiple steps. This article provides a brief configuration guide. 1. Prepare to install JDK in the early stage: Install JavaDevelopmentKit (JDK) on all nodes, and the version must be compatible with Hadoop. The installation package can be downloaded from the Oracle official website. Environment variable configuration: Edit /etc/profile file, set Java and Hadoop environment variables, so that the system can find the installation path of JDK and Hadoop. 2. Security configuration: SSH password-free login to generate SSH key: Use the ssh-keygen command on each node
