问题
GoldenGate的 ggserr.log 日志文件包括有关 GoldenGate 事件的信息,比如:进程启动,关闭,error ,warning。该文件可能会变的很大。为了循环使用该文件,你不得不停止所有的GoldenGate进程。
解决方案:
1.有一个需求是:在GoldenGate进程运行时,循环使用ggserr.log,在此种情况下,你可以用如下的方法:
1). Back up the "ggserr.log" file using the following command: cp -p ggserr.log ggserr.log.bkup 2). Truncate the file using the following command: cat /dev/null > ggserr.log
注意:
在windows环境中, 需要使用unix 模拟器(比如cygwin)来完成上述操作。
如果ggserr.log很大,上一步可能需要很长时间,在此时间之内,注意,这个时间是指在1)和2)之间存在时间差,在step1 和step2之间插入的条目会丢失。
如果要求不能丢失任何条目,那么在ggserr.log最末尾的行(指在step1和step2之间新插入的行)可以被再次备份。
例子:
tail -500 > ggserr.log.bkup_2
对于veridata:
Similar functionality is available for the Veridata veridata.log.
See note 1385983.1 for details.
2. 另外的一个解决方案是 use logrotate (note 1466849.1)

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.

In Oracle, the FOR LOOP loop can create cursors dynamically. The steps are: 1. Define the cursor type; 2. Create the loop; 3. Create the cursor dynamically; 4. Execute the cursor; 5. Close the cursor. Example: A cursor can be created cycle-by-circuit to display the names and salaries of the top 10 employees.

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
