Oracle PRKC-1002错误原因和解决方案
小编在 VMware Server 1.0.8 中安装 Oracle RAC 时, 碰到到了 PRKC-1002 错误:WARNING: Error while copying directory /u01/oracle/product/10.2.0/db_1 with exclude file list null to nodes rac2. [PRKC-1002 : All the submitted commands did not exe
小编在 VMware Server 1.0.8 中安装 Oracle RAC 时, 碰到到了 PRKC-1002 错误:WARNING: Error while copying directory /u01/oracle/product/10.2.0/db_1 with exclude file list ‘null’ to nodes ‘rac2′. [PRKC-1002 : All the submitted commands did not execute successfully]
苦搜细索,最后在 Oracle 技术支持页面找到了问题的原因和解决方案:
Cause:
This is because the date on the local node is higher than the date on the remote node(s).
Solution:
To fix this, set the times of the nodes to be the same. You can do this with “ntpupdate ” to sync the dates.
其实 PRKC-1002 错误关键是解决时间同步问题,尽管我在安装 VMware-tools 之后,勾选 vmware-toolbox 的 Miscellaneous Options 选项,但 node1 的时间还是比 node2 的快十几秒。参考了一下《大话Oracle RAC》这本书,,决定选用 NTP 服务来使时间同步。 刚开始我是用 node1 来做 NTP 服务的,但做完后发现 node1 的时间还是比 node2 的快几秒,为了保守起见, 我用 node2 来做 NTP 服务。
在 node2 用 root 用记编辑 /etc/ntp.conf,加入下面这段
## add for rac
server 127.127.1.0
fudge 127.127.1.0 stratum 11
driftfile /var/lib/ntp/drift
broadcastdelay 0.008
然后在 node1 用 root 用记编辑 /etc/ntp.conf,加入下面这段
## add for rac
server 192.168.1.131 prefer
driftfile /var/lib/ntp/drift
broadcastdelay 0.008
#注意是 127.127.1.0 而不是 127.0.0.1,还有就是 192.168.1.131 是节点一的IP地址
然后在两个节点执行下面的命令使NTP服务启动
# /etc/init.d/ntpd start
若这样还不可以,那就要把安装数据库的 node1 的时间调得比 node2 慢点。

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. Make sure the firewall or antivirus software does not block the connection; 6. Check whether the server is closed; 7. Use RMAN to recover corrupt files; 8. Check whether the TNS service name is correct; 9. Check network connection; 10. Reinstall Oracle software.

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.

To stop an Oracle database, perform the following steps: 1. Connect to the database; 2. Shutdown immediately; 3. Shutdown abort completely.

When Oracle log files are full, the following solutions can be adopted: 1) Clean old log files; 2) Increase the log file size; 3) Increase the log file group; 4) Set up automatic log management; 5) Reinitialize the database. Before implementing any solution, it is recommended to back up the database to prevent data loss.

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

SQL statements can be created and executed based on runtime input by using Oracle's dynamic SQL. The steps include: preparing an empty string variable to store dynamically generated SQL statements. Use the EXECUTE IMMEDIATE or PREPARE statement to compile and execute dynamic SQL statements. Use bind variable to pass user input or other dynamic values to dynamic SQL. Use EXECUTE IMMEDIATE or EXECUTE to execute dynamic SQL statements.
