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。

To query the Oracle tablespace size, follow the following steps: Determine the tablespace name by running the query: SELECT tablespace_name FROM dba_tablespaces; Query the tablespace size by running the query: SELECT sum(bytes) AS total_size, sum(bytes_free) AS available_space, sum(bytes) - sum(bytes_free) AS used_space FROM dba_data_files WHERE tablespace_

There are three ways to view instance names in Oracle: use the "sqlplus" and "select instance_name from v$instance;" commands on the command line. Use the "show instance_name;" command in SQL*Plus. Check environment variables (ORACLE_SID on Linux) through the operating system's Task Manager, Oracle Enterprise Manager, or through the operating system.

Oracle View Encryption allows you to encrypt data in the view, thereby enhancing the security of sensitive information. The steps include: 1) creating the master encryption key (MEk); 2) creating an encrypted view, specifying the view and MEk to be encrypted; 3) authorizing users to access the encrypted view. How encrypted views work: When a user querys for an encrypted view, Oracle uses MEk to decrypt data, ensuring that only authorized users can access readable data.

Uninstall method for Oracle installation failure: Close Oracle service, delete Oracle program files and registry keys, uninstall Oracle environment variables, and restart the computer. If the uninstall fails, you can uninstall manually using the Oracle Universal Uninstall Tool.

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.

Oracle Invalid numeric errors may be caused by data type mismatch, numeric overflow, data conversion errors, or data corruption. Troubleshooting steps include checking data types, detecting digital overflows, checking data conversions, checking data corruption, and exploring other possible solutions such as configuring the NLS_NUMERIC_CHARACTERS parameter and enabling data verification logging.

To create a user in Oracle, follow these steps: Create a new user using the CREATE USER statement. Grant the necessary permissions using the GRANT statement. Optional: Use the RESOURCE statement to set the quota. Configure other options such as default roles and temporary tablespaces.

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.
