贵的未必是好的:T5220和X86服务器上Oracle性能之比较

在Solaris上跑Oracle已经10多年了。OS从2.6熬到10,DB从8.1熬到10.2。别说,这种组合还真给力。这么多年,就是没出过啥问题。
3年前的2010年,硬件更新换代。行政上仗着预算富裕,硬是否定了技术人员的升级方案,购买了当时比较高档的T5220。
T5220服务器使用UltraSPARC T2 CPU。该CPU的时钟速度并不高,只有1.2GHz,但是有4个核,而且每个核上可以挂接8个线程,从而构成了32个虚拟CPU。
但是,在此服务器上跑Oracle 10g Standard Edition (10g SE)时,Oracle的每个过程最多只能占有1个(虚拟)CPU的处理能力,也就是最大能使用整个CPU的1/32的能力。
而以前的V240服务器,虽然只有2个物理CPU,但每个过程可独享1个CPU,这就是说最大能使用整个CPU的1/2的能力。
在月末处理时,V240的CPU使用率在1号前后的大约1周时间经常达到80%以上,有时候甚至达到100%。
但是,自从移到T5220后,CPU的最大使用率从来都在18%左右。用户也抱怨这款贵且慢的服务器。
对于多线程,并发处理等,T5220可能比较好,对于处理相对集中的公司业务,T5220不是个好的选择。
为了给行政方面证明以上结论,借用VM服务器的一角,对T5220和X86,就现行的Oracle系统做了一番性能比较。

2.3 C Compiler
SAPRC系统上的C程序在X86上编译/执行未发现问题。
3. HDD的写入速度*
因为使用VM的缘故,X86的写入速度要比T5220慢。
(VM Host服务器使用转速10k的SAS型HDD。)

T5220的处理速度是整个系统的瓶颈。
在X86 CPU上运行在Sparc CPU上的系统未出现功能问题。
本测试中使用的X86服务器比T5220服务器要快得多。

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 the following methods to get time in Oracle: CURRENT_TIMESTAMP: Returns the current system time, accurate to seconds. SYSTIMESTAMP: More accurate than CURRENT_TIMESTAMP, to nanoseconds. SYSDATE: Returns the current system date, excluding the time part. TO_CHAR(SYSDATE, 'YYY-MM-DD HH24:MI:SS'): Converts the current system date and time to a specific format. EXTRACT: Extracts a specific part from a time value, such as a year, month, or hour.

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.

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.

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.

Data import method: 1. Use the SQLLoader utility: prepare data files, create control files, and run SQLLoader; 2. Use the IMP/EXP tool: export data, import data. Tip: 1. Recommended SQL*Loader for big data sets; 2. The target table should exist and the column definition matches; 3. After importing, data integrity needs to be verified.

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.
