SQL Experts => How to find Oracle path

 

question:
-----------------------------------------------------------
Hi,
How do we find Oracle Path (ORACLE_HOME) directory at the SQL prompt in wondows???

Thanks,
SindhuReddy

-----------------------------------------------------------
answer1:

On Windows:

SQL> host echo %ORACLE_HOME%
E:\oracle\app\oracle\product\10.2



On 10g as SYS:

SQL> var v_value char(70);
SQL> exec dbms_system.get_env('ORACLE_HOME', :v_value);
SQL> print v_value;

V_VALUE
--------
E:\oracle\app\oracle\product\10.2

answer2:

Hi,
Thanx for ur quick reply..But It does't work .Im using 9.2 version & windowa XP.
so pls do let me know the alternate way.

Thanks,

answer3:

If SQL> host echo %oracle_home% didn't produce any results, then you probably don't have it specificially defined in your environement variable.

You could also use:

select substr(file_spec, 1, instr(file_spec, '\', -1, 2) -1) ORACLE_HOME
	from dba_libraries
	where library_name = 'DBMS_SUMADV_LIB';

answer4:

Your last query will not work on 10g XE. It returns a non-existing directory (maybe the ORACLE_HOME of the original developer?)

内容概要:该论文研究增程式电动汽车(REEV)的能量管理策略,针对现有优化策略实时性差的问题,提出基于工况识别的自适应等效燃油消耗最小策略(A-ECMS)。首先建立整车Simulink模型和基于规则的策略;然后研究动态规划(DP)算法和等效燃油最小策略;接着通过聚类分析将道路工况分为四类,并设计工况识别算法;最后开发基于工况识别的A-ECMS,通过高德地图预判工况类型并自适应调整SOC分配。仿真显示该策略比规则策略节油8%,比简单SOC规划策略节油2%,并通过硬件在环实验验证了实时可行性。 适合人群:具备一定编程基础,特别是对电动汽车能量管理策略有兴趣的研发人员和技术爱好者。 使用场景及目标:①理解增程式电动汽车能量管理策略的基本原理;②掌握动态规划算法和等效燃油消耗最小策略的应用;③学习工况识别算法的设计和实现;④了解基于工况识别的A-ECMS策略的具体实现及其优化效果。 其他说明:此资源不仅提供了详细的MATLAB/Simulink代码实现,还深入分析了各算法的原理和应用场景,适合用于学术研究和工业实践。在学习过程中,建议结合代码调试和实际数据进行实践,以便更好地理解策略的优化效果。此外,论文还探讨了未来的研究方向,如深度学习替代聚类、多目标优化以及V2X集成等,为后续研究提供了思路。
