sqlplus

I need to write a simple shell function that returns a single field from an Oracle DB. Think of it as for example SELECT 'ABC' FROM dual; and ABC is what I am after. Here is my function: function getSomeOraVal { sqlplus $USER/$PASSWD@$ORADB<<!! SET sqlprompt '' SET sqlnumber off SET verify off SET pages 0 SET echo off SET head on SET feedback off SET feed off SET serveroutput on SET escape '\' VARIABLE v_someVal VARCHAR2(30); BEGIN SELECT 'ABC' INTO v_someVal FROM dual; END; / SELECT :v_someVal FROM dual; !! } However, I want to pipe the sqlplus output (data only -> 'ABC') into a shell

We have the following batch script: ( echo @release.sql echo exit ) | sqlplus x/y@orcl if %errorlevel% gtr 1 goto dberror Issue is - the statement if %errorlevel% gtr 1 never appears to be true when there is a sql error. If we put garbage commands in the release.sql file, sqlplus does complain: SQL> SP2-0042: unknown command "blah" - rest of line ignored. SQL> Disconnected from Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - Production But %errorlevel% still equals 0. How can we determine that there was a sql error? Update : This code DOES appear to work for some sql errors. It

I write: :CREATE TABLE Person ( :name CHAR(10), : :ssn INTEGER); and save it to a file "a.sql" (colon represents beginning of line, is not in actual code.) If I then run it by typing "@a" in the SQL*Plus command prompt, it will tell me that the line starting with "ssn" is not recognized as a command, and is ignored. From what I gather, it seems that sqlplus terminates a command if it encounters multiple newline characters in a row. Is this an accurate statement? If so, does anyone know if this is necessary/ why it chooses to do this? I don't know about the why, but a completely blank line

数据迁移是DBA的日常工作，对于相应的方法、命令等，相信很多人早已了如指掌。圆满的数据迁移流程不单单指将数据从数据库A备份恢复到数据库B，而且要保证迁移前后数据的完整性、服务的可用性。 近日，在给客户做了单机到集群的数据迁移后，发现集群的在线重做日志切换频繁，进而产生了大量的归档日志，对服务器造成了不小的压力。本文是对上述问题的分析处理过程。 发现问题 1. 日志归档频繁 在迁移完成后，需要对集群进行一段时间的深度观察。通过v$archived_log视图，分析数据库历史的归档情况，可以发现整个库的业务活动情况。 观察上图，不难发现迁移（6月15日）前后是一个明显得变化点，每天日志归档频率由原来的100多次变成400多次。这种情况要么是迁入的系统业务量确实很大，要么是迁入的数据库用户配置有问题。 2. 业务情况确认 经过与新迁入系统的运维人员沟通确认，该系统的使用人数虽然多，但都是以查询类的动作偏多，不应该带来这么大量的日志。因为集群中还有其它系统，不能直接判断是新系统的问题。假设运维所说情况属实，那么问题的关键点就是要找到产生大量日志的操作语句，进而找到对应的应用，再确认归档情况是否正常。 问题分析 1. 追根溯源 日志归档频繁，说明在线重做日志切换频繁，一般是由于产生了大量的redo。这里通过awr检查redo的生成情况。 一天内日志归档的详细情况

I would like to get the query execution time in Oracle. I don't want the time Oracle needs to print the results - just the execution time. In MySQL it is easy to get the execution time from the shell. How can I do this in SQL*Plus ? Adam Musch One can issue the SQL*Plus command SET TIMING ON to get wall-clock times, but one can't take, for example, fetch time out of that trivially. The AUTOTRACE setting, when used as SET AUTOTRACE TRACEONLY will suppress output, but still perform all of the work to satisfy the query and send the results back to SQL*Plus, which will suppress it. Lastly, one can
