My Oracle notes

On this pages is some problems I've had with Oracle and their solutions, hopefully someone else can also find the hints useful :-)

Running a script from the command line

$ sqlplus myuser/mypass@mydb @/tmp/myscript.sql

Listing top tokens in an index

select token_text, token_count
from dr$xml_index$i
where token_count > 100000;

Redefining a job

exec dbms_job.remove(27);
VARIABLE jobno number;

You can then see the jobs running using:

select job, what, failures, broken, next_date, total_time from all_jobs;

Error 46 initializing SQL*Plus

Error 46 initializing SQL*Plus
Internal error

The environment variable http_proxy must be valid, my error was that the $http_proxy was at the time being not valid, what then was needed was to unset the variable

   unset http_proxy

Error 6 initializing SQL*Plus

root@somehost:~# /u01/app/oracle/product/8.1.7/bin/sqlplus "/as sysdba"
Message file sp1<lang>.msb not found
Error 6 initializing SQL*Plus
root@cmstest381:~# /u01/app/oracle/product/8.1.7/bin/sqlplus
Message file sp1<lang>.msb not found
Error 6 initializing SQL*Plus

The environment variable needs to be set:

export ORACLE_HOME=/u01/app/oracle/product/8.1.7

Environment variable cannot be evaluated

ORA-07217: sltln: environment variable cannot be evaluated.

Another environment variable is needed:

export ORACLE_SID=mysid

Getting a sensible date format in SQL*Plus

A thing that bugs, is the standard date format that does not include the time. To set a sensible format, write the following at the SQLPlus command prompt:

alter session set NLS_DATE_FORMAT='YYYY-MM-DD HH24:MI:SS';

Setting the width in SQL*Plus

set lin <width>

Specifying timestamp

select * from mytable
where thetimefield > timestamp'2005-04-14 12:00:00';

Starting a running counter on a given value

drop sequence my_table_seq;
create my_table_seq increment by 1 start with 1000;
