Alter Session On NLS_DATE_FORMAT Being Ignored
Feb 24, 2011I'm issuing an alter session setting NLS_DATE_FORMAT in a C batch process right after the connection takes place. The format I specify is YYYYMMDDHH24MISS, this is the format used all over the process. In my development environment this works perfectly, but I've had problems in other environments.
CASE A development environment: The process works fine, $NLS_LANG and $NLS_DATE_FORMAT environment variables are not set.
CASE B Test envirnonment 1: The process failed.$NLS_LANG=American_America.WE8ISO8859P1 $NLS_DATE_FORMAT environment variable is not set.For some reason the $NLS_LANG variable seems to have more weight than the alter session command.. why? The process works fine after setting $NLS_DATE_FORMAT to the desired format.
CASE C Test envirnonment 2: The process failed. $NLS_LANG and $NLS_DATE_FORMAT environment variables are not set. Can't get it to work here. why?
SQL & PL/SQL :: Alter Session Number Format?
Dec 20, 2010how to change the default format of a number value using alter session statement?

PL/SQL :: Alter Session Query On Linux?
Nov 1, 2013I was trying to execute below query inside a sql script which is called from a shell script on linux environment. EXECUTE IMMEDIATE 'alter session set events ''10176 trace name context forever'' ';
This thing works at our test environment. But giving error "SP2-0670: Internal number conversion failed" when tried on live(production) environment. What could be the reason? I found another way of writing such queries on net as follows, will it be useful? EXECUTE IMMEDIATE q'|alter session set events '10176 trace name context forever'|
PL/SQL :: Alter Session In Select Statement?
Oct 15, 2012I'm using Oracle SQL Developer and querying on date fields. I use this "alter session" statement to set my default date time format to get my datetime values. My question is, is there a way I can incorporate the following statement into my "select" query so that Crystal can read it? I use the statement below before my select statement to query datetime differences. Problem is, Crystal doesn't like the statement below.
Using TO_CHAR( ) and formatting my date fields that way doesn't work when I have to take the difference between date fields to the minute/second level. That's why I use the alter session command below, but I cannot seem to incorporate it with my select statement as a Crystal data source.
alter session set nls_date_format = 'DD-MON-YYYY HH24:MI:SS'
Forms :: Possible To Alter A Session Within Oracle Form
Sep 3, 2010Is it possible to alter a session within Oracle forms as I get the following error when trying to compile the following block.
BEGIN
EXECUTE IMMEDIATE ( 'alter session set nls_date_format = 'DD-MON-YYYY''');
END;
Error: Encountered the symbol "IMMEDIATE" when expecting one of the following
The basic requirement is to validate a date field on the form against the current system date, but as the form is in format DD-MON-YYYY and the Database on M/D/YYYY I am struggling to compare dates successfully.

Client Tools :: Alter Session Of Connections In JBoss Connection Pool
Aug 23, 2012We have a Data Source with min_pool_size (10) and max_pool_size (20). A Data Source is by default a connection pool. By starting a transaction we are retrieving a connection from the pool (i.e., opening it to retrieve data, perform queries, inserts and updates). Our application server is JBoss. An application workflow uses many transactions to build a product. The same connection is not used by the application for the entire workflow; but, it uses and returns them to the connection pool. We do not use Java syntax like "rs.close():"... this is performed by iBATIS.
On the Linux side when we execute a "ps" command (ps -elf|grep -i ora) we see all the Oracle processes. A further refinement of that command (ps -elf|grep -i local=no)shows a list of the "waiting" connections in the connection pool. The DB may be queried with the following syntax:
SELECT schemaname, sid, serial# FROM gv$session where schemaname = 'APP_USER' order by SID;
A list of connected sid and serial numbers is returned, identifying which connections are in use. From here we are able to force the connection to trace by executing the following:
exec dbms_monitor.session_trace_enable(249, 6595, TRUE, FALSE); ! 249 and 6595 being SID and Serial# from query above
There should be no need to execute the inverse, since the connection is returned to the pool when the transaction is committed or rolled back.
exec dbms_monitor.session_trace_disable(249, 6595);
We are trying to trace in order to use the Quest Benchmark Factory. Their instructions request the following syntax be applied to each session:
alter session set events '10046 trace name context forever, level 4';
and again, the inverse should not be necessary.
alter session set events '10046 trace name context off'
When it became too cumbersome to alter each session as it appeared, we issued an "alter system" to monitor (trace) everything. The trace files filled the disk, and four hours of testing was stopped two hours in. Doing a system level trace is probably not a good idea.
My first inclination was to create a post-logon trigger to set trace in the session; however, these connections, coming from an JBoss connection pool, do not logon each time, and I presume that they are not all the "same session".
We opened a support ticket with Quest last Friday and do not have an answer yet. This was the third ticket with them, the first to get Benchmark Factory installed (the original installer did not work). The second ticket was to setting up a shared directory on Linux with a folder on Windows, a setup configuration required by their tool. The third ticket to address this issue.
They needed to contact "the developers" to answer the last two questions. Their latest suggestion is to fix ticket two so we "won't need to trace" anything. How do I set trace in these connections?

Way To Alter Tablespace
Jan 22, 2013I have issue of TABLESPACES on test instance. Tablespace files are TEMP1,TEMP2 and APPS_UNDOTS1. Initially TEMP1 and TEMP2 were of 4 GB but now the have grown to 32 GB each respectively. Resulting an occupied space of 64 GB on test server. I want to reuse that space on test instance as those tablespaces never crosses used space of 1%. Reason of this problem was my DBA set AUTOEXTEND as ON for tablespaces.

SQL & PL/SQL :: Alter Sequence With No Max Value?

i know we can alter it like :

SQL & PL/SQL :: DDL Trigger After Alter Table
Jul 22, 2010I created a DDL trigger which manipulates columns of a table after an "alter table" statement.
For us this was all the time
"alter table XXX add NEW_COL varchar2(20)"
or
"alter table XXX modify NEW_COL varchar2(20)".
Unfortunatly we have now a requirement which statements "alter table XXX drop NEW_COL varchar2(20)".
My trigger works fine - you see no problem directly after statement execution but the table is then in an invalid status.
The connection will be destroyed after you tried to see the data of this table.
Also the export (creating a dump) will not work.
The problem I see is that I the database will do a "modify" on a column which has internal the status "dropped".
How I can get the information what kind of alter table statement will be executed?
Or is there any chance to select only columns from USER_TAB_COLUMNS without the "dropped" flag?
create or replace trigger TRIGGER
after alter
on SCHEMA
declare
vCharSet NLS_DATABASE_PARAMETERS.VALUE%TYPE;
begin
-- Select all columns of a table
select COLUMN_NAME, DATA_TYPE, DATA_LENGTH
from USER_TAB_COLUMNS
where TABLE_NAME = vTABLE_NAME; ...
-- Loop for all columns from our select
...
vSTATEMENT := 'alter table ' || vTABLE_NAME || ' modify ' || VOBJECTREC.COLUMN_NAME || ' ' || VOBJECTREC.DATA_TYPE || '(' || vNEW_DATA_LENGTH || ')';
--For example:
-- alter table XXX modify NEW_COL varchar2(20)
execute immediate vSTATEMENT;
exception
...
end;

Alter Table Column And Its Contents?
May 4, 2011I have a table with usernames and passwords. The passwords are stored in plaintext. I would like to issue an ALTER command on the password field to store a hash instead, and then repopulate those fields with an encrypted version of the plaintext passwords that were there before.
I would prefer to do this in a procedure, as I am going to perform it in a test environment first, then eventually in the production environment.

How To Monitor ALTER TABLESPACE Ddl Change
Jan 8, 2013I can use trigger to monitor ALTER TABLESPACE ddl statement against a particular tablespace in a schema.
CREATE OR REPLACE TRIGGER HOT_MAIL_DDL_CHANGE
