SQL & PL/SQL :: How To Identify Client Fired Query Still Connected To Database
Dec 21, 2011
I need to get a way to find, The client fired the SQL Query is still connected to the database or not. For e.g.
I fire an SQL query using SQL Developer, Query approximately takes 5 mins to complete. As soon as I fire the query SQL devloper hangs and I close it using task manager.
Is there any way I can identify such session where SQL developer fired the query is terminated but the query fired is still running.
I have to identify such Orphan session and terminate it.

I am facing difficulty in connecting Oracle 10g client to Oracle 10g database. Both the machines are in windows xp with service pack-2. The following observations are made in server machine
1. The loopback test of the server is successful.
2. One net service name created in the server end.
3. Database connection is successful with above service name.
4. tnsping <server ip address> is successful
The tnsnames.ora file of the server is
# tnsnames.ora Network Configuration File: C:oracleproduct10.2.0db_1
etworkadmin nsnames.ora
# Generated by Oracle configuration tools.
CONTRACT =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 80.0.28.42)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = cam)
[code]........
the sqlnet.ora file of the server is
sqlnet.ora Network Configuration File: C:oracleproduct10.2.0db_1NETWORKADMINsqlnet.ora
# Generated by Oracle configuration tools.
# This file is actually generated by netca. But if customers choose to
# install "Software Only", this file wont exist and without the native
# authentication, they will not be able to connect to the database on NT.
SQLNET.AUTHENTICATION_SERVICES= (NTS)
NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)
SQLNET.INBOUND_CONNECT_TIMEOUT = 30
The listner.ora file of the server is

# Generated by Oracle configuration tools.
LISTENER =
(DESCRIPTION =

)
When I am connecting the 10g database with 10g client I am getting ORA-12170 error.
Attempting to connect using userid: nss
The test did not succeed.
ORA-12170: TNS:Connect timeout occurred
There may be an error in the fields entered,or the server may not be ready for a connection. How to configure this connectivity.
The client side tnsnames.ora file is as given below

I have a script which connects to Oracle and return 2 date value. few days back the database was down and when the script execute and return same garbage value in the spool file.
I added a exception handler WHENEVER SQLERROR EXIT 1 befor the connection start and after connection start. But in both the case it is also writing to the spool file.
I would like to exit the connection with a value <> 0 if any connection issue happens like (user id, password, database down error type of issue.) No information should go to the spool file
Output=`$ORACLE_HOME/bin/sqlplus -S /nolog << EOF
CONNECT $Usr/$Pwd@$Server
WHENEVER SQLERROR EXIT 1
spool ${ROOT_DIR}/.delta_date.tmp

Whenever there is a change in the c_flag, we need to identify the change and do some processing. How do I identify the change from either 1 to 0 or 0 to 1. The change can be either way. The point of importance is to identify the change.
CREATE TABLE tab1 ( id NUMBER(10) NOT NULL,
description VARCHAR2(50) NOT NULL,
Start_Date DATE,
id_num NUMBER(10),
c_flag varchar2(2));

I am trying to write a code to identify the delimiter in the file ( which is in the form of table(id, raw) in system)then I take this delimiter and pass it as a parameter to SP which perform cleaning of this file(table) and creates another clean table.
The problem I am facing is until now the file was coming with one fixed (TAB) delimiter, but now it has come with different (SPACE), now here I want to develop the code to identify the delimiter place it in a variable an pass this as parameter to cleaning SP.
--here i want to develop code to identify delimiter from hosts_equiv file which has data as below
select * from hosts_equiv where left(raw,1) not in ('#','*') and isnull(raw,'')<>''
Raw id
---------------- ---
hiper USER1 1
hiper2 USER1 2
APX user2 3
Need to identify delimiter between e.g. hiper USER1 and pass it as a parameter to the raw_parse sp
declare Tab varchar(10)
set Tab = char(9)
exec raw_Parse
'hosts_equiv', -- From table ( entire file content is stored as table with Id record no sequence generated)
'CleanedHosts_Equiv', -- To table name, when passed it will clean the from table and places the cleaned data in to_table
[code]....

We have 11.2.0.3 RAC on Oracle Virtual Box,OEL 5.8. Storage is ASM on EMC SAN.Even when the database is not connected to application and thus open but idle and none is working on it, and all other virtual machines are powered off, we are still getting a continuous i/o in SAN.Since I am new to RAC setup I need to know the few things...
1.Is it normal behaviour?
2.If yes, what is the reason of this i/o? Is it due to continuous ping on voting disk?..write in OCR? automatic backup of OCR?

I know how to use database links in various forms, but I've been trying to think through how the authentication works for a connected user link in 11g. If I create the link like this,
create public database link using 'orcl';
then any user can use the link, provided they have an identical username/password in the two databases. With pre-11g passwords, it was understandable: the password was salted with the username, so the hash of the password would be the same in both databases, and I assumed that the logon through the link used some sort of IDENTIFIED BY VALUES mechanism. But in 11g, the salt will different in the two databases. So the hash will be different. And of course Oracle never stores the actual password. So I don't see how the authentication works.

1. I installed oralce with Service_Name=DB1 it works fine,
2. I created another database with dbca named DB2,
3. I connected both system/password@db1 and system/password@db2 without any problem,
4. After rebooting the computer I can connect only the first database DB1 which I installed with Oracle installation. But, I can not connect to the 2nd database which I created with dbca. Error Message Shows: ORA-12514: TNS:listener does not currently know of service requested in connect descriptor
DB1 has no problem I can connect to that, but I can not connect to DB2 after rebooting the system. Now I need to know how to connect to DB2.

I have an update trigger that runs a package when fired. I only want this package to run if it is NOT fired from an Oracle Forms application. Ie. A user might update table ABC from an Oracle Form. In this instance the trigger would fire, but I don't want to run the package within the trigger. If the user logs onto PL/SQL developer and updates the table, the trigger would fire and the package must run.
I was thinking of using the field 'program' from v$session. If it is null (it's being fired from an Oracle Forms application) if it has a value (it's coming from SQL*Plus / Pl/sql Developer).

I have new virtual UNIX machine and I installed oracle client on /usr/lib/oracle. Also I have a oracle database and I am able to connect to this database from my desktop sql developer.
So now I am trying to connect from new UNIX machine. Where I created tnsnames.ora file under /usr/lib/oracle/network/admin and before connecting did export the following
export TNS_ADMIN=/usr/lib/oracle/network/admin
export ORACLE_HOME=/usr/lib/oracle/
export LD_LIBRARY_PATH=$ORACLE_HOME/lib
export PATH=$PATH:$HOME/bin:/sbin:$ORACLE_HOME/bin
export ORACLE_SID=VFIODSD1
when I try
# sqlplus
username :xxxxxxx
password : xxxxxxx
ORA-12545: Connect failed because target host or object does not exist. Not sure what I missed here. using same tns file I am able to connect from sql developer on windows.

I am trying one simple operation on Oracle9i DB. I am exporting a table data and trying to import it back. The triggers associated with the insert operation for this table are not being fired during import. Here is the commandline i am using to achieve the same.
1) Exporting the table data.
$ORACLE_HOME/bin/exp SMS_60/SMS_60 file=callfwd.dmp tables=callFwd_customerList TRIGGERS=Y
2) Importing the same data.
$ORACLE_HOME/bin/imp SMS_60/SMS_60 file=callfwd.dmp tables=callFwd_customerList ignore=Y
Import ends with success with all the rows imported in the table but the triggers associated to this "insert" operation.

In my DB,We have a table rqst_list
Create table rqst_list(id Number, --(PK)
pkg_name varchar2(100),
status varchar2(100))
When a record is inserted into this table(rqst_list), a trigger is fired which calls the package which is there in pkg_name.The function does some function.If there are no exceptions while executing the package, then SUCCESS needs to be updated in the table for the id for which the trigger got fired.I have used AFTER INSERT ROW level trigger.
But,the final UPDATE (UPDATE the rqst_list table to SUCCES/FAILURE)to the base table inside the package is not happening.

On a form I have 2 blocks, shown on different tabs. Relation created by forms wizard. The relation works great when navigating through the blocks, the details for the master are shown fine.
Example for this form is master block is a type of food. Detail block is list of ingredients.When creating a new type of food, if it's = CAKE we insert records based on a select on another table into the ingredients table.Else, the user has to manually create the ingredients.
Upon commit of the form on master block (must be saved to enable detail block tab), the ingredients are not displayed but are there. If I execute query by hitting F8, the records are present.
Why is the populate-details trigger not being fired or what am I missing?

Is there any way to tell what processes/sessions were connected to a DB after I get an ORA 20error. As you can see from the query results below, I did hit the max value of processes but I would like to know when it happen and who was connected.
I realize I can up the value, but before I do that I want to see what caused this to happen.
SQL> select * from v$resource_limit where resource_name in ('sessions', 'processes');
