Disconnecting in PL/SQL
Greetings All:
I am writing a multithreaded embedded PL/SQL application in Visual C++ 6.0. The application registers as a 'listener' for a dbms_alert from a remote database. It waits for alerts using the waitone(...) method. The problem that I am having is that if I unplug the network cable, the application locks.
What I need is either of the following:
1. I need a way to detect whether a connection still exists using PL/SQL.
2. I need a way to disconnect from Oracle using PL/SQL. I can detect whether a connection has been disabled by using timeouts but I get an error if I try to reconnect because of the multi-threading. So if I can disconnect and reconnect using the same thread, I think I can solve the problem. I just don't know how to disconnect.
Thanks
Mark
Justin:
It is done using Pro*C/C++ precompiler. A file(.pc) is created with the embedded PL/SQL code inside of C++ routines. The precompiler is then run which converts the PL/SQL code into C++ code and generates a .cpp file. The program can then be compiled using the C++ compiler.

Can't disconnect from database connection
Hello,
One of our application has been running for over a year on a client network, a windows desktop executable connected to an Oracle Standard One Edition, rel. 10.1.0.2., on a Linux server. Now the executable hangs when the users exit the app. It is build using Oracle Objects For OLE and the culprit is the close method of the ODatabase object. Strangely however, we found out that other applications cant disconnect anymore:
Both SQL*Plus and Toad will hang when exiting.
Also, doing a connection test with the Net Manager hangs when a valid login is used. If I put an non-existing user or a locked one (scott/tiger for example), the server does report the problem.
I've enabled local client tracing on a user desktop but there are no errors reported, which makes sense since it seems like nothing is coming back.
The network admin over there swears nothing has change on the network config. So Im hunting possible cause for this. There are several logs file cluttering up disk space in various folders and this file:
/home/oracle/OraHome_1/sqlnet.log is now up to 3.1 Mb. I believe I can safely delete this one from other messages I found in various newsgroup. I would be surprise however that disk space is the problem since the windows app works fine, doing query in SQL*Plus works fine. (I only tried Toad to check the disconnect feature, not familiar with this tool, but it was showing the schema correctly)
As a developper, I am however curious on whats happening when a disconnect is sent to the server and what are the expected responses, which dont seem to be coming back anymore. It really looks like some packets are lost on their way back.
Thanks in advance,
EricMany thanks! You hit the problem right on!
Oddly, I can't even drop or disablee the trigger, SQL*Plus freeze. The network admin will perform a shutdown tonite when nobody is using the software. I'll see if I can drop it then.
Regards,

SQL*NET SESSION의 DEAD CONNECTION 처리 방법
제품 : SQL*NET
작성날짜 : 1996-04-03
SQL*NET SESSION의 DEAD CONNECTION 처리 방법
==========================================
server에서 수행 중이던 프로그램이 비정상 종료한 경우에는 오라클의 smon이
자동으로 detection하여 수행 중이던 transaction을 rollback하여
정리하여 준다.
그러나, Client Server 환경에서 PC를 Client로 사용 시 비정상적인 방법으로
Server와 Disconnect 하면 Server 쪽에 있는 Dedicated Server가 남아 있다.
이는 Sql*net V1 & V2에서 발생하던 문제로 Sql*net V2.1 이후에는 아래와
같은 방법을 이용하면 Dead connection이 정상적으로 Disconnect 된다.
* 환경 : Server - Sql*net tcp/ip V2.1.3
Client - Sql*net V2.0
* Setup 방법 : Server와 Client에 있는
$ORACLE_HOME/network/admin/sqlnet.ora에
sqlnet.expire_time=n
으로 setting 한다.
여기서 n은 분 단위이며 실제 disconnect는 n분보다 더 걸린다.
일반적으로 sqlnet.expire_time=1로 설정하면 적당하다.Hi,
Probe send - client and application still there - all fine
Network cable on the client is removedAt the above stage if the Sever sents a probe then if does not receive any message from Client it is treated as DCD. (It will receive any error code or negative response from client instead of any active status communication)
Application is shut down
(Optionally the computer is rebooted)
Network cable is reattached
Next probe send from server
At this point, the client is reachable, the Oracle NET component on the client is there, but the application on the client is gone without properly saying good bye to the DB server.
Would DCD detect the dead connection in this sceanrio?If my above comment is dismissed and your case or assumptions continues, then we need to check the SQL_EXPIRE time which you have connected. If the every thing happens with in the time setted for Expire time then, still it will treat as DCD, your session is getting terminated the system got rebooted.
You understanding with DCD is correct.
We see sessions in V$SESSIONS that don't have a process on the client any more. We have SQLNET.EXPIRE_TIME set to 2 minutes on the server, but still these sessions show up after days. Sessions show up as inactive and are waiting on "SQL*NET message from client" for hours and days.See basically INACTIVE and DCD are different. Slight difference exits. As you said you find inactive sessions. If you want to cleanup those inactive sessions, as per oracle documenation, you can create a custom profile as per your requrement and assign some IDLE_TIME and update the respective user profile. That might help you out.

Connection closed after many connect/disconnect
Hi!
I'm connecting and disconnecting through OCCI many times in short term. After disconnect I run SQL*Loader through system command (in C). When number of that connect/disconnect pair reached about 128 I receive:
SQL*Loader-704: Internal error: ulconnect: OCIServerAttach [0]
ORA-12537: TNS:connection closedWhat should I do to fix this? Maybe some initialize parameter should be changed?You are probably not releasing the connection handles properly.
Most likely that you are holding the 128 connection objects.
terminateConnection should be called before connecting again.
You can see how many connections are active in Oracle Server -
SQLDEV 1.5.5: disconnecting from one db, quits all open editing windows
Hi,
i noticed that in SQL Developer 1.5.5 for Mac OS X, when i disconnect an open connection using the context menu, SQL developer quits all open editor windows even if they are open against different connections.
The windows remain open only if there are unsaved changes and i am asked if i want to save the changes or cancel the operation.
I believe this happened also on 1.5.4, although i could not verify it now.
Flavio
http://oraclequirks.blogspot.com/search/label/SQLDeveloperK,
I understand exactly. When you are connected as a user and have a number of reports, worksheets and other editors open and then disconnect, the reports stay open (we have a preference to control this) and the worksheets stay open ( we have a preference to control this) , but everything else closes. That is because there is no preference and the default behavior is to close the editors. This is as designed. This is a feature that is not implemented and as such is an enhancement request and not a bug. It's still in 2.1 EA1, because we have not yet addressed it. There is no enhancement in our bug database for it. There is a bug that was addressed some years back to ensure that on disconnect the PL/SQL Editors are automatically closed.

ps.
ORA-12154 は整合性の問題であるので、それを合わせれば消えると思っています。
そもそも RAC を前提としていたのですが、それを standalone に置き換えて検証始めた結果、
こうなってしまっています。
open できない原因が ORA-12154 だったりして。。
■ プライマリの場合
○ open するほうは、シンプルに以下だけで open することが確認できる。

ORA-12154 は db が open できない原因とは無関係かもしれない。

This is in reference to the dbassist question that I submitted earlier. This dies when I try to run dbassist. This is on rh6.2 Beowulf on Oracle 8.1.6. Should I try to run the patch for 8.1.5.0.2 ? Anyone know ? I really need to use this tool. Are there any gurus who have the answer?

World record estimation fail. We expect 1 row back, Sql Server expects over 23 trillion! The estimated memory is 111 Petabytes (yes, I said Peta).
We're using a pretty ugly view. Ugly because it has nested views, a correlated subquery and about 20 total joins. On the good side, the call is restricting the view with a single ID against the base table (this is for a single patient). The
rest of the view goes out and gets the patient's address, phone, contacts, status, insurance, diagnosis, etc. The db structure is fairly normalized so that does include about 20 tables.
This is a new application and as such there isn't much data yet. When we run the view on our server with thousands of patients, the results are returned quickly. Query time is subsecond. The execution plan is ugly as expected, it's got
hundreds of nodes, but the cost is pretty low and the performance is acceptable.
When we run the same view on a disconnected device running Sql Server Localdb, it sometimes loses it's mind. Note that the number of patients on the device is rarely over 100, it's a subset of the records on the server. That's when we get the
numbers that I'm quoting above. Basically, the first join thinks there might be 12 records returns, then the next estimates 20 times that many, then 50 times that many, and that number just keeps multiplying until we get to trillions.
I have a screenshot in case anyone thinks I'm exaggerating those numbers. I also have the execution plan XML.
Bottom line is we're going to rewrite the query, but this now becomes an excuse to learn. Where is Grant Fritchey when you need him?In situations like this, there are a few typical situations:
The statistics are stale
You are using parameters and parameter sniffing goes awry
You've hit a bug or flaw in the optimizer
The query can not be properly optimized
The first possible situation is the easiest to find and fix. Simply run UPDATE STATISTICS (preferably WITH FULLSCAN) on each table that is part of the query.
The second situation is also easily testable. For example, you can add OPTION WITH RECOMPILE (or any other relevant Compilation Option) to defeat parameter sniffing.
Of course, you should always check whether you have proper indexes in place. Be aware that Foreign Key relations are not automatically indexed.
If you are out of luck, and it is not any of the first two, then you can dive deeper and find out what is going wrong. If you lack the time or knowledge to do that, you can break the query in several queries and use temporary tables with intermediate results.

Creating Standby database with Oracle 10gR2 SE (no dataguard). Procedure
Hello,
I have problems in creating a standby database without Dataguard (Oracle Standard Edition)
-Oracle 10gR2 SE (No DataGuard !!!!)
- SUSE Enterprise 10.
Both primary and standby databases are running in Virtual machines (lab).
I will describe the exact steps I followed :
1.---------------------------------------------------
Both primary and standby databases have exactly the same file / folder structure
2.---------------------------------------------------
I enabled archive log mode with a new destination : /opt/oracle/oradata/orcl/archive_logs.
Also : SQL> alter database force logging;
3.---------------------------------------------------
I shut down the primary database (shutdown immediate)
4.---------------------------------------------------
I created a standby controlfile on the primary database:
SQL> startup mount
SQL> alter database create standby controlfile as '/tmp/standby.ctl'
SQL> shutdown immediate
5.---------------------------------------------------
I did a cold backup from the primary db to the standby db
(I copied all the db files, control files, redo log)
6.---------------------------------------------------
I copied from the primary db to the standby db the standby control file
(from primary /tmp/standby.ctl)
7.---------------------------------------------------
I copied from the primary db to the standby db the standby control file
(from primary /tmp/standby.ctl)
8.---------------------------------------------------
I created on the standby database a pfile from the spfile :
SQL> create pfile from spfile;
9.---------------------------------------------------
I edited the pfile and changed the controlfile location (with the standby controlfile created in step 4)
>>>>> *.control_files='/opt/oracle/oradata/orcl/standby.ctl'
10.--------------------------------------------------
I started the standby db
SQL> startup mount pfile='/opt/oracle/product/10.2/db_1/dbs/initorcl.ora'
SQL> alter database recover managed standby database disconnect from session;
SQL> quit
11.--------------------------------------------------
I made some changes on the primary db on user scott
SQL> update table set .......
12.--------------------------------------------------
I switched logfile on the primary db
SQL> alter system switch logfile;
13.--------------------------------------------------
I manually copied the new archivelog to the standby db
And then nothing !!!
The db changes are not applied.
Please help me fix the procedure !!!
ThanksHi
Ref to your Oracle SE Standby issue, we were in similar situation couple of years ago to build an Automated Standby for our disaster recovery on Oracle SE. We finally got a solution provider Anbul Technologies , they have a one of their solutions based on Oracle SE which provided fully automated Standby in Oracle SE.
We are successfully running that solution in our prod env for many years. You can visit their site www.anbultechnologies.co.uk or contact them for further details. They are Uk based but provides support and services all over Europe.

ORA-16136: Managed Standby Recovery not active
Hi
I am trying implement the dataguard in the windows platform. And this is my first time. Right now iam trying on physical standby. i have done everything as per the document. But iam getting some error. After giving the

Can somone tell me what the use of Dictionary is?
I am learning from the ADobe Flex store project and they use
a dictionary but i have no idea what the point of using such thing
is, i read the reference document and it doesn't really explain? is
it to basically check if the data is absolutely correct? can i use
something else ? can i get an example of how it differsmeans my variable was pointing to wrong directtory
ORA_NLS10=/aplvol01/CRP/oracle/CRP/db/tech_st/10.2.0/ocommon/nls/admin/data
so i corrected it to “$ORACLE_HOME/nls/data/9idata”,
started the db, it gor started
ran autoconfig and preclone on dbtier
ran the same on appstier
all worked fine..than i broguht down the db gracefully
than started again and it again gave me the following
ORA-01092: ORACLE instance terminated. Disconnection forced on sql main screen
and alert.log
ORA-12701: CREATE DATABASE character set is not known
so i checked again the ORA_NLS10
and it was back to
[oracle@t1 data]$ echo $ORA_NLS10
/d01/oracle/t1/db/tech_st/10.2.0/ocommon/nls/admin/data
can you tell me what wrong here -

Hello!
I have this 2-class package which gets informations on Microsoft SQL Server 2005 tables and table content. It worked perfectly on J2SE 5. Today I moved to Java J2SE1.6 u1 and recompiled the project.

How to open a active dataguard?
Hello,
I have an Active DataGuard, Oracle version 11.2.0.3 and Solaris 10.
I have to do a test on the Active DataGuard environment, I want to open this database to run multiple scripts DML. At the end I must return to the DataGuard active as it was before the opening to continue with normal operation.
I appreciate the document indicate commands or procedure I should run to do this activity.
