Utl-tcp Connection - Oracle Generic Network Error?

Aug 26, 2010

I have a client program that needs to communicate with another server program. My client program is implemented in PL/SQL using utl_tcp running on Oracle 9 while the server program is a 3rd party software running on Windows server 2003.

Basically my client program needs to send a request to the server, waits for the response (wait for the incoming string which ended /w chr(3) ) and then acknowledge (sending chr(6) ).

My problem is that if I wait for the chr(3) and then acknowledge. My send routine (l_sent := utl_tcp.write_text (g_conn, p_content) will raise a Oracle generic network error. It seems like the connection is closed. I checked /w the vendor and they said it might be I am taking too long to response ( I question timeout is the problem). I have also attempted to change my read routine from read_line to read_raw but it only make things worst. I cannot even read the complete string. At least with read_line, I can read back the entire string.

My current work around is to send out the ack before I receive the chr(3) (which is not recommended by our vendor).

Login To Database - Connection Establish Quickly When Count Reduced

Aug 27, 2012

In the recent past we have been observing the DB connection from application to database using ODBC is taking long time. When I fire LSNRCTL SERVICE command, for our instance the ESTABLISHED = count is being shown a huge number like 45000 and even more some times.

When we restart the instance suing shutdown immediate or abort commands. The established connections count is becoming 0 and again getting increased slowly. Once the count is reduced the connections are getting established quickly without any issue.

Client Tools :: Oracle Connection To SQL Server

Mar 2, 2011

I am using dg4msql to connect to SQL server from Oracle(10.2.0.4, with AIX 5.3).

#from my laptop sqlplus (10.2.0.2)

SQL>select count(*) from table1@mssql; #works
SQL>select * from table1@mssql; #ERROR

ORA-28500: connection from ORACLE to a non-Oracle system returned this message:
[Oracle][ODBC SQL Server Driver]String data, right truncation
{01004}[Oracle][ODBC SQL Server Driver]String data, right truncation {01004}

#from my laptop, TOAD
Both queries works fine.

i have compared

"select * from nls_session_parameters;" values , TOAD and sqlpus gives same result.

Client Tools :: Oracle SQL Developer Connection

Feb 1, 2011

I have installed Oracle 11g R1 and have problem in connecting Oracle SQL Developer.

I have given user name: ora; pswd: ora.

In command prompt it works fine if I gave as below.
uid: ora as sysdba
pswd: ora

But when I am trying to connect to Oracle SQL Developer it says TNS listener does not know SID.

So I reinstalled this since i have doubt on myself whether I made mistake first time. Also I have doubt whether the un installation completely clears all the files from Registry. - What should I do to clear all the files from registry when un-installing.

1] What is SID. Is it session ID. If so how to find it.
2] Is there any way to confirm the values such HOST NAME: localhost, PORT: 1521, SID: (By default it has 'xe') which I gave for data base connection are correct.

I tried with SID value:135 (I got this value by executing [Select distinct sid from V$mystat;])

3] Is there any editor for practicing sql & pl sql queries. where I can download it.

Client Tools :: TOAD 9.1 - Show Windows By Connection?

Jan 21, 2008

TOAD 8.6.1 has an option of showing windows by connection. It is useful when there are multiple connections and, choosing one of these, all windows that belong to other connections are minimized.

Its icon looks like this:

Does TOAD 9.1 have the same option? I'm unable to locate it in options, toolbar customizations or elsewhere.

TOAD 9.5 Release Notes document says that "'Connection list' dropdown button has been restored and can be added to the Toad toolbar.". If I understand it correctly, it says that previous version didn't have that dropdown button, but 9.5 does.

In another words ... 9.1 might not have it at all.

Client Tools :: Alter Session Of Connections In JBoss Connection Pool

Aug 23, 2012

We 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?

Export/Import/SQL Loader :: Impdp Network Mode Can Use Bequeath Connection?

Feb 12, 2013

I'm going to import a single database using FS to a RAC on ASM both are in same server running oracle 11.2.0.3. So I was wondering if can I use network link mode of impdp without setting up a listener using 10gb Ethernet interface ?

I don’t want to incur the overhead of the tcp network layer because both DB single and Rac are on the same server.

Client Tools :: How To Capture Error Code In Sqlplus

Sep 10, 2013

I have a .sql file that is used as a wrapper file that when executes within sqlplus (9.2.0.1.0), executes a bunch of .sql files within it. Example below:

WRAPPER.SQL
START D:ScriptsA.sql "'04-01-2012 00:00:00'"
START D:ScriptsB.sql "'04-01-2012 00:00:00'"
START D:ScriptsC.sql "'04-01-2012 00:00:00'"
START D:ScriptsD.sql "'04-01-2012 00:00:00'"
START D:ScriptsE.sql "'04-01-2012 00:00:00'"
EXIT;

Each of the .sql file (A,B,C,D,E) Spools individual output of sql statment within them. Each of the indv .sql file queries different tables with different filters(where) clause.

I would like to capture any error (OS,SQL,DB) into indv error file (A_ERROR.log). The reason being is because later in the process we need to validate if there were any errors before processing and loading the data into our SQL database
