Access database issue in SQL Plus

Hi Friends,
I download a oracle 10g to install sql Plus without create database. (I download client and does not find SQL Plus)
I can ping database server from client PC and also set up a TNS.
However I got a error ORA 12504 --TNS:listener was not start.
I can access database by sql plua from server side. I do not think we need to put a listener file in client PC under admin path.
my database set as RAC module and system as window 2003
how to fix this issue?
Thanks,
JIm

OK, just to be clear, you have a single client machine where you have installed something with the 10g label. Are you saying that you installed the Oracle database bits, but did not create a database? Rather than doing a client-only install? Is there a single Oracle home on the client machine?
And then you have a RAC database running on multiple Windows 2003 servers, right? Is there a listener running for this RAC database? Can you connect to it from other client machines?
Are you certain that the service name you specified in the client machine's tnsnames.ora file matches the service the listener is listening for?

Connect in database default wiht SQL PLUS

Hi
How can I to connect in database default , using SQL PLUS ?
And after I may change conexion with ACCEPT and change PROMPT ?

What is database default? If you mean you do not wish to specify a connection string such as user/pass@connection, just set ORACLE_SID in the environment before going into sqlplus.

You can't issue a SQL*PLus command from a PL/SQL program. If you can tell us more about what you are trying to do, perhaps we can offer a substitute.

HOW TO START MAKING DATABASE USING ORACLE SQL PLUS in 10g?

how will i create database using sql plus?
does the code of sql applicable to it..?
do i have to use the "create db <database name>", use and " create table also,.."
pls help me..
thanks

At dos prompt :
C:\>set ORACLE_SID=<your SID>
C:\>sqlplus / as sysdba
you get connected as sys user. Don't use this connection to create your own objects, create users instead.... but it would be useful to read some documentation, for example Starting SQL*Plus and manuals mentioned there.

Database view without SQL*Plus

Hi,
Is it possible to look at the database wihtout SQL*Plus and modify tables.
Your help is very much appreciated.
Andonny

Certainly. There are a variety of tools/ API's etc which let you do this. SQL*Plus is a common one, but far from the only one.
If you explain a little more about what you're looking to do and what you want out of a tool, folks might be able to offer some suggestions.

How to connect access database through oracle sql prompt

i want to connect access database via oracle , i am trying to import all the data in Access table into oracle table how it is possible .
A.R

The simplest way, if You have already created tables in Oracle DB, is to open the Access MDB, link Oracle tables via ODBC and build a query to append rows reading from Access tables to Oracle tables.
Hope this helps

Language issues in SQL*Plus 8.1.7 for win 2000

Hi,
I installed Oracle Client 8.1.7 /Win 2000 release.
When I use SQL*Plus 8.1.7, I can not type nor read Arabic characters. My Win 2000 has all the Arabic components. And I am using AR8ISO8859P6 character set on both DB and Registry edit.
I feel like it is a bug in SQL*Plus 8.1.7 on win 2000.
Did anyone face such problem?? Do anyone have a solution?
(Note: When I type Arabic characters it is displayed as Latin characters. When I store them in DB and retrieve them from an other application they are retrieved correclty)
null

Hi
I had similar problem with Cyrillic characters on previous version of Oracle on Windows NT 4.0. We could not find good solution for them. Only solution we found was to write sql commands in notepad and send it in SQL*Plus with copy and paste.

Accessing the recyclebin through sql plus

Hi
I have droped a table by mistake and want to see if it in the recyclebin
I cab only use sql scratchpad at the minute on the oracle windows client
when i try to select from the recyclebin it says table doesnt exist
is it in a particular schema?
Thanks in advance

Double post.
dropped a table by mistake
Did you read the link I posted over there? It is all documented:
"RECYCLEBIN is used to control whether the Flashback Drop capability is turned on or off. If the parameter is set to OFF, then dropped tables do not go into the recycle bin. If this parameter is set to ON, dropped tables go into the recycle bin and can be recovered."
http://download.oracle.com/docs/cd/B19306_01/server.102/b14237/initparams175.htm#REFRN10264
YOu, or your DBA will probably have to enable the recyclebin.
What result do you get for:
SQL> show parameter recyclebin
NAME TYPE VALUE
recyclebin string on

Where can I download it?
(I have tried SQL*Plus version 11 and the program said it does not support the connection to Oracle 8i Database)
Thank you very much!

By the way, what's your 8i database release version
SQL> select * from v$version;
Any SQL*Plus of 8i can connect to 8i Database.
Only SQL*Plus of 9.0.1 can connect to 8.1.7 and 8.1.6 Database

How to reference MS Access database in ColdFusion MX 7 on 64-bit Windows

I am migrating customers from:
Windows 2000 Server (fully patched)
Internet Information Services (IIS) 5
ColdFusion 5
to:
Windows Server 2003 Standard x64 Edition (fully patched)
Internet Information Services (IIS) 6 (running in 32-bit
mode)
ColdFusion MX 7 (7.0.2) Standard
Unfortunately, some of these existing customers are still
using Microsoft Access databases instead of SQL Server. Having all
of these existing customers migrate to SQL Server is not yet
practical. On the old Windows 2000 / ColdFusion 5 server, they are
using OLE DB data sources to reference the MS Access databases
using the "Microsoft.Jet.OLEDB.4.0" provider. None are configured
to use ODBC drivers when referencing MS Access or SQL Server.
I have yet to figure out how to get ColdFusion MX 7 to:
- Create a data source that references MS Access databases on
64-bit Windows.
- Reference an existing MS Access data source created with
the 32-bit version of the ODBC Data Source Manager on 64-bit
Windows.
A bit of background information regarding MS Access on 64-bit
Windows:
- At the time of this writing, Microsoft has not
created/released 64-bit drivers for Microsoft Access and it's
unlikely they ever will, for understandable reasons.
- Contrary to seemingly popular belief, the Microsoft Jet 4.0
Database Engine does exist on 64-bit Windows. See the following
regarding version and file location information:
How to obtain the latest service pack for the Microsoft Jet
4.0 Database Engine
http://support.microsoft.com/kb/239114
- You CAN create MS Access based data sources within 64-bit
Windows, but they have to be made using the 32-bit version of "ODBC
Data Source Manager". I'm assuming these DSNs may only be used by
32-bit applications, but I have not tested that theory.
32-bit data sources:
ODBC Data Source Manager:
%SystemRoot%\SysWOW64\odbcad32.exe
Registry location:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\ODBC
Default file DSN directory:
C:\Program Files (x86)\Common Files\ODBC\Data Sources
64-bit data sources:
ODBC Data Source Manager:
%SystemRoot%\system32\odbcad32.exe
Registry location:
HKEY_LOCAL_MACHINE\SOFTWARE\ODBC
Default file DSN directory:
C:\Program Files\Common Files\ODBC\Data Sources
The 64-bit version of "ODBC Data Source Manager" (under
Administrative Tools) only show "SQL Server" and/or "SQL Native
Client" as options when creating new data sources, unless
third-party software is installed that supplies additional drivers.
The 32-bit version of "ODBC Data Source Manager" (by default,
there is no shortcut for this in the Start menu) shows the typical
drivers seen on 32-bit versions of Windows, including SQL Server,
SQL Native Client, Microsoft Access, Excel, FoxPro, Paradox, etc.
When using ColdFusion Administrator in ColdFusion MX 7.0.2 in
64-bit Windows 2003 (IIS is running in 32-bit mode to allow
ColdFusion MX 7 to function at all), two problems are encountered
when dealing with MS Access (and presumably other 32-bit drivers).
In both cases, ColdFusion is trying to reference the registry
location for 64-bit data sources instead of 32-bit:
1. Creating a new data source within ColdFusion
Administrator:
Data Source Name: whatever
Driver: Microsoft Access
CF Data Source Name: whatever
Database file: (physical path to whatever.mdb)
(other settings are irrelvant for this example)
Error generated when submitting:
Unable to update the NT registry.
Cannot open HKEY_LOCAL_MACHINE\SOFTWARE\ODBC\ODBC.INI\ODBC
Data Sources: Windows error number 5 occurred.Access is denied.
ColdFusion stores the data source, however a "verify"
generates the following error:
Connection verification failed for data source: whatever
java.sql.SQLException: [Macromedia][SequeLink JDBC
Driver][ODBC Socket]internal error: Data source name not found and
no default driver specified
The root cause was that: java.sql.SQLException:
[Macromedia][SequeLink JDBC Driver][ODBC Socket]internal error:
Data source name not found and no default driver specified
2. Creating the data source using the 32-bit version of "ODBC
Data Source Manager" then trying to reference it with ColdFusion:
ODBC Data Source Manager:
System DSN or File DSN:
Name: whatever
Driver: Microsoft Access Driver (.mdb)
Database: (physical path to whatever.mdb)
(creation is successful within ODBC Data Source Manager)
Reference the above DSN within ColdFusion Administrator:
Data Source Name: whatever
Driver: ODBC Socket
Error generated when submitting:
Error accessing available odbc datasources. - Cannot open
HKEY_LOCAL_MACHINE\SOFTWARE\ODBC\ODBC.INI\ODBC Data Sources:
Windows error 2 occurred.The system cannot find the file specified.
ColdFusion MX 7 can't find the 32-bit data source on 64-bit
Windows because it's looking for it in the wrong registry location.
Can ColdFusion MX 7 be configured to look in
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\ODBC
instead of
HKEY_LOCAL_MACHINE\SOFTWARE\ODBC
on a 64-bit Windows machine?

Paul,
Thanks for the insight on this. Regarding the initial problem
I ran into with creating Access based DSNs, very early-on, I
noticed there were two different driver options for Access
displayed within ColdFusion MX 7 Administrator:
Microsoft Access
Microsoft Access with Unicode
For reasons I'm am still baffled over, I somehow completely
forgot about and through the wonders of apparent tunnel vision,
completely overlooked the "Microsoft Access with Unicode" driver
option when I was running through my tests.
At your seemingly-obvious suggestion, I created a data source
using the Microsoft Access with Unicode driver and it worked
perfectly fine with the one customer's web site I'm using for
testing (of course, this is a copy--the production site is still
housed on the old ColdFusion 5 server). This obviously doesn't
actually fix the underlying issue with ColdFusion looking in the
wrong part of the registry on 64-bit Windows, but at least when it
comes to dealing with Access databases, your suggestion of using
the Microsoft Access with Unicode driver appears to be a functional
work-around. So long as there aren't any surprises waiting for me,
hopefully this will also work for the remaining ColdFusion sites I
have to migrate that are using Access databases.
Since you mentioned JDBC drivers in comparison with ODBC, I'm
pointing out a couple of references in case they're helpful to
anyone following this thread:
ColdFusion MX 7 - About JDBC
http://livedocs.adobe.com/coldfusion/7/htmldocs/00001736.htm
Types of JDBC technology drivers
http://java.sun.com/products/jdbc/driverdesc.html
http://java.sun.com/products/jdbc/
I don't actually develop anything in ColdFusion, so I'm
dealing with all of this from a server administration standpoint
since we do have some domain hosting customers that do develop or
at least have existing ColdFusion based sites. I am all
too-familiar with the caveats of using Access in any kind of
production or heavily used environment and have spent years keeping
users away from ODBC. For ColdFusion users, that meant creating OLE
DB DSNs and often having to fix poorly written SQL statements and
fixing ColdFusion date-related values and boolean values (the
common problems encountered when switching CF / MS Access users
from ODBC to OLE DB). I can only recall running into problems with
a single SQL Server based ColdFusion site when migrating from ODBC
to OLE DB. That customer never did get their many coding problems
fixed, so they're the only ones still using ODBC in CF. I have no
idea what'll happen when that one site gets migrated over--if it'll
even work. Obviously a lot of things have changed between
ColdFusion 5 and the MX versions that have come along afterward.
Thanks again for the Access with Unicode driver tip and JDBC
info. It looks like I can finally start moving forward again with
the site migration process.

NLSRTL Version 10.2.0.4.0 - ProductionOS is AIX 5.3 for Oracle 10 and AIX 6.1 for Oracle 11.
We are currently in the process of migrating some applications from Oracle 10 to 11. Our admins have setup a new development system for us with an Oracle 11 instance. Regarding performance the new system behaves more or less the same than our old, e.g. when executing SQLs we notice hardly any performance differences and those we find are slightly in favour of the new system.
But now we discovered that the time it takes to establish a database connection via SQL*Plus is longer on the Oracle 11 system. Running the following code
sqlplus -s user/pw@database <<END
quit
ENDa thousand times takes ~60s under Oracle 10 but ~140s under Oracle 11. This may not seem much but we are running a test framework consisting of a bunch of shell scripts where several thousand connections are openend via SQL*Plus to execute some SQLs, so that even this small time difference results in rather huge difference in total runtime. The SQLs themself require roughly the same time in both databases, as already mentioned above they are in fact slightly faster in Oracle 11.
To analyze the time difference I ran a trace for the connect with the following parameters in sqlnet.ora
TRACE_LEVEL_CLIENT=4
TRACE_UNIQUE_CLIENT=ONand found out that there is a time difference of about 70ms during the connect handshake:

(1) [22-MAR-2013 13:33:40:618] nscon: got NSPTRS packetAny ideas what could be the reason for this time difference? Something in our network configuration or something else?

With local connections - I do not think a TCP packet send from an IP to the same IP, leaves the interface as an actual wire protocol/signal. If I'm correct, then running local connection tests will be mostly useless in checking the actual network infrastructure.
Tests 3 and 4 should be showing the same connection times as the same physical network infrastructure is used - only the direction is reversed in the tests.
I would assume that port settings on the switches and interface settings on the routers treat packets equally in both directions between 2 servers. But this could in part explain the problem if this is not the case. In a case of a router for example, the 1st test's ingress interface is the egress interface of the 2nd test (and vice versa). Configurations can differ substantially between interfaces on the same router. Likewise if there is a firewall - as different rule sets are applied in each test and these rule sets could differ.
So I would not be too quick to state that this is definitely not a network problem. But I agree that based on the small percentage difference (assuming comparable tests), it does not look like a network issue.
The next step is to determine what the delay is between the listener accepting the client connection, and the connection being serviced by a dedicated server process.
This will require listener tracing - tracing the time from when the listener accepted the connection (and parsed the TNS connection string), to handing off the connection to the dedicated server process.
As a comparison test, you can also test shared server connections. Dispatcher processes (of the db instance) register themselves with the listener. The shared server client hand off is thus done to an existing server process - no need for the Listener to make a kernel call to load and initialise an executable image.
Shared connections are typically faster than dedicated connections in this respect.
If there is a major time difference, then it means some kind of issue with the listener dealing with dedicated servers as oppose to dispatcher hand off's. As both connections would have had very similar network transit time - which means the connection time difference is related directly to dealing with a dedicated server connection request and hand off.
You can also substitute the oracle executable with a wrapper - and troubleshoot the actual dedicated server startup. I've only done this with Oracle XE 10.2 though and with local IPC connections. Unsure how robust this will be for testing purposes via TCP using 11g.

Create RAC Database Connection in Sql Developer

Hi All,
Can you please let me know how to create a new connection for a RAC Database. When we use the scan IP and service name, it always displays the network adapter could not establish the connection, even though the listener and database are up and running. After repeatedly, trying atlease 20 times, then it will connect to the database. There are no issue while connecting to a single instance database.
Thanks & Regards,
Krishna

Hi Krishna,
You don't give any details about version numbers but, in general, the Basic connection type should work -- there is no need to use TNSNames. If you can connect to the RAC system via SQL*Plus with an EZConnect string, one would hope the same host/port/service works in SQL Developer for a Basic connection type. But that may be just a hope, I suppose, depending on your overall configuration for SCAN. Or perhaps you pass the full TNS descriptor to connect to SQL*Plus?
In case of long thin RAC JDBC URL, presumably you mean including the full TNS descriptor in the url. I really did not find very much on the forums regarding SCAN, but searching more widely on the internet I note someone resolving a JDBC-specific issue (where SQL*Plus connects just fine) with comments like this: +"The host name in the connectiong string be the same as the init.ora parameter remote_listener and it should also match to the SCAN name. We should not include any domain names with SCAN name , remote_listername and with HOST setting in connecting string"+. So apparently you have to be very careful with the url specification.
Hope this helps,

SQL PLUS Buffer

Hi All,
I need help to display the database buffer in sql plus..........
and how can we access the buffer to get the detail in the buffer
thanks

You can't see the content of the blocks currently cached.
You can read from V$BH the statistics on the blocks stored in the cache.

Semicolon and / in SQL Plus scripts?

Anyone,
Seem to have some confusion over the use of / and ; inside PL SQL Scripts run in SQL Plus.
I seem to get two commits thereby two rows on INSERT clase that has a ; and a /.
i.e.
/* Insert record into table for recording statistics on the runtime of this script */
INSERT INTO MYTABLE ( col1, col2) VALUES ( value1, value2);
COMMIT;
/The above will get two of the same rows in the table. Is this an issue with SQL Plus settings? What do people typically use? I have a combination of SQL and DDL in my scripts and I need / for the DDL typically as I understand. How do othere intermix these and what standard is used.

Dave, here are the very basics.
The SQL language does not have command separators as only a single command at a time can be issued. Thus the following is invalid SQL:
SELECT * FROM emp;
The semicolon as command separator (or terminator) is not valid SQL. This is valid SQL:
SELECT * FROM emp
PL/SQL is a programming language similar to Pascal, C and Java. Multiple commands are used in a program. These need to be separated so that the parser/compiler can know where a command starts and where it ends. In PL/SQL the semicolon is used.
The following is invalid PL/SQL as it is missing command separators:
declare
i integer
begin
i := 1234
endThe following is valid PL/SQL :
declare
i integer;
begin
i := 1234;
end;SQL*Plus is an Oracle CLI (command line interface) client. It can submit both SQL and PL/SQL to the database. It needs to know when you have stopped entering commands into its input buffer and to submit what you've entered to the database.
SQL*Plus uses two characters for this. The semicolon and the forward slash. If you want to submit the above SELECT to Oracle using SQL*Plus, SQL*Plus needs to know when to submit its input buffer's content - thus:
SQL> SELECT * FROM emp;
Or:
SQL> SELECT * FROM emp
SQL> /
When using PL/SQL in SQL*Plus, SQL*Plus "understands" that the semicolons you use are for the PL/SQL language - not an instruction from you to it to submit its buffer to Oracle for execution.
The forward slash can also be at anytime used to resubmit the current SQL*Plus input buffer again. E.g.
SQL> SELECT * FROM emp;
.. now do the last SQL (or PL/SQL) in the buffer again
SQL> /[i]
