ORA-01017 with database link

Hi all

I have a small problem, but I can't find the solution yet.

I created a DB1 databaselink: "create public database GO_TO_DB link

connect to TEMP identified by PW_TEMP

using DB2; »

On DB2 I have the TEMP user with password PW_TEMP thanks to subsidies for the TEST table.

In DB2, there is a table "TEST";

I'm logged into DB1 and do: SELECT * FROM TEST; I get: "ora-01017 name username/password invalid; connection refused

ORA-02063 previous line of GO_TO_DB'

messages.

I can connect to DB2 with the TEMP of the user and can select: no problem.

Also, I tried to connect with sqlplus and user TEMP on DB2: no problem.

Connect to DB1 in sqlplus and don't select it * test, I get ora messages too.

Do I did wrong or what I forgot?

Greetz, Cees

This error message means that you have provided the wrong username and password for the database that the DB connection is connected to.

If the password is case-sensitive, you must put quotation marks when you create the DB link.

The name of DB that you provided when you create the DB link could also be referring to a different database than the one you expect. You should check your tnsnames.ora file (or files) to verify this. You can also specify definitively the DB using the syntax ' host: port / SID "instead of a TNS name.

ORA-01017 with managed provider 4.112.3.60. Bug with the ODP on Win 2008 R2?

I have some difficulty with the provider to manage and I can't understand what is causing the problem.
Initially, the managed provider seems to be a drop in replacement for the unmanaged provider. However, when we moved the code to our test environments, the application started fail with an error 'connection refused '.
Our dev machines are 64 bit Win 7 and Win 2008 R2 our test machines. The DEV machines do not have problems connecting to the database with the same connection used in the test environment string. I can connect to the database using sql more with the connection string used in the application.
I'm at a loss on how to trouble shoot this.
Thank you.

I think I know what is happening here. It looks like the algorithm AES is used to encrypt the password when connecting to the database. The implementation of the AES in .NET is NOT FIPS compatible, which causes problems in the public sector (I noticed you were in the Government, as I am). The only way that I was able to work around this problem was put off from the application of the strategies of FIPS (http://msdn.microsoft.com/en-us/library/hh202806.aspx.) The joys of security...

Cannot connect through the ORA-01017 Invalid Username/Password database link

Hello
I have two virtual machines with Oracle 11 g 2 and one with Oracle 12 c installed on RHEL 6
I wanted to install a dblink between the 2, but after you have created the dblink I get error: ORA - 01017 Invalid username/password
Now, I know, the error is clear enough but when I try to connect using netmgr it works
So just to summarize, Oracle 12 c, I'm trying to connect to Oracle 11 g using a DBLINK but I get ORA-01017
Since Oracle 12 c, I created a new service so that I have the remote db alias in tnsname.ora and at the end of the process, when they ask for test connection, I can connect successfully to remote db
Then I created a dblink according to the following:
SQL > CREATE PUBLIC DBLINK LINK DATABASE to CONNECT to
"hr""" IDENTIFIED BY ' password ' with the HELP of 'REMOTEDB ';
If I then select * from employees@dblink, I get the error
What I've noticed, it is that in the 11g (the target machine) I can not connect with OS authentication, don't know if its related
If i: sqlplus / as sysdba I get ORA-01031 insufficient become

You will probably have to create the link without containing the user name and the word in double quotes.

Get ORA-28562 with link of database when select NULL via ODBC

Hello
This is my first post of the time issue in this community. Apologies if this isn't the right place to start and lease let me know where to post this instead.
I have a database link to connect via odbc to Ingres. Everything works as expected but when I try to select ODBC (HS), where the column is NULL, it returns the error:
Select * from mynull@ingres;
ORA-28562: heterogeneous Services data truncation error
ORA-02063: preceding line of INGRES
This is the track that counts:

The values in the table mynull on the side of Ingres is added as follows:
create table mynull (col1 char (1) with the null value);
insert into mynull values (NULL);
The idea is to use the database link to convert the Ingres on Oracle data. I have the tables all created and copied 90% of the data, but stuck with all the data that has NULL values in it. Can someone tell me what I did not right?
Thank you

Hi Mike,.

Thanks for spending the time to answer my question. Just to let you know that I discovered that I need to add this in my hs init file:

HS_FDS_SQLLEN_INTERPRETATION = 32

This solved the problem I have. Now, I get NULL value correctly. Before closing the issue, here is the info you requested. Thanks again for the help.

1. you use DG4ODBC to connect to Ingres? If so, what is the version?

Yes, not sure about the version that is part of the Oracle 12 C.
2. What is the name and the version of the ODBC of Ingres driver that you use?

The driver name is Ingres and version: 3.50.1010.0137

3. What is returned by - describe "mynull"@gtw_link ".

-do not put a semicolon at the end of the describe.

02:04:21 wswmvzwd [SYS] > describe mynull@ingres

Name Null? Type

----------------------------------------------------------------------------------------------------------- -------- ------------------------------------------------------------------------

col1 VARCHAR2(1)

4. what happens if you use NVL in the selection from Oracle?

Previously, it is fixed:

12:15:39 wswmvzwd [SYS] > select * from mynull@ingres;

ERROR:

ORA-28562: heterogeneous Services data truncation error

ORA-02063: preceding line of INGRES

no selected line

Elapsed time: 00:00:00.13

After it is fixed (added HS_FDS_SQLLEN_INTERPRETATION = 32):

12:17:03 wswmvzwd [SYS] > select nvl ("col1", 'NULL') of mynull@ingres;

NVL)

----

NULL VALUE

A

NULL VALUE

5. you have-
HS_FDS_SHAREABLE_NAME = /opt/Ingres/IngresII/ingres/lib/libiiodbcdriver.1.so

-is the Ingres driver or a driver manager libiiodbcdriver.1.so?

Ingres driver
-If the pilot can you confirm it offers the features of driver as Manager?

Yes, I was able to check it out since the Manager ODBC INgres for the test.

6. can you upload a track of comprehensive gateway somewhere so that see us? Use-

HS_FDS_TRACE_LEVEL = 255

for the trace.

Since it is resolved, I'll ignore it. Part of the debugging information is in the original post.

Thanks again Mike, really appreciated.

Try to connect to the database via SQLPlus target using the tnsnames.ora entry: sqlplus bob@remote.

If the target db is 11g, then breaking the password may be the matter. Try placiing the password in quotes when you create the database link.

OEM 12.1.0.3 Setup fails with ora-01017

Greetings,
I'm trying to upgrade my OEM 12.1.0.1 installation at 12.1.0.3. I'm following the instructions in the Oracle Enterprise Manager Cloud control Upgrade Guide and Support Oracle Note 1568143.1. I checked that all the prerequisites are met and have installed patch 11061801 in the repository. The repository and WHO are on different computers. The 12.1.0.1 installation is able to connect to the repository, it worked successfully for some time now. On the SGD server, quit the SGC and Agent and I invoke the 12.1.0.3 installation program. I followed the steps and when it gets to the login page, it fails with ORA-01017. Messages are displayed -
1. check if the SYS password you have entered is valid.
2. check if the REMOTE_LOGIN_PASSWORDFILE database initialization parameter is set to either shared or Exclusive.

The problem has been resolved by recreating the password file. I used the same password. I don't understand yet why however.

strange problem with the database link
Hello world

I have a strange problem with the link of database in Oracle 11 g Express Edition;
There are two computers: computer-server and the client computer. Tnsnames.ora are the same on both computers IE.

CT =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = krzysztof) (PORT = 1521))
)
(CONNECT_DATA = (SERVICE_NAME = XE)
)
)

I created the database link:

Create database link zdalny
Connect to < user_id > identified by < password >
using "CT".

Customer cannot connect with server when I do not use above the command. But when I change 'use' for using "krzysztof:1521" or by using "krzysztof" or "server IP:1521" - everything is ok.

Why I ask. Because in all the materials that I read about Oracle command with the help of "CT" should work correct. But there is no. Do you know why?

Thanks in advance and apologize me for my English.

Rgds
Krzysztof
Here's the tnsnames of your server, but to connect to the oracle server db (any client or to another instance of db oracle), you must install oracle client.
However, in your condition, you want to connect the DB1 Oracle OracleDB2 using a link db, I'm right? In this case you should always set the entry in the tnsnames.ora
To verify that you can connect to Oracle DB2 from DB1 Oracle, you can use tnsping in the command line.
In your case
```
c:\tnsping CT
```

(DESCRIPTION =

)

Check your tnsnames entry in the machine, you are trying to connect to. And check if the tnsping is successful.
Sometimes the error message says not everything, which means that you need to troubleshoot yourself and learn from the experience.
Always in the opposite case, refer to the documentation.

See you soon.

Duplicate database RMAN 11 GR 2 ORA-17627 ORA-01017 RMAN-03009 ORA-17628

Hello

I'm getting ORA-17627: ORA-01017: name of user and password invalid. connection refused when using the RMAN duplicate on the same host using the account Oracle DBA. The system is Linux Oracle and Oracle 11.2.0.1 5.5

I tested the connectivity and passwords and everything works fine. What could be the reason of this problem please?

Details below:

Thank you.

H3. Summary of the solution:

A big thank you to all who responded! The problem is solved finally :-)

The ORA-17627: ORA-01017 has been corrected using the connection string to connect to the target database, instead of target rman / in the command prompt

$ rman
RMAN> connect target sys/password@orcl
RMAN> connect auxiliary sys/password@clonedb
RMAN> duplicate target database to clonedb from active database;

However, there was still another question:

channel ORA_DISK_1: starting datafile copy

RMAN-03009: failure of backup command on ORA_DISK_1 channel at 12/29/2010 14:40:21
ORA-17628: Oracle error 19505 returned by remote Oracle server
continuing other job steps, job failed will not be re-run

The alert.log to the auxiliary database (clonedb) shows:

ORA-27040: create file error, cannot create the file
Linux-x86_64 error: 2: no such file or directory

I fixed the problem by changing the following text in the settings of the clonedb instance file:

* .db_file_name_convert =('+Data/ORCL/','/Scratch/oradata/clonedb/')
* .log_file_name_convert =('+Data/ORCL/onlinelog/','/Scratch/oradata/clonedb/logfile/')

Thank you!

Hi guy,
Please configure the tnsnames and auditor of the target and auxiliary.
That set the script to use OIC to connect in both instances like this:

connect target sys/test@orcl
connect auxiliary sys/test@clonedb

Please after the release.
Kind regards

ORA-28545 on mySQL - Oracle database link

Hi all
I am trying to establish a connection to the mySQL to oracle database.
Oracle database is running on the 64-bit windows 2003 and version 10.2.0.4.0 computer.
My init < dbname > and tnsnames, listner looks like this and I can create links from the database without any problems at all. Also oracle for oracle database links work properly on this machine as well.

There was no HSODBC for Windows 64-bit (take a look in the ORACLE_HOME/bin directory - there is no hsodbc.exe file at all).
You can use product tracking V11.2 DG4ODBC place. 11.2 DG4ODBC was the first certified on 64-bit Windows lets connect you from your Oracle 10.2.0.4 Database 11.2 DG4ODBC which then connects with the 64-bit ODBC driver to the MySQL database.

You only need to make sure to install DG4ODBC 11.2 in its own ORACLE_HOME - do not install it in your 10.2.0.4 already existing directory ORACLE_HOME - otherwise you will corrupt the existing installation of 10.2.

Getting ORA-01017: invalid username/password error only with specific tools
Hello
I'm still a Junior DBA familiar with Oracle. I have difficulties to access one of my databases with tools of TOAD and SQLDetective. When I try to connect to my database using these tools, I get the error:

ORA - 01017: name of user and password invalid. connection refused

Even if the password and user name is correct.

I can correctly connect through other tools like SQLTools and sqlplus. I searched on this problem and I've seen people with the same problems, but I could not find a solution. The strange thing is, I can use TOAD and SQLDetective to connect to other databases with no problems. It seems to be present a specific database.

My database is a database 11g on linux machine. I have clients 9i and 10 g installed on my machine. All my applications use the 9i on my machine home tnsnames.

Any help on this would be greatly appreciated. Thank you.

RGS,
Rob

Hello, if it is 11g, look at the sec_case_sensitive_logon parameter. This default is true, which makes the case-sensitive password. Some tools/applications do a HIGHER or LOWER on the password and so what can the reason for the error

A question about the CREATE DATABASE LINK PUBLIC and ORA-12154 error
Hi all

I have a problem on the public database link creation and I would be grateful if you could kindly give me a helping hand. I have the following connection settings in my
tnsnames.ora file:
```
...
DGPAPROD.WORLD = 
     (DESCRIPTION = 
       (ADDRESS_LIST = 
        (ADDRESS = (COMMUNITY=tcp.world)
          (PROTOCOL=TCP)(HOST=ORASR001)(PORT=1521)
         ) 
       )
       (CONNECT_DATA = (SID = DGPAPROD))
    )
...
```
Having the above mentioned parameters, I can connect to this remote database directly in a SQL * more shell:
```
$ sqlplus username/[email protected]
```
It works pretty well and the connection is established without any problem.

Now, what I want to do is to create a public database of this remote database link to avoid the user/connection of switch for the visualization of the
the content of this database. I proceeded in line with the syntax indicated in the Oracle online documentation:

http://download.Oracle.com/docs/CD/B28359_01/server.111/b28286/statements_5005.htm#SQLRF01205

This is why I run the following to create a public database link
```
CREATE PUBLIC DATABASE LINK SR001_dblink CONNECT TO user IDENTIFIED BY password USING 'DGPAPROD.WORLD';
```
Apparently there is no error and the link is created successfully. However, it cannot resolve the remote host and every time I run this query
(myenterprise is the name of a table in the remote database)
```
SELECT *
FROM myenterprise@SR001_dblink

ERROR at line 1:
ORA-12154: TNS:could not resolve the connect identifier specified
```
What causes this problem?

Thanks in advance,

Kind regards
Dariyoosh
You must have defined DGPAPROD. WORLD in tnsnames.oar on the server where DB is runnig.

primary DB in the role of Eve with ORA-16816: incorrect database role

We have two node RAC of Primary (oraqa) as well as two-node RAC Physicalstandby (orasqa) managed by dataguard broker. Start quick active failover. Version of the database is 11.2.0.3. OS is Redhat 5.3
There are a few days, our primary oraqa switched to orasqa by fast-start failover, and I couldn't get the passage from some network problem.
Today, the network number, and I want to the transition to the orasqa to oraqa.
However, I got this error:
ORA-16816: incorrect database role
a check for database_role in v$ database at orasqa shows that it is read only physical role of Eve.
So now the two oraqa/orasqa are in the physical database role.
How can I solve this problem?
Help is very appreciated.

Note that in his note, where it is a:

change the database for validation at the grade crossing;

This is the step where it converts the physics of the day before in a primary. So I would try to convert the database that was recently in primary mode at the elementary level. If this works, you need to do several switches of newspaper and make sure you have Data Guard work system before retrying the switch.

I had this happen without a broker and you end up with what amounts to two standbys. "change database validation at the primary crossing" in kind of a way to double back to where you started.

If this gives you more trouble, I'd get Oracle support help as soon as POSSIBLE.

Another way to look at

If you were doing this with SQL the brief summary can be:

On primary

1. check switchover_status

2. commit to failover to standby database

3 stop of the database and the Mont as new mode standby

4 reporter the destination of archive remote

At this point, you have in fact two standbys and zero primary.

If your switchover_status gives a wrong answer, you need to return the primary.

So rather than place orders to the other server, you continue on the same server, a double return and you convert to what was again the primary back to a primary.

Then you trouble shoot the issue and try again.

If you use a broker I would not use SQL unless Oracle Support told me to mix of SQL and broker is a bad idea.

How to run DBMS_HS_PASSTHROUGH with the name of the variable database link?
Hello

I want to run some native sql through DBMS_HS_PASSTHROUGH of oracle to sybase.
but the name of the database link is variable, from things as below:
BEGIN DBMS_HS_PASSTHROUGH. OPEN_CURSOR@db_link_name;

where db_link_name is a local variable and pl/sql still communicate compile error.

Have experience with this?

Thank you.
