Unable to connect to Oracle Applications database (afscpgcs) after clone

Hi,
I have just moved (clone using rapidclone) two of our 11.5.10.2 install from a solaris SPARC 8 to 10 . After the clone, while discoverer 10g works perfectly well in one environment, it is giving the error below in the another environment.
- Failed to connect to database - Unable to connect to Oracle Applications database (afscpgcs)
Notes:
1. For the 2 environments, nothing as changed apart from the hostnames.
2. The password has not changed on both - from source to targets.
3. This happens when launching discoverer 10g from Apps.... discoverer works well on it own if not launched from apps.
I raised a SR with oracle and the 2 things they said have not worked. they said
1. change signon password case parameter - but I cannot find that in the list of system parameters on our system.
2. The other note says apply patch 6430269 and I can confirm this patch has been on the system for sometime.
Please advise on this if you have come accross this before and you can help here.
Thanks

Thanks for your concern. I have used the notes you listed but no luck. One thing I have to point out here is that I have always cloned from solaris 8 to 8 for years without this problem. Now I am cloning from solaris 8 to 10 and the problems is on just one environment. The other is working well. The problem seems to be related to the apps password but the password has not changed at all. Also, I have tried to change the password to something else and ran autoconfig but no luck. Please help

Unable to connect to Oracle Applications database invalid username/password

Hi,
Ou Requirement is we want to connect to Oracle Applications using discoverer plus and discoverer viewer.
Application Server used : 10.1.2.0.2
Oracle Applications : R12 RUP4
We have installed application server 10g with OID and when we try to connect to oracle applications we are getting
A connection error has occurred.
- Failed to connect to database - Unable to connect to Oracle Applications database: invalid username/password.
Regards
Ketan

Hi,
I think better to check with your sysadmin or DBA on this, I had the same isuse before but Apps 11i with Discoverer, I talked to ERP sysadmin and worked fine.
Since applications userid cannot talk with Discoverer schema (eul10_us) and it should directly talk with APPS user and then APPS user can talk with Discoverer user.
To the best of my knowledge I provided.

Unable to Connect to Oracle 10gR1 database from JDeveloper 11g using OCI

We are migrating our application from OC4J to Weblogic server. As a part, I am trying to create a database connection in JDeveloper 11g (11.1.1.3.0 - Build JDEVADF_11.1.1.3.PS2_GENERIC_100408.2356.5660) to Oracle 10gR1 database. Previously I had Oracle 10g Client installed in the machine. Created a database connection using OCI driver and when I try to test connect, I got "Test Failed: no ocijdbc11 in java.library.path". I searched through Metalink and forums and one suggestion was to install Oracle 11g Client on the machine where Jdeveloper 11g is installed. I installed 11g R1 client and tried the same test connection using OCI driver. Now I am getting "Test failed: ORA-12705: Cannot access NLS data files or invalid environment specified" error.
The same database connection works good with Thin driver with both Oracle 10g client and 11gR1 client.
Previously I had Jdeveloper 10.1.3.2 and Oracle 10g Client and I was able to connect to database without any errors.
Could you provide me the steps for this or if I missed any steps?
Steps to Replicate:
For the error: no ocijdbc11 in java.library.path
1) Install JDeveloper 11g (With embedded Weblogic Server)
2) Install Oracle 10g Client on the same machine
3) Create a database connection in the "Application Resources --> Connection"
4) Use OCI driver. Enter the host details about the Oracle 10g R1 database
5) Test connect to the database.
ORA-12705: Cannot access NLS data files or invalid environment specified

4) Use OCI driver. Enter the host details about the Oracle 10g R1 database
5) Test connect to the database.
Note: Tried the same scenarios with Oracle 11gR2 client as well. It was not working at all.
Any ideas and pointers would be great.

1. will my problem get solved after i install oracle 11g client on my machine.Yes, your problem should get solved. The version of the Oracle 11g Client must match the version of the JDev's JDBC drivers. Alternatively you may install an Oracle 11g Client and replace JDev's Oracle JDBC drivers with these from the installed client. Please, read carefully my 1st posting above in this thread.
2. can i patch JDeveloper 11g on my machine to work with 10g client, or can i do the same with 10g client.You might succeed if you replace JDev's built-in JDBC drivers (which are 11g versions) with 10g versions, but I do not recommend you to try that because JDeveloper 11g and ADF 11g may be using some 11g features that do not exist in 10g drivers, so you may have problems.
I also have PLSql developer installed on my machine and it works well.PL/SQL Developer does not use JDBC drivers, so it is not an relevant example in this case.
My generall recommendation is to use Oracle JDBC Thin drivers. Oracle claimed that OCI drivers had better performance, but this was really true about earlier releases. Current Oracle 11g JDBC Thin drivers offer excellent performance and they offer all the features of the OCI versions (which was not true about earlier releases). In my opinion, the most important disadvantage of Oracle JDBC OCI drivers is that most versions have native memory leaks so all the RAM would get consumed after long application execution. The fact that WebLogic Server does not offer Oracle JDBC OCI drivers by default anymore says that Oracle discourages the usage of the OCI driver in favour of Thin driver.

Cannot connect to Oracle express database using Oracle forms 10 on win XP

Hello All,
I have installed Oracle Developer Suite 10g along with Oracle Express edition database on Windows XP home edition. (Do get successful installation message)
When i open up Forms builder and try to use connect option- it comes up with user name, password and database dialogue box?
If I enter user name and password I choose while installation express edition database it comes up with the following error:
"ORA-12560:TNS:protocol adapter error"
Have checked the services and they all seem to be running, have tried deinstalling/installing by removing registry values but still no luck.
In fact what ever I type the error message remains the same.
On the other hand I can access Express edition database using user name and password I choose during its installation.
Can any one please reply me what details i need to enter here? Is it same as I set up during express edition database installation? What about database?
Please help. As I am struggling big time.
Thanks in advance.

You may be having the same problem as this guy:
Forms 6i - ora-012203 tns:unable to connect to the destination
You need to start SQL Plus and see if you can log in, too, to make sure there are not other problems.
What are you using for the Database name (the third entry following username and password)?

Unable to establish a connection to Oracle 9I database from Developer Forms

I've installed the Oracle 9I database in the Windoes NT server with SID = ORA9i. Using the SQL*plus coming with oracle 9I database, I can connect to the database. I've also installed the Developer with Forms 6I and Reports 6I in the same computer. I tried to establish a connection to the Oracle 9I from Developer through "Oracle Net8 Easy Config". After giving the settings, when I do a connection test, it is giving the error "TNS Could not resolve the Service Name".
the following is the entry in the 'tnsnames.ora' file
TEST9I.WORLD =
(DESCRIPTION =
(ADDRESS_LIST = ((PROTOCOL = TCP)(Host = ntserver)(Port = 1521))
(CONNECT_DATA = (SID = ORA9i))
Can somebody tell me how to make a connection from Developer (Forms6I and Reports 6I) to Oracle 9I database.
Thank you.

hi matz,
i tried this one too, but it is not working. giving the same error. if i've making a connection thru the 'Oracle Net8 easy config', it is giving the following error at time of connection test.
The test did not succeed.
ORA-03106: fatal two-task communication protocol error
There may be an error in the fields entered
or the server may not be ready for a connection.
You can check the server and retry, or continue.
this is the message i'm getting. but i couldn't find any error in the fields i entered.
if i'm editing the 'tnsnames.ora' file and make the connection, and when i open the Form builder and try to connect to the database, it is giving a memory error.
the instruction at "0x67614f04" referenced memory at "0x000000160". The memory could not br "written".
i don't know why it is happening. i can connect from the same forms to Oracle 8i database. is there any additional settings we need for Oracle 9i on windows platform?
regards
george

Unable to connect to Oracle XE database

Hello
I have installed the XE database and it is running just fine. I have even been able to create a Discoverer EUL against it and I have no problems.
Today I downloaded Raptor and tried to create a new connection. I followed the instructions here: http://www.oracle.com/technology/products/database/project_raptor/howtos/howto_connect_xe.html
but these do not work. When I click Test ot Connect the system appears to try and connect but then I see this message in red "Status :Failure -lo exception: Got minus one from a read call"
Anyone have any ideas?
Best wishes
Michael

What OS are you running on? I connect to XE every day using v804 and our QA did full certification testing against XE.
I have one connection that is for system (named 'XE-system') and another for my user.
Hostname = 127.0.0.1
Port = 1521
SID=XE

Unable to connect to Oracle 11g server using instantclient_11_1 in AIX

Hi,
I downloaded instantclient-basic-11.1.0.7.0-aix-ppc64.zip from oracle site and used the same for connection to 11g server for testing my application on AIX 5.3 machine. I am also using easysoft driver for the connection. But I am uhnable to connect to Oracle 11g server from AIX 5.3 using instantclient_11_1 client
libraries. I get the error "Could not load oracle libraries". Error is as below:
WARNING: Setup was unable to contact your ORACLE
WARNING: server by using the connection options
WARNING: you specified.
WARNING: Error connecting to DB: -1
WARNING: HY000: [unixODBC][Easysoft][Oracle]Could not load oracle libraries
But I could connect to the same server from AIX 5.3 machine using instantclient_10_2 libraries and same eaysoft drivers successfully.
Looks like there is issue with connecting with instantclient_11_1 client libraries from AIX 5.3. I also tried with using 11.1.0.6.0. Same issue is observed.
Did anybody else face similar issue?
Thanks and Regards,
Prema S
Edited by: user6404935 on Jan 27, 2010 9:47 PM

I you find nobody who has the same problem, here are some hints:
- Try to connect using "sqlplus" from the instant client. If that fails, there is probably a problem with your setup.
- Look if the Easysoft driver supports Oracle 11.1 as client.
Yours,
Laurenz Albe

Is that the only Oracle client installed? If you have another one hanging around it could be using the wrong tnsnames file.

Unable to connect to Oracle using OCI Drivers on Linux

Hi Everyone!
I am facing a peculiar issue while using Instant Client on Linux ( 64Bit ) running on Red Hat 4.1.
I have downloaded the instant client version 10.2.0.3(.zip) .so files from the below URL
http://www.oracle.com/technology/software/tech/oci/instantclient/htdocs/linuxx86_64soft.html
UPloaded all the files to a directory under /opt and changed the .bash_profile file, the latest content looks like
ORACLE_HOME=/opt/instantclient_10_2
export ORACLE_HOME
PATH=$PATH:$ORACLE_HOME
export PATH
TNS_ADMIN=/opt/instantclient_10_2
export TNS_ADMIN

export PATH
CLASSPATH=/opt/instantclient_10_2:/opt/instantclient_10_2/ojdbc.jar
export CLASSPATH

As i have downloaded the Sqlplus utility as well, i am able to connect to the Oracle FARM via sqlplus.
On the other hand, i am unable to connect to the same database via the application. It constantly gives me the following exception,

I have used the classes12.jar and ojdbc.jar which came with the download and nothing seems to work. A bit surprising when sqlplus works and not the application. I suspect there could be an issue with the driver class. I have been struggling to figure this out for days now...
Can anyone please share their thoughts if something similar was observed earlier please.
Any quick help will highly be appreciated.

ORACLE_HOME=/opt/instantclient_10_2
export ORACLE_HOMEYou don't set ORACLE_HOME with Instant Client.
PATH=$PATH:$LD_LIBRARY_PATH
export PATHThis is unnecessary.
CLASSPATH=/opt/instantclient_10_2:/opt/instantclient_10_2/ojdbc.jar
export CLASSPATHThis is wrong.
It should be:
CLASSPATH=/opt/instantclient_10_2/ojdbc14.jar:<whatever else you need there>
Java.library.path=/opt/instantclient_10_2
export Java.library.pathThis is useless; java.library.path is not an environment variable.
java.lang.UnsatisfiedLinkError: no ocijdbc10 in java.library.pathThe case is pretty clear. You want to use the OCI driver (your URL starts with "jdbc:oracle:oci:"), so the Java Virtual Machine is looking for libocijdbc10.so in the Java library path but cannot find it.
What is also clear is that the program does not use the CLASSPATH environment variable you set, because then it would never have found the Oracle Driver.
So it seems that your program is ignoring the environment you set (which would explain why it also ignores LD_LIBRARY_PATH which you set correctly).
You must have the environment variables set and exported in the shell that starts the "java" executable.
Also, check that there is no other ojdbc14.jar on this machine (use "find").
To help you debug your problem, let me explain how Sun Java sets Java library path on Linux:
- If you start java with "java -Djava.library.path=/some/dir:/other/dir ...", the Java library path is set to exactly that value.
- If you do not specify -Djava.library.path, the Java library path is taken from the environment variable LD_LIBRARY_PATH.
- Directories listed in /etc/ld.so.conf have no influence on the Java library path (which gave me quite a headache in the beginning).
Do you really need the OCI Driver? If you can do with the Thin Driver (i.e., use an URL that starts with "jdbc:oracle:thin:") you don't need any shared libraries at all.

Unable to connect to Oracle 8i using the JDBC - OCI8

I am unable to connect to the to the Oracle 8i database using
JDBC 8.1.5. er. Each time I try I get the message:
"java.lang.UnsatisfiedLinkError: no ocijdbc8 in
java.library.path"
When I try to establich a "connection" using the connection
manager with JDeveloper 2.0 I get the message:
"No ocijdbc8 in shared library path"
What's the problem? Is it that I do not have the appropriate
driver? It is unlikely because the thin driver works...
null

I dealt with this problem. For some reason OCI drivers
installation is not included in typiclal Jdev 2.0 instalation.
(bug?). In your instalation kit find Oracle 8i instalation disk,
and run the installer on the client machine (i.e. the same
machine where Jdev is installed where you were not able to
connect with OCI-8). Choose client installation and choose
custom installation. Than in the product list choose JDBC
drivers. Make sure OCI drivers are included. Install it. Now you
can find file ocijdbc8.dll in your ORACLE_HOME/bin directory.
Now you should be able to connect using OCI-8.
Best of luck,

Unable to connect to the specified database

I am evaluating the Oracle Report Builder and I am trying to connect to a Sybase database using ODBC.
I have successfully made a connection with the Query Builder but have not been able to connect with Report Builder.
I get the following error:
REP-0501 unable to connect to the specified database
ORA:00021:invalid session id: access denied.
Any help on this as to what I need to connect to a sybase database would be most appreciated

I checked the sqlnet.ora on the server ,its not contain any thing like that:it just contain:
# sqlnet.ora Network Configuration File: C:\Ora10iAS\network\admin\sqlnet.ora
# Generated by Oracle configuration tools.
SQLNET.AUTHENTICATION_SERVICES= (NTS)
NAMES.DIRECTORY_PATH= (TNSNAMES, HOSTNAME, LDAP, EZCONNECT, ONAMES)
so ,what to do ,what to add here??please the problem come back again ,all the offices are ok except that office and they format the machine and change every thing but it stil cant run the report.
Best Regards
