Proxy user when connecting using ODBC
Oracle 11gR1 RHEL 5 46 bit
Hi all,
I have a developer that successfully connects to PowerDesigner using an ODBC connection. However, when he tries the connection as a proxy user, it fails. Is it even possible to connect using the proxy method?
jim/jimpasswd - succeeds
jim[OE]/jimpasswd - fails
Thanks all.
Yes, see the below links
http://www.oracle.com/technology/products/ias/toplink/doc/1013/main/_html/dblgcfg008.htm

Hope this helps.
Regards

Hi , I am using crystal report XI R2 in visual studio 2005 . Backend is sql server 2000. I have made a connection with odbc connectivity and using dsn. I am using a stored procedure as datasource of report. It is working fine all the database fields are available. Now when i try to connect with the ado connection having same stored procedure as datasource of report , I am not getting data fields. I dont know where is the problem in my stored procedure or in report. But when i connect through system dsn using odbc connectivity everything is working fine. A MAP filed dialogue box appears when i try to change the datasource location to ado from odbc.There is a barely acknowledged issue. For Mac users Apple has released an update to the app, but for iOS users the recommendation is for users to update their ipad to the most recent operating system.
There may be a fix coming for iOS6 users (which seem to be many of those having problems) or there may not be. If your ipad isn't up to date then you can update it and see if that helps, or if you don't want to update then you may want to wait and see if there is either a fix or if it fixes itself. -
Hi all,
I have problem to connect on my XE database using ODBC-front end msaccess2003.In local network all work fine but when i try to connect via static ip adress using ODBC problem starts.I wont to connect client who use access application, with my database from remote place.Cliant has instoled oracleclientXE, tnsnames is on bin dir, on odbc i put 82.208.201.51/xe for TNS Service Name and it wont work? What is the problem?1) "It won't work" is not particularly descriptive. Is there an error? If so, what error are you getting? If not, can you describe the behavior you're seeing?
2) Are you sure that nothing is blocking access to port 1521 (or whatever port your listener is running on) from the remote network segment? Most firewalls, for example, would block this port by default.
3) What operating system is your database using? If you are on Windows, by default, connections on port 1521 will be redirected to one of a large range of ports that could be blocked if there is any sort of firewall in place.
4) Can the client ping your IP address?

ORA 2005 error when you using ODBC driver of 10.2.0.3
I am getting following error when connecting Oracle 10.2.0.3 to Oracle 11.1 database from a thrid part application:
Issue Description. An application using Oracle ODBC driver version 10.2.0.3 to communicate with the Oracle database 11g tries to update the field “SOURCE_CODE” of LONG data type in table “SUBROUTINE” returns the following error.
ORA-02005: Implict -1 length not valid for the bind or dfeine datatype.
I updated my client to 10.2.0.4,, error is still present. Does any one know what patch to install to get rid of this error. I cannot modify the third party code.What are the system requirements (supported config) of 3rd party app?
According to the 9.2 Error Messages document,
>
ORA-02005 implicit (-1) length not valid for this bind or define datatype
Cause: A negative length for the define variable was passed to a define function.
Action: An explicit, non-negative, length parameter must be passed.
>
Perhaps you should report this back to vendor as a bug.
You could also turn on odbc tracing (driver/dsn config) to catch the cuplrit statement. -
Wheh to use abap proxy and when to use idoc
Hi All,
Please provide some clarifications for the below points :
What is Sproxy?
2. Why we are using Sproxy instead of Idocs
3. When we are going Proxy ?
4. What are the types of proxy ?
5. How to Create to Proxy ?
6. What the Difference between SProxy and Idocs
7. What is SOAP file? When we are using SOAP file ?
Thank you.
Regards,
BharatHi Bharat,
You seem to have a range of Questions. I will try and answer as many as possible.
What is Sproxy?
SPROXY is a transaction [T-Code] on the SAP ECC/CRM etc side where you can see the objects designed in SAP PI ESR and develop its corresponding ABAP code. SPROXY T-Code displays the Service Interface. You can read more about it in the following site:
**************** - XI - ABAP Proxy communication
2. Why we are using Sproxy instead of Idocs
For Certain implementations Standard IDocs may not be available and it is quite tedious to create a Z- IDoC and therefore it is advantageous to use Proxy. You can read more about this doubt in the following links:
Choosing to use IDOC standard or ABAP Proxy?
IDOC vs Proxy
ABAP Proxy Vs IDOC
3. When we are going Proxy ?
When there are no Standard IDocs available. Please refer above links to get an answer for this.
4. What are the types of proxy ?
5. How to Create to Proxy ?
Again the following link has the answers for both these questions:
**************** - XI - ABAP Proxy communication
6. What the Difference between SProxy and Idocs
Difference is in the way the communication happens. Standard Idocs are already provided and you can use them directly while Proxy you will require to write the code on ECC side. You can refer the following link to understand more:
Advantage of ABAP proxy over BAPI
7. What is SOAP file? When we are using SOAP file ?
I have not heard of anything called SOAP file. SOAP is a protocol used for communication and you can send files as attachment in your SOAP to Any(file/idoc/Soap etc) or vice Versa Interfaces. Infact Proxy itself is SOAP based communication with XI 3.0 Protocol.
Please explore SCN to know more about the various scenarios. There are endless possibilities in SAP PI.
Hope this Helps.
Thanks & Regards,

MS Access .mdb connection using ODBC could not resolve the connect identifier ORA-12154
Dear All,
I'm trying to use MS Access .mdb file as source to my OWB application. I need to connect to the ms access .mdb file first using odbc. Here are the step I do:
1. Define ODBC connectifity
control panel -> admin tools -> data sources -> System DSN -> Add
Choose Microsoft Access Driver (*.mdb) -> Finish
Data source name: msaccess -> Database: Select -> .mdb file location (C:\MSAccess\att2000..mdb)
2. Configure Listener
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = CLRExtProc)
(ORACLE_HOME = C:\app\Administrator\product\11.2.0\dbhome_1)

(SID_NAME = msaccess
(ORACLE_HOME = C:\app\Administrator\product\11.2.0\dbhome_1)
(PROGRAM = hsodbc)
ADR_BASE_LISTENER = C:\app\Administrator
3. Configure Oracle HS
File name initmsaccess.ora
# HS init parameters
HS_FDS_CONNECT_INFO = msaccess
HS_FDS_TRACE_LEVEL = 1
# Environment variables required for the non-Oracle system
#set <envvar>=<value>
4. Edit tnsnames.ora
msaccess=
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
(CONNECT_DATA =
(SID=msaccess)
(SERVICE_NAME=msaccess)
(HS=OK)
5. create database link
create database link msaccess using 'msaccess';
6. Run a query to test connection
SQL> select * from departments@msaccess;
ERROR at line 1:

Freeze/Hang when connecting using SSLSocket
Hi
I have a client/server connection using a SSLSocket. The SSL stuff is using a certificate inside a keystore with a public key which is stored in a signed .jar file, as part of the set of jars obtained by the client using Java Web Start (jars are signed, of course).
In the server side I have estabished the javax.net.ssl.keyStore and javax.net.ssl.keyStorePassword properties with the right values, and are pointing to the keystore where I have the private key wired to the public key inside the certificate stored in the client's keystore. This way I can use the default SSLServerSocketFactory to get a SSLServerSocket (and then SSLSockets from the ssocket.accept() method).
In the client side I do this:
char[] passwordKeystore = "keyForTheKeystore".toCharArray();
KeyStore ks = KeyStore.getInstance("JKS");
ks.load(CommManager.class.getResourceAsStream("/path/to/the/keystore/inside/the/jar/file"), passwordKeystore);
TrustManagerFactory trustManagerFactory = TrustManagerFactory.getInstance("PKIX");
trustManagerFactory.init(ks);
KeyManagerFactory keyManagerFactory = KeyManagerFactory.getInstance(KeyManagerFactory.getDefaultAlgorithm());
keyManagerFactory.init(ks, passwordKeystore);
SSLContext sslContext = SSLContext.getInstance("TLSv1");
sslContext.init(keyManagerFactory.getKeyManagers(), trustManagerFactory.getTrustManagers(), new SecureRandom());
SSLContext.setDefault(sslContext);
sslSocketFactory = sslContext.getSocketFactory();I'm exchanging data exchanging serialized Objects through this SSLSocket. I've tried to "startHandshake()" in the client right after "connect()" (also in the server with the SSLSocket I get from "ssocket.accept()"), before getting the reference to the streams, but I've also tried to skip this step. Then I get first the ObjectOutputStream and then the ObjectInputStream in both sides.
Here is the problem:
This code works fine in a computer, but in another (both Linux, only different versions of Ubuntu, and always using the oracle JVM; this happens with both java6 and java7) there is a strange delay when I try to get the ObjectOutputStream, and I tried to exchange the order (first OOS in one side and OIS in the other, just to test) but the problem is still there. After 25/30 seconds the connection is finally established and everything works.
By enabling debug in the java.net stack (I don't remember the exact name of the property) I've seen both VM's loading the known certificates, but everything is paused when it's going to obtain the reference to the streams, and finally works after this 25/30 seconds delay (I can see the helloClient and helloServer steps, and the algorithm negotiation).
What might be going on here? Is it really using the certificate I created (self-signed), or this delay is related with some timeout because of not being using the proper key pair, which finally forces the connection to use a default key pair provided by the server, as long as client autenthication is not required?
Regards

Hi experts,
Please could you answer me the next questions:
- Can we merge information from 2/3 queries/systems in Crystal using ODBC connection?
- Can we aggregate or manipulate information in Crystal using ODBC connection?
Many thanks in advance for your answer.
Judith.- Can we merge information from 2/3 queries/systems in Crystal using ODBC connection?
Yes. Performance depends on the number of rows you fetch from each ODBC connection. If you want to merge a large number of data you may consider building a DWH and load your data in there.
- Can we aggregate or manipulate information in Crystal using ODBC connection?
Yes. Crystal Reports' report engine will allow you to process data. Still if you want to work on a very large ammount of data it is advisablke to review your data model and do as much processing as possible on the data source.

Odd things here ---
Both the dbo.MSP_EpmProject_UserView and the MSP_EpmProject tables, are missing a number of fields including: ProjectName; ProjectAuthorName; ProjectManagerName, etc. Looked in the schema to make sure I wasn't crazy, and they are listed there
just like in 2007.
Using Project Server 2013 (on-prem) and Access 2013.
Suggestions?Hello,
I've not tried from Access before so cant comment on that but I assume if you connect using Excel 2013 the data and columns are correct?

Error when connecting via ODBC connections
Alright, so....
I have a Windows 7, 64 bit OS. I installed Oracle 10g, I installed Crystal Reports Xi release 2.
Via ODBC Administrator, I set up my data sources, and they all connect successfully.
I go into Crystal Reports, create a new report, and attempt to set a new connect and use those same data sources. I get prompted for my user name and password. I get the error:
Logon failed.
Details: IM004:[Microsoft][ODBC Driver Manager] Driver's SQLAllocHandel on SQL_HANDEL_ENV failed
HELP! I've changed security settings, I've wiped my machine and started over from scratch, I've even installed Oracle 11g. Please help! I'm about to pull my hair out. I am sure this is probably something easy or something I've overlooked, but I give up and throw the towel in.Go into \windows\syswow64 and use the odbcadm32.exe located in there. It's the 32 bit version of the ODBC Administrator.
Also, search before posting and this has been answered.
And you need Service Pack 6 to be supported on Windows 7.
Thank you

Hi,
It's possible to connect to database with de driver ODBC?.
I know the adapter JDBC but i don't know if exist an adapter ODBC.

OS_USER not correct when connecting using JDBC Thin Client on 10G
Hi Folks,
We are migrating an application from a 9i database to 10g and have a problem that someone might have come across before.
The application is a Java applet based application that connects to the database using JDBC Thin client. on 9i the OS_USER comes up as the user running the applet but in 10G it is coming up as the user account that installed 10G on the DB server.
We tried using a 9i client to identify if it was a client or DB issue but its the same problem with the 9i client connecting to the 10G DB.
If anyone can help it would be much appreciated.
Thanks,
John.What is the return of this command?
SELECT sys_context ('USERENV', 'OS_USER') FROM dual;
Is it the DB user or the OS user? -
Can't log in to local user when connected to server
We used to have 3 local accounts on each of our machines: 2 required a password, and 1 did not.
Then we hooked up our server and students have been logging into it. We haven't really touched the local accounts since then. Now I need to get access to the local account with no password. I can access it only if I disconnect the machines from the network, but I can't get into it otherwise. I have tried giving the account a password, but it still won't work once I hook back up to the network.
How can I get access to this account without having to disconnect every time? The other 2 local accounts work with no problem.
Thanks for any insight!
NancyYou can use SS management studio to connect to DB. What you need to do, is to ensure your connection string is something like
<connectionStrings>

160n halt when connected using this method
hi there,
I have the following scenario which cause router 160n to be down
I have a 160n linksys router which is used as dsl router and directly connected to the internet, and I have another linksys router 160n which is connected to the first 160n router "DSL Router", and linux server (Squid & dhcp) which is also connected directly to the first 160n router " DSL router",
the problem accurs when I turn my linux srever on, the DSL router start flashing its lights and stop working until I disconnect my server and restart the router.
I wonder if anybody can help,
thanks with best regardsMake sure you have different IP for both routers and they are cascaded correctly. Search the Linksys web site on how to cascade two routers correctly.
