• Is there a way we can configure the oracle database to accept connections from particular type. For example, we may limit Server Oracle don't not to accept applications for connection to the JDBC thin driver?

  I have an oracle server which is our recovery server disaster. When I switch my application of the primary site to secondary site, we have a window of downtime during which it must implement the secondary site. When setting up the application on the secondary site, I am getting below error please take note that primary and secondary are always synchronized. The application uses the thin driver JDBC to connect to the database.

  java.sql.SQLException: ORA-01017: invalid username/password; logon denied

  
  

  However when I use the same user name and password to connect to the SQLPLUS it connects successfully. When I use the sqldeveloper or any other jdbc connection, it fails with the above error.
  

  
  

  Can someone please advice what may be the setting on the oracle server that limits connections jdbc or any setting related to jdbc on the oracle client

  For others this has been resolved with

  This is the setting in sqlnet.ora

  SQLNET. ALLOWED_LOGON_VERSION = 12

  later, commenting on the above setting and restart the listener. It worked.

  Thanks for all the answers

• Install Oracle 64-BIT ODBC connection with vCenter 5.0 question

  I'm running W2K8R2 64 bit and I am trying to connect to an ORACLE DB so I can install vCenter 5.0. I had the Oracle DBA create the DB, then I went into my ODBC on my server vCenter. I tried to create a system DSN and noticed that it there was only the SQL client. No problem, I went ahead and installed the 32 bit ODBC Oracle client\driver.     I went back, but he has not yet shown, after more research, I LEARNED that I had to go to C:\WINDOWS\SYSWOW64 and appear ODBC32. EXE that I did and I was able to connect to the DBs and see my TNS name and test connections with success. I then in vCenter 5.0 installation, but when I got the option to choose between SQL Express and the DSN names, I couldn't see my DB in the fall down... What don't get me?  I'm using using SQL, but the process is OK except that I do not see the DBs when the installation menu of vCenter dropdown, even though I was able to connect successfully to them through ODBC. ??

  In order to get listed in vCenter Server Setup, you must have created a 64-bit DSN, which requires a 64-bit Oracle Client. You can try to create a 64-bit DSN after you install the full client for 64 bit / instant client

  Hi aman

  first of all, I didn't understand anything to the summary doc link
  Maybe because I'm beginner in oracle.
  I force uderstand where to configure them for isql * plus DBA access

  I'll suggest that you read a little more carefully this document because there is complete steps are given to set access s/n. scroll down a bit and you'd see these steps.

  I have uninstall the 10g and re - install the 11 g r2 that is compatible with my OS win7 64
  and now, the Business Manager works but I am unable to connect
  http://host_name:port_no / isqlplus

• Instant Client connection problem - Excel 2007 for Oracle 10 g

  Dear users,
  
  I want help to connect Excel to Oracle.
  I use Excel 2007 (32-bit) on Windows Vista Enterprise 64-bit. I want to connect to a database 10g to Oracle through our local network using ODBC. I need to retrieve data once in an excel sheet.
  There is no firewall or connection between my current computer problems, problems as I can connect to my machine, using SQL developer as a local client to the Oracle database that is located on another machine on the network.
  I tried to make an ODBC connection, but Oracle is not listed as a driver.
  In my view, what ODBC is the best way to do it, but please correct me if I'm wrong.
  
  It is an Oracle 10 G database.
  I downloaded instantclient-basiclite - 64 - 11.2.0.2.0.zip a windows.x
  I also downloaded the additional ODBC components: * Instant Client Package - ODBC: extra to allow ODBC applications libraries.
  
  I unzipped in a folder called C:\instantclient_11_2
  The system path include one. I checked after reboot.
  I placed my tnsnames.ora (that I copied from the server) in this folder.
  I got it from the server: D:\Oracle\Ora10gR2DB\network\admin\tnsnames.ora
  
  I ran the exe "odbc_install" and he told me that the ODBC has been successfully intalled.
  
  When I went to the Control Panel, administrative tools, ODBC
  
  On the user dsn tab
  
  I added a new entry. I chose the Oracle driver (previously it was not in the list)
  
  Use the following values
  
  Data Source name: OracleL
  123 description
  The TNS Service name: I chose for my prod environment drop-down list. (There are two entrances with the name of the production, one uppercase and one lowercase)
  
  
  UserID: my user name
  
  I tried the connection Test and got this:
  
  Unable to connect
  
  SQlState = S1000
  [Oracle] [ODBC] [Ora] ORA-12545: Connect failed because target host or object does not exist
  
  
  Any suggestions please.
  
  Thnaks in advance.

  If Excel is 32-bit (2007a) and the Oracle client libraries are 64-bit, it will not work. needs 32-bit 32-bit.
  You should probably remove current ic packages and get the 32-bit instead.
  Start over.

  On Windows x 64, to run the 32 - bit ODBC DSN/drivers, we need run the Windows\SysWoW64\odbcad32.exe tool.

  There might be a possibility that the listener is losing the database service, please check the listener services, the database is registered with the listener. Try to set the local_listener and remote_listener parameters. To connect to the RAC database to create a Service for the database in DBCA.

  Surely, this will solve your problem.

• How to enable detailed connection tracing ODI Studio? and how do I resolve a connection problem.

  Is it possible to get a detailed trace of connection attempts from the studio of ODI on my deposit work?

  I tried to enable tracing in changeant...\oracledi\client\odi\bin\ODI-logging-config.xml according to the instructions that I found here: http://haithanh8x.blogspot.com/2013/03/ODI-11g-agent-logging-tracing.html

  The studio.log file has been created, but it is empty.

  I use studio ODI and basically I want to troubleshoot why I can't connect to the repository. When I try the Test button, I get an error "Invalid repository connection", here is the error that is displayed under Details:

  oracle.odi.core.config.WorkRepositoryResourceFailureException: ODI-10182: Uncategorized exception for access to the repository.

  Could not make JDBC connection; nested exception is java.sql.SQLException: Exception occurred while getting connection: oracle.ucp.UniversalConnectionPoolException: cannot get data source connection: java.sql.SQLRecoverableException: IO error: the network adapter could not establish the connection

  at oracle.odi.core.repository.Repository.getWorkRepository(Repository.java:195)

  at oracle.odi.core.OdiInstance.createWorkRepository(OdiInstance.java:531)

  .........

  .....

  ..

  Other important details:

  1.-s' Please note that before I use the Test button under the repository login Panel, I'm able to choose my work deposit that was recovered in the receiving of work section using the magnifying glass.

  2 - I am able to connect to the database with SQLDeveloper using JDBC, in fact I can connect with exactly the same connection string that I use in ODI, also I have no problems connecting to the database using SQLPlus.

  3. - this repository database is on a cluster and as mentioned, I have no problems to connect to it with other tools. Don't know if being in a cluster makes a difference (I tried hostname, scan name and the names of vip to connect)

  4 - this database is running in another server, and I have had no problems connecting to the front. In fact, I restore to a different server no CARS and was able to use ODI. (maybe something in the new RAC server that does not allow the connection?)

  I would like to get a path to better understand what is happening while the Studio tried to connect to the repository. It seems to me it is able to read the name of the repository work so I don't understand why there are connection problems later.

  Question: is it the fact that I am able to read the repository name means JDBC work? (Please confirm)

  I'm running out of ideas on what to try, so your help is appreciated.

  Thank you!

  Answer the questions:

  1-to get a detailed trace

  One option is to use a thick connection instead of a thin. This requires the installation of customer Oranet and settings but allows you to trace the SQL in the side server. That will let you know what the problem is.

  2. to turn on tracing

  Under search support Oracle Oracle Data integrator, there is an information center that includes detailed instructions and examples (files) on how to configure tracing.

  3 - If the test button works and pulls the name of the repository work means that the connection works, unfortunately, is not sufficient because ODI does not use the connection string supplied to connect to the repository instead, it uses the language sql stored in the repository and uses SQL to connect, so location you will see two connections for the initial attraction of the repository data, and then the other link with the chain withdrew from the database. In this case, the problem was that the database of repository has been migrated to another server, the previous server that the connection was made with localhost, but it does not work on the current server, because it runs on CARS, so outside the ODI, I updated the SQL used to connect with the SCAN name instead , and I was able to connect. The SQL is illustrated in the trace obtained using a thick client.

• The most convenient airport and Arris CM820 modem drop connection

  I have Airport Extreme 6 Gen and a few months back from a 'new' Arris CM820 Time Warner Cable modem. Since then, I did have slowly and dropped connection problems a day - mostly in the evening so that streaming on Apple TV and Roku, and navigation devices on the MacBook Air and iPads at the same time. Each time, I do unplug it, wait 30 seconds and plug back in and it's good for a while. But it happens almost every day. I have been emailing and talking by phone with a representative from Apple support for a few weeks (had a record of the case), then she disappeared on me. I've updated firmware (v 7.7.7). Have also tried using a 5 G network as an alternative - but there is no help. Anyone else having these issues with the 'new' modems THAT TWC sends?

  If you have already tested the modem, try to choose a time when you can turn off the AirPort router and connect your Mac directly to the modem for a day or two to try things like that.

  Alternatively, you can of course call TWC support and have them check the line and the modem, but you already know that they will say that "things seem good to here" and that "the problem must be another device, like your router. .. even though things worked very well before receiving the 'new' modem.

  If the MacBook Air listed in your slogan is the only Mac you have, then you will need a lightning Apple Ethernet adapter to perform this test.   Maid in Gigabit Ethernet Adapter - Apple

  If connection problems continue when you have the Mac connected directly to the modem, the modem would then become a strong suspect.  This is possible.  But, it is also possible that the connection remains stable throughout your test... and if it's the result, TWC has strong arguments to say that their service and the modem are working well.

  Until then, you really don't know if you have a modem problem, a problem of the airport, or as can sometimes be the case... a modem - router compatibility issue. In such cases, the modem out OK and airport does as well, and each manufacturer blames the other for the problem.

  Please post on your 'test' results in the next few days.

• Tried all your suggestions and always receive "Unable to connect" when using ANY search engine.

  Can't use any search engine of FF 40.0.3 on Macbook Pro model with 10.8.5 OS 9.2. Receive "Unable to connect" message when you try to use a search engine. Other than the search engine and Mozilla Web sites to connect properly. 40.0.3 on another Mac FireFox works fine without any problems.

  In addition, I can not access the FF "Get modules" page or the home page of Mozilla. Search engines will connect not their home page or the search bar. Problem just started. I had previously been upgrade and have resorted, FF 40.0.3 without problem when it was issued. Solutions of attempts included refresh FF, launch FF in safe mode, run with all plugins disabled, graphics hardware acceleration disabled. None of these fixed the issue.

  Had already tried your suggestions, without success, but has once again to be sure. Without success. However, I made a further exploration of my own and found out that IPv6 is set to "Link Local" only in my router. I have reset on 'Automatic', the router reset to update, and my problem was solved. So it was the IPv6 setting (unlikely) or the router reset (probably) that solved the problem, or it is your suggestions I tried and did not work, COMBINED with the router reset which solved the problem (quite possible).

  Thanks for the comments!

• AirDrop does not and the bluetooth does not connect to the macbook pro

  Hi, I have an iphone6s and a macbook pro, release used to work before, but now it is not. I think it's probably because I can not connect my macbook on my iphone via bluetooth which is something that probably dump uses.
  Does anyone have any suggestions? He used to work before.

  My iphone 6s is 9.3.2.

  My macbook is on 10.11.5 (15F34).

  I tried to restart my mac and reset my Iphone. I also tried to delete the file com.apple.bluetooth.plist.

  I also tried to disable the bluetooth and turn back on for both devices.

  My airdrop is already set to "everyone".

  Sometimes, it is not even discover my mac on my iphone even if I discover my iphone on my mac. When I try to pair, this is for me the pair prompt on my iphone and I click and it goes to 'Connected' and then back to "not connected".

  And that's fine if I can't connect my iphone to my mac via bluetooth, I want just the parachuting of work.
