  Is it possible that muse adobe to have a Back-End that connects to a database using MySQL, SQL, Access etc...

  Nothing to do with the Muse at all. You have things backwards. If you use a dynamic interface, you work in the API hooks and predefined functions and that he don't just slap on an arbitrary HTML façade. It is simply not how it works.

  IMO, it's a security risk to allow the connection AS SYSDBA through the network & I never turn on any DB.

• How can I connect to my database externally from another pc on the network?

  Hi all

  I just install 12 c on my Oracle Linux box and I am able to connect locally to the database, as intended. Now, what would be the first step to connect to my external database from another computer on the network. By example, if the database server is 10.0.0.150 and I want to connect to 10.0.0.151 how can I make this happen? If necessary here are a few references:

  Hello EdStevens,

  I tried to use the SID with SID = anthonydb and I got the same error message. I believe that we must resolve before listener troubleshoot us this error...  If we look at the file of the listener:

  I have two entries, and I think that I should remove the last entry:

• The network card does not connect to the remote server

  My desktop computer has been recently updated to Windows 7 64 bit so I had to reinstall everything. Part of my job includes pulling data from two separate databases on a remote Oracle server. Previously with Windows 32 - bit Oracle SQL Developer worked after that I installed the Oracle Client and configured using Net Manager AMT settings. However now in SQL Developer, I get the following error message when you try to connect to databases using the same exact AMT settings.
  
  Error: "status: failed Test failed: the network adapter could not establish the connection.
  
  Versions:
  Windows 7 64 bit
  Oracle SQL Developer 3.2.2 (64-bit)
  Update to Java SE DK 6 43 (64-bit)
  Customer of Oracle 11 g R2 (64-bit)
  
  I've set up two databases under Naming Service in Oracle Net Manager. I used screenshots of my previous Net Manager settings to create the connections if everything is correct. Also, the two couplings to test successfully in the Net Manager. Contains the tnsnames.ora file
  
  PROD =
  (DESCRIPTION =
  (ADDRESS_LIST =

  )
  (CONNECT_DATA =

  )
  )
  
  
  In SQL Developer, I adapted the new connection settings exactly as before with a different screenshot of my connections to the previous developer. For example, I selected 'TNS' of the connection Type and selected "DWHOUSE" for network Alias. I even tried to put the chain of connection such as the login, but everything I've tried has made the mistake of connection.
  
  I followed some of the suggestions in other threads, but everything seemed to work, as I was able to connect to two databases using SQL more. Also, 'tnsping prod' both 'tnsping dwhouse' resulted in an OK. Same ODBC using the Oracle driver works to connect to these databases.
  
  I thought installing the JDK, Oracle Client, and SQL Developer as well as my screenshots would be an easy process and without hassle to connect to these databases. I'm doing something wrong? What else can I try?

  Of course, the point marking in your recent post concerns the former developer SQL install connection very well during execution by the G-drive.

  Although I'm not sure of the exact rules, I noticed that when the Oracle client resides on drive C, but the SQL Developer install is elsewhere, captures some files in its installation rather than from the Oracle SQL Developer client directory. An example is the ojdbc6.jar file. So you could also try installing SQL Developer 3.2 on another drive (internal or external non-disque C) and see if it works.

• Connect to the Oracle database fails when you use Microsoft ODBC or OLE DB Driver

  There was a problem when you apply the KB3126587 hotfix where connections to an Oracle database using the Microsoft ODBC driver fails if run from automated processes. Running the same process manually would succeed. The update issued KB3147071 solved the problem successfully.

  Yesterday, several patched have been applied and the problem came back. The patches are: KB2862152, KB2868626, KB3163244, KB3168965, KB3170455, KB3163251.

  I saw yet no acknowledgement or difficulty of Microsoft. I prefer not to uninstall security patches, but it is a problem of production.

  Any ideas what specific patch maybe breaking it again?

• Connection to the database to Oracle using Oracle Apex 5.0.1

  Hi all

  Is it possible to connect to the Oracle (Oracle SQL Developer 4.1.1) database using Oracle Apex 5.0.1 instead of using the object browser. As he was more workspace after you have downloaded the data we have on CSV Excel.

  For example: regardless of the tables I've created in the Application Builder is created in the object browser. We have limited the workspace of 500 MB. This is the reason why we cannot use this method to load the data and retrieve it. (Note: can I ask 2 GB of space to work on the approval of the Director, who is still not sufficient)

  Is it possible that I will create an apex.oracle.com application by using the application builder and I will create in the database tables. When I load the file in application, data will be stored in the database Oracle instead of the object browser.

  Well let me know is possible, if yes, how can I proceed.

  If this isn't the case, please let me know how I can get more workspace.

  According to my understanding, other possibilities are: 1) taking backup of old files and free up space, 2) create another workspace and get extra work space.

  Thanks for your help!

  Kind regards

  Vinod

  Hello

  When you load data using APEX SQL Workshop utilities for example, the data is stored in your database tables.

  Object browser is just seen tool your schema as the table objects and the data in the tables, just as SQL Developer.

  If you have no good reason to keep these files that you downloaded in the workspace, delete those. Data is stored in database tables.

  Kind regards

• Connect to the database with SQL * more: is TNSNAMES. ORA used?

  Hello

  We have a local database called DEV01 and a copy of this database in a data center. To be able to connect to both databases, the TNSNAMES file. ORA

  on the local database server (not the one in the data center) has the following entries:

  / * Entry for the local database * /.

  DEV01_local, DEV01_local. WORLD =
  (DESCRIPTION =
  (ADDRESS_LIST =
  (ADDRESS = (PROTOCOL = TCP)(HOST = server01) (PORT = 1521))
  )
  (CONNECT_DATA =
  (SERVER = DEDICATED)
  (SID = DEV01)
  )
  )

  / * Entry for the database in the data center * /.

  DEV01, DEV01. WORLD =
  (DESCRIPTION =
  (ADDRESS_LIST =
  (ADDRESS = (PROTOCOL = TCP)(HOST = server02) (PORT = 1521))
  )
  (CONNECT_DATA =
  (SERVER = DEDICATED)
  (SID = DEV01)
  )
  )

  When I connect to the local database server, I set the Oracle environment as follows:

  export ORACLE_SID = DEV01

  export PATH=/opt/oracle/app/oracle/product/9.2.0/bin:$PATH

  export ORACLE_HOME=/opt/oracle/app/oracle/product/9.2.0

  Now I start SQL * more as follows:

  Oracle # > sqlplus user/user

  SQL > select instance_name, host_name from v$ instance;

  INSTANCE_NAME HOST_NAME

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

  SERVER01 DEV01

  As the SID is on two databases of the same (DEV01) I really don't understand how Oracle decides which of the SQL databases * more connects to.

  Is it the entry in the TNSNAMES file. ORA?

  But when I start SQL * more as follows:

  Oracle # > sqlplus user/user@DEV01_local

  SQL > select instance_name, host_name from v$ instance;

  INSTANCE_NAME HOST_NAME

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

  SERVER01 DEV01

  or

  Oracle # > sqlplus user/user@DEV01

  SQL > select instance_name, host_name from v$ instance;

  INSTANCE_NAME HOST_NAME

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

  DEV01 server02

  everything is as expected.

  Does anyone know who is the chosen database when just to connect with 'sqlplus user/user' (without the @DEV01 or @DEV01_local)?

  Any help will be appreciated!

  Rgds

  Jan

  When you connect to the local database that is connected to the server01, you need only specify the sid in the environment, in this case, Oracle tnsnames file to connect, actually uses, it uses any of the listener.  It uses what is called a connection needed.  It is purely a side connection server, and as long as the sid is located in the environment resolves to a database running on that server, you will be get connected.

  When you connect using the @connect_descriptor, like you second case, then Oracle will use the configured naming, including tnsnames, methods to solve the 'real' database  In this case, the auditor is required to create the connection to the database.

• Connection to the remote database using Oracle 11 g Builder

  Hi all
  
  This could me stupid question, but I have installed Oracle Forms and reports 11g on Win 7 machine. I copied the file "tnsnames.ora' on the record ' ORACLE_HOME/Network/Admin". We use Oracle EBS R12 and I want to create a new report using 11 g.
  
  Using the report wizard after providing a simple query, we need to connect to the database. And even after the entry of TNS, I am getting error connecting to the database, following
  "REP-0501: the specified database can be connected.
  "ORA-12154: TNS: could not resolve the connect identifier specified.
  
  I am able to connect to the same database using the Report Builder (10.1.2.0). Is there another place where I need to set the TNS entry? How can I solve this error? Please guide...
  
  Kind regards
  Priyanka

  Hello

  In forms and reports 11g, default defined in tnsnames.ora is: ORACLE_INSTANCE\config.
  Please note that the ORACLE_INSTANCE is not the same as ORACLE_HOME.
  Example:
  ORACLE_HOME = D:\Oracle\Middleware\as_1
  ORACLE_INSTANCE = D:\Oracle\Middleware\instances\asinst_1

  If you set the admin TNS_ADMIN variable in the registry, you can point to a new location for tnsnames.ora

• not able to connect to the database using the oracle instant client

  There is little that tnsping can do sqlplus can't.

  Instead of
  tnsping mydb.myorg.com
  Try
  sqlplus-s-L /@mydb.myorg.com
  or
  sqlplus-s-L user/[email protected]

  If you get
  ORA-12154: TNS: could not resolve the connect identifier specified
  you know that the customer could not resolve 'mydb.myorg.com '.

  If you get
  ORA-12541: TNS:no listener
  then "mydb.myorg.com" could be resolved, but there is no listener it running.

  If you get
  ORA-12514: TNS:listener is not currently of service requested in connect descriptor
  then "mydb.myorg.com" could be solved, the listener is in place, and the database is out of service.

  If you get
  ORA-01017: name of user and password invalid. connection refused
  you know that 'mydb.myorg.com' has been successfully resolved, and the database is running.

  If you want more details, such as how and what "mydb.myorg.com" is resolved, turn the tracking by adding the following to "sqlnet.ora:
  TRACE_LEVEL_CLIENT = ADMIN
  TRACE_DIRECTORY_CLIENT = C:\TEMP (a writable directory)

  Then you will find lines like this in the trace file:

  -THE INFORMATION SOURCE PARAMETER FOLLOWS-
  Attempt to load system pfile source C:\oracle\network\admin\sqlnet.ora
  Source of the setting successfully loaded

  Attempt to load the local pfile source C:\Dokumente und Einstellungen\lanadvall\sqlnet.ora
  The parameter source has not been loaded.

  This shows you which configuration files are read, followed by the settings real read.

  nnfloidinfocache: Info: insert the value DIRECTORY_SERVERS = oid.host.myorg.com:389 at index 0 in NLPA_CACHE

  nnflilc: conn sync opening of oid.host.myorg.com:389

  nnflfdn: turning simplified mydb.myorg.com name to a unique name.
  nnflfdn: using the administrative context: dc = prod
  nnflfdn: the domain name resulting is cn = mydb, cn = OracleContext, dc is myorg, dc = com

  nnflrne1: runs the directory for dn: cn = mydb, cn = OracleContext, dc is myorg, dc = com
  nnflqbf: search: Base: cn = mydb, cn = OracleContext, dc is myorg, dc = com, range: 0, filter: (objectclass = *)

  niotns: the call to address: (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST=dbserver.host.myorg.com) (PORT = 1521)) (CONNECT_DATA = (SID = DBNAME) (CID = (PROGRAM = C:\Oracle\ora1020\bin\sqlplus.exe)(HOST=pc247596)(USER=lanadvall)))
