• APEX 4.2.6 Upgrade with unique ORACLE_HOME supporting multiple databases

  We have a single server (Solaris) with a single ORACLE_HOME supporting multiple databases (all the 11.2.0.3 with APEX 3.0.2 installed).  A new database was created here just to make the development of the APEX.  It must be upgraded to APEX 4.2.6.  None of the old databases use APEX.  Upgrading replaces $ORACLE_HOME/apex.  What is the upgrade on the pre-existing database?  They will also release APEX upgraded?  Thank you.

  Hi Michael,

  If I understand your question, you want to upgrade APEX in the instance of a database. Fix?

  The upgrade of APEX can be done in a database without affecting other databases. Simply run the apexins.sql script in the database when you use APEX.

  Regarding the images in your $ORACLE_HOME/apex, it depends on the configuration of your Web server. You can configure your webserver (ADR, OHS, EPG) to get the images in the same directory or in another.

• I want to improve my server database Oracle 10 g 10.2.0.4, node 2 CARS on OS: release of Red Hat Enterprise Linux Server 5.3 (Tikanga)-version 2.6.18 kernel - 2.6.18 - 402.el5 to 128.el5.  This core does support my current 10.2.0.4

  I want to improve my server database Oracle 10 g 10.2.0.4, node 2 CARS on OS: release of Red Hat Enterprise Linux Server 5.3 (Tikanga)-version 2.6.18 kernel - 2.6.18 - 402.el5 to 128.el5.  This core does support my current Version of 10.2.0.4 or do I need to apply patches on the binary database after upgrading the kernel?

  Thank you

  Hello

  It should work without problem.

  According to the following document, you should have the kernel version 2.6.18 - 8 or higher.

  Oracle Database (RDBMS) under Unix AIX, HP - UX, Linux, Mac OS X, Solaris, Tru64 Unix operating system Installation and Configuration requirements checklist (8.0.5 to 11.2) (Doc ID 169706.1)

• Dblink Oracle to sql server, multiple database on the same server sql under a dblink

  Hi, we managed to set up an Oracle dblink to sql server and retrieve data.

  The user of sql server have been using via dblink has access to multiple databases on the same sql server

  But the question is how in oracle (if possible) prepend you the SQL access to this?

  For example:

  Sqlserver_prod has the user sqlserver_user which seems to be set up as default database sqlserver_db1

  But we have select access to sqlserver_db2

  all work well as sqlserver_user

  Select * from table_fromdb1

  Select * from dbo.table_fromdb1

  Select * from sqlserver_db1.dbo.table_fromdb1

  as does

  Select * from sqlserver_db2.dbo.table_fromdb2

  more in Oracle

  Oracle_db a dblink sqlserver_prod. World connection sqlserver_user

  everything works fine

  Select * from 'table_fromdb1"@sqlserver_prod '.

  Select * from 'dbo '. "table_fromdb1"@sqlserver_prod

  But how to (if possible) access from oracle

  sqlserver_db2.dbo.table_fromdb2

  without having to create a new sqlserver_db2_user referenced in a new dblink

  If oracle for oracle would be

  Select * from remote_oracle_schema.table@remote_oracle_db

  Hello

  You cannot select a table in a different SQL * database server from that to which the gateway instance connects.
  As stated in the documentation-

  Oracle® database gateway

  Installation and Configuration Guide

  11g Release 2 (11.2) for AIX 5 L Based Systems (64-bit), HP - UX

  Itanium, Solaris (SPARC 64-Bit), Linux x 86 operating system,

  and Linux x 86-64

  In the section.

  The example SQL Server multiple databases: Configuration of the modem router

  A separate instance of the gateway that is required for each SQL Server database. Each

  instance needs its own Gateway system ID (SID).

  ==========

  You will need to create a new instance of the gateway for the SQL * Server DB2 as well as a link separate db.

• DiscOrderedCursor and multiple databases

  Hi, EI 6.4 it is now possible to iterate over multiple databases with a DiscOrderedCursor which is a really great feature. But as far as I understand, it is not possible to distinguish to which database returned DatabaseEntries belong. I would use the DiscOrderedCursor for the use case, the following: 1. across all records in allmost all databases and perform different operations for each database. For the moment, we scan each database separately with a DiscOrderedCursor. 2. the reviews of a subset of the metering databases. For now, we call Database.count for each database. Thank you and best regards Arthur

  Hi Arthur,.

  I think you are looking for the DiskOrderedCursor.getDatabase method:

  http://docs.Oracle.com/CD/E17277_02/HTML/Java/COM/Sleepycat/je/DiskOrderedCursor.html#getDatabase)

  I'm glad you like this feature! Markos Zaharioudakis added this feature to the EJ.

• Is it possible to have multiple databases in a server?

  Hello:
  
  I have a quite stupid question, but it makes me doubt.
  Is it possible to have multiple databases in an Oracle Server? Are there so many bodies serving multiple databases on the Oracle server.?
  
  Thanks in advance
  
  Published by: user12229399 on 14-mar-2012 01:29

  Hello

  Yes, it's more than possible to have multiple instances on a single server.
  You can also have multiple versions (10g, 11g) on a single server.

  This means that you have several instances, i.e. multiple binary running oracle. You can also separate your data on a level diagram, i.e. a single instance serving multiple schemas.

• Cannot access the tables in other patterns of database Oracle

  Hello. We got our Oracle database administrator to install APEX in our Oracle database. She created a login and a schematic for my Oracle database user so that I can work with APEX a bit. Here is the information about the version of the SUMMIT we installed:

  I found that my user can access the Oracle tables within my own diagram of Oracle database. Most of our main tables are in 3 other schemas and I need access to all the tables of all these schemes. Now, whenever I meet a drop-down list of values for the schema, by own schema is available in the list of values.
  
  Is there something that our Admin can do to make these tables in other patterns available on my user account?

  Sharpe,

  This documentation should point you in the right direction. It will show you how to add multiple schemas to a workspace.

• Start up problem when having multiple databases on the machine

  Start up problem when having multiple databases on the machine:
  
  I installed two databases.
  
  When I stop the database and try to start using
  
  Startup pfile ='... location... " ;
  
  I get ora-12514: TNS: listener is not currently know of service rquirest in connect descriptor
  
  When I try again after 3 seconds, I get a new error, ora-01041: internal error. Hostdef extension doesn't exist
  
  Stop and start gave no problems when I had a database. Why I get problems when I have two databases?
  
  I use: show the pfile parameter. SPFile; to make sure that I have the right parameter locations, the error should not be the location.
  
  I never installed two databases on a single machine, then perhaps that I make mistake of a first - timer.
  
  Anyone know how to get this working, i.e. start and stop DB without problems?

  First of all... the Oracle Service for the instance must be started for the DB that you try to connect or start.
  Next... from the command prompt:

  Set oracle_sid =

  sqlplus sys as sysdba

  Startup pfile = 'location of the pfile respective db.

  Now, if you want to start or connect to another DB, which is on the same server (again assuming that the Service is STARTED)...
  From the same command prompt or other session...

  Set oracle_sid =

  sqlplus sys as sysdba

  Startup pfile = 'location of the pfile respective db.

• How do I know if my computer supports multiple screens or not?

  How do I know if my computer supports multiple screens or not?

  Most of PC graphics cards can run two monitors.
  There should be settings in the control panel for the card - for ATI CCC
  and the Nvidia for Nvidia Control Panel.
  You can also check with the mfg of your PC or the mfg of your graphics card
  For more information related to your card or a particular machine.

  ATI and Nvidia have the ability to run on two monitors with recent models and pilots.
