Oracle 10g Download For Windows 7 64 Bit 200
Oleta Blaylock
Now , the last few after hours patching reboots (database is open during the reboot) this one db doesn't come up with the windows service. Even after all the users log off before the shutdown. Nothing is obvious in the alert.log file.
Any thoughts on what to check or change to ensure the db does proper cleanup on startup.. assuming I don't shut it down clean, which is not always an option. The windows service is set to automatic, naturally. There are 2 11g databases on this server.
I have an application that reads PC time zone information using GetTimeZoneInformation. Then when I establish connection to Oracle I need to 'alter session set time_zone = '. If I use just the offset, oracle will disregard daylight saving settings, so I need to specify time zone name. However oracle has over 2000 records in v$timezone_names table, none of them matching the time zones Windows returns via tzutil or GetTimeZoneInformation. Is there any way to convert the time zone windows returns to corresponding time zone in oracle, considering I need to keep dayluight saving settings.

It's been long that I had downloaded and installed the oracle client. Please help and advise me to direct me to the link to download the complete oracle client installation 19c? Basically we need to install oracle client to support our end users and developers to be able to use a SQL developer and SQL*plus to connect to the database.
But I'm still getting "DataSource.Error: The provider being used is deprecated: 'System.Data.OracleClient requires Oracle client software version 8.1.7 or greater.'. Please visit =272376 to install the official provider."
What worked for us here was uninstalling 12.2 and then installing 12.1 . We grabbed the newest link off the oracle site without thinking about it, but I guess microsoft specifies the version for a reason. Powerbi doesn't appear to play nicely with 12.2
I couldn't get Power BI Desktop to work with the Oracle19 ODAC tools. However a clean install of The full ODAC tools for 12.2.0.1.1 did work. I didn't need to install an "Oracle Client" at all.
NOTE: Make sure to check the box about installing the drivers machine wide.
So it seems Power BI Desktop doesn't see the drivers because Oracle no longer installs them at the machine level. If someone smarter than me with ODP.NET knows how to add that machine level configuration, I would be interested in trying it out.
I have ODAC 19.3 working with some help from google. I'm going to post it as a new topic, rather than hide it down here, so that it's easier to find. Once I've posted it I will come back add add a link to it.
So, I am really new to this stuff and there seems to be several files to download, can you refer me to the link in Oracel or file name of what I should download? Thanks for responding, your post is a few years old now lol
Is this what you refer to as oracle home the the ODAC should have installed in client_1 folder. How do I achieve this in the installation? (I guess I have to specify some other than the default path).
I have installed a complete test environment on my virtual PC consisting of oracle database, oracle business intelligence servers. So I probaly have another scenario than end users that do not run the DB server and fusion middelware on the computer.
I have had a lot of problems during installation of these components but have always figures a way around it, so I guess you have found the answer to this final issue of the Power BI / Oracle test envrionment installation.
Thanks for the help. I now installed a second time (using VM machine I could revert to before the first installation) then I change the installation path to client_1 instead of client_2. I got past the messages saying I did not have correct ODAC installed.
Power BI Desktop needs the Oracle data providers installed at the machine level. After ODAC 12.2, Oracle removed this option from the install, which means out of the box Oracle 18.x and 19.x ODAC installs are not seen by Power BI Desktop. I've spent the last 24 hours installing and uninstalling various versions of ODAC trying to get them to work with Power BI Desktop.
I'm limiting this to the 64bit install (Because that is what I have) and .NET 4.0, becuase that is what Power BI Desktop needs.
I can now report I have ODAC 19.3 working with Power BI Desktop (May 2021). This is thanks to Google and a lot of digging around. I've put a link to the original article I found that helped me get the data providers installed, as this was not my own work! (Power BI Github comment ), I'm just documenting it here for others.
Check your Windows environment variables. Is the Oracle client you are trying to use the first oracle path in the PATH variable? Do you have TNS_ADMIN defined and pointing to a valid tnsnames.ora directory?
After all the hours spent trying to solve this issue it was my companies rolled out version of PBI Desktop. It was right in the article I had read 100 times but skimmed over because I have PBI desktop pushed to my machine. I had to have IT remote in to install.
If you downloaded Power BI Desktop from the Microsoft Store, you might be unable to connect to Oracle databases because of an Oracle driver issue. If you encounter this issue, the error message returned is: Object reference not set. This is an issue with how Oracle driver works in Windows UWP Apps. To address the issue, you have to do the following:
The cx_Oracle module loads Oracle Client libraries which communicateover Oracle Net to an existing database. Oracle Net is not a separateproduct: it is how the Oracle Client and Oracle Database communicate.
Add Oracle 21, 19, 18, 12 or 11.2 client libraries to your operating systemlibrary search path such as PATH on Windows or LD_LIBRARY_PATH onLinux. On macOS use init_oracle_client() in yourapplication to pass the Oracle Client directory name, seeUsing cx_Oracle.init_oracle_client() to set the Oracle Client directory. This is also usable on Windows.
Instant Client on Windows requires an appropriate Microsoft WindowsRedistributables, see Installing cx_Oracle on Windows. On Linux, the libaio(sometimes called libaio1) package is needed. Oracle Linux 8 alsoneeds the libnsl package.
Version 21 client libraries can connect to Oracle Database 12.1 or greater.Version 19, 18 and 12.2 client libraries can connect to Oracle Database 11.2or greater. Version 12.1 client libraries can connect to Oracle Database 10.2or greater. Version 11.2 client libraries can connect to Oracle Database 9.2or greater.
Locate your Oracle Database username and password, and the databaseconnection string. The connection string is commonly of the formathostname/servicename, using the hostname where the database isrunning, and using the service name of the Oracle Database instance.
cx_Oracle requires Oracle Client libraries. The libraries provide thenecessary network connectivity to access an Oracle Database instance.They also provide basic and advanced connection management and datafeatures to cx_Oracle.
cx_Oracle uses the shared library loading mechanism available on eachsupported platform to load the Oracle Client libraries at runtime. Itdoes not need to be rebuilt for different versions of the libraries.Since a single cx_Oracle binary can use different client versions andalso access multiple database versions, it is important yourapplication is tested in your intended release environments. NewerOracle clients support new features, such as the oraaccess.xml external configurationfile available with 12.1 or later clients, session pool improvements,improved high availability features, call timeouts, and other enhancements.
The cx_Oracle function clientversion() can be used todetermine which Oracle Client version is in use. The attributeConnection.version can be used to determine which Oracle Databaseversion a connection is accessing. These can then be used to adjust applicationbehavior accordingly. Attempts to use Oracle features that are not supported bya particular client/server library combination will result in runtime errors.
This will download and install a pre-compiled binary if one isavailable for yourarchitecture. If a pre-compiled binary is not available, the sourcewill be downloaded, compiled, and the resulting binary installed.Compiling cx_Oracle requires the Python.h header file. If you areusing the default python package, this file is in the python-develpackage or equivalent.
If you use optional Oracle configuration files such as tnsnames.ora,sqlnet.ora or oraaccess.xml with Instant Client, then put the filesin an accessible directory, for example in/opt/oracle/your_config_dir. Then use:
Alternatively, put the files in the network/admin subdirectory of InstantClient, for example in /opt/oracle/instantclient_21_1/network/admin.This is the default Oracle configuration directory for executables linkedwith this Instant Client.
Alternatively, for version 18 and earlier, every shell runningPython will need to have the environment variableLD_LIBRARY_PATH set to the appropriate directory for theInstant Client version. For example:
