To resolve this issue, refer to the below documentation provided by Oracle to install the Oracle Instant Client. If your windows is 64 bit, then download the 32 bit Oracle Instant Client from below link -
Pl Sql Developer Could Not Load Oci Dll
DOWNLOAD: https://gohhs.com/2vGasc
This happens because PL/SQL Developer is incapable of loading 64-bit version of oci.dll file. To fix this, download the 32-bit version of Oracle Instant Client, extract it to a directory such as \instant_client.
Bruno .. Boa tarde, estou enfrentando esse cenário, porém mesmo fazendo como segue o seu post eu ainda não consigo conectar ao pl/sql developer. Após baixar o client versão 32-bit pelo link indicado, a mensagem de erro ainda aparece agora :
Don't download oci.dll from a "DLL download" website. There are many reasons why downloading a DLL file is a bad idea. If you need a copy of this file, it's best to obtain it from its original, legitimate source.
The Microsoft ODBC components are packages in the Microsoft Data Access Component (MDAC) kit. Oracle ODBC driver on Windows has been tested using MDAC version 2.8. This can be downloaded from =ODBC+MDAC
Fetch Buffer Size - The amount of memory used to determine how many rows of data the ODBC Driver prefetches at a time from an Oracle database regardless of the number of rows the application program requests in a single query. However, the number of prefetched rows depends on the width and number of columns specified in a single query. Applications that typically fetch fewer than 20 rows of data at a time improve their response time, particularly over slow network connections or to heavily loaded servers. Setting Fetch Buffer Size too high can make response time worse or consume large amounts of memory.
The ODBC API supports both Unicode and ANSI entry points using the "W" and "A" suffix convention. An ODBC application developer need not explicitly call entry points with the suffix. An ODBC application that is compiled with the UNICODE and _UNICODE preprocessor definitions generates the appropriate calls. For example, a call to SQLPrepare is compiled as SQLPrepareW.
If a column that contains character data is not bound by SQLBindCol, the Oracle ODBC Driver must determine if it must fetch the column as Unicode or as the local code page. The driver could default to receiving the column as Unicode, however, this may result in as many as two unnecessary conversions. For example, if the data were encoded in the database as ANSI, there would be an ANSI to Unicode conversion to fetch the data into the Oracle ODBC Driver. If the ODBC application then requested the data as SQL_C_CHAR, there would be an additional conversion to revert the data back to its original encoding.
Applications that typically fetch fewer than 20 rows of data at a time improve their response time, particularly over slow network connections or to heavily loaded servers. Setting this too high can worsen response time or consume large amounts of memory. The default is 64,000 bytes. Choose a value that works best for your application.
In this example, an index on the HIREDATE column could be used to make the query execute quickly. But, because HIREDATE is actually a DATE value and the ODBC Driver is supplying the parameter value as TIMESTAMP, the Oracle server's query optimizer must apply a conversion function. To prevent incorrect results (as might happen if the parameter value had nonzero fractional seconds), the optimizer applies the conversion to the HIREDATE column resulting in the following statement:
None of these work. Luckily I use VPN. So the only thing that works is to disconnect the VPN and then connect back. It is a hassle and it is frustrating, but someone with this version of my PC, my trusted PL/SQL developer does not work
C:\app\sqldeveloper_4.0.2.15.21\sqldeveloper\bin;C:\Windows\Sun\Java\bin;C:\Windows\system32;C:\Windows;C:\app\Client\Jim.McCusker\product\11.2.0\client_64;C:\app\Client\Jim.McCusker\product\11.2.0\client_64\bin;C:\app\Client\Jim.McCusker\product\11.2.0\client_32;C:\app\Client\Jim.McCusker\product\11.2.0\client_32\bin;
I knew there could be some interoperability problems between versions, especially when the version gap is big like this case, Oracle 9i client connect to 12c, 18c or 19c database. But I didn't expect ORA-28040 to show up.
In fact, it depends on what privileges you have. For database administrators, you can change the server configuration to solve all users' problems at once. As for developers, fixing or upgrading Oracle clients is the only choice you can do, so as to match authenticated protocol of Oracle 12c databases.
If you have the right to change the network configuration on the server side, then you have chances to solve ORA-28040 for all users in minutes. As a matter of fact, most developers do not have the right.
Even though I see no chance to replace Oracle JDBC driver in the same old SQL developer, you can always download the newest SQL developer with newer Oracle JDBC driver from Oracle website. So as to solve ORA-28040.
PL/SQL developer is an install-based software. Generally, it leverages your native Oracle client to find necessary configuration file. Furthermore, it uses Oracle Call Interface (OCI) of your native Oracle client to connect Oracle databases.
The solution to ORA-28040 in PL/SQL developer is to replace the old OCI with a newer one. First of all, you have to download an Oracle instant client which contains corresponding OCI library. The proper version should be at least 11g.
In this case, I downloaded and installed Oracle client 11.2.0.1 for windows 32-bit from Oracle website. Consequently, the newly installed Oracle client creates some registry parameters like ORACLE_HOME and TNS_ADMIN as environment variables for tools like Toad to recognize. So that, the restarted Toad will automatically detect the new Oracle client for us.
How we handle it? This time, we don't have to upgrade the software like SQL developer to solve ORA-28040, because this tool allows us to replace Oracle JDBC Driver with a newer version. In this case, we replace the old driver ojdbc14.jar with newer ojdbc7.jar.
First of all, you have to choose and download a proper JDBC driver that matches the authenticated protocol of 12c database at Oracle JDBC and UCP Downloads page. For 12c databases, either ojdbc6.jar or ojdbc7.jar Oracle JDBC driver is proper to solve ORA-28040.
I was facing the same problem with ocijdbc11. Tried many things with Environment Variables and Registry with no effect. Then started using version 3.1, could use it without any problem. Now I have both version 2.1 that is having problem and not usable and also version 3.1 that is working perfectly.
im installing the sql developer but it shows some errors like# An unexpected error has been detected by HotSpot Virtual Machine: EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x77c47fd4, pid=308, tid=3696
Note: Iguana may not always support the very latest version of Oracle drivers, so you can simply download an earlier version if necessary. This is particularly true if you are not able to use the the latest version of Iguana.
If you are using a Wireless connection on campus, or you are off campus, VPN is required. Download the AnyConnect for Windows client from the Technology Help website. The connection guide is also on the Technology Help website.
Your account will give you access to public repositories that could be cloned but I suggest you create your own repository so that you can play with SQL Developer and see what the different options can do.
Update 07/15/2013: As Jeff suggested in the comments section, a recent version of ocijdbc11.dll (instant client 11.2.0.3) placed into the /sqldeveloper/bin directory fixed the issue. This is a temporary workaround until this is corrected in the GA version.
When I start SQL Developer, I could not use the OCI thick driver which is required when connecting via LDAP or TNSNAMES. SQL Developer was failing with error :ocijdbc11.dll: Can't load IA 32-bit .dll on a AMD 64-bit platform
Apart from changing the path in the Environment variables or in .bat file, it is possible to add the following line in sqldeveloper/bin/sqldeveloper.conf (where dbhome_2 is a 64bits home):AddVMOption -Djava.library.path=C:\oracle\product\12.1.0\dbhome_2\bin
I tried using your instructions to make Oracle SQL Developer point to Oracle 10.2 64 bits, but I am getting another error. Is it possible to make Oracle Developer to work with an specific version of Oracle? Here you can see all the information of my issue: -to-connect-to-oracle-with-sql-developer-and-oracle-10.Thanks!
Might be worth mentioning that you can copy sqldeveloper.conf to %APPDATA%\sqldeveloper\[version] if the original is in a read-only folder. Also in later versions there is a option to set the path for the Oracle Client in Tools > Preferences > Database > Advanced, although it seems sqldeveloper.conf is still useful for overwriting the default java.library.path.
To manually archive in Oracle 7, which still work, we could simply do :SQL> archive log listDatabase log mode No Archive ModeAutomatic archival DisabledArchive destination +DG_RECO01Oldest online log sequence 157Current log sequence 161SQL> archive log 161ORA-00259: log 1 of open instance DB01 (thread 1) is the current log, cannot archiveSQL> alter system switch logfile;System altered.SQL> archive log 161Statement processed.SQL>
First you need to get one certificate. There are many way to this, like Oracle Wallet manager or Microsoft Certmgr, but you could well use openssl. Using a selfsigned certificate is not a good idea.openssl.org
I could not miss this ! After offering free apex for non-productive usage (apex.oracle.com), free sql environment for playing (livesql.oracle.com), Oracle now offers free for ever infrastructure and database.
I gave it a try. It looks awesome. You have a server with an UNIX account. You have a database running, I could even set the region to Zurich, so the data stays in Switzerland. You can run webservices via ORDS and access them with your phones. Unlimited possibilities. 2ff7e9595c
