How To Solve Java.Lang.Unsatisfiedlinkerror: No Ocijdbc11 Inward Java
"java.lang.unsatisfiedlinkerror no ocijdbc11 inward java.library.path" mistake comes when you lot essay to connect to Oracle 11g database using OCI (thick) driver yesteryear using tns name, but the ocijdbc11.dll file is non available inward PATH or java.library.path environs variable. ocijdbc11.dll is a native library too if you lot know Java searches native library inward PATH or a place specified yesteryear java.library.path system property, if it doesn't notice the dll, too thus it throws java.lang.unsatisfiedlinkerror no ocijdbc11 inward java.library.path error. This dll is ordinarily constitute inward C:\Programs\Oracle\ora11g\bin\ocijdbc11.dll, but it could vary depending upon your Oracle installation.
The starting fourth dimension measuring to solving this mistake is a search for this dll inward your machine, if you lot are using windows, but search inward your C drive. If the dll is non at that spot too thus you lot take away to download that from Oracle's website. If it's already introduce too thus but add together its place into PATH variable.
If you lot are explicitly providing java.library.path too thus also supply it at that spot e.g.
-Djava.library.path=C:\Programs\Oracle\ora11g\bin\ocijdbc11.dll . By the way, if you lot really desire to larn Java database programming from scratch, I propose you lot accept a expect at Practical database programming alongside Java book yesteryear Ying Bai. This majority explains every of import exceptional of Java database connectivity.
By the way, this is non the measure way to connect to Oracle database from Java. Oracle users mainly role OCI driver for OS authentication or if they don't know the IP address of the server too desire to connect using TNSE, but if you lot are non concerned of that, you lot tin e'er role Oracle JDBC sparse driver to connect. For that, you lot but take away to include ojdbc.jar inward your classpath.
Just cry back if you lot role an OCI URL e.g. "jdbc:oracle:oci:/@"+tnsName too thus you lot are using thick driver too you lot take away oracle customer libraries on the PATH, for that you lot take away Oracle customer to survive installed on your machine, but if you lot role sparse driver alongside next URL format "jdbc:oracle:thin:@"+dbServer+":"+port+":"+SID; you lot but take away driver's JAR file too no native library volition survive required because its type four pure Java driver.
Btw, this is optional if you lot don't supply this organisation belongings Java volition expect on all folders included inward PATH environs variable.
If you lot don't notice this dll file too thus you lot take away to install Oracle customer to acquire this dll. If you lot install Oracle 11g inward 64-bit Windows vii machine too thus this native library tin survive constitute inward C:\Programs\Oracle\ora11g\bin\ocijdbc11.dll folder. Now but add together this folder to your PATH too run your programme again, provided whatever other mistake you lot should survive able to connect to Oracle server.
The instant solution is to use Oracle JDBC sparse driver to connect Oracle database. For this you lot take away to alter your JDBC URL format equally "jdbc:oracle:thin:@"+dbServer+":"+port+":"+SID; too include ojdbc6.jar inward to your CLASSPATH.
Always cry back the deviation betwixt PATH too CLASSPATH, PATH is used to locate executable files, native library files but JAR is e'er loaded from the classpath. This is also the measure way to connect to Oracle 11g database.
You tin also run across Core Java Volume II - Advanced Features yesteryear Cay S. Horstmann to larn to a greater extent than almost database programming inward Java using JDBC. One of the consummate majority to larn Java.
For the thick driver, you lot take away ocijdbc11.dll inward your PATH too for the sparse driver, you lot take away ojdbc6.jar or ojdbc6_g.jar, afterward 1 is a debug version. So if you lot acquire this mistake spell using SQL Developer, follow the to a higher identify measuring to variety it out.
If you lot are using Oracle 10g too thus you lot volition probable to run across java.lang.unsatisfiedlinkerror no ocijdbc10 inward java.library.path, the solution is same notice the dll too add together into PATH. Also, ojdbc6.jar tin survive constitute inward C:\Programs\Oracle\ora11g\jdbc\lib\ location, where ORACLE_HOME.
Since this is also a type of java.lang.unsatisfiedlinkerror, you lot tin also run across this tutorial to acquire a full general persuasion almost how to solve this mistake inward Java. You volition probable to run across this type of mistake whenever your Java programme volition role native libraries, either internal or external to create stuff.
That's all almost how to fix java.lang.unsatisfiedlinkerror no ocijdbc11 inward java.library.path mistake in Java. You acquire this mistake when you lot essay to connect to an Oracle 11g database from Java programme yesteryear using its TNS cite too non the IP address. You tin ready this mistake yesteryear adding ocijdbc11.dll inward your PATH environs variable or into your java.library.path variable.
If that DLL is non available inward your organisation too thus download too install Oracle customer similar SQL Developer, which contains both thick too sparse JDBC driver to connect to Oracle database.
If you lot get java.lang.unsatisfiedlinkerror no ocijdbc10 inward java.library.path agency you lot are connecting to Oracle 10g database but the solution is same alongside the exclusively deviation inward Oracle version difference. Let us know if you lot confront whatever upshot spell connecting to Oracle database from Java too I volition essay to aid you lot here.

The starting fourth dimension measuring to solving this mistake is a search for this dll inward your machine, if you lot are using windows, but search inward your C drive. If the dll is non at that spot too thus you lot take away to download that from Oracle's website. If it's already introduce too thus but add together its place into PATH variable.

Error :
Exception inward thread "main" java.lang.UnsatisfiedLinkError: no ocijdbc11 inward java.library.path at java.lang.ClassLoader.loadLibrary(Unknown Source) at java.lang.Runtime.loadLibrary0(Unknown Source) at java.lang.System.loadLibrary(Unknown Source)
Analysis :
If you lot expect at the mistake you lot volition notice that Java is complaining that ocijdbc11 dll is non constitute inward java.library.path. If you lot farther expect too thus you lot volition country that Oracle Driver is using System.loadLibrary() method to charge the native library, which explains why Java is searching for dll inward java.library.path.Btw, this is optional if you lot don't supply this organisation belongings Java volition expect on all folders included inward PATH environs variable.
Solution:
There are ii ways to solve the problem, starting fourth dimension banking firm tally if ocijdbc11.dll is introduce inward your machine or not. For that create a broad search on your C driver where programs are installed.If you lot don't notice this dll file too thus you lot take away to install Oracle customer to acquire this dll. If you lot install Oracle 11g inward 64-bit Windows vii machine too thus this native library tin survive constitute inward C:\Programs\Oracle\ora11g\bin\ocijdbc11.dll folder. Now but add together this folder to your PATH too run your programme again, provided whatever other mistake you lot should survive able to connect to Oracle server.
The instant solution is to use Oracle JDBC sparse driver to connect Oracle database. For this you lot take away to alter your JDBC URL format equally "jdbc:oracle:thin:@"+dbServer+":"+port+":"+SID; too include ojdbc6.jar inward to your CLASSPATH.

java.lang.unsatisfiedlinkerror no ocijdbc11 inward java.library.path inward SQL Developer
After Toad, Oracle's SQL Developer is the adjacent pop tool for connecting to Oracle database too this a Java client. That's why you lot take away both thick too sparse driver inward your machine, which I gauge also comes when you lot install SQL Developer. It uses the thick driver when using TNS cite too sparse driver when using the basic connection.For the thick driver, you lot take away ocijdbc11.dll inward your PATH too for the sparse driver, you lot take away ojdbc6.jar or ojdbc6_g.jar, afterward 1 is a debug version. So if you lot acquire this mistake spell using SQL Developer, follow the to a higher identify measuring to variety it out.
If you lot are using Oracle 10g too thus you lot volition probable to run across java.lang.unsatisfiedlinkerror no ocijdbc10 inward java.library.path, the solution is same notice the dll too add together into PATH. Also, ojdbc6.jar tin survive constitute inward C:\Programs\Oracle\ora11g\jdbc\lib\ location, where ORACLE_HOME.
Since this is also a type of java.lang.unsatisfiedlinkerror, you lot tin also run across this tutorial to acquire a full general persuasion almost how to solve this mistake inward Java. You volition probable to run across this type of mistake whenever your Java programme volition role native libraries, either internal or external to create stuff.
That's all almost how to fix java.lang.unsatisfiedlinkerror no ocijdbc11 inward java.library.path mistake in Java. You acquire this mistake when you lot essay to connect to an Oracle 11g database from Java programme yesteryear using its TNS cite too non the IP address. You tin ready this mistake yesteryear adding ocijdbc11.dll inward your PATH environs variable or into your java.library.path variable.
If that DLL is non available inward your organisation too thus download too install Oracle customer similar SQL Developer, which contains both thick too sparse JDBC driver to connect to Oracle database.
If you lot get java.lang.unsatisfiedlinkerror no ocijdbc10 inward java.library.path agency you lot are connecting to Oracle 10g database but the solution is same alongside the exclusively deviation inward Oracle version difference.
