Use this page to make a library file available to deployed applications.
To view this administrative console page, click Environment > Shared libraries > shared_library_name.
Specifies the level of the location of the shared library configuration file.
On single-server installations, the shared library has its configuration file in a location that pertains to the cell, node, or server level.

Specifies a list of paths that the product searches for classes and resources of the shared library.
If a path in the list is a file, the product searches the contents of that Java archive (JAR) or compressed .zip file. If a path in the list is a directory, then the product searches the contents of JAR and compressed files in that directory. For performance reasons, the product searches the directory itself only if the directory contains subdirectories or files other than JAR or compressed files.
Press Enter to separate class path entries. Entries must not contain path separator characters such as a semicolon (;) or colon (:). Class paths can contain variable names that can be substituted using a variable map.

Units | Class path |
Specifies the class path for locating platform-specific library files for shared library support; for example, .dll, .so, or *SRVPGM objects.
If you specify a value for Native library path, the native libraries are not located by application or shared library class loaders unless the following conditions exist:
For example, in the class that loads the native library, call System.loadLibrary(native_library) in a static block:
static {System.loadLibrary("native_library");
Native libraries cannot be loaded more than once by a class loader. Thus, it is preferable for native libraries to use an isolated shared library or to be loaded within shared libraries associated with the class loader of an application server. See the Use an isolated class loader for this shared library setting.

Data type | String |
Units | Class path |
Specifies whether the shared library has a single isolated shared library shared across its associated applications or web modules.
An isolated shared library enables one instance of the library classes to be shared only among associated applications and web modules. An isolated shared library enables multiple applications or web modules to share a common set of classes across a subset of the applications. Further, an isolated shared library supports versioning and loads the minimum number of library copies. The class loader created for an isolated shared library does not reload and, like a server class loader, exists for the lifetime of a server. For shared native libraries, you can use an isolated shared library to avoid errors resulting from reloading of native libraries.
The default, false, is not to isolate the shared library so that each application loads its own instances of the shared library classes.
Using an isolated shared library can reduce the memory footprint when a large number of applications share the library. If you select this option, associate the shared library with applications or Web modules.
This setting maps to the isolatedClassLoader Boolean attribute of the Library object.
