3. Change to the eclipse/tools subdirectory in the directory where you installed Installation Manager.
4. Use the imcl command to uninstall the product.
   

   imcl.exe uninstall com.ibm.websphere.BASE.v85,optional_feature_ID
     -installationDirectory installation_directory

   • You can remove a list of features that are separated by commas:
     • core.feature indicates the full WebSphere Application Server profile
       • samples indicates the sample applications feature
       • thinclient indicates the standalone thin clients and resource adapters
       • embeddablecontainer indicates the embeddable EJB container

IBM WebSphere SDK Java™ Technology Edition Version 7.0 is such an extension.
