You can perform the following steps in your IBM Spectrum Control version 5.4.11 to mitigate Apache Derby issue

• Login to the system where IBM Spectrum Control is installed.
• Stop all the IBM Spectrum Control services. For more information, see <https://www.ibm.com/docs/en/spectrum-control/5.4.11?topic=administering-starting-stopping-spectrum-control-servers&gt;
• Delete derby.jar and derbytools.jar manually from the following path in the IBM Spectrum Control installation folder.
  • <IBM Spectrum Control-install-location>/lib
  • For example, C:\program files\IBM\TPC\lib
• Delete the “org.apache.derby.jdbc” package entry from MANIFEST.MF in TPC_GUI.jar, by performing the following steps.

** For the Windows operating system:**

1. 1. Take a backup of <IBM Spectrum Control-install-location>/lib/TPC_GUI.jar file before update.
   

2. Extract the <IBM Spectrum Control-install-location>/lib/TPC_GUI.jar file using the tool like 7-zip.
3. Navigate to the META-INF folder and open MANIFEST.MF for editing.
4. Delete the text "org.apache.derby.jdbc," from MANIFEST.MF file and save it.
5. Close the file and 7-zip tool.

** For Linux or /AIX operating system:**

1. 1. Take a backup of <IBM Spectrum Control-install-location>/lib/TPC_GUI.jar file before update.
   

2. Create a test directory in <IBM Spectrum Control-install-location>/lib and copy TPC_GUI.jar in the test directory.
3. Navigate to the test directory and unzip TPC_GUI.jar by using the following command. 
  * "unzip TPC_GUI.jar META-INF/MANIFEST.MF -d ."
4. Use any editor like "vi" to edit MANIFEST.MF. 
  * "vi META-INF/MANIFEST.MF" 
5. Delete the text "org.apache.derby.jdbc," from the MANIFEST.MF file. Save the file and exit the editor.
6. Repackage modified MANIFEST.MF to TPC_GUI.jar file by using the following command. 
  * "zip -u TPC_GUI.jar META-INF/MANIFEST.MF"
7. Copy the modified jar TPC_GUI.jar back to <IBM Spectrum Control-install-location>/lib directory.
8. Delete the test directory.

• Start all IBM Spectrum Control services. For more information, see <https://www.ibm.com/docs/en/spectrum-control/5.4.11?topic=administering-starting-stopping-spectrum-control-servers&gt;
