Steps to be taken for customers using custom RADs

It should be noted that a number of RAD and Device Scripts have been changed in Drivers 24 and that if you have tailored any of the default RAD and Device Scripts on the affected drivers previously that you will need to reapply your changes after installing Drivers 24. If you have custom RADs for any drivers, replace the existing RAD with the new RAD and re-implement the custom modifications or compare the new RAD with the existing RAD and make the necessary changes. These changes mainly concern setting the SSH version to 2 and a 256-bit cipher.

UOWs may fail due to out of memory errors on Juniper devices

Due to the large size of the Juniper drivers, device imports and other UOWs may fail due to out of memory errors, which can be seen in the UOW logs. It is recommended that customers using Juniper drivers increase their client and server memory settings. The following list identifies the settings to specify for the system properties associated with client memory, driver memory, and schema scale factor.

Important: The Memory Manager - Memory Reserved For Drivers and Memory Manager - Schema Scale Factor system properties are not normally to be modified except under the direction of IBM Support. However, to avoid the out of memory errors on Juniper devices it is necessary to configure these properties as described here.

Minimum Client Memory: Set this system property to the value 512m (512 MB)
Maximum Client Memory: Set this system property to the value 2024m (2024 MB)
Memory Manager - Memory Reserved For Drivers: Set this system property to 1024m (1024 MB)
Memory Manager - Schema Scale Factor: Set this system property to the value 2.8.

For instructions on modifying the Minimum Client Memory, Maximum Client Memory, and other system properties, see Modifying system properties.

Note: After modifying the previously listed system properties, exit the System Properties window and exit the GUI. Then, reopen the GUI and reopen the System Properties window. The modified values should now be available.

To modify the settings for the server memory parameters, follow the steps in Increasing the Java Heap size
