The ORA-4030 error occurs when a user tries to create a connection to the database and there is not enough memory to allocate their dedicated server process. You have two options. First, you could increase the memory on your server and talk to your SysAdmin to make sure that the memory is available. Second, you can decrease the amount of memory that is attempted to be allocated for the dedicated server process. You do this by decreasing your SORT_AREA_SIZE, HASH_AREA_SIZE, and/or CREATE_BITMAP_AREA_SIZE.
