The ORA-04030 error is telling you that an Oracle process has requested memory from the operating system but the OS does not have any memory to give. Possible solutions include:

  1. Adding more physical memory (RAM) to the database server.
  2. Increasing the temp space on your database server and/or verifying that your temp disk is not full.
  3. Decreasing your database footprint so that it uses less memory. You may want to decrease the SHARED_POOL_SIZE and DB_CACHE_SIZE initialization parameters.
