Select failover ORA-25401 when data is imported from an export on a RAC cluster

  We were told by consultants that on our production 2 node cluster (64-bit RedHat linux, RAW using ASM) database that after importing data into a new schema, the select failover was not functioning.

      The data was imported into a new schema in a clustered db instance (2nodes). A huge select statement was run and a node was taken down to test select failover. Once the node was taken down the select statement issued the following message:    

  "ORA-25401 can not continue fetches" when selecting from a table from 1 node, and shutting down node to test failover selects.        

  The TAF looks like:
  (DESCRIPTION =

(ADDRESS = (PROTO = TCP)(HOST = oraclea1-vip)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = oraclea2-vip)(PORT = 1521))
(FAILOVER = yes)
(LOAD_BALANCE = yes)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = IUAT_TAF1.ascendanalytics.com)
(FAILOVER_MODE =
(TYPE = SELECT)
(METHOD = BASIC)
(RETRIES = 180)
(DELAY = 5))))
   

  To get this to work, we had to import the data into a temporary schema, then from the real schema we want, we did a create table xxx as ... from the temp schema we imported the data into.        

  Thanks again for any suggestions.    

  I also have an attachement of the scr if you are interested. Doesn't look like I'm allowed to post attachments.
