we have a database on a single instance having size 15GB and using file system  for storage.

we want to migrate that database (full exp/imp) into a new RAC database which is using ASM.

what are the options i had?

for full exp/imp, i can take the full exp from single instance database (which is using file system)
then how to import into RAC database (2-node) having ASM?

following are my questions.......

1) on 2node RAC, we have 2 instances up and running.
    so can i import through one instance ??

2) how to  importing from  non-ASM to ASM??

15gb isnt much, so easiest option is probably to use expdp and impdp. The fact that you are importing into RAC using ASM doesn't matter. You can connect to a single instance if you like, or to a load balanced service name, it makes no difference.


>>  to a load balanced service name,

can you please explain it? i didn't understand it....

Sorry, I assumed you understood some RAC concepts. When you connect to a database, you use might usually use its SID as defined in a tnsnames.ora file. A service name is just a different name you can use to connect to the database, but it has some built in smarts around load balancing and failover for RAC nodes.

When running expdp/impdp all you care about is the name used in your connection string.

Follow MrNed answer. I will just add to make it simple. Since you already have the 2-Node RAC with 2-instances. On any one node, make sure that your environment is pointing to the desired instance. i.e your ORACLE_HOME and SID is set to correct instance. Run impdb as system with FULL=Y option. Make sure you have created Tabelspaces with same name as on the source database to make it simple  or you have options to use REMAP_TABLESPACE and  REMAP_DATAFILE with impdb.


thanks it works!!!

When you do a impdp into a RAC db is faster if you shutdown one of the nodes (or just have 1 up) do the import and start it (the nodes) again after the import.
