end-of-file communication error

[raju_sbd]

Hi

I am trying to perform recovery of no-system datafile with rollback segments.

The steps I performed are:

sql> set transaction use rbseg1;
sql> create table test (num number) tablespace data1_ts;

- then inserted some values in the table.

- i shutdown the database using shutdown abort without performing commit on the above transaction to make the rollback segment have active transaction when shutting down the instance.

- then i deleted the datafile containing the rbseg1 rollback segment using os command

-removed rbseg1 entry in rollback_segments parameter in init.ora file

- then mounted the database..

- took the datafile containing rbseg1 offline..

- then tried to open the database using alter database open..

- then i got this error--"end-of-file- communication"..

Can somebody explain what is this error and how to perform recovery in this scenario.

Thanks in advance..
