ORA_RMAN_SGA_TARGET

assume that we lost all the files of oracle database but we do have rman backup, when trying to bring up a dummy database before restore start, I get this error.

RMAN> startup nomount force;

There are two possible solutions:


1- Create temporary init.ora file (/oracle/product/11.2.0/db_1/dbs/initTEST.ora) with the following parameters:


db_name=
large_pool_size=100m
shared_pool_size=250m
db_cache_size=10m


2- Set environment variable ORA_RMAN_SGA_TARGET before executing rman. For example:


$ export ORA_RMAN_SGA_TARGET=350

RMAN> startup nomount force;

now the database is at nomount status, I can start to restore spfile,controlfile and database now.

    How do we restore spfile from sbt_tape to another host?

    Prakash,

    have you tried the following? I did not, but just a thought.

    rman catalog username/password@catalog target /
    set dbid= xxxx;
    list backup of spfiles;
    restore spfile to pfile='/location'

oracle dba_hist_sysmetric_summary

found this blog is helpful to get CPU and IO statistics on oracle database. http://shob-dbadmin.blogspot.ca/2012/12/how-to-find-total-io-of-database.html courtesy to  Shomil Bansal , below are hist writing, not mine. How to find total IO of the database instance Total IO of database instance is sum of the physical reads, physical writes and redo writes. There are several views to find these values. v$sysmetric  - Reports metric values for only the most current time sample 60 secs. v$sysmetric_summary  - Reports metric values for time sample of 1 hour. v$sysmetric_history  - Reports metric values every 60 sec from the time instance is up. Better way to analyse IO using this view to take deltas between two time periods. dba_hist_sysmetric_history  - All the above views are refreshed when the instance is restarted. This view, part of AWR, stores the historical stats. I have used this view for my report. Query: ====== set lines 350...
