The developer team wants to test their application. For the same they need some data which resides at oracle 8i instance. However they are not able to create a dblink between 11g and 8i as this is not supported by oracle.
Now they want the data to be refreshed from 8i to 11g by exp/imp.
Apart from exp and imp is there is any other alternatives?
"Oracle parse sql and stores explain plan, if the same sql comes again then oracle don't parse it again (soft parse) and gets the explain plan through cursor sharing."
Is there any parameter through which I can set cursor_sharing refresh interval to generate new execution plan?
I will have to proceed with Oracle 9 database refresh from production server to integration server. 5 biggest schemas must be exported and imported. They constitute 97% space used in a database. This is very big database so I would like to be sure that everything will go smoothly. That is why i want to ask you some questions.
Have you got any clues for me before I start with exp/imp? From my side i will tell you that I will have to exp/imp schema by schema because there is small space both on production and integration disk for a dump. First thing I thought are dependencies between schemas that are exported and that which are not, and also between schemas that are exported/imported one by one.
This is procedure that I plan:
For every schema that is to be refreshed
{
1. Export schema with ROWS=N CONSTRAINTS=Y
2. EXPORT schema with ROWS=y CONSTRAINTS=N
3. Import schema from step one
4. Disable all the foreign key constraints using ALTER TABLE DISABLE CONSTRAINT.
5. Import schema with rows
}
ALTER TABLE ENABLE CONSTRAINT
With above procedure i think that I will avoid problems with dependencies between schemas exported/imported one by one. But my concern is if there are any dependencies between those schemas and schemas that are not exported. Is there an way to check it before refresh ?

i want to perform full export + import of an oracle 11g database as fast as possible. i was thinking to perform the exp+imp on the same command.in exp i can perform something like this :
mknod /oracle/migration/exp_pipe p
exp '/ AS SYSDBA' file= /oracle/migration/exp_pipe full=y | imp system/***@oracle_db file= /oracle/migration/exp_pipe full=y
i know that i can do both action in impdp when using a dblink, but the problem is that some objects in the database cannot be copied via a dblink. the question is if there's a corresponding datapump command to the old exp+imp command i presented.
i have Oracle 10g data guard set up on windows environment.....i need to know the what are the right steps to perform failover in case the primary database gets fail.

I am getting ORA -32320 when I tried to fast fresh MVs that were truncated.I am able to complete refresh all MVs. However, some MVs are still giving me ORA-32320 when I try to do fast refresh even after complete refresh.

DB_VERSION=10.2.0.4
OS_VERSION=Windows 2008 R2
RAM_SIZE=32 GB
We have 2 production (OLTP) database( DB1 (18GB) and DB2 (200GB) ) on a server out of which DB2 database has almost 20 Materalized Views all (REFRESH FORCE ..ON DEMAND).
I have already informed the client that this is not the OLAP database where you are going to make use of the M Views for reporting purpose. However currently the client does not have any alternative.
Breif details :-
Out of 20 M Views 3 refresh once a week and where as the rest refresh every night daily.
We are currently testing a new website for which we had to re-schedule all M Views from their Old timings to New Timings i.e. Daily Basis.
But post re-scheduling the database performance was badly degarded as the database was too slow also the number of archives increasted to 300GB which was earlier 100 GB.To resolve the issue , we had to go back to the old timings and the database is currently working fine.
Requirement :-Client is looking out for an alternative solution as he needs to once again change the M View refresh time i.e. Daily Refresh.We already have 2 Oracle Instance on the server
Questions :-
1. Can i create another database ( sayTESTDB2 ) in no archivelog mode and create a db link to reduce the load on the server ?
2. If Yes .. Then is there any relavent link /example or Metalink Note ID for the same??
3. What all parameters do i need to consider while creating a DB Link ?
3. Out of 32 GB RAM , I have given 4GB and 8GB sga_max to DB1 and DB2 Respectively . Also the cpu utilization is normally 50-%60%.
Since currently we do not have any Licence for other server .. Can i make use of the same server ( i.e. creating 3 rd Oracle Instance )?
Since the main intention of this activity is reduce the load from the DB2 onto TESTDB when the daily refresh has set once again
