I've got one database which was Initially upgraded from Oracle 8i to 10.2.04 running on windows. Most of the tabespaces are Dictionary managed. Do you think moving them to locally managed tablespace would give me better performance?
if Yes, what approach I should apply to move them to locally managed? I would like to do this with minimum/no downtime.
I have one database which is recently upgraded from oracle 8.1.5 to oracle 10.2.0.4.The database is having around 300 tablespace and total size of the database is 1.5 TB.
The database was created in oracle 8i and all the teblespace were DMT(Dictionary Managed Tablespace) .Usually after up gradation all the tablespace are in DMT mode. Now my requirement is to convert all the tablespace into LMT (Locally Managed Tablespace) so that I can AVAIL ALL THE FEATURES OF LMT.
This database is a mission critical database and very less downtime can be allowed.
How we can create dictionary managed temporary tablespace in Oracle 10g.
SQL> create temporary tablespace temp

create temporary tablespace temp
ERROR at line 1:
ORA-25139: invalid option for CREATE TEMPORARY TABLESPACE
I can see that some failover events etc aren't supported (Differences between the ODP.NET Managed Driver and Unmanaged Driver), but is failover supported at all? I don't need to get notified, just to get the failover (clustered node switching) working. Is it supported in the managed driver?

I am trying to use oracle wallet with the new odp.net managed driver, but I am getting

View 3 Replies View Relatedat my Oracle 11gR2 (11.2.0.3.0) Instance i have two tablespaces that i want to "bundle" into only one tablespace. Herre is the problem, that some of the tables in the two tbalespaces has the same title but some rows of the tables could be not the same.
Is it possible with a kind of migration assistent to migrate two tablespaces into one in that way, that theassistent only writes that rows into the new tablespace, that are not in the tablespace at the moment.
Another way i was thinking about is to have an insert statement coupled with a select statement. The select statement selects all the rows, that are not in the table where i want to migrate in and the insert statement put that selectet rows into the new table.
Is something of that possible?
Question 1) I have read the following statement in a PL/SQL book.
Quote:To check whether an existing procedure is compiled for native execution or not, you can query the following data dictionary views:
[USER | ALL | DBA]_STORED_SETTINGS
[USER | ALL | DBA ]_PLSQL_OBJECTS
However, I when i query the view USER_PLSQL_OBJECTS I get the following error message:
Quote:ORA-00942: table or view does not exist
Question 2) I have read the PLSQL_WARNING can be set to DEFERRED at the system level. However, I am unable to defer it. tell me how to apply defer caluse to following statement:
Quote:ALTER SYSTEM SET PLSQL_WARNINGS ='DISABLE:ALL'
I'm supposed to create a database for an application. The server where this will be running previously had a database for a pretty similar app. I don't know much about Oracle so I reused the ZFS filesystems and left them how they were created (because honestly, I didn't knew why they were created that way, but I'm pretty sure it was for a good reason).
CODEapp/oradata_smart_ora1 858M 12.2G 858M /oradata/SMART/ora1
app/oradata_smart_ora2 7.18M 18.0G 7.18M /oradata/SMART/ora2
app/oradata_smart_ora3 7.18M 36.0G 7.18M /oradata/SMART/ora3
app/oradata_smart_ora4 60.6K 400G 60.6K /oradata/SMART/ora4
app/oradata_smart_redo1 400M 2.61G 400M /oradata/SMART/redo1
app/oradata_smart_redo2 200M 2.80G 200M /oradata/SMART/redo2
app/oradata_smart_redo3 200M 2.80G 200M /oradata/SMART/redo3
Since I reused the filesystems I created my database and placed the controlfiles in the same places where the old database files were (/oradata/SMART/ora1,/oradata/SMART/ora2,/oradata/SMART/ora3). Thinking like MySQL works I created CODEapp/oradata_smart_ora4 60.6K 400G 60.6K /oradata/SMART/ora4 specifically to store the database there.
The databases startups and mounts no problem. Note that this server will manage with millions/billions records throughout its lifetime.
1. Now that my Database is created, whats the next step? Create the Schema or Tablespace?
2. Tablespace Questions: Tablespace datafile(s) is where actual data from tables is stored? how many are needed? Default or Temporary? How much space will I need for it? Autoextend?
I have a Physical Standby database on server#2 which has its UNDO and TEMP tablespaces in a mount point that is a bit small. I discovered yesterday that this mount point was completely filled. This is not an immediate problem, because even though the TEMP and UNDO tablespaces are large, there is almost no usage of them.
I logged into my Primary, and created a new temp tablespace (TEMP2), made it the database default, dropped the TEMP tablespace, and then re-created the TEMP tablespace in a different mount point (with a much higher capacity!). I then made the new TEMP as the database default temp tablespace again. I expected that these changes would be propagated over to the Physical Standby via log application, but they didn't come over.
I have standby_file_management set to AUTO, and there are no unapplied logs. Everything OTHER than the temp tablespaces seems to be in synch.
I created table that is range partitioned:
CODEPARTITION t1p1 VALUES LESS THAN (TO_DATE('2011-11-01', 'YYYY-MM-DD'))
PARTITION t1p2 VALUES LESS THAN (TO_DATE('2011-11-02', 'YYYY-MM-DD'))
....
PARTITION t1p4 VALUES LESS THAN (MAXVALUE)
Every year partitions will be added for next 12 month. The table partition will be dropped every month (I have to have data from last six month so in July I could drop partition t1p1, in August - t1p2....). How many tablespaces should I create for this table and how place partitions in them to have data for last six month and use minimum space on disk?
I was thinking about one tablespace for whole table because space of each dropped partition will be reused, what do you think about that?
Is the tablespace actually off-line when doing a user-managed hot backup? I know the data blocks are copied into a redo stream but I am not sure if that means it(tablespace) is actually on-line or off-line.

I'm having a problem with grouping sets over dictionary views.
10g output:
SQL> select
2 -- 10g results
3 segment_name,
4 round(sum(bytes/1024/1024),2) mb
5 from dba_segments
[Code]...
ERROR at line 10: ORA-03001: unimplemented feature
Elapsed: 00:00:00.12
The query is fine over a non-dictionary table however (My actual code isnt against dual, but this makes it generic, the error is consistent)
11g output
SQL> select
2 -- 11g results
3 segment_name,
4 round(sum(bytes/1024/1024),2) mb
5 from dba_segments
[Code]....
ERROR at line 8: ORA-00904: : invalid identifier
Different error and that syntax, as far as I can tell, is sound - error message be damned.
An example of a query working on both versions is
select
employee_id,
sum(salary)
from
employees
group by grouping sets ((employee_id),null)
;
Am I missing something? Does grouping sets not work over the dictionary views?
Edit: Added version tags over the code to make it easier to read
