PL/SQL :: Tablespace Allocated / Used / Free And % - Used By Every Schema Level
Mar 11, 2013
One tablespace used in two different schemas ,in this case how much space used,free space and persentage of used in each schema level.
Example: USERS tablespace used in two different schemas HR,SCOTT. in this suche case to find the total size of tablespace, used and free space of each schema level.I used the below query not giving appropriate result.
SELECT TABLESPACE_NAME,
OWNER, round(SUM(BYTES/1024/1024),2) "Used Space in MB"
FROM DBA_SEGMENTS
where tablespace_name not in ('SYSTEM','TEMP','SYSAUX','EXAMPLE','UNDOTBS1')
group by tablespace_name,owner
order by tablespace_name
Our production DB version is 11.2.0.1 and we do use DBArtisian. Everyday morning we check table space usage using that tool and it generates the below listed query. It used to run in 15 secs. But since one week it is running for 5/6/8 mins. I have updated the statistics on sys objects and tuning advisor created the execution plan. So, now it is running in 2 mins. Nothing has been changed in the DB configuration. I see the same query running in secs in dev environment. understand what might be the issue and how could I improve the performance of this query.
SELECT SUB.TABLESPACE_NAME, SUB.STATUS, SUB.EXTENT_MANAGEMENT, SUB.SEGMENT_SPACE_MANAGEMENT, SUB.TOTAL_SPACE_MB, SUB.USED_SPACE_MB, SUB.FREE_SPACE_MB, SUB.PERCENT_FREE_SPACE, SUB.CONTENTS, SUB.TABLESPACE_GROUP, CASE WHEN SUB.TABLESPACE_NAME = P.VALUE AND SUB.CONTENTS = 'UNDO' THEN 'YES' ELSE 'NO' END

I was learning some recovery part in my home laptop. Database is in Archivelog, flashback mode. All of sudden, i deleted it from OS level with out taking backup of it.
When i tried to open database, it failed to start. Database is in mount mode.while trying to open, it gives message -
ORA-01157: cannot identify/lock data file 1 - see DBWR trace file ORA-01110: data file 1: 'F:ORACLEPRODUCT10.2.0ORADATADBSYSTEM01.DBF'
I tried to create on file named "UNDOTBS01.DBF" but oracle is not recognizing it.
I have created trigger on database level in system schema. While i am creating new tables in system schema, trigger logged the entry but when i am creating table in scott schema it is not working for that.
CREATE OR REPLACE TRIGGER ddltrigger AFTER DDL ON DATABASE BEGIN INSERT INTO aud_log (user_name, ddl_date, ddl_type, object_type, owner, object_name ) VALUES (ora_login_user, SYSDATE, ora_sysevent, ora_dict_obj_type, ora_dict_obj_owner, ora_dict_obj_name ); END;
Our Testing DB is running in No archive log mode. I did a schema level import by dropping the existing user that contain tables, recreate the user and finished the import. Now they want the old tables back.Is there is any way to recover the old tables?
what is the data dictionary table to find out the default table space and temporary table space for a user.Let say i have a user called 'Pointers'.How to find out the default table space and temporary table space for this.I have checked in 'dict' table but no luck.
SELECT * FROM dict WHERE table_name LIKE '%TABLESPACE%'
I'm having issues with things disappearing from my database. I know what you are thinking, OK Crazy things don't just disappear. The only thing I can think of that could be a possible problem is the way the oracle server is set up. (For the record, I don't agree with this set up. I was like this when I started with the company and they don't want to change it "because it works").
We currently have 90 + schemas on the server all in one tablespace. So the server has a data tablespace and an index tablespace. Every schema shares those tablespaces. It gets much worse that this but I'm not going to get into it.
Do you think that this set up would cause things to become missing?
I have created my schema in SYSTEM schema way back accidentally by forgetting to specify the database tablespace. There is about 60 objects (tables, indexes, functions etc) and 6MB Of data.
What would be the best way migrate the schema to the tablespace I planned to put it into? .
Below is the output of Tom Kytes script show_space, which I have run on one of my indexes.
Unformatted Blocks ..................... 0 FS1 Blocks (0-25) ..................... 0 FS2 Blocks (25-50) ..................... 102,936 FS3 Blocks (50-75) ..................... 0 FS4 Blocks (75-100)..................... 0 Full Blocks ..................... 28,615,887 Total Blocks............................ 28,748,800 Total Bytes............................. 235,510,169,600 Total MBytes............................ 224,600 Unused Blocks........................... 0 Unused Bytes............................ 0 Last Used Ext FileId.................... 233 Last Used Ext BlockId................... 1,574,409 Last Used Block......................... 12,800 PL/SQL procedure successfully completed.
If I look at the unformatted blocks its zero, which tells me that data is being placed into every block (pretty well compressed). But what I don't understand is why there are 102,936 blocks that are only 25-50% full? I would have expected to see some blocks that in the75%-100% full range as this index was recently dropped and rebuilt 2 months ago.
This index is on a partitioned tabled, where the 90th day and higher partitions are dropped daily.
Here is the layout of the index
CREATE INDEX T1.FEAT_IDX ON T1.FEAT (R_SEQ, SYSTEM_NAME, FEATURE, FLAG) NOLOGGING TABLESPACE TB1
[Code] .........

I'm trying to generate a statistic, that shows me a weekly or monthly report over the traffic on a tablespace or a schema. Until now, I've worked with the
HIST_VIEW dba_hist_tbspc_space_usage
(I mean there is also one nearly called so for schema), but that view show me only the grow of a tablespace in a timeline of 1 week.
But that would not be the hole traffic. Because SELECT statements will nothing do on the grow of the tablespace but it generates traffic. In that case it wouldn't be so important, if it is more tablespace or schema sided because at this database each tablespace has it's own schema and timeline would be nice if it is weekly or monthly.
I have schema level export for user SAMPLE1(Default tablespace USERS) on oracle 9.2.0.1 production database. I want to import into another 9i database on another server, so do i nneed to Create SAMPLE1 user and USERS tablespace in new database again.
when we ran SELECT statement against CUBE, we got below wait event: resmgr: cpu quantum.Further, we checked below 2 parameters :
NAME VALUE ------------------------- -------------------------------------------------- resource_limit TRUE resource_manager_plan SCHEDULER[0x12B943C]:DEFAULT_MAINTENANCE_PLAN [code]....
It has been found that these sessions did not get enough CPU to process the request. how to find out how many CPU has been allocated to this database ?

I want to write a sql query which will fetch the data from manual_temp_master and manual_temp_detl.But from manual_temp_detl table, Price_bkt_cds columns should be displayed as columns. Like the should look like as below:
what is the difference on DBMS_STATS for table level and partition level , which will provide the best optimizer . If the table xxxx is partitioned from 1 to 10 ,then running gather stats on table xxxx as whole table level or partition level which will provide best result on the performance.

Can you take an incremental backup level 1 or level 0 without archivelogs?
syntax would bebackup as compressed backupset cummulative level 1 database.
The reason I ask is because when I run backup as compressed backupset cummulative level 1 database plus archivelogs # it runs fine, but when I run backup as compressed backupset cummulative level 1 database it just hangs.
between statement level or row level trigger, which trigger will execute first.We have BEFORE_UPDATE_ROWLEVEL_TRIGGER and BEFORE_ UPDATE_ STATEMENT LEVEL_TRIGGER triggers on table product.
I have a business need to have a db function that would construct and return a (temporary) CLOB value.
here is its sample code:
create or replace package PKG_TEST_CLOB as function FN_TEST_TEMP_CLOB return clob;
[code]....
when this function is invoked from a SQL Statement...
*** select PKG_TEST_CLOB.FN_TEST_TEMP_CLOB from dual; ***
... the NOCACHE_LOBS counter in V$TEMPORARY_LOBS for my session is incremented by 1
when this function is invoked via a PL/SQL block...
*** declare l_clob clob; begin select PKG_TEST_CLOB.FN_TEST_TEMP_CLOB into l_clob from dual; end; / declare
[code]....
... the counter doesn't budge
In real life, this function will be used by a Reporting Tool (cognos) via SQL. I tested it, and it seems that it is allocating a new temp lob segment with every invocation.
