The other day, we had a query run amok in our 2-node production cluster. The 3 temp files for the temp tablespace were all still set to autoextend unlimited, something I forgot to change after a recent upgrade. I created 3 new temp files and tried to delete the huge temp files. I did this from sqlplus with this commad:
ALTER TABLESPACE PSTEMP DROP TEMPFILE '+DATA/isis/tempfile/pstemp.291.641298061';
The huge files are still in ASM storage. dba_temp_files reports that the status of them is AVAILABLE but they have no RELATIVE_FNO. Grid Control reports their status as OFFLINE and their size as 0. They are actually close to 20 GB each.
I tested the above alter statement in two test instances, also RACed with ASM storage and the temp files were successfully deleted, but they were much smaller in size. At this point, how do I delete the three 20GB files from ASM in our production instance? Why didn't they delete the first time?
As I was observing the space issues on my db server. I found that there is lots of Trm and Trc file which is being created very much frequently. Due to this its consuming lots of space even the size of each files is not more than 1Mb.
For cleaning I am deleting all the trm and trc files mannully using DEL command Os level. How can i schedule the purging of trm and trc files.
I performed a switchover test of my Exadata databases last night. Both databases are running 11.2.0.2 (BP7) on top of GI of the same version.I'm using Data Guard Broker to administer the Data Guard configuration.
I have, as you'd expect, the standby_file_management set to AUTO, so any file changes/additions/deletions that are made on Primary should be applied to Standby also.And they have been. Until last night.
When I had switched over to running Primary on the Standby site, I got this error message:
Tue Jun 04 22:27:12 2013 Errors in file /u01/app/oracle/diag/rdbms/exdw1pdg/exdw1pdg1/trace/exdw1pdg1_ora_26630.trc: ORA-25153: Temporary Tablespace is Empty
I checked and my two temp tablespaces existed, but had no files in them. These files are 200Gb and 448Gb in size, so you'd think you'd notice them going missing. This wasn't by any means the first time we switched over (and, yes, I did create temp files for Standby when I built it and first switched over)
We've switched over to Standby multiple times and even ran a whole day's processing against it and haven't seen this. Ultimately, it wasn't a big deal, because I just created a tempfile for each of the tablespaces and off we went.Nothing in MOS seems to mention something like this. Basically, it looks like the switchover process decided to eat my tempfiles but keep my temp tablespace defintion. Odd.
About the concept of quorum failgroup ORACLE says:QUORUM disks, or disks in quorum failure groups, cannot contain any database files,the Oracle Cluster Registry (OCR), or dynamic volumes. However, QUORUM diskscan contain the voting file for Cluster Synchronization Services (CSS). Oracle ASMuses quorum disks or disks in quorum failure groups for voting files wheneverpossible.
To sum up, i think the different between a regular failgroup and a quorum failgroup is a quorum failgroup can only contain vote files and a regular one can contains multiple kinds of files.So i didn't see any advantage to place voting files on a quorum failgroup than on a regular one. Why Oracle introduce the concept of quorum failgroup?
I have an oracle autoback of controlfile and spfile. I am trying to restore the production database using this backup, into a new server with a different directory structure.
I have completed the following steps in the restore process.
1. Creating a pfile from spfile
2. Changing the the location of cdump, udump, bdump and the control files ( there are three )
3. Then creating a spfile from this pfile
I am stuck on the next step where to rename all the datafiles and tempfile and restore the database. Following is what I did.
After mounting the database in RMAN, tried to run the following.
RMAN> run 2> { 3> allocate channel c1 device type disk 4> ; 5> @/home/oracle/rman_scripts/newloc.rman 6> SET NEWNAME FOR DATAFILE 1 TO '/u02/oradata/dorian/system01.dbf'; 7> SET NEWNAME FOR DATAFILE 2 TO '/u02/oradata/dorian/undotbs01.dbf'; 8> SET NEWNAME FOR DATAFILE 3 TO '/u02/oradata/dorian/sysaux01.dbf'; 9> SET NEWNAME FOR DATAFILE 4 TO '/u02/oradata/dorian/users01.dbf';
[code]....
I am getting the following error message.

I am working in a bank as an system consultant, i have a SAN Storage Area and oracle as below.
SAN 1
This interface includes the DATA FILES of the oracle tablespace
SAN 2
SAN1 Mirrors the DATA FILES of the oracle tablespace to SAN 2
1. Can i rely on real time data recovery from SAN2 ? 2. if SAN1 (Data Files are currupted) will the SAN2 Data Files will be currupted as well. 3. If the SAN2 is currupted then what Oracle Features can be used to have uncurrupted data.
One of our customer have problem with following sql statement:
SELECT c.table_name, c.column_name FROM user_tab_columns c, user_tables t WHERE c.table_name = t.table_name AND c.data_type IN ('CLOB', 'BLOB');
During execution it takes all the TEMP tablespace size(8GB).
I gather system stats (dbms_stats.gather_dictionary_stats(estimate_percent=>null)) but it doesn't resolve problem.Above sql statement works fine with RULE hint but I want to know what is the reason of problem with temporary tablespace.
I am trying to run on Oracle report via Oracle Application Concurrent job. Concurrent job is completing normal but I don't get anything on print out page. In log file of this request I see message 'MSG-01003: Errors =>ORA-01652: unable to extend temp segment by 128 in tablespace TEMP'. I almost doubled the TEMP tablespace in size but still I am not able to get rid of this error message.

Error Message : ORA-01652:unable to extend temp segment by 128 in tablespace TEMP
this huge report that uses inline views. I keep getting the following error message when running the script through toad. I was thinking about using the USE_HASH hints. The sql optimizer we use is very buggy in Toad. I'm using oracle database version 10.2.0.3.
I have a TEMP tablespace with autoextend on next 10M and maxsize 5120M, now my tablespace is 99.98% full. Am getting ORA-1652: unable to extend temp segment by 128 in tablespace temp error, can i use the method to increase the maxsize value to 10240M.
My organisation is currently discussing different storage options for the database storage. Our production database is nearly 2TB and we do not want to continue with the existing NetApp storage (we use a 2 node RAC running 11.2.02 with nfs filesystem from NetApp filer).
We were looking at different options and came across Nimble Storage, they are very fast growing company aiming mid-range storage customers. The initial talks and demonstration looked very promising in terms of IO performance (they claim 40,000 - 60,000 IOPs for their CS400 series Nimble Storage array) and other options they are providing but we understand that majority of their customers are using it for VDI and other infrastructures.
They have demonstrated us using if for Oracle database with ASM storage over iSCSI LUNs. We are yet to do the POCs and benchmarking.
Has anyone come across Nimble Storage for running Oracle databases?
I have written make files that compile .pc files in unix. This was for several projects that use an oralib source code directory.Just running proc on one target .pc file works fine on unix. I am trying to use proc - Oracle 10.2.0 - in windows and I keep getting:
Quote:unable to open include file #include <stdio.h> and other C library headers.
I am doing all development under cygwin, this way I can write a makefile just like under unix instead of using nmake.All C library headers are in /usr/include When I run proc on Solaris as that:
proc program.pc No problems, and I do get program.c.
However in windows I get the previous error message. I have tried to do proc include=/user/include program.pc and proc include=/user/include parse=full program.pc but I still get the same error message.
db and dev 10g rel2 ,suppose that i have a table with a lot of duplicate rows ,what i need is to delete the duplicates and retain one row of these duplicates . likecolumn -- with those values...how to delete two (hi's) and retain the third , ?it is all applied to all the duplicate values in the column.
Trying to delete duplicate rows from a table. The problem is, they aren't exactly duplicate rows. Let me explain.
I am migrating data from a Oracle 8.1.7 db to a 10.2.1 db. In the older db, this certain table does not have a PK/Unique Index, but in the new db there is a unique index. The fields that the index is unique on are:
In the old db, when I run this query I get 1229 rows. With a count of 2 each.
select SUBSCR_NO, SUBSCR_NO_RESETS, EXTERNAL_ID, EXTERNAL_ID_TYPE, ACTIVE_DATE, count(*) from customer_id_equip_map group by SUBSCR_NO, SUBSCR_NO_RESETS, EXTERNAL_ID, EXTERNAL_ID_TYPE, ACTIVE_DATE having count(*)>1;
They are duplicates on those fields, but they are not totally duplicate rows because there is a field called is_current that has 0 in one row and has 1 in the other. What I need to do, is delete the 1229 rows with is_current=0.
First one : ----------------- 1)Created a backup table from the Fragmented table (This table is a partitioned one). 2)Analyzed this table. 3)DROP the Fragmented table 4)Inserted the backuped up data from backup table to the Re-created table. 5)Analyze this table.
Second method ------------------- 1) Create a backup table newly, with PCTFREE =0 2) Inserted the data from Fragmented table ( This is a partitioned table) to backup table 3) Analyzed this table. 4) Truncate Fragmented table 4) Did Exchange partition of Fragmented table with Backup table.
The second method is not found to be removing the Fragmentation. Before the fragmentation was 28% after Second method the fragmentation is still the same. While the first method the fragmentation reduced to 16%.
Query used to find Fragmentation. select table_name, round((blocks*8),2) "table size kb", round((num_rows*avg_row_len/1024),2) "actual data in table kb", round((blocks*8),2)- round((num_rows*avg_row_len/1024),2) "wasted space kb",
What I want to do is add is this logic: If Predirection is null, then no space between streetno & streetname. Same for postdirection and unitname. (for example, if both postdirection and unitname are null, there are no spaces between streettype and the comma before propertycity)
Also, when unitname is not null, I want to add the string "Unit " prior to the returned value in unitname.
One of my clients need to remove three(of four) CPU to comply the licensing agreement with Oracle.
To avoid problems and also to list the possible problems that removing the CPU can bring, I wish to make a survey of the possible impacts, especially in performance, that removal can cause.
I am working with Oracle 10G, and have been working on setting up little pl/sql checks to make sure that the data that is imported is in the correct format.
The wall I have hit is removing illegal characters from the data I import. I have started to set something up where the string for a certain column must be be made of only there characters:
"ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz-" (note that there is a - besides just letters) and I may want to add some other characters later. So basically the script will drop or replace any character not found in my definitions with "", thus removing the illegal character and joining the previous and next characters.
I thought for sure there would be a script posted somewhere online that did this but I can't find it and my syntax skills are lacking.
INSERT INTO NODE_LVL VALUES('TBL_APL','TBL_AFL'); INSERT INTO NODE_LVL VALUES('TBL_APP','TBL_ACS'); INSERT INTO NODE_LVL VALUES('TBL_ADD','TBL_ADW'); INSERT INTO NODE_LVL VALUES('TBL_ADP','TBL_ADV'); INSERT INTO NODE_LVL VALUES('TBL_AOP','TBL_AOV'); [code]......
Table 'TBL_APP' is having 2 parent nodes i.e 'TBL_AOV' and 'TBL_ADV' SELECT * FROM node_lvl WHERE child_node = 'TBL_APP';
At level 5 there is duplicate nodes i.e 'TBL_APP' and 'TBL_ACS' as parent_node and child_node respectively.
SELECT PARENT_NODE, CHILD_NODE, LEVEL FROM NODE_LVL START WITH PARENT_NODE = 'TBL_ACF' CONNECT BY PRIOR CHILD_NODE = PARENT_NODE;
I want to suppress such duplicates. So I added DISTINCT
SELECT DISTINCT PARENT_NODE, CHILD_NODE, LEVEL FROM NODE_LVL START WITH PARENT_NODE = 'TBL_ACF' CONNECT BY PRIOR CHILD_NODE = PARENT_NODE;
BUT requirement is to maintain the same order (of hierarchy) as it was before adding DISTINCT.
I've a table in data warehouse production with data which is partitioned by RANGE, sub-partitioned by HASH.Later we realized that subpartitioned are not needed as volume is less.
I tried below approah in DEV DB:
1. create table ABC_BAK as select * from ABC;
2. dbms_metadata.get_ddl('TABLE','ABC')
3. Removed the subpartitions details from the output of step 2 and prepared the script of create table without subpartitions

I am trying to remove duplicates from a table with over 10million records. Below query is working fine but it doesnt contain any COMMIT interval. I have to commit after every 20k or 30k records deletion for which IF loop is necessary.
Query:
delete from customer where rowid in (select rowid from (select rowid, row_number() over (partition by custnbr order by custnbr) dup from customer) where dup > 1);
