PL/SQL :: Oracle RDBMS 10g R2 - SQL Performs As Expected When Trace Enabled
Aug 7, 2012
Environment:
Oracle RDBMS 10g R2.
DB OS: HP Itanium
We use Oracle EBS R12.1.2 in our company and one of the analyst reported performance with saving the configuration in Pricing module. The common fix is to gather stats on BOM_EXPLOSIONS table. Recently, when the issue occurred I collected statistics on the table. The performance didnt improve. I went ahead and decided to trace the Oracle form session using the profile 'Initialization SQL Statement - Custom" at user level.
I also monitored the session in OEM 10g grid. The analyst performed the same set of steps and the performance was normal and acceptable. Analyst tried again and performance was matching with the expectation. I cleared the trace profile and analyst tried again. This time analyst had worse performance as the original issue. The issue got fixed later part of the day on its own. This has made me curious and thought to discuss it here.
I have had similar experience with 10g and 11g, when I enable the trace on the issue cannot be reproduced and when trace is off the issue pops back up.
I am a oracle DBA with 2 and a half year experience.What I am hearing is some new tech nosql database which will take over from rdbms databases in a few years time. Is it true and can nosql used for OLTp environments.
I am installing oracle 11g under ubuntu 12.10(32bits) and getting an error 'all_no_orcl' 'ins.rdbms.mk'. It occurs when it tries to invoke the file.my laptop is 32 bits, 30.7 hd, 1.5 GB ram, 2MB cahe. The OS is installed on an external drive.
i got a problem recenly in Oracle 11g R2 RAC database . normally When I export sample user 'SCOTT' , it takes hardly one minutes .But In our RAC environment this export runs with 20to40 minutes .
Here the output : --------------------------------------------------------------- oracle@rac2 dump]$ expdp system/sys123 directory=test_dir dumpfile=scott1.dmp schemas=scott

In another machine(where I configure RAC again in Linux) , I got the same problem . I also dont find any perfect documents in metalink . My host information :

I am new to Oracle Workspace Manager. I have a trigger that fills my IDs every time i insert a record. I created the trigger before I enable the version of my table. After version was enabled in my table, I can no longer find my trigger but have these triggers instead:
OVM_DELETE_7 OVM_INSERT_7 OVM_UPDATE_7
What I wanted to do is Query the triggers that I created on my tables. Is there a way to do that without disabling the version on my table? I have too many version-enabled tables and that would be a hassle disabling the version in every table just for that query.
I used the Exchange Partition feature to swap segments between 2 tables- one Partitioned, and one Non-Partitioned. The exchange went well. However, all the data in the partitioned table has gone to the partition which stores the maxbound values.
/** actual table names changed due to client confidentiality issues */
-- Drop the 2 intermediate tables if they already exist
drop table ordered_inv_bkp cascade constraints ; drop table ordered_inv_t cascade constraints ; /**
1st create a Non-Partitioned Table from ORDERED_INV and then add the primary key and unique index(s):
*/ create table ordered_inv_bkp as select * from ordered_inv ; alter table ordered_inv_bkp add constraint ordinvb_pk primary key (ordinv_id) ; -- create unique index ordinv_scinv_uix on ordered_inv_bkp( SCP_ID ASC,
[code]....
-- Next, we have to create a partitioned table ORDERED_INV_T with a similar
-- structure as ORDERED_INV.
-- This is a bit tricky, and involves a pl/sql code
-- Add section to set default values for the intermediate table OL_ORDERED_INV_T
FOR crec_cols IN ( SELECT u.column_name ,u.nullable, u.data_default,u.table_name FROM USER_TAB_COLUMNS u WHERE u.table_name ='ORDERED_INV' AND u.data_default IS NOT NULL ) LOOP
[code]....
-- Next, use exchange partition for actual swipe
-- Between ordered_inv_t and ordered_inv_bkp
-- Analyze both tables : ordered_inv_t and ordered_inv_bkp
BEGIN DBMS_STATS.GATHER_TABLE_STATS(OWNNAME => 'HENRY220', TABNAME => 'ORDERED_INV_T'); DBMS_STATS.GATHER_TABLE_STATS(OWNNAME => 'HENRY220', TABNAME =>'ORDERED_INV_BKP'); END; / SET TIMING ON;
We try to upgrade the 10g to 11g oracle instance and asm instance.Below steps we r done;
1)First we are install the 11.2.0.3 database and grid infrastructure in separate home.
2)after that i try to upgrade asm instance so i drop old 10g asm localconfig cd $ORACLE10g_HOME./localconfig deletecd $ORACLE11g_HOME./localconfig add but here i can not find localconfig Note:database and grid installed without error....
3)Even we are try dbua but it run 10g dbua we are not able to run dbua for 11g
4)inventory is corrupted how to recreate inventory
5)provide the steps for upgrade 10g asm to 11g asm
if it is possible to install APEX version 3.0.1 on oracle database version 11.2.0.3? We currently have a 10g database with APEX 3.0.1 installed. Now for an upgrade project we need install the latest database version. Unfortunately we do not have enought time to migrate the APEX application. Therefore the APEX version should stay the same.
So any experiences with APEX 3.0.1 and RDBMS 11.2?(I searched for oracle documentation but couldn't find anything useful.)
I have two Oracle databases (test1- 10gr2,test2 - 11gr2) on rhel 5.5. is it possible to find which particular oracle process belongs to which home from OS level. was trying to find which db processes are consuming more resources on my host.
I have enabled the below trace event before running query on my session.
ALTER SESSION SET events = '19027 trace name context forever, level 0x1000';ALTER SESSION SET tracefile_identifier = store_trace;
Then I ran my query, and upon the finishing of the query, I ran the below to disable trace.
ALTER SESSION SET events = '19027 trace name context off, level 0x1000';
Now I checked back on the trace folder in my Oracle DB directory structure, but cannot find any file created by using the above set tracefile_identifier. I had previously run the query with "sql_trace" ON with tracefile_identifier, and successfully got the tracefile generated by using the identifier.

Is it possible to audit when a constraint is disabled, enabled or dropped? Sometimes I wonder why some constraints are missing. To make sure someone is dropping I would like to audit that action. Further, I would need to compare schemas to realize if some constraints are missing. As it names are generated automatically by oracle, how could I easily run a select to compare the constraints that does not match between schemas?
We have a non-production Oracle 10g Cluster running on Linux, with DataGuard (logical standby). From time to time, we need to refresh the schema on primary, but to do so as always caused problems with the logical standby. Our DBAs can never get it to complete successfully. They have tried a bunch of different methods (even provided from Oracle), but it does not work. e have a bunch of skip statements on the
Everytime, we need to refresh the schema, we have to build the entire database (primary and logical standby) from production RMAN backup. As you can imagine this is a very time consuming ordeal. There has got to be a way this process can be completed in a timely manner.
I was thinking of the following.... 1) shut down dataguard, log shipping 2) lock user, kill sessions, drop user from primary 3) lock user, kill sessions, drop user from logical standby 4) run impdb on production export file on primary 5) run impdb on production export file on logical standby 6) re-enable dataguard, log shipping 7) confirm logs being applied, databases in sync
We are only replicating the one schema to the logical standby. I am not clear on how redo logs would be applied to the logical standby. There are hundreds of them @ 100 mb each, so I would think if we do this independently, I could somehow sync primary and logical standby after the imports complete.
I have a problem in oracle forms. I have a block that displays five records in list item. On load, it will query two data in my table. So the list item (poplist) one and two enabled. (The default of oracle forms - List item one and two are enabled and the rest are disabled because one and two have data).
My problem was, what work around will I gonna do so that if I pressed the mouse in the third list item it will automatically enabled (for a new record) and if I pressed the list item one or two the third item will stay disable (even the fourth and fifth) because simply the user wants to update the item one or two in the list.
I have a scroll bar in my form. When i scroll the bar, one of SUBMIT buttons which is disabled gets enabled automatically. Do we have any triggers on scroll bar where i can disable the button again.
My requirement is to export Oracle table's data into an already existing excel file with Macros (.xlsm) using a procedure. I am able to write/append the data into the simple .xls file. But I am searching whether any way of appending into .xlsm file. "how can we append the data into a Macro-enabled excel file?".
I created a mv for one of the partitioned tables but on viewing the mv capabilities it still shows PCT is set to 'N'.
create materialized view MV_summary_SEC refresh fast start with sysdate nEXT SYSDATE + 1/24 enable query rewrite as [code]....
If i remove the sub query and create the mview like this,then PCT is enabled.
create materialized view MV_summary_SEC refresh fast start with sysdate nEXT SYSDATE + 1/24 enable query rewrite as select PERIOD , SUM(SUM_WEB_HITS) from summary ,date_table where PERIOD >= DATE_TABLE.CUR_DATE group by PERIOD
Is it simply because oracle doesn't support PCT if the definition contains subqueries ?
with t1 as ( select 'eff_date' param_name, 'mb256_type' param_type,'01-01-1970' param_value from dual union all select 'disc_date' param_name, 'mb256_type' param_type,'31-12-9999' param_value from dual union all select 'initial val' param_name, 'mb256_type' param_type,'30' param_value from dual) select param_name,param_type,param_value from t1;
desired output:
need output in a row in three different columns
param_value 01-01-1970 31-12-9999 30
I tried below query
SELECT * FROM ( with t1 as ( select 'eff_date' param_name, 'mb256_type' param_type,'01-01-1970' param_value from dual union all select 'disc_date' param_name, 'mb256_type' param_type,'31-12-9999' param_value from dual
I am having Oracle 9i relaese 2 on my db server. I am getting the following error every time I try to create a bitmap index:-
ORA-00439: feature not enabled: Bit-mapped indexes
I have queried the v$option table .Here the value of parameter Bit-mapped indexes is FALSE.
The result of v$version is :-

Actually when we created the database our installation was halted . so we manually created the database using Create database command.
I am having some difficulties with this trigger. It keeps giving me the error "ERROR at line 5: PL/SQL: ORA-00923: FROM keyword not found where expected" when I am not even using a SELECT before the line it says the error is on? Here is the trigger that I am attempting to create.
