HOW CAN GENERATE SEQUENCE/SERIAL NUMBER OF SAME CATEGORY EMPLOYEES AND INSERT INTO TABLE NEMP?
Here is my situation.
1. I generate file_name through a function.
2. File name like File_DD_MM_YY_FLXXX.
3. Now this FLXXX is the filenumber. It will be 1 for the 1st run of the day and for each of the new run it will be +1. Again next day it will start from 1.
So right now I am using a sequence and resetting it at 12 AM to 0. Is it a good approach to solve the scenario?
11gr2, HP-UX, 64-bit. From last one week, we are seeing tremendous increase in archive-log growth. Its comes almost around 110GB per a day (db size=600g). I don't think its usual.Alertlog is clean and we don't see any alerts. Remedy app is built on this db and its creating tables on fly with LOB columns and indexes on them. As a first step. shall I disable logging for indexes on LOB columns ?

I have written a Java class which generate and place the XML file in a particular location. This the java class is loaded into Oracle using the loadjava command. When I call the sql java procedure java classn will be called and the XML file is generating.
But my problem is with xml header i.e in the header it is getting as
<?xml version = '1.0' encoding = 'UTF-8'?>
Where as I am generating the xml file from by just java call instead from Oracle the header is as follows
<?xml version="1.0" encoding="UTF-8" ?>
I am thinking that this could be reason with different jar using Oracle side.
I have a question on export dump file generation.

By changing the parameter to 2 min, what could be the impact on database?

We had our production database hosted on Oracle 9.2.0. Few months back we have migrated it to Oracle 10.2.0.4.0. After Migration I have noticed that redo generation has become very very high. In earlier case no. of log files generating in production hours were around 30 where as after migration it become around 200 files per day. I have run statspack report on this database. Report is saying that db block change & disk write is become very high. Parameter timed_statistics has also been set to FALSE. Even then there is not any reduction on no. of log file generation. I had used import export for upgrading the databases.
View 13 Replies View RelatedI am running a database version 11.2.0.3 on a RHEL 5.3 system.A nightly ETL job drops all tables of a certain schema and recreates them as part of this job.After recreation of the tables statistics are generated to make query execution faster.
The ETL job uses following statement to gather the statistics for each table: EXEC dbms_stats.gather_table_stats('SCHEMA', 'TABLE', cascade => TRUE); As we had performance issues on the database I analysed the statistics and found that there were no histograms collected for the tables although the data are skewed.
Therefore I searched a database wide parameter where I can change the default statistic collection method from 'SIZE AUTO' to 'SIZE SKEWONLY'. I found following method: DBMS_STATS.SET_DATABASE_PREFS () I used this package to set the database prefs to 'size skewonly' and recreated the statistics. All was fine. exec DBMS_STATS.SET_DATABASE_PREFS (pname=>'METHOD_OPT', pvalue=>'FOR ALL COLUMNS SIZE SKEWONLY');But one day later after the ETL job we had the same issue again. After a further analyse I saw that there were no histograms generated on the tables. It seems that the drop and recreation of the tables make the system wiede default parameter useless.
how to set system wide optimizer defaults even after dropping and recreating a table?
I have created 5 materialize view with REFRESH FORCE option.
REFRESH is done with every 10 min.
My destination database is MySQL.
DBlink is created in ORACLE 10g
Materialize view is created using DBLINK.
Since refresh materialize view done with every 15 min, my Redo generate gone on toss.System is generating 1 redo file for 1 min.

Is there any setting/option/or solution to reduce high redo generation.
