When we want to gather schema statistics which method we should follow and why ?
exec dbms_utility.compile_schema('SHIKHAR');
or
BEGIN
SYS.DBMS_STATS.GATHER_SCHEMA_STATS (
OwnName => 'JACK'

During STATS gather running for the table, unknowingly i deleted the old stats using EXEC DBMS_STATS.DELETE_TABLE_STATS. I would like to know will it affect the stats gather job currently running for the table and whether my stats will be gathered successfully.

View 10 Replies View RelatedWe are running 11g (11.2.0.3)We have a "working table" that is empty at the beginning of the day.Then we start adding rows (insert) with a key column called STATE with a value of 100.At the same time, there are other apps that pickup data in state 100 , process that data and change that state to 200 or 300.There is also another app that pickup data in state 200 , process that data and change that state to 300 or 400.
So in summary, the data on that table is at the beginning empty, then all the rows are in state 100, they slowly move to different states (200, 300, etc) and by the end of the day, they are all in 400.
My question is what would be the best way to collect stats on this table?
I was thinking to create an hourly job to collect stats on that table:
exec dbms_stats.gather_table_stats (
ownname => 'SCOTT',
tabname => 'WORK_T
I've just installed an Oracle 11.2.0.1.0 64 bit server on my windows 7 machine in order to play around while using attempting to run
exec dbms_stats.gather_table_stats('eii','v2x4e')
I get the following:
ORA-20000: Unable to analyze TABLE "EII"."V2X4E", insufficient privileges or does not exist
ORA-06512: at "SYS.DBMS_STATS", line 20327
ORA-06512: at "SYS.DBMS_STATS", line 20360
ORA-06512: at line 1
My initial google searches indicate that I need the select any table and analyze any privileges. I don't think that can be right/appropriate - but I've granted them anyway to no avail.
Select * from user_tables
returns tables in the System and sysaux tablespaces, but not my own schema/tablespace?
what privilege is required to run dbms_stats package for gathering table and schema statistics.

I revoke all the privileges from JACK user but still i am able to gather stats for a table.what privilege is require to gather stats.
I've got to collect statistics by DBMS_STAT. For the first time, the spcreate.sql is to be called, however, it returned one error following:
If this script is automatically called from spcreate (which is the supported method), all STATSPACK segments will be created in the PERFSTAT user's default tablespace.

SQL> select owner, synonym_name

Then, I checked again after dropping schema PERFSTAT:

What's the STATS@SNAPSHOT_ID synonym? Can I remove it from PUBLIC owner and recreate?
Quote:Oracle collects new statistics when enough of the data (about 10%) has changed.I read the above statement in the oracle documentation that Oracle collects new statistics when enough of the data (about 10%) has changed every day during 10 pm to 6am .
But still i see some object statistics are stale and empty.Do i need to collect statistics for these objects manually ? and would like to know why these objects statistics were not collected during maintenance window ?
Using below script i run stats gather job..But LAST_ANALYZED column is not updated for the table.. Why it was not updated.. My DB version is 11.1.0.7.0

A single master schema where many developers are accessing. all share same password.
now i would like to trace all the changes made by each users. so i create a individual users for all and grant permission to access that schema.do i have a possibility of auditing the changes did by each user for that particular schema
single schema setup or multiple schema setups for an application development. Which option is recommended and pros and cons of these methods?

View 3 Replies View Relatedefficient & fast method for Audit trailing tables in a Schema for any insert /update /deletes for a table. I do not want to use db triggers because of performance issues.
presently we have as system which does audit trail as below:
1. If a user changes a column value for a table ( update/insert/delete) then we call a db package and pass the parameters like table name,col name,user, operation (ins/update/delete),old value, new value,date modified,user modified etc
2. the called package will insert a record in the audit trail table with the parameters passed
3. The audit trail table is used for report generation .
I have several databases that i've recently upgraded from 9i to 11g. With all of them, the automatic stats gathering process has worked just fine every night during the maintenance window.
However, i have this other database that i created and it seems that the only stats being gathered are on the sys and system schemas and not the actual schema that holds all of our tables.
I did some searching, but i'm not sure i was using the right search terms, because i came up empty.

I have 10 important schemas in my database,and i want to give only select privileges from SCHEMA PRODUSER to other 10 schemas. And also want that the new objects that are created in PRODUSER after granting the privileges are also have select privileges. Is it possible that i should directly grant select privileges from one schema to other without granting via individual objects(script to grant individual privileges from individual objects)

we have a two different databases at different locations and on different servers, like one in our company with SID='A' and remote database with SID='B', We have recently implemented new module in database 'A' by creating lots of tables, functions, indexes, sequences, synonyms etc and now we need to install this on 'B' but the problem is we have not documented which tables we created, first we need to create a DB link between these two and then we need a tool to compare what are all the tables that we need to create in database 'B' , is there a tool for doing all this.

I have used the above to get a copy of schema stats and gather new stats for specific tables into a STATS TABLE in my personal schema. What I want to do now is use this stats table to generate plans for queries where I believe stats are off. Is it even possible? To be clear, I do not want to import stats because this replaces the stats currently there. I just want to point the CBO to my stats table for generating plans.
there was a session parameter I could set to tell oracle to use my stats table when generating plans, or an explain plan clause I could use or a DBMS_XPLAN paramter I could provide that would tell these tools to use my stats table when generating a plan, or even some way to tell autotrace. But I have found none of this.

View 3 Replies View RelatedI want to get clear with one thing yesterday i installed oracle9i and dev 2000 to my client.
when they run one report they got stuck with pl/sql compilation errorrep-1247
when i checked that report in the report builder, in the query they are using some other table which is not belongs to that schema,then I give that schema.tablename and compiled, but this is coming for other reports also, then only i came to know that they are acceessin other schema also, how can i sort this out.
can i fix this by givin full access privilige or what privilige can i give to get full access of other schema table.
how can i check in the old database what are all the roles and privileges given to this user,
difference between a user and schema on Oracle.By difference, I do not mean what is a user and what is a schema.
I understand that if we create a user, the schema gets created by default for that user. Does that mean that we cannot create a user/schema alone.
What if I just want to create a user and grant him some read access on an existing schema or just want to create a schema.
I have created different scripts to monitor growth planning of the database my idea was generate a simple output file to a directory and create a report and send it as mail thru mail server. but the client requested me to create new schema and population all the stats i have collected into the tables in this schema .
