Stats-pack Not Working On RAC 2 Node?
Jun 15, 2013
We have 2 node oracle 11.2.0.3 RAC database and we enabled stats-pack on the database(since its STD edition). However we found that stats pack report coming from 1st node properly but second node it show as below.

DBMS_STATS.CREATE_STATS_TABLE
DBMS_STATS.EXPORT_SCHEMA_STATS
DBMS_STATS.GATHER_TABLE_STATS
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.

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.

Consider following scenario
Schema Update Privilege on emp directly
User1 Yes
User2 No
I have created a package named pack in user1 schema which contains one procedure which updates table emp. ow i executed the following in schema user1
Grant execute on pack to user2;
I connected as user2 and executed
Create Synonym pack for user1.pack;
Note that user2 doesn't have update privileges on table emp
Tell me whether user2 can update emp through package pack

current environment
Oracle VM 2 Node RAC cluster
Oracle 11G 11.2.0.3.0
Oracle 11g rel 2 GI
on current 2 node cluster we have GI and RAC db configured Nodes: vmorarac1,vmorarac2
we shutdown vmorarac1 to clone it to vmorarac5
on new node I have changed the hostname to vmorarac5 In /etc/sysconfig/network-scripts/ifcfg-eth0 change ip to new ip and same for /etc/sysconfig/network-scripts/ifcfg-eth1 152.144.199.210,152.144.199.211
mad echanges to /etc/hosts on vmorarac1/2 for 2 new IP address assigned to vmorarac5
152.144.199.171 vmorarac1.pbi.global.pvt vmorarac1

152.144.199.184 vmorarac1-vip.pbi.global.pvt vmorarac1-vip
[Code]....
Query is is that all ok to reboot the new node to reflect changes as below and change the hostname to vmorarac2
152.144.199.210 vmorarac2.pbi.global.pvt vmorarac2
192.168.2.32 vmorarac2-priv.pbi.global.pvt vmorarac2-priv
152.144.199.211 vmorarac2-vip.pbi.global.pvt vmorarac2-vip
hostname change in /etc/sysconfig/network
On new node vmorarac5, there is alreay software for RAC DB and GUI cloned from vmorarac1
addnode.sh is used to add existing node, but as part of pre-requisite configuratoin is there any config step missing

I believe, in a multiple RAC Physical Standby nodes only one node applies the archivelogs to the standby database. How you can find which node is the APPLY NODE using a SQL query?
I know you can veiw this information by querying the standby configuration using DGMGRL but how would you find out this information from a remote client using SQLPlus/PLSQL?

I am installing Oracle 10g Clusterware in RHEL 5 Server. When i run root.sh in the second node the last step Running vipca(silent) for configuring nodeapps failed. Then i run VIPCA manually in second node and configured vip configuration successfully,but when i checked the post-checks for cluster services the Checking existence of VIP node application,Checking existence of ONS node application and Checking existence of GSD node application in second node failed. I am able to ping both the servers one another with vip name successfully and the CSS,CRS and EVM appears healthy in both nodes. 1. Does the vip configuration is proper? If no what is causing this error and how to rectify it? Find the output below

I would like get more details about single node RAC.. What is single Node RAC?..
1). just configure only one server instead of two node... same RAC installation.. cluster installation and shared disk configuration in single server itself.. in future we can add node to this ...
2). in 11gR2 having new feature Single Node RAC.. Multiple instances running on same node and configure using Cluster...
is there any advantage using single node rac(other than online upgrade to full RAC).

I'm trying to add the third node to my existing two node cluster. In fact i succeded adding the node but i have the following problem:
-when i start node 1 and 2, everything is ok, but on node 3 startup one of the other nodes fails
-this happens in any combination: start 1 and 3, everything is ok. when i start node 2, node 3 fails
The asm configuration (disks, permissions, etc) is the same on all three nodes.find below the asm and crsd log details from the failure time:

on to_char(partner_user.partner_userid,'9999')=membership.created_by
select * from oa_membership_dtl membership
join oa_partner_usr_dtl partner_user
on rtrim(ltrim(partner_user.partner_userid||' '))=rtrim(ltrim(membership.created_by))
by using first data is not fetched but 2nd is working fine , i am getting the matched records using 2nd query.
whats the diff between to_char and || symbol?

while doing stats collection weather system takes the backup of current statistics. i think we can specify stattab. but weather it takes stats backup before over writing? I got this requirement as a part of upgrade, i have already gone through export_schema_stats and import_schema stats already. Just trying all other possible options only.

I am quiet confused with the optimizer collection stats job on 11g. when run the following query i see the statistics enabled.
SQL> select client_name, status from dba_autotask_client;
CLIENT_NAME STATUS

auto optimizer stats collection ENABLED
auto space advisor ENABLED
sql tuning advisor ENABLED
I can gather statistics manually using DBMS_STATS, but there is no automated gathering of optimizer stats. how can i have system run and collect statistics on a daily bases?

I have a stored procedure running in which there is a cursor which fetches around 1500000 records and then query another table using the fetched record values.
I cannot modify the procedure as its on production. I want to know which cursor record is currently being processed by the procedure, and how many are still remaining ? How to check the cursor stats at runtime. I want to check up to which record the cursor has been fetched and how many are still remaining. I have cursor name. Is there some dynamic view to check cursor stats at runtime ?

I am trying to generate some statistics on tables connected by a dblink. I know with oracle you have table_columns which you can reference and pull some stats from.
Trying to get the column count and record counts for each table connected by a dblink. I have tried these queries below to see if I could see any db properties: (some just to try something different)
select * from "table_owner".table_column@dblink ;
select * from "status"@dblink;
select /*DRIVING_SITE(a) */ count(*) from @dblink a;
What is the best method to finding this out without spending a lot of time? I have over 30 tables which are with large record sets and would love to learn a faster approach then pulling a sample table and doing a manual count and query for each table to count the rows.

I am on 11.2 on Linux.I am looking into a performance issue. The issue is around 1 particular SQL, involving about 5 tables.I re-gathered statistics on 2 main tables in the query (out of 5 tables).
When I say re-gathered, I first did DBMS_STATS.DELETE_TABLE_STATS and then did DBMS_STATS.GATHER_TABLE_STATS.
Earlier, we had histograms on these tables, which I removed and gathered stats without generating histograms.
SQL> select table_name, num_rows, sample_size, last_analyzed from user_tables where
2 table_name in ( 'DETAIL_TABLE','MASTER_TABLE');
TABLE_NAME NUM_ROWS SAMPLE_SIZE LAST_ANALYZED
------------------------------ ---------- ----------- -------------------
MASTER_TABLE 50615338 50615338 01/10/2012 11:09:27
DETAIL_TABLE 353550440 353550440 01/10/2012 11:10:05
2 rows selected.Then ran the SQL again couple of times (actually, that SQL is in a stored procedure, which I ran couple of times).I found this wonderfull SQL on internet, which tells me when the SQL ran and which plan (identified by its hash value) it used. Using this SQL I tried to check if my SQL was run using any different plan, but it used exactly same plan it used before I re-gathered the stats. See the last analyzed time above and begin_interval_time below, same SQL has run before and after stats collection, with same plan_hash_value.
SQL> select ss.snap_id, ss.instance_number node, begin_interval_time, sql_id, plan_hash_value,
2 nvl(executions_delta,0) execs,
3 (elapsed_time_delta/decode(nvl(executions_delta,0),0,1,executions_delta))/1000000 avg_etime,
4 (buffer_gets_delta/decode(nvl(buffer_gets_delta,0),0,1,executions_delta)) avg_lio
5 from DBA_HIST_SQLSTAT S, DBA_HIST_SNAPSHOT SS
[code]....
7 rows selected.
My question is, when I re-gathered stats on 2 tables out of 5 tables in a given SQL, are the plans not flushed out of SGA? I was expecting that, at least a new plan hash value would show up front of my SQL, before and after stats collection.

We 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-06512: at "SYS.DBMS_STATS", line 20360

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?
