It always used to be that Automatic Memory Management and Linux huge pages were incompatible: you had to use one or the other. But 11.2.0.2 has new parameter, USE_LARGE_PAGES. This isn't documented apart from a few articles on metalink, but Googling it suggests that if it is on TRUE (the default) or ONLY then I can use AMM with huge pages.

We have Oracle 10g(10.2.0.4) RAC on AIX 5.3, there are 3 RAC instances on each node.From Oct 9th, we found one of the instance in node 1 generated a large size trace files in udump. The largest size of the trace file take up 3G. But there's only about 15G $ORACLE_BASE direcotry. After some time, we should delete some trace files for releasing the space.
Here is a part of alert log when this issue happen:
Sun Oct 9 23:18:15 2011

I checked with some trace files, I found all these files contains a huge info of processes.
We are facing one issue on one of the database. The database is generating large trace files(14000) from last two days. That consumes around 15G space on the disk. And the content of the trace files is not having any meaningful message to debug:
cat /apps/oracle/admin/fs90uat/bdump/fs90uat_p050_23966.trc

How to change db timezone parameter. My application team has asked me to change the db timzone parameter by following sql.
ALTER database SET TIME_ZONE = '+10:00';
Is this way is the correct one , and do we have any impact on database and does it require a db bounce.

I have a simple question about database sessions. The value of parameter "sessions" is set to 500 and the users connect to database through an application server(Jboss). There are more than 500 users connect to the database through application.

quick check on a hidden parameter? I need to know the default value and possible values for _serial_direct_read on various releases, I have only 11.2.0.3 available right now and I'ld like to know this for 11.2.x.x 11.1.x.x, and 10.2.x.x.
Below is the query that will show what it is currently which (unless you've changed it) will be the default: auto for my 11.2.0.3. Then to see the options, try to set it to something wrong, my options are false/true/never/auto/always. I think false/true were the only choices for 10.2 and are maintained only for compatibility. But I can't rememebnr 11.1.

I am getting the following error while starting database.
ORA-32004:obsolete and/or deprecated parameter(s) specified
How oracle deals with the setting of init.ora parameter compatible.
e.g. we have
DB Version=10.2.0.4
compatible=10.2.0
what is the possible leak for us ? Is there any description about the features changed in 10.2 up to 10.2.0.4 in all steps - so that we can check out which functions we do not have.
I have a question about spfile.
SQL> SELECT COUNT(*) FROM v$parameter WHERE value IS NOT NULL;
COUNT(*)
----------
246
SQL> SELECT COUNT(*) FROM v$spparameter WHERE value IS NOT NULL;
COUNT(*)
----------
20
v$parameter displays information about the initialization parameters that are currently in effect for the session,but v$spparameter displays information about the contents of the spfile.I want to know why the count of parameters whose values are not null in v$parameter is greater.where are they from? My initialization parameter file is spfile.
i try to startup a database, and get that obsolete/deprecated parameter specified(ORA-32004: obsolete and/or deprecated parameter(s) specified)so i try to reset the parameter, but it seems it is already reset(not in spfile), so maybe this is in memory. SO now i try to reset with scope = memory or both, it gives this error(ORA-32029: resetting with SCOPE=MEMORY or SCOPE=BOTH is currently not supported).
what to do, because now i cannot reset with scope = memory and in spfile it is not there but still it comes in deprecated parameter.
We have two databases running on 10.2.0.4 and 9.2.0.8. Both are having the same unpartitioned table of size 80G. I am exporting the table on 10g by using parallel=8 and dumpfile with %U option. That took around 4 hours to export the table.
And on 9.2.0.8, i am exporting using below parameters, taking around 5 hours.
buffer=2000000
recordlength=64000
options i can try to speed up the export in both versions.
I am considering all of the capabilities and benefits of using Data Pump for exporting and importing extremely large data files. Would like to know if importing to tape is possible? If so, would the data be accessible if needed later?

For M1, R1 and F1 I have set print object on All Pages and base printing on Enclosing Object. After running the report, output is only one page and consists of 7 rows. But as per the query it should have fetched 21 rows.
When I have changed print object on property to First Page, it output is 2 pages and consists of all 21 records.So, why print object on All Pages generating only one page while print object on First Page generating 2 pages?

View 2 Replies View RelatedI have an application that it will have over 200 pages. Each page will have a sidebar region with a number of lists, around 8-10 items. The lists references all pages in the app. Then, if I create a new menu list , I have to include this new list in all pages, it's painful. It's posible to have shared regions between pages like the shortcuts for messages in the user interface elements?
In this way, I will create an unique element including all lists that will be shared through all pages. This will greatly facilitate the work!I'm using Apex 4.1.
