View 1 Replies View Relatedquick 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.

Actually in our environment , sysadmins are upgrading java versions on Unix (HP & Solaris) Machines and they have asked the query whether oracle database uses Java or not?
If it uses then all the databases need to be shut down for their planned activities and if not no need to shutdown the databases.
i am getting this error during expdp ORA-01555 -snapshot too old
1. i increased undo_retention i.e 50000
2. i execute expdp during late night when almost zero user is online so no commit from any other session.
3. we have a table having BLOB data type field in a table which is 500 GB in size.complete DB size is 700 GB
where and why this error exists.if corruption of BLOB so how to check that etc. the same error is occurring in three of our data centres during expdp.
would want to check which tables located in which datafiles.
Tried with this command:
select B.FILE_NAME from dba_segments a, dba_data_files b
where a.header_file=b.file_ID and segment_name='TABLE_NAME'
Seems like it only shows 1 datafile. Some tables are large and i suppose it's resided in more than 1 datafile.
which data dictionary view would you query to see the free extents in a tablespace.
i use dba_free_space;
SQL> select tablespace_name,sum(bytes),sum(blocks) from dba_free_space where
tablespace_name = 'SYSTEM' GROUP BY TABLESPACE_NAME;
TABLESPACE_NAME SUM(BYTES) SUM(BLOCKS)
------------------------------ ---------- -----------
SYSTEM 9830400 1200

I was trying to delete the database in the test server. When i was deleting listener was already stopped, i continued deleting using dbca, it shown me some alert that datafiles cant be deleted because system could't find database, since listner was stopped so only service was deleted(the one showing in the windows administrator toolsservicesOracleServiceTEST).
All the datafile parameter files are still there. How can i delete the datafiles and parameter files belongs to that database or how to create the deleted service, so that i will start the listener and do the complete deleting of the database.

I am trying to find the unix process for one of my application in the database but I am unable to view the same. To simulate, I did the following.
1. My database runs on different server.
2. I invoked "sqlplus" from another unix box to login to the database.
3. I found that the process id (ps -ef |grep sqlplus).
4. When I execute the below mentioned query it does not display the process id that I am looking for. But the osuser, username, program and machine details are correct. How can I know the process details from the database?

View 3 Replies View RelatedI'm trying to connect a oracle client application on the client machine to a remote oracle server on the server machine but i get a connection fail.
On the server machine I configured oracle server in the following way:
Installed oracle server. Created a database "DB_Test" with the database configuration assistant Created a LISTNER with the Oracle NET Manager with the following parameter:
Protocol: TCP/IP HOST: server pc hostname (ENZOVAIO) or server machine address ip (192.168.0.71) in the network lan Port Number: 1521 Created "dbtest" service with the Oracle NET Manager with with the following parameter:
Service Name: "dbtest" Protocol: TCP/IP HOST: server pc hostname (ENZOVAIO) or server machine address ip (192.168.0.71) in the network lan Port Number: 1521
All services on the server machine are running and I opened port number (1521) in the router. On the client machine I installed SQL PLUS and SQL Developer.
With SQL Plus as by the official documentation I have entered the following command:
CONNECT username/password@[//]host[:port][/service_name]. In my case is:
CONNECT SYSTEM/oracledb@//ENZOVAIO:1521/testdb.
With SQL Developer I have entered the same parameter.
But with both SQLPlus and SQL Developer the connection fails.
