Checking the health of Oracle database

How to make sure that the Oracle database Server is running at any given time. Is there any way I can send the small data pockets to cross check it is up and running. I can always try to connect to Oracle database server and if it fails I know it is not working. I am looking for any other approach from Oracle guru’s.
Oracle 10g R 2 onwards.
Thank you,

How to check the version of oracle

Hi,
Did anyone know the command to check the version of oracle db?
Thanks
daron

also as a normal user (non-dba) if you want to know then during login to the database using sql*plus you get the following.

Checking the size of Oracle XE Database

Hi,
I installed oracle 10g express edition on a Linux machine couple of weeks ago.
Installation was successful oracle is running fine. Now I am concious about the limitation of 4 GB data size in XE.
DBConsole is not running, i am working on it. But want to know the existing DB size from sql.
Kindly let me know the query that can give me the exact size of database.
I will be very thankful.
Regards, Imran

Hi,
select sum(bytes)/1024/1024 from dba_data_files;
select sum(bytes)/1024/1024 from dba_SegmentsThe first query would give you total space allocated to your database.
The second query would give you total space used by database objects.

Error while checking the status of Oracle Cluster ware

Hi
I was trying to install the database using dbca after setting up the grid and database software on LINUX x86-64 RHEL 5.7 machine. The database software version is 11.2.0.3. It throwing the error regarding the connectivity of clusterware. So I checked the status of clusterware.

=======================
I see in the above log that saying ASM instance is down and failed to open +DATA .
But the asm instance up and running
SQL> select instance_name,status from v$instance;
INSTANCE_NAME STATUS
+ASM1            STARTED
And we havent created any disk named DATA before the installation. We have created only below two disks
SQL> select name,header_status from v$asm_disk;
NAME HEADER_STATUS
ASM_DATA MEMBER
FLASH_RECOVERY MEMBER
But I am seeing a diskgroup in the v$asm_diskgroup which we havent created.
SQL> select name,state from v$asm_diskgroup;
NAME STATE
DATA MOUNTED
Ya this is a second time installtion. In the first installtion we created the asmdisk as DATA. But later everything (RAW device ) was formatted and this new disks has been created and installtion again started
[root@SFV9699 bin]# oracleasm listdisks
ASM_DATA
FLASH_RECOVERY
Seems like its trying to read the old disk DATA.
we have done asmscanning too with oracleasm scan disks. but no use.
Where I can remove the old entry of DATA disk.
It would be a great if a quick response get.
Thanks
SHIYAS M

The permission looks fine. If it was permission issue then y it is trying to read the DATA disk which I havent created this time at all ( But created in the first installation).

How to check the datfiles from oracle SQL Developer(enterprise Manager)

hi,
Iam using Oracle SQL Developer as enterprise manager in my local pc.I want to check the size of datafiles using this enterprise manager.could u pls help me out..
Thanks in advance ,
R.Ratheesh

What?
Sql developer is not enterprise manager.
Size of datafiles? Read the documention, and read the concepts and administration manuals for your release.
I am not going to provide links, because you have not given your database version number and secondly if you found this forum you can find the docs.
But I will give you a clue....DBA_DATA_FILES...

How can I change the hostname after Oracle Database XE is installed?

I currently have XE installed and working on my ubuntu machine.
When I change the hostname of my machine, oracle database no longer connects and says "ORA-12505, TNS:listener does not currently know of SID given in connect descriptor".
Can anyone tell me how I can change the hostname of my machine and keep oracle database working correctly?
Thanks

Stopping, reconfig, starting the instance is one way, although that is somewhat like using petrol to kill ants.
The database instance pretty much does not care about the hostname setting. But the listener does- the installer finds the hostname and uses that in the setup bits.
As posted somewhere here, when using the 1521 default listener port, the listener.ora config file can just be moved out of the way. Another potential fix is setting the HOST=0.0.0.0 for the IPv4 "any IP" address setting, or setting it to the correct hostname. Or HOST= can be set to IPv4 address. For IPv6, have to use HOST=<hostname> and it must resolve, can't HOST=... an IPv6 address.
To move the listener file, stop the listener first. To change a HOST=... setting, also stop the listener first.
lsnrctl stop
mv $ORACLE_HOME/network/admin/listener.ora $ORACLE_HOME/network/admin/listener.bk0
# or
vi $ORACLE_HOME/network/admin/listener.ora
# change HOST=<whatever> to the correct value, or 0.0.0.0
lsnrctl start
sqlplus /nolog
conn system
... password ... Connected.
alter system register;
exit
# start the lsnr
lsnrctl start
# check the status, services
lsnrctl stat
lsnrctl serv
If the host has a wireless (or another NIC) that one does not want to offer up remote connections on, the 0.0.0.0 is not a good way to go either

Please help, urgent! How to hold the connection to oracle database

I used java to connect Oracle database using thin driver. But I found out the connection will be closed very soon if I did not make any request of query. I query the database like after 1 mins without doing anything, my application will dead for about 2 mins, then everything become normal again.
How can I hold the connection or is there any other solution? thank you!

Duffy is, as usual, correct. If you have a single-user environment, then holding onto a connection is probably okay (not desirable but also not pernicious). However, once you have more than one user, you will want to use a connection pool. Jakarta Commons (jakarta.apache.org) has an open source pool that is reliable.
But the fact that you are having additional problems makes me believe you are missing a few fundamental concepts, such as transactions. Even if the connection dropped, you should be able to reconnect without issue (granted, with some additional latency). The only time it would pose an issue (above and beyond the ones mentioned above and in previous replies) is if you are not managing your transactions properly.
In short, take some tutorials on JDBC, DataSource, connection pools and transaction management.

Is Oracle Application Express the same of Oracle Database Express Edition (

Hi,
perhaps a silly question.
I've tried to download Oracle Application Express. Before of installing it, I've noticed that looking at the About the Create Application Manual it looks like the Application Builder that I already use with the web-based page for Oracle Database 10g XE (Express Edition). But thus is Oracle Application Express the same of using Application Builder of Oracle Database 10g XE? To me it seems so, but I'd like to be sure of that
Thanks!

oracle database XE 10g include APEX installed, version 2.... i don't remember exactly
Oracle database sinde 11g includes APEX installed too
Yes, APEX have a tab with application builder, there you create applications, but the version is very old, install Oracle DB XE 11g or upgrade APEX

How Can I Check the Health of the Time Machine Snapshots?

Hi. The last time I used Time Machine to restore to a fresh install of Mountain Lion, it had an error, I had to manually copy the folders and files in my home folder as well as XCode and bookmarks for Safari.
Is there an app that can check if the Time Machine snapshot will work when you need to restore it to a fresh install of Mountain Lion? Could it also check the backup disk for surface errors? My backup drive that uses Time Machine is fine.
Thank you in advance.
God bless.

Unfortunately, you cannot do diagnostics on a Time Capsule. Data on a Time Capsule are not stored directly to the drive. Data are stored in a sparsebundle disk image. If the disk image goes bad, then you can try to copy it to a regular hard drive so you can try repairing the disk image or you erase the Time Capsule.
You really don't need to check hard drives from time to time. If there are errors on the drive you will know about them before you have time to fix the drive. And, if the errors are fixable usually that doesn't happen using Disk Utility.
File errors are very rare no matter how often you use a HDD. There is no research to support your hypothesis.
To protect against hard drive failure (unrelated to file errors) is best avoided by making multiple backups. You cannot have too many backups. Given your concern for your files this will help you a lot more than running diagnostice tests on one hard drive. I would also recommend you not use Time Machine because its reliability is markedly less than most recommended backup utilities such as these. Furthermore, you can clone any drive using Disk Utility's Restore feature.
Suggested Backup Software
1. Carbon Copy Cloner
2. Get Backup
3. Deja Vu
4. SuperDuper!
5. Synk Pro
6. Tri-Backup
Others may be found at VersionTracker or MacUpdate.
Clone using Restore Option of Disk Utility
1. Open Disk Utility in the Utilities folder.
2. Select the destination volume from the left side list.
3. Click on the Restore tab in the DU main window.
4. Select the destination volume from the left side list and drag
it to the Destination entry field.
5. Select the source volume from the left side list and drag it to
the Source entry field.
6. Double-check you got it right, then click on the Restore button.
Destination means the drive used for backup. Source means the drive you are backing up.
