Traffic to Oracle Instance from (any client)

Hi
I am working in oracle 10g R2/Solaris.
I have couple of questions to gurus.
1.Traffic to DB
I want to find what is traffic to my oracle database on last day or (specific time frame)
That is (no of request received and no of request responded may be trend can be for every 5 mins) Is it possible? if so, how.
Instance Timestamp     # of Request     # of response
abc     30-05-2013 00:00     453     45
abc     30-05-2013 00:05     118     12
abc     30-05-2013 00:10     721     72
abc     30-05-2013 00:15     897     90
abc     30-05-2013 00:20     372     37
abc     30-05-2013 00:25     353     352. Most expensive SQL that is consuming more time (on a specific timeframe say for example on last day)
Thanks

Access Oracle 9i from a Client Application without Oracle Client Install.

Is it possible to access an Oracle Database from a Client Application without having an oracle Client Installation ?
I want to write a program that connect to an Oracle Server. I use Borland C++. But my Programs only works with having the Client Oracle Software installed on the Client. Is there any way to realise this ?

The way that 99% of the people that want to do this manage is to write Java code that connects to the database via JDBC, using Oracle's thin JDBC driver.
If you absolutely have to use C++, you can purchase thin ODBC drivers from third parties (DataDirect for example) that will connect to the database without the Oracle client. I'm not aware of any thin, free ODBC drivers.

Portal GUI and reports are not opening correctly once opened from any client explorer

HI,
If I try to open portal admin page and discoverer to view reports using browser installed on same unix server (Using Xwindow) , everything is opening perfect. while If I open from any client machine the browser doesn't show things correctly , not able to click links ,not able to open drop down list...

Ok so I saw this issue recently and it was effecting one user for specific documents.
The fix was not very technical but try and see if this fixes it:
Click View -- Arrange ll -- Select Cascade
This should bring up the document correctly
Maximize the working Sheet
Minimize the same Sheet
Then maximize the Sheet again
Then close the Sheet
Close excel
Open up the file

Connect to 10g oracle server from 9i client

Hi All,
Is it possible to connect to 10g oracle server from 9i client or Should i install 10g client on my machine?
Regards,
Seena

Depend of what releases you are talking about.
The client 9iR1 has never been supported against a 10gR2 server.

How to restart Oracle instance from oracle client

I have an Oracle server 10g with DEVEL instance on AIX machine. I have an Oracle Client on Windows machine as well. I want to stop and start the instance DEV from my client using bat file. Is it possible ? Is anybody knows how to do it ?
KP>

well, right now the correct question should be : how to start database.
I am able to login as sysdba to DEVEL on AIX ( from Windows client) and shutdown it but when I try to startup it returns such a message:
ORA-12505: TNS:listener does not currently know of SID given in connect descriptor
but I am still able to tnsping my DEVEL from client ...Post listener status, its contents and entry tnsnames.ora file. Here is how I got connected shutdown and started. The process I followed:
1)Made entry in listener.ora file as I said earlier, restarted the listener
2)Made change in tnsnames.ora file
3)Connect from client shutdown and started.

How come clients have to return to the original machine to access their photos and files? Why can't they access them from any client?

When students login & upload images onto a client, they have to return to that same client. They cannot see their images if they log into another client the next day.
Currently, I created uses as Local only on a server dns of ---- .server.private. via the "internet" not VPN. (as advised by a Apple Rep phone call).
Do I change it to server HD? When I tried "Users" , they could not log into any client.
Is it a permission issue on the client?
Are they pictures stored on the Client HD or the Server HD under users home folders? When I had Snowleopard, I could create folders outside their homes and see them on the server HD. Now I cannot see any folder created "ouside" the main Doc or Pictures Folder on the SERVER HD. They can, when they log into the same client each day.
Advice?

From what westhighphoto said "When I had Snowleopard, I could create folders outside their homes and see them on the server HD" it sounds like users have been saving files outside their home directory. In that case it does not matter whether they are using full-blown Network Home Directories or Portable Home Directories (with syncing) the files will not be copied back to the server.
The users should be saving the photos inside the Photos folder inside their home directory. These will then be saved on to the server.
Note: iPhoto if still being used should default to this.

Network Help - Accessing my Oracle Database from a client

Hi,
I am new to installing and managing oracle databases so please bare with me if i seem a bit dense.
I have installed Oracle 10g to a windows 2003 server and created a database instance called appConfig sid: appConfi
I have successfully connected to the database and created objects via sql using sql+ on the server that the database install resides on. The server is part of a small network (one application server and a client). I am trying to get sqlplus on the application server (which is a client as far as oracle is concerned) to connect to the database via sql plus.
I have set up the tnsnames.ora file on the client and can successfully tnsping the database name "appConfi" from the command prompt indicating that the tnsnames.ora file is successfully providing the correct host details.
When i attempt to logon to the database via sqlplus using the same credentials I used on the actual database server i get the following error message from sqlplus:
ORA-12154: TNS:could not resolve the connect identifier specified
This is my tnsnames.ora file that resides on the client and it is exactly the same as the one on the database server:
APPCONFI =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.2.2)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = appConfig)
Any ideas?? I need to set this up for my final year project at university and it is giving me a headache.

I did manually create my tnsnames.ora file on the client, i have now deleted it and went through net manager > Service Name wizard and got the following message when i attempted to test it:
Initializing first test to use userid: scott, password: tiger
Attempting to connect using userid: scott
The test did not succeed.
ORA-12514: TNS:listener does not currently know of service requested in connect descriptor
There may be an error in the fields entered,
or the server may not be ready for a connection.
I entered the service name as appConfi
Any more ideas??
It looks like the server is not resolving the name so I have deleted my listner file on the server and recreated it using the wizard and it is now as follows:
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = C:\oracle\product\10.2.0\db_1)
(PROGRAM = extproc)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = projcav1)(PORT = 1521))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
still i get the same result??? Is it just me !!!!!

Fred=================================
A couple of important points.
First, the listener is a server side only process. It's entire purpose in life is to receive requests for connections to databases and set up those connections. Once the connection is established, the listener is out of the picture. It creates the connection. It doesn't sustain the connection. One listener, with the default name of LISTENER, running from one oracle home, listening on a single port, will serve multiple database instances of multiple versions running from multiple homes. It is an unnecessary complexity to try to have multiple listeners or to name the listener as if it belongs to a particular database. That would be like the telephone company building a separate switchboard for each customer.
Additional notes on the listener: One listener is capable of listening on multiple ports. But please notice that it is the listener using these ports, not the database instance. You can't bind a specific listener port to a specific db instance. Similarly, one listener is capable of listnening on multiple IP addresses (in the case of a server with multiple NICs) But just like the port, you can't bind a specific ip address to a specific db instance.
Second, the tnsnames.ora file is a client side issue. It's purpose is for address resolution - the tns equivalent of the 'hosts' file further down the network stack. The only reason it exists on a host machine is because that machine can also run client processes.
Assume you have the following in your tnsnames.ora:
larry =
(DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = myhost)(PORT = 1521))
    (CONNECT_DATA =
      (SERVICE_NAME = curley)
)Now, when you issue a connect, say like this:
$> sqlplus scott/tiger@larrytns will look in your tnsnames.ora for an entry called 'larry'. Next, tns sends a request to (PORT = 1521) on (HOST = myhost) using (PROTOCOL = TCP), asking for a connection to (SERVICE_NAME = curley).
Where is (HOST = myhost) on the network? When the request gets passed from tns to the next layer in the network stack, the name 'myhost' will get resolved to an IP address, either via a local 'hosts' file, via DNS, or possibly other less used mechanisms. You can also hard-code the ip address (HOST = 123.456.789.101) in the tnsnames.ora.
Next, the request arrives at port 1521 on myhost. Hopefully, there is a listener on myhost configured to listen on port 1521, and that listener knows about SERVICE_NAME = curley. If so, you'll be connected.
What can go wrong?
First, there may not be an entry for 'larry' in your tnsnames. In that case you get "ORA-12154: TNS:could not resolve the connect identifier specified" No need to go looking for a problem on the host, with the listener, etc. If you can't place a telephone call because you don't know the number (can't find your telephone directory (tnsnames.ora) or can't find the party you are looking for listed in it (no entry for larry)) you don't look for problems at the telephone switchboard.
Maybe the entry for larry was found, but myhost couldn't be resolved to an IP address (say there was no entry for myhost in the local hosts file). This will result in "ORA-12545: Connect failed because target host or object does not exist"
Maybe there was an entry for myserver in the local hosts file, but it specified a bad IP address. This will result in "ORA-12545: Connect failed because target host or object does not exist"
Maybe the IP was good, but there is no listener running: "ORA-12541: TNS:no listener"
Maybe the IP was good, there is a listener at myhost, but it is listening on a different port. "ORA-12560: TNS:protocol adapter error"
Maybe the IP was good, there is a listener at myhost, it is listening on the specified port, but doesn't know about SERVICE_NAME = curley. "ORA-12514: TNS:listener does not currently know of service requested in connect descriptor"
Third: If the client is on the same machine as the db instance, it is possible to connect without referencing tnsnames and without going through the listener.
Now, when you issue a connect, say like this:
$> sqlplus scott/tigertns will attempt to establish an IPC connection to the db instance. How does it know the name of the instance? It uses the current value of the enviornment variable ORACLE_SID. So...
$> export ORACLE_SID=fred
$> sqlplus scott/tigerIt will attempt to connect to the instance known as "fred". If there is no such instance, it will, of course, fail. Also, if there is no value set for ORACLE_SID, the connect will fail.
check executing instances to get the SID

Tnsping from any client to new server fails

Hi there,
This was my first oracle 10g install and everything seemed to be working but now its not. I just installed a 10g server and added it's IP to my tnsnames.ora files on my other computers. I can ping it regularly just fine but tnsping fails. Any ideas? Our network has a subnetmask of 255.255.255.192, could that cause a problem?

Cannot connect to 10g instance from 11g client (ORA-12638)

Hi,
I don't know why I have problems when I connect from a 11g client to a 10g server. I get the error ORA-12638.
However, it works fine doing the same with a 10g client.
Can anybody tell me how to avoid this problem without having to install the 10g client ?
Thanks in advance.
Regards.

Hi, user7409638,
To understand the problem, I advice you to enable tracing and have a look at it.
As you may know, ORA-12638 is the problem with the authentication service.
It was just unable to get your credentials.
If you want me finally get the solution, please report it at my system http://1dayotn.blogspot.de/p/question-me_7.html
If you have any questions, ask.

Running statspack report remotely from a client?

Hi!
To get a statspack report I run @spreport.sql from an SQL*Plus session on the database server.
Having to go to the DB server for that sometimes is a chore and I would prefer to get a report from any client, or even from within SQL Developer.
Is there an easy way to achive this or is there a tool for that?
Obviously, the spreport.sql might differ from Oracle DB version to version, so I would either need to have a series of these reports scripts on the client and the select the right one or I would need to have some mechanisum (stored proc?) that gets to rdbms/admin on the server, executed the spreport.sql script there, read the output and return that from to the client.
Is there an easier way or anyone knows of a package that will do that?
Thanks,
Marcus

Marcus,
I don't think that I did get your question. Sorry but do you mean to say that you want a report from the client terminal , running locally over teh client only? That's what I got from this line,
Having to go to the DB server for that sometimes is a chore and I would prefer to get a report from any client, or even from within SQL Developer. Or do you want the report to be available from the server side to the client's local machine?
If you want the report to be given to you on the client side only, I am not sure that there is any way possibly there. What's the issue in fetching the report from the server though ? If one can connect to db as a valid db and o/s user, he can fetch the data as well. But its just a thought. I don't use any of the tools much so I guess, I shall just join you and see what others have to say about it.

Not able to connect to Oracle EBS from host Windows 7

Hi, I have installed oracle EBS version 12.1.1 (32 bit) on OEL ver 6.3 (32 bit). I have installed Linux on Oracle VM virtualbox ver 4.1.16.
I am having host OS as Windows 7 home on my laptop.
While setting up the Network in Oracle VM virtualbox, I have set "attached to" as 'Host Only Adapter'.
I am able to connect to oracle EBS from the client server(linux) using Firefox browser. Both the services(database, Application) are starting & stopping without any problem.
I have entered following setting in C:\Windows\System32\drivers\etc\hosts file.
192.168.56.101 linux.server

Please help in resolving the issue.
Thanks!

I am getting error as "Internet Explorer cannot display the webpage" on IE ver 9, when accessing from host machine. On Firefox (ver 12), the error is coming as "The connection has timed out. The server at linux.server is taking too long to respond."
The firewall on the server has been disabled already.

Switch instance from EE mode to SE

Is there any way to switch Oracle instance from enterprise edition to standard?
For example I have Oracle EE with mounted DB.
Can I set some parameter so that after restarting instance will crashes if DB has bitmap indexes (only EE option)?
And is there any way to disable (without restarting instance) all EE features for query processing such as bitmap index conversion or parallel query processing?
Thanks

The only way to properly convert from an Enterprise Edition database to a Standard Edition database is through an Export/Import operation. The Export/Import operation does not introduce data dictionary objects specific to the Enterprise Edition, because the SYS schema objects are not exported. Oracle recommends using the Standard Edition Export utility to export the data. After the Import in the Standard Edition database, you are only required to drop all user schemas related to Enterprise Edition features, such as the MDSYS account used with Oracle Spatial.
Below are the basic steps you need to follow to migrate your database(s).
1.Install Oracle Standard Edition in different ORACLE_HOME.
2.Backup your databases. Recommended either COLD backup or Oracle Export. If database is critical and getting downtime for consistent backup is not possible, then perform HOT backup before switching database to Oracle Standard Edition.
3.Shutdown database using 'shutdown immediate' or 'shutdown normal'
4.Set your new ORACLE_HOME and other Oracle variables appropriately. Make sure that below environment variables are pointing to new ORACLE HOME.
export ORACLE_HOME
export LIBPATH
export LD_LIBRARY_PATH
export SHLIB_PATH
export TNS_ADMIN
5.If you are using any of the below parameters, turn them off before starting database.
SYSTEMTRIG_ENABLED
JOB_QUEUE_PROCESS
6.Start database under new Oracle Home.
At this point, your database is running in Oracle Standard Edition but all the Oracle dictionary tables/packages are still in Enterprise Edition. You, also, need to migrate these objects to Standard Edition. To do that, execute following scripts after connecting to Oracle as INTERNAL or SYSDBA
$>sqlplus /nolog
SQL>connect internalOR
SQL>connect /as sysdba
SQL>@?/rdbms/admin/cataproc.sql
SQL>@?/rdbms/admin/catlog.sql
Above scripts will recreate all the SYSTEM objects used by Oracle.
If you are using Oracle RMAN Catalog in your database then you also need to upgrade RMAN Catalog. To do that, connect to RMAN and execute upgrade catalog
$rman
RMAN>connect target
RMAN>upgrade catalog;
7.Shutdown database and restart it.
8.Post Migration Steps: If you are performing any backups using RMAN or any database maintenance jobs such rebuild indexes, make sure to update your scripts appropriately.
§Oracle Standard Edition supports only one RMAN channel. Make sure to update your backup/restore scripts with one channel allocation.
§Oracle Standard Edition supports only 2GB memory allocation, make sure to adjust your memory allocation accordingly.
§Oracle Standard Edition doesn’t support index rebuild ONLINE

How to get the failover partner name from C++ client

Hi All,
I have configured the mirroring session for my application.
I want to modify the connection string with failover partner name.
Could any one please let me to know how to get the failover partner instance from C++ client dynamically.
Thanks,

(AVC) Is there Any way to prioritize traffic from wireless client (laptop in my case) to AP

Is there any way to prioritize traffic from wireless client (laptop in my case) to AP …. if i explain the issue in a broad way there is no congestion going on in wired network. When multiple users connect to real presence and all share the same AP. they get real-time output over the call BUT if someone start file-transfer over the same AP the real presence call voice/video get stuck.
I applied the AVC feature on WLC but as i tested, i think prioritization from my laptop to AP will not happen and the situation remains same.
Please share if there is any way to prioritize traffic from wireless client (Laptop) to AP only ?

Hi Vinod,
Here is the AVC & QoS interaction for upstream & downstream traffic. For downstream it is important you have configured your WLAN with correct QoS profile & 802.1p values as that play a role even though you marking traffic using AVC.
Upstream1. Packet comes with or without inner DSCP from wireless side (wireless client).2. AP will add DSCP in the CAPWAP header that is configured on WLAN (QoS based config).3. WLC will remove CAPWAP header.4. AVC module on the controller will overwrite the DSCP to the configured marked value in the AVC profile and send it out.Downstream 1. Packet comes from switch with or without inner DSCP wired side value.2. AVC module will overwrite the inner DSCP value.3. Controller will compare WLAN QoS configuration (as per 802.1p value that is actually 802.11e) with inner DSCP value that NBAR had overwritten. WLC will choose the lesser value and put it into CAPWAP header for DSCP.4. WLC will send out the packet to AP with QoS WLAN setting on the outer CAPWAP and AVC inner DSCP setting.5. AP strips the CAPWAP header and sends the packet on air with AVC DSCP setting; if AVC was not applied to an application then that application will adopt the QoS setting of the WLAN.
I am not sure which controller software version you are running. From AVC perspective, it is good if you could install latest NBAR protocol pack (4.1 for WLC 7.5.x code or 6.3 for WLC 7.6.x code) on your controller.
Here is the 7.5.x AVC deployment guide which should help you on this
http://www.cisco.com/en/US/docs/wireless/controller/technotes/7.5/AVC_dg7point5.html
Like others mentioned, it is very little you can do with respect to upstream direction as AVC kicks in only when traffic hits WLC & not at the AP level.
