SERVICE_NAME and SERVICE_ID
Hi,
what is the difference between SERVICE_NAME uand SERVICE_ID ?
Many thanks.
Hi,
>>SERVICE_NAME
The SERVICE_NAMES is set in the INIT.ORA file and corresponds to (DB_NAME + DOMAIN). For example, if the DB_NAME is 'DB01' and the DOMAIN is 'COM' then, the SERVICE_NAMES will be 'DB01.COM'. Oracle (sometimes!) refers to the SERVICE NAME as the Global Database Name. The SERVICE_NAME is needed when setting up Net8. About TNSNAMES.ORA, SERVICE_NAME is the SERVICE_NAME used in the 'INIT.ORA'.
MYSERVICE =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = <SERVER>)(PORT = <PORT>))
(CONNECT_DATA =
(SERVICE_NAME = <SID>)
>>SERVICE_ID
The SID uniquely identifies an instance.
More information, you can access this link below:

Hi
What is the difference between the Service_Name and the SID and when is it used.
In the Default Listener File we have :
(ADDRESS=(PROTOCOL=ipc)(KEY=PNPKEY)))
Any comments for why/where is it used.
ThanksHi,
Serice Name represents the global database name but SID represents instance name. both of them can be used in case of single instance but in RAC envirnoment you will have to specify the SID in case of that you want to login to specific instance of the instances in the RAC envirnoment.
Here is a sample of a RAC tnsnames entry:
SEC.GROUP.LOCAL =
(DESCRIPTION =
(ENABLE=BROKEN)
(ADDRESS_LIST =
(LOAD_BALANCE=ON)
(FAILOVER=ON)
(ADDRESS = (PROTOCOL = TCP)(HOST = 193.16.1.162)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = 193.16.1.161)(PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = GRP)
(FAILOVER_MODE=
(TYPE=SELECT)
(METHOD=BASIC)
in the above example Service name (Global database name is used) if you want to be loged on a specific instance change :
1. remove the address cluase of the unneeded instances
2. add (SID=GRPx) cluase where GRPx is the SID of the needed instance.

Service_name and servers pool with priority
Hi,
Is there a way to define a service name SVC1 on 8 nodes (n1,n2 ...n8) with priority on somes nodes
and a second service name SVC2 on 4 nodes (n1,n2,n3,n4) ?
In RAC, a server can not be declare in more than one server pool, but in Exadata is-it the same ?
Thank'sHi,
you don't need to use server pools. Just create 2 services, one that is preferred on the first 4 nodes, and the other on the remaining 4 nodes. Both services should be available on all nodes. IIUC, this should do what you want to do. -
Is there a transaction to get ORACLE_SID, SERVICE_NAME and Listener PORT?
I know this information can be gotten from the Oracle DBAu2019s who set up the database, but in my big company, I even do not know who the DBAu2019s are.
My Oracle database for SAP BI 7.0 is 10.2. Is it possible to get this information using a SAP BW/BI transaction?
Thanks.> I know this information can be gotten from the Oracle DBAu2019s who set up the database, but in my big company, I even do not know who the DBAu2019s are.
In that case you really shouldn't bother where the databases are because direct SQL access should be out of discussion.
> My Oracle database for SAP BI 7.0 is 10.2. Is it possible to get this information using a SAP BW/BI transaction?
No, there isn't such transaction. Of course not.
What would it be good for?
If you need to have this information - better get in touch with the DBAs.
If the database servers are set up in a sensible way, you cannot access them anyhow.
They would be located in separate network segments, the listener would block all connection trials that don't come from the application servers .
There shouldn't be any option for you to even reach those servers without having the permission and the information from those people that are in charge of them.

i have to tried to make programs using java and oracle. if i give the values in the 'insert' statement it is getting updated in the original table in oracle but how to take the values from the text fields of java and insert into the tables in oracle. do we have any methods to convert the values into sql type. pl reply.
Here is a sample of a Java program that uses JDBC and a PreparedStatement. This particular program does a select, but you can also use this for inserts. I'm not 100% this is what you are looking for, but if it isn't just let me know. I'll help if I can.

For inserts, just replace this code:
ResultSet rs = ps.executeQuery();
while (rs.next()) {
System.out.println(rs.getInt(rs.findColumn("CNT")));
}with this code (and obviously change the Select string to an Insert String):
int rowcnt = ps.executeUpdate();Here is the whole program:
import java.sql.*;
import java.util.*;
import java.text.*;
class dbtest {
public static void main(String args[]) throws SQLException {
try {
String timeString = new String("2000-11-01 23:59:59");
SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd H:m:s");
java.util.Date date = format.parse(timeString);
Timestamp timestamp = new Timestamp(date.getTime());
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
Connection conn =
DriverManager.getConnection(
"jdbc:oracle:thin:@riker:1521:mydb",
"myusername",
"mypassword");
String sql =
"SELECT COUNT(*) CNT FROM SERVICE_ALARM "
+ "WHERE TRANS_STREAM_NODE_ID = ? "
+ "AND SERVICE_ID = ? "
+ "AND ALARM_ID = ? "
+ "AND RAISED > TO_DATE(?,'YYYY-MM-DD HH24:MI:SS')";
PreparedStatement ps = conn.prepareStatement(sql);
ps.setString(1, "ROW1");
ps.setInt(2, 1);
ps.setString(3, "ROW1");
String myDate =
timestamp.toString().substring(0, timestamp.toString().length() - 2);
System.out.println("myDate=(" + myDate + ")");
ps.setString(4, myDate);
ResultSet rs = ps.executeQuery();
while (rs.next()) {
System.out.println(rs.getInt(rs.findColumn("CNT")));
rs.close();
ps.close();
} catch (Exception e) {
System.out.println("Java Exception caught, error message=" + e.getMessage());

Use of SQL*Loader and Thin Client
I have a java application that is currently using the thin client. For portability issues, I am unable to use an OCI driver. My application also uses SQL*Loader.
My big issue is that The Thin client requires the HOST and SID for a connection.
But, for SQL*Loader to work in a client/server environment it needs to use the SERVICE_NAME and net8. Is there any way to have SQL*Loader use similar information that the thin client is using?
I know the right solution is to use the OCI drivers, but right now that is not feasible.
Thanks for any help in advance

Navigation Technologies.I assume you are using an ObjectInputStream. Without seeing your code or a snippet I can't be certain...
The JDBC spec says the following about ObjectInputStream :
"An ObjectInputStream deserializes primitive data and objects previously written using an ObjectOutputStream"
Since there was nothing written by ObjectOutputStream, ObjectInputStream has nothing to deserialize and this exception would be raised. -
Difference between Naming.lookup and Registry.lookup in RMI
Hi Folks,
I have an RMI client which tries to look up a remote object using both
Naming.lookup("//host[:port]/name OR rmi://<host_name>[:<name_service_port>]/<service_name>") and LocateRegistry.getRegistry().lookup("rmi://<host_name>[:<name_service_port>]/<service_name>").
The first one fails whereas the second one succeeds. I am in a fix as to why it is so.Is there any difference between the lookup methods provided by Naming and Registry?
The remote object was registered on the server using
LocateRegistry.createRegistry().rebind("rmi://<host_name>[:<name_service_port>]/<service_name>").I suggest you take a look at this site to understand how to ask questions.
And don't crosspost again -
Hi,
on a windows 2003 server I have Oracle 10g and Oracle 8.1.7.
When we start listener of 10g , it deos not start listener for 8.1.7 data base. For starting 8.1.7 Listener I should go to Oracle_HOME/bin of 8.1.7.
Is there any way to resolve this in order to start Listener for 8.1.7 with 10g listener ? How to include 8.1.7 Db in SID_LIST_LISTENER of 10g listener.ora?
The same we can not use SQLPLUS of 10g to connect to 8.1.7 data base . We should do this from 8.1.7ORACLE_HOME/bin. How can I change to be able to connect from every directory ?
Many thanks.Use oracle netmanager to include oracle 8i database service name in to 10g listner or else manually include 8i SID and oracle home in to 10g listner file.
Netmanager can be started by typing netmgr on command prompt
e.g
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(PROGRAM = extproc)
(SID_NAME = orcl)
(ORACLE_HOME = /u01/app/oracle/product/10.2.0/db_1)
(SID_DESC =
(GLOBAL_DBNAME = orcl)
(ORACLE_HOME = /u01/app/oracle/product/10.2.0/db_1)
(SID_NAME = ORCL)
(SID_DESC =
(GLOBAL_DBNAME = TSH1)
(ORACLE_HOME = /data2/oracle/ora8i)
(SID_NAME = TSH1)
2)
in 10g Home you need to configure tnsnames.ora for the 8i database to be connected. Put the 8i server ip and SERVICE_NAME and port in 10g tnsnames.ora file. You can find this file in $ORACLE_HOME/network/admin
TSH1 =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 172.16.21.29)(PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = tsh1)
) -
hi,
in some of our tnsnames.ora we're using service_name, and in some others, we're using sid.
what is the difference and which should be used when?
thanksThis is what Oracle doc(11.2) says for the service.
>
A logical representation of a database, which is the way a database is presented to clients. A database can be presented as multiple services and a service can be implemented as multiple database instances. The service name is a string that is the global database name, that is, a name comprising the database name and domain name, entered during installation or database creation. If you are not sure what the global database name is, then you can obtain it from the value of the SERVICE_NAMES parameter in the initialization parameter file.>
http://download.oracle.com/docs/cd/E11882_01/network.112/e10835/glossary.htm#NETRF1839
And this is what is for SID
>
A name that identifies a specific instance of a running an Oracle database earlier than release 8.1. For any database, there is at least one instance referencing the database.
For Oracle databases earlier than release 8.1, a SID is used to identify the database. The SID is included in the connect descriptor of a tnsnames.ora file and in the definition of the listener in the listener.ora file.>
http://download.oracle.com/docs/cd/E11882_01/network.112/e10835/glossary.htm#BGBIAEED
With the SID, which Sybrand has explained clearly is an older wayout,you are going to connect through the specific instance with very little options for HA solutions like Load Balancing and Fail Over. OTOH SErvice is a "logical gateway" to access the database which is not tied to any specific instance as such. Using the service name, you may connect to any instance which is configured to serve that service. The concept goes in much better conjuction with the RAC environments where we do configure any one active insntance as the preferred instance for the service where it runs in the first place and the other instance(s) as avaialable instance where it can also run in case the primary fails. So using the new syntax of serivices, the HA capabilities are available to you in a complete manner and now , almost all the things of Oracle, including scheduler, resource manager are shifting to services only and Oracle is also recommending people to use service_name parameter to use than the sid.

Difference between service name and sid
Hi All,
1. I am not able to understand the difference between Service_name and SID.
2. And I have 3 different databases(like 9i,10g,11g) with 3 instances in each(total 6), Can I configure one listener for all the databases and instances, as I have found in some documents that we need to set SID's list in listener.ora file.
Please help me in this regard,
Thanks in advanceRafi (Oracle DBA) wrote:
Hi,
If you wanted to have multiple databases specified you could nest more SID_DESC parameters in the SID_LIST. In the same way, if you wanted to listen on diffrent IP addresses you could use multiple DESCRIPTION sections in the DESCRIPTION_LIST. For example:
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.10.0.130)(PORT = 1521))
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.20.0.10)(PORT = 1522))

VBO-1508 and ORA-29902 when trying to configure XML DB
Hello,
after installing a fresh Oracle 9i EE System I would like to start using the XML DB part.
While trying to change the XML DB config using the Oracle Enterprise Manager console I always get an error (see subject).
There was alrady an Apache 2 installed and running on the server. Therfore I checked the httpd.conf in the Oracle admin dir and can find a Port 7783 and Listen 7783 directive.
Maybe the EMC still tries to connect using port 8080? If this is true, how can I change this?
Any suggestions?
Thanks in advance

Event Notifications: insufficient system memory
I'm looking for a sanity check. Service broker and Event Notifications are new to me, so it is possible I'm either abusing or incorrectly using the technology. I'm experimenting with using Event Notifications and Server Broker to log error messages. The process works pretty well as long as I don't do something stupid such as stressing the process by calling raiserror in a loop of a 100000 - twice. It processed for a while, but eventual either SQL Server terminates (sev 25) or I had to force the SQL service to stop by killing it's process via task manager. I could not connect to SQL Server or stop the service normally.
I have several general questions. I think they are good questions. Any thoughts or suggestions would be appreciated.
1) I'm looking into generating deadlock and blocking email alerts. It appears that Event Notification is the way to go since there are very few events and I can respond to the event with an email. Is there a better method to automate blocking and deadlock email alerts that include event details?
2) If I wanted to retain some history of errors for the developers, should Event Notifications be avoided if a high number of errors can be generated by a badly formed T-SQL? Avoid TRC_ERRORS_AND_WARNINGS and USER_ERROR_MESSAGE? (I could tell the developers not to be stupid, but why would that stop them if it does not stop me?)
3) Is there a way to efficiently filter a Event Notification from entering the queue before the Receive statement is called? I get some events that I throw away after receiving them. For example, perhaps I want all events from all non-system databases without having to add a notification for each single non-system database. Or I want all errors with severity 11-17 only?
4) Is there a trick to filter out events from the procedure activated by the event. I tried using raiserror to debug a procedure without thinking. The result was that the queue never was empty because the processing produced more events to process. As a result, I don't use raiserror and use a try-catch to avoid raising errors in the procedure activated.
5) I can receive one message at a time using local variables or receive a batch of messages using a local table. Is a small batch the best way even if there is memory pressure?
6) In the activated procedure I continue processing in a loop until there are no more messages. This seems to be the most efficient. Is this always the case? Should I exit the procedure after a set number (large) of messages have been received? The procedure would activate again to continue processing?
7) Is there any point to using the MAX_QUEUE_READERS setting when processing event notifications? Should it be 1?
8) I currently get the next conversation group id and process its messages within a transaction. Is this a bad idea with event notifications? Should I just call Receive and get the next batch? I don't really care if I lose some messages if things are going badly. Should I avoid wrapping the receive in a transaction?
9) I could run a trace that starts with SQL Server; however, I think my only choice is to log to a file. Is there a way to trace to a table using SQLTrace without running profiler? I would like to automate the process and have the data in a table so that it can be easily queried and parsed for each database/team.
10) Is there a way to fix my process and handle 100000 messages a minute? Is there a way to skip messages when it gets to busy? Can the query generating the messages get throttled - perhaps along with the query designer - before the server gets into trouble? Query the memory used by a queue and drop/create the queue with a delay if there is an issue?
I'm using a single CPU test machine with only 1 GB and 2 GB pagefile and a single disk. OS: Windows 2003 R2 SP2. SQL: 9.0.3054 and on 9.0.3228 (update package 6 just came out today). I could add memory, but I think that would just permit me to queue more message before running into trouble.
I'll add code shortly - length limit.Here is the activation procedure to "receive" the messages. I won't bother including the scripts for the two tables. The 50000 char limit is trouble.

end loop;put it's not save , please helpHi Phil,
You can add in the in-built MRU update process that will do this for you. When you add a process, select Data Manipulation then Multi Row Update, then follow the prompts to link it to your table.
In your code snippet, htmldb_application.g_f01 refers to the first column in your form (even if this is hidden). Normally this is the Primary Key for the table on which the form is based. htmldb_application.g_f02 refers to the second column and so on, although you can assign any number from 1 to 50 to each field when you create the sql statement.
The replace() function is used because some of the fields will contain %null% which needs to be converted to null before updating the table.

Not able to connect with Oracle server through VBScript without DSN
Hi
I have both Oracle9i and Oracle10g clients installed with local system.
I am able to connect to Oracle Database 11g Enterprise edition server though sqlplus through command prompt and also through AQT without any error.
As the server has lots of database ,whenever I connect to a particular database through sqlplus from command prompt,I connect as below
C:>sqlplus username/password@service_name
and it gets connected without any error.
When I am trying to connect the same database through VB Script,I am getting ORA-12560 TNS:Protocol Adaptor Error.
Below is the connection string I am using:
Database_String = "SERVER=xxxx.vvvn.Com;Driver={Oracle in OraHome92};DATABASE=service_name;user id=userid; password=passowrd"
I have installed a Oracle10g server in my local system and tried to connect the same way and I was successfully ,but its not working when the server is running remotely.
Does it make any difference with the version of driver being used ?Should I need to modify my connection string anyway.
Please help me as to identify the issue.Thank you very much in advance.
Regards
