JDBC URL to connect to Standby Database

Could somebody please post the details of configuring a JDBC String in an app server (JBOSS) to connect to Standby database.

Hi,
The type, multiplicity or redundancy of the datasource connection pool can be independent of your JPA application beyond configuring global parameters. I would expect that JBoss can be setup to pool or cluster multiple JTA datasources to appear as one single pool as other servers are able to - I have not looked into this myself specifically on JBoss but you should check out Oracle RAC support - which is supported on WebLogic.
thank you

JDBC-ODBC-Bridge connection to SQL Database

Hi guys
I have a problem. I've made a little game which I want to put on my website. It has a highscore-list which I want to connect to my web host's database server to get the current list.
I tried this with JDBC and got it to work locally but when I uploaded it to my site it didn't work. I contacted my web host's technical support who told me that their server didn't have the JDBC driver and that I should use ODBC instead. I did lots of reading and found out about this JDBC-ODBC-Bridge. I have since been trying to implement this into my program but hasn't been successful.
In my original JDBC connection I used
private String url = "jdbc:mysql://" + host + "/" + mydatabase;
Class.forName("com.mysql.jdbc.Driver");
Connection connection = DriverManager.getConnection(url, username, password);Now I'm trying
private String url = "jdbc:odbc://" + host + "/" + database;
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection connection = DriverManager.getConnection(url, username, password);But, at least when trying it locally, I get the error
java.sql.SQLException: [Microsoft][ODBC Driver Manager] Data source name is too long.

Data Guard Broker connecting to standby database fails

Hello everybody
I checked lots of pages but I'm not able to find a solution für my problem. I already set up a primary and a standby database (prim = ALPHA1 / standby = ALPHA2).
After enabling my dgmgrl configuration I got two errors:
DGM-17016: failed to retrieve status for database "alpha2"
ORA-16664: unable to receive the result from a database
The dg log from ALPHA1 says:
06/04/2013 16:06:57
Site alpha2 returned ORA-16664.
Data Guard Broker Status Summary:
Type Name Severity Status
Configuration alphadgb Warning ORA-16607
Primary Database alpha1 Success ORA-00000
Physical Standby Database alpha2 Error ORA-16664
While the dg log from ALPHA2 (standby) says:
06/04/2013 16:43:28
SPFILE is missing value for property 'LogArchiveFormat' with sid='ALPHA2'
Warning: Property 'LogArchiveFormat' has inconsistent values:METADATA='arch_ALPHA2_%S_%t_%r.arc', SPFILE='(missing)', DATABASE='arch_ALPHA2_%S_%t_%r.arc'
Failed to connect to remote database alpha1. Error is ORA-12514
Failed to send message to site alpha1. Error code is ORA-12514.
How can I solve this issue? Every type of tnsping is successfull. The sqlplus login from the primary to the standby database works, the other way round works too! Therefore the tnsnames and listener data seems to be correct.

As the listener are configured ALPHA1 (prim) should be on port 1521 while ALPHA2 (stby) should work on 1522. In the configuration of DGMGRL only appears port 1521 (look at StaticConnectIdentifier). Is this maybe the reason of the networking problems with DG Broker? How can I fix this?

Connect to Standby database

Hi ..
I set up oracle 11g Active DR. (prod db with 1 standby db(READ-ONLY) ) Seems the system working fine. But i can't connect to StandbyDB from SQL-Navigator (can connect to PROD). What can be the reason ?
It shows this when i try to connect from navigator,
ORA-01034: ORACLE not available
ORA-27101: shared memory realm does not exist
Linux-x86_64 Error: 2: No such file or directory
Note :- I can connect to both DB's from sqlplus
Regards
Visi

Hello;
Example here :
http://www.itsarva.com/ittopicsblog/?p=296
Did you start the Database ( standby correctly )
Startup mount
recover managed standby database using current logfile disconnect;
alter database recover managed standby database cancel;
alter database open read only;
alter database recover managed standby database using current logfile disconnect;
Select open_mode from v$database;v$database should show "READ ONLY WITH APPLY"

JDBC Url for connecting SQL Server Alias name

Hi All,
I am having a SqlServer Databse Instance for that we have created "alias name".
i am unable to connect to that particular alias name.
please can any one though light on this plz.
Edited by: mahesh512 on Jun 17, 2009 6:48 PM

If i am geussing right, you mean that you have created a TNS Name for your Database Server.
If you are accessing it from your DB Client via the TNS name, maybe the CLient is configured to contact a TNS Server to retrieve the IP if the server.
Your JDBC Driver does not do that. Either use the IP of the DB Server or provide a Source for the Driver to look up the IP via the TNS Name.
How this is accomplished deplends on your Database.

Wrong SID in JDBC URL

Hi all,
I'm developing a java program in OAF context to generate a pdf from a xdo data template and template. this is already working, there is only one issue.
The DataProcessor needs a connection, therefore I've specified hardcoded a JDBC URL.
Connection conn = DriverManager.getConnection("jdbc:oracle:thin:apps/apps@(DE.............");
and then pass conn to the DataProcessor.
dataprocess.setConnection(conn);
But i want to get rid of this hardcoded connection.
So I did the following:
OAApplicationModuleImpl am = (OAApplicationModuleImpl)pageContext.getRootApplicationModule();
String JDBCURL = am.getOADBTransaction().getConnectionMetadata().getJdbcURL();
System.out.println(JDBCURL");
as result a wrong connectionstring: ....com)(PORT=1533)))(CONNECT_DATA=(SID=1533)))
he takes for SID the port number....
questions I have:
- the way I work is correct?
- where does he gets his jdbc url from? becuase I already checked my database in jdev and it works (with correct SID) and also my dbc file is correct...
Thanks in advance!
Stijn

Stijn ,
You can get connection from OADBTransactionImpl in AM.Here is the sample code:
import oracle.apps.fnd.framework.server.OADBTransaction;
import oracle.apps.fnd.framework.server.OADBTransactionImpl;
import oracle.jdbc.driver.OracleConnection;
OADBTransactionImpl oadbtransactionimpl = (OADBTransactionImpl)getOADBTransaction();
OracleConnection conn = (OracleConnection)oadbtransactionimpl.getJdbcConnection();

Connecting to a database over the internet

Hello ,
Ok heres an interesting question -
I would like to have an applet running on my browser which needs to connect to a central server over the internet, which in turn will need to connect to a database and query some results. These results will be stored as flat files within the server.
At the moment, I have a URL that connects to the database via the
internet and that is working. However I don't think my applet on my browser will be able to create a flat file on that server direclty.
Could some one please tell me how to go about this problem?
Shalini

Yes, put a servlet in between the applet and database. Let the servlet interace with the database on the applet's behalf and write that file on the server side.

How to connect to a database thro JavaScript

How do I connect to a database(Say Microsoft Access), through Javascript.
-Thanx in Advance
Harini

JavaScript is something entirely different than Java.
If you really want to program with JavaScript, you are in the wrong place here. The forums here are about Java, not JavaScript. So, find some other forum on the Internet which is about JavaScript.
If you are programming in Java, you'll need to learn how to use the JDBC API to connect to a database. See the tutorial.

Standby Database for Oracle 8.1.7 Std Ed

Hi, I am using Oracle 8.1.7 std ed with W2K Adv Server. Both primary host and remote host using the same version of oracle and OS.
So far both oracle path are identical and the standby folder is same with primary and I don't think I need to add the db_name_convert and log_name_convert into my standby parameter file.
I have make a consistent backup from primary to standby and also create the standby control file from primary. However, I am having the problem on setting up the tnsnames.ora and listener.ora for both primary and standby? Can someone here give me the sample on configure those ora file? Say example
Host Name (Primary) : PRMY
DB_NAME (Primary) : PRMY
SID (Primary) : PRMY
Instance (Primary) : PRMY
Host Name (Primary) : STBY
DB_NAME : PRMY
SID (Primary) : STBY
Instance (Primary) : STBY.
This error message is once i am going to connect the standby database via SQL*Plus using sys/change_on_install@STBY, error ORA-12154: TNS:could not resolve service name displayed. However, I managed to login follow by set oracle_sid=STBY and connect as sysdba.

Execute DBMS_SERVICE in standby database

Hi all.
I have a 2 nodes RAC with 10.2.0.4.0 and 1 physical standby in red hat.
I create a trigger to start services in standby in case of switchover. I do a switchover and create the services but...
when i go back and execute a switchover again i have services started in Primary and Standby. !!!
I need to stop, drop, kill services in standby because some connections wants to connect to standby database...
execute dbms_service in standby and I have this error.
SQL> exec dbms_service.stop_service('OSAPP3_GMP.bancocredicoop.coop');
BEGIN dbms_service.stop_service('OSAPP3_GMP.bancocredicoop.coop'); END;
ERROR at line 1:
ORA-06550: line 1, column 7:
PLS-00201: identifier 'DBMS_SERVICE.STOP_SERVICE' must be declared
ORA-06550: line 1, column 7:
PL/SQL: Statement ignored
I don't know if i make a mistake in execution of procedure or I can't execute this procedure in standby database.
There is another way to stop service in standby??
Thanks and sorry by my english.

I used to use role change triggers to start services, but there were always problems.
Much better to use Dataguard Broker and have the services managed by CRS. When you switchover with Dataguard Broker it will tell CRS to stop the service on the new standby and start on the new primary.

Standby Database Switchover Question

I have a Primary and a physical standby database. I have tested switchover and failover to a point. I can't get my client applications to navigate to the "new" primary DB after switchover or failover. I assume it may be something to do with my tnsnames.ora and listener.ora files in my configuration. I will place the contents of the files below.
I was expecting to be able to add the failover syntax to my client tnsnames file and things would be fine. Unfortunately, clinet apps don't failover to "new" Primary ("old" standby DB) when testing failovers; Additionally, when testing switchovers, the client apps try to connect to the "new" standby DB ("old" Primary) instead of the "new" Primary DB.
I was hoping someone might see a syntactical error that is preventing a transparent application failover.
Thanks.
Jim

Hi another way can be configuring client tnsname files to support failover:
EXAMPLE=
(description=
(address_list=
(load_balance=off)
(failover=on)
(address=(protocol=tcp)(host=X)(port=1521))
(address=(protocol=tcp)(host=Y)(port=1521)))
(connect_data=(service_name=XXX)))
if the listener on host X (primary db) fails, client tries to connect the standby database on host Y.

MANAGING A STANDBY DATABASE-CRITICAL

Hi All,
I had a primary database version 10.2.0.3 which i upgraded to 10.2.0.4. While upgrading the database
i turned off archiving.
After i upgraded the database and brought it up and the listener i started getting errors of
missing archive logs at the standby site.
My standby database is 10.2.0.3.
My question is
1) As i had turned archiving off at the primary site there is a gap in the archive numbers at the primary itself.

I am getting errors that the standby is not in snyc with primary
when i ran query
SQL> SELECT PROCESS, STATUS, THREAD#, SEQUENCE#, BLOCK#, BLOCKS
2 FROM V$MANAGED_STANDBY;
on standby database
it says i am missing sequence # 29351 which is due to the fact that there is no sequence like that on
my primary itself.
How should i resolve this gap.
Also is it a good idea to upgrade the oracle home on my standbysite to 10.2.0.4 as i have upgraded
my primary

Hello,
Like I said no easy way out of this situation. First option sync both usign RMAN and section option setup from the scratch (that's might not be possbile).
You can also find similar steps under oracle documentation serach for resolving gaps manually/
Here are the steps for first option, study it and make changes to according to your needs
1. On the standby database, stop the managed recovery process
SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE CANCEL;
2. On the standby database, find the SCN which will be used for the incremental backup at the primary database:
SQL> SELECT CURRENT_SCN FROM V$DATABASE;
This will used in the rman backup command at step 2.
3. In RMAN, connect to the primary database and create an incremental backup from the
SCN derived in the previous step:
RMAN> BACKUP INCREMENTAL FROM SCN <SCN from previous step>
DATABASE FORMAT '/tmp/ForStandby_%U' tag 'FORSTANDBY';
You must create this incremental backup on disk for it to be useful. When you move
the incremental backup to the standby database, you must catalog it at the
standby as described in Oracle Database Backup and Recovery Advanced User's
Guide. Backups on tape cannot be cataloged.
4. Transfer all backup sets created on the primary system to the standby system (note that there may be
more than one backup file created). For example:
SCP /tmp/ForStandby_* standby:/tmp
5. Connect to the standby database as the RMAN target, and catalog all incremental backup pieces:
RMAN> CATALOG START WITH '/tmp/ForStandby';
6. Recover the standby database with the cataloged incremental backup:
RMAN> RECOVER DATABASE NOREDO;
7. In RMAN, connect to the primary database and create a standby control file backup:
RMAN> BACKUP CURRENT CONTROLFILE FOR STANDBY FORMAT '/tmp/ForStandbyCTRL.bck';
8. Copy the standby control file backup to the standby system. For example:
SCP /tmp/ForStandbyCTRL.bck standby:/tmp
9. Shut down the standby database and startup nomount:
RMAN> SHUTDOWN;
RMAN> STARTUP NOMOUNT;
10. In RMAN, connect to standby database and restore the standby control file:
RMAN> RESTORE STANDBY CONTROLFILE FROM '/tmp/ForStandbyCTRL.bck';
11. Shut down the standby database and startup mount:
RMAN> SHUTDOWN;
RMAN> STARTUP MOUNT;
12. If the primary and standby database data file directories are identical, skip to step
13. If the primary and standby database data file directories are different,
then in RMAN, connect to the standby database, catalog the standby data files,
and switch the standby database to use the just-cataloged data files. For
example:
RMAN> CATALOG START WITH '+DATA_1/CHICAGO/DATAFILE/';
RMAN> SWITCH DATABASE TO COPY;
13. If the primary and standby database redo log directories are identical, skip to step 14. Otherwise, on the standby database, use an OS
utility or the asmcmd utility (if it is an ASM-managed database) to remove all
online and standby redo logs from the standby directories and ensure that the
LOG_FILE_NAME_CONVERT parameter is properly defined to translate log directory
paths. For example, LOG_FILE_NAME_CONVERT='/BOSTON/','/CHICAGO/'.
14. On the standby database, clear all standby redo log groups (there may be more than
3):
SQL> ALTER DATABASE CLEAR LOGFILE GROUP 1;
SQL> ALTER DATABASE CLEAR LOGFILE GROUP 2;
SQL> ALTER DATABASE CLEAR LOGFILE GROUP 3;
15. If you have flashback enabled:
On the standby database, restart Flashback Database:
SQL> ALTER DATABASE FLASHBACK OFF;
SQL> ALTER DATABASE FLASHBACK ON;
16. If required restart managed recovery in the standby:
On the standby database, restart recovery:
SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE DISCONNECT;Regards

Error when trying to recover datafile from standby database to primary

hi friends,
getting problem with restoring datafile from backupset taken on standby database to primary database.
os: windows server 2003
db: oracle 11gR1(11.1.0.6)
i've configured standby database on two different hosts.
host1 - primary (db_uinque_name= prod)
host2 - standby (db_uniue_name= prodsby)
I've configure both database with recovery catalog. I take backup on standby database. users' datafile of primary database has been lost.i'm trying to restore from the backupsets taken on standby database.
with the help of - http://download.oracle.com/docs/cd/B28359_01/server.111/b28294/rman.htm#BAJCEFEG
on primary
c:\>rman target sys/password catalog rcat/password
rman>list backup for db_unique_name prodsby;
display the backupsets
rman>restore datafile 4;

please friends, try to help me to solve the problem.
Thanks,

hi.
Its not necessary its a otherway around to recover datafile from this backupset and apply archivelogs to make datafile consistent.
yes, it ain't the right way to restore backup to primary location.
so how would i connect to standby database with primary and recovery catalog.
i need to connect to recovery catalog and primary site because i need to restore to primary location and recovery catalog contain all metadata and backupsets related information.
i also tried the following steps from oracle documentation.
Connect to the standby database as the target database:
CONNECT TARGET sys@standby
You are prompted for a password:
target database Password: password
Connect to the primary database as the auxiliary database:
CONNECT AUXILIARY sys@primary
You are prompted for a password:
target database Password: password
Back up the datafile on the standby host across the network to a location on the primary host. For example, suppose that /disk1/df2.dbf is the name of datafile 2 on the standby host. Suppose that /disk8/datafile2.dbf is the name of datafile 2 on the primary host. The following command would copy datafile 2 over the network to /disk9/df2copy.dbf:
BACKUP AS COPY DATAFILE 2 AUXILIARY FORMAT '/disk9/df2copy.dbf';
Starting backup at 06-NOV-08
using target database control file instead of recovery catalog
allocated channel: ORA_DISK_1
channel ORA_DISK_1: SID=1068 device type=DISK
channel ORA_DISK_1: starting datafile copy
input datafile file number=00004 name=C:\APP\ADMINISTRATOR\ORADATA\prod\USERS01.
