Oracle Datagurad issue

I am implementing a Standby using Oracle datagurad .Today is the deadline :(
Mys stem is Windows 2000 and XP based with ORacle 9i Enterprise edition installed on both.
Following the doc at> http://download.oracle.com/docs/cd/B10501_01/server.920/a96653/create_ps.htm#SBYDB00200 , in step no.3.2.10 Create Oracle Net Service Names I could creat and also TEST the net service name on the PRIMARY database successfully, but when I create and then TEST the the new service on the STANDBY database it gives me TNS No listener error(Standby is in mount state,is it because of this??)
Because of this the archives arent getting transferred to the second location..
Anyone, please advise.
Thanks,
Sandeep
Thanks,
Sandeep

Hi citrus,
Yes the listeneres were started..This is resolved now after explicitly specifying parameter SERVICE_NAMES in the STANDBY parameter file. :)
Everything seems to be working fine now, archives are getting copied and also getting applied.
I now want to know HOW to do the testing to ENSURE that when the primary crashes the control is passed to the STANDBY.Does this happen automatically??or do I need to do any manual configurations??
Any doc that explains this in details?
Thanks,
Sandeep

DataGuard with Oracle 11gR2

Hello All,
I need to know the configuration steps that need to be applied on the primary database and the standby database in a datagurad environment.
Is there any quick links instead of reading the whole Dataguard administration guide?

Error while invoking a WS-Security secured web service from Oracle BPEL..

Hi ,
We are facing some error while invoking a WS-Security secured web service from our BPEL Process on the windows platform(SOA 10.1.3.3.0).
For the BPEL process we are following the same steps as given in an AMIS blog : - [http://technology.amis.nl/blog/1607/how-to-call-a-ws-security-secured-web-service-from-oracle-bpel]
but sttill,after deploying it and passing values in it,we are getting the following error on the console :-
“Header [http://schemas.xmlsoap.org/ws/2004/08/addressing:Action] for ultimate recipient is required but not present in the message”
Any pointers in this regard will be highly appreciated.
Thanks,
Saurabh

Hi James,
Thanks for the quick reply.
We've tried to call that web service from an HTML designed in Visual Studios with the same username and password and its working fine.
But on the BPEL console, we are getting the error as mentioned.
Also if you can tell me how to set the user name and password in the header of the parter link.I could not find how to do it.
Thanks,
Saurabh

HELP! Can not install Oracle 8.1.5 w/ RedHat 6.1!

I can not get Oracle 8.1.5 to install onto Linux RedHat 6.1. The
Oracle installation script generates several errors. I have
tried several attempts, using different options, but they all
generate errors.
Please help. The Oracle Installation scripts appear to be very
buggy... or perhaps they are incompatible with the standard
RedHat 6.1 release. Either way, it is very frustrating.
I have documented one of my (failed) installation attempts below.
Does anyone have any words of wisdom?
I am installing Oracle onto a Dell Latitude CPi PC w/ 128MB RAM,
a 366MHz Pentium II, and RedHat 6.1 (using the standard Linux
2.2.12-2 kernel). RedHat was installed using the standard "Gnome
Workstation" configuration.
The Oralce CD is labeled:
"Oralce 8i Enterprise Edition
Release 8.1.5
for Linux
(c) Oracle Corporation 1999"
I got this CD about one week ago at Oracle OpenWorld '99 in Los
Angeles... it should be their "latest & greatest" version so far.
1. Pre-Installation and ./runInstall
I created an "oracle" Unix account w/ groups "oinstall" (the
primary group) and "dba" (a secondary group).
I created directories /u01 through /u04, belonging to oracle.
I setup .cshrc and sourced it, containing:
umask 022
setenv DISPLAY `hostname`:0
xhost +
setenv ORACLE_BASE /u01/app/oracle
setenv ORACLE_HOME ${ORACLE_BASE}/product/8.1.5
setenv ORACLE_SID cprtest
setenv PATH ${ORACLE_HOME}/bin:${PATH}
setenv LD_LIBRARY_PATH ${ORACLE_HOME}/lib
setenv NLS_LANG US7ASCII
I downloaded jre116_v5 and installed to /usr/local/jre.
Finally, I executed (from the "oracle" Unix account):
cd /mnt/cdrom
./runInstall
Problem: I got the error (from ./runInstall):
Initializing Java Virtual Machine from /usr/local/jre/bin/jre.
Please wait...
Error in CreateOUIProcess(): -1
: Bad address
Workaround: Executed the following commands instead:
cd /mnt/cdrom/install/linux
./runIns.sh
3. runIns.sh and root.sh
I selected the following options (from ./runIns.sh):
Source: /mnt/cdrom/stage/products.jar
Destination: /u01/app/oracle/product/8.1.5
Oracle 8i Enterprise Edition 8.1.5.0.0
Typical (585MB)
Installable Components: Oralce Intelligent Agent 8.1.5.0.0
Global Database Name: cprtest.parkrussell.com
SID: cprtest
Directory for Database Files: /u02
Then (when instructed by ./runIns.sh), I attempted to execute
(from the
"root" Unix account):
cd /u01/app/oracle/product/8.1.5
./root.sh
Problem: I got the error:
"bash: ./root.sh: Permission denied"
The execute bit was not set.
Workaround: I executed:
chmod a+x root.sh
./root.sh
5. Configuration Tools
The Oracle Installer (./runIns.sh) attempted to execute:
A. Net8 Configuration Agent
B. Oracle Database Configuration Agent
Problem: The "Oracle Database Configuration Agent" failed with
the following error message:
"One or more tools have failed. It is recommended but not
required that these tools succeed for this installation.
You can now select these tools, read its details to examine
why they have failed, fix those problems, and retry them.
Or, you can click "Next" to continue."
When I selected the "Oracle Database Configuration Agent" for
more info, I got the following additional details (as the cause
of the error):
"A required command line argument is missing."
The log file
"/u01/app/oracle/oraInventory/logs/installActions.log" recorded:
"Command which is being spawned is /usr/local/jre/bin/jre

failed"
Workaround: There is obviously nothing I can do to fix this
problem. It appears to be an internal bug in ./runIns.sh.
Therefore, I selected "Next" and executed "dbassist" directly.
6. dbassist
I executed:
dbassist
Problem: I got the following error:
"JNLS Execution:oracle.ntpg.jnls.JNLSException
Unable to find any National Character Sets. Please
check your Oracle installation."
Workaround: Press "OK" and ignore the error.
7. dbassist (cont.)
I selected the following options:
Create database
Typical
Copy existing database files from the CD
Global Database Name: cprtest.parkrussell.com
SID: cprtest
Problem: I got the following error:
"CD-ROM drive not detected on this system.
Database not created."
(Note: I've been running the installation scripts from the
CDROM drive this entire time. "df" shows the CDROM drive
mounted on /mnt/cdrom. "ls /mnt/cdrom" works too.)
Workaround: Abort (which generated the additional error: "Unable
to create database. DBCA-00003: No CD-ROM drive detected.") and
run dbassist again, this time using different parameters.
8. dbassist, again
I executed "dbassist" again and selected the following options:
Create database
Typical
Create new database files
Hybrid
Concurrently connected users: 5
Options: Oralce interMedia, Oralce JServer, and iM demos
Global Database Name: cprtest2.parkrussell.com
SID: cprtest2
Create database now
Problem: I got the following error:
"ORA-01012: not logged on"
Workaround: Try, try again.
9. dbassist, one last time
Executed "dbassist" once more and selected the following options:
Create database
Typical
Create new database files
Hybrid
Concurrently connected users: 5
Options: Oralce interMedia, Oralce JServer, and interMedia
demos
Global Database Name: cprtest3.parkrussell.com
SID: cprtest3
Output creation script
Then, I executed (from the "oracle" Unix account):
cd /u01/app/oracle/product/8.1.5/install
setenv ORACLE_SID cprtest3
./sqlcprtest3.sh
Problem: I got the following output:
"Oracle Server Manager Release 3.1.5.0.0 - Production

Workaround: Beats me.
10. sqlplus
I attempted to execute sqlplus, but got the following error
message:
"/u01/app/oracle/product/8.1.5/bin/sqlplus: Permission denied."
The execute bit was not set.
Workaround: I executed:
chmod a+x /u01/app/oracle/product/8.1.5/bin/sqlplus
sqlplus
I gave up for now... there were just too many things wrong with
this installation, starting with the very first command I was
supposed to execute (./runInstaller).
I can't fathom why Oracle's installation script has so many bugs.
Am I just doing something terribly wrong?
Please help.

I'm using enlightenment version 0.15.5-41, which is more recent
than the 0.15.5-37 version (containing the Oracle installer
patch) that you recommended. Unfortunately, it fails when using
this version.
I also tried installing Oracle using twm, with enlightenment
disabled. This didn't help either.
Furthermore, the errors that I'm encountering in the OUI are
not just toward the end of the installation. They happen from
the very beginning, right after I enter "./runInstall", and
continue every step of the way.

Logical operators in Oracle select query

Hello all,
Can i use logical operators in oracle select queries?
for 1 and 0 =0 ; 1 or 0 =0
if i have two fileds in a table COL1 have a value of 1010 and COL2 have a value of 0001.
Is there any way to use select col1 or col2 from table? where or is a logical operator?
Regards,

All the comparison operators, including >, >=, = !=, EXISTS, IN, IS NULL, LIKE and REGEXP_LIKE are really logical operators, since they return logical values. You can use them in SELECT statements, and other places, too.
for 1 and 0 =0 ; 1 or 0 =0

http://download.oracle.com/docs/cd/B28359_01/server.111/b28286/functions014.htm#sthref1080
BITAND is the only logical function that I know of. Many other functions, especially numberical fucntions such as MOD, have applications in logic.
Is there any way to use select col1 or col2 from table? where or is a logical operator?Whenever you have a question, please post a little sample data (CREATE TABLE and INSERT statements), and also post the results you want from that data.
Explain how you get those results from that data.
Always say which version of Oracle you're using.

Strange scenario,Oracle can not display the data in mysql correctly

I use Heterogeneous Service+ODBC to achieve "oracle access mysql"(any other method?),and now i find Oracle can not display the data in mysql correctly:
-------mysql------------
mysql> create table tst(id int,name varchar(10));
Query OK, 0 rows affected (0.00 sec)
mysql> insert into tst values(1,'a');
Query OK, 1 row affected (0.00 sec)
mysql> select * from tst;
------------+
| id | name |
------------+
| 1 | a |
------------+
1 row in set (0.00 sec)
mysql> show create table tst\G
*************************** 1. row ***************************
Table: tst
Create Table: CREATE TABLE `tst` (
`id` int(11) DEFAULT NULL,
`name` varchar(10) DEFAULT NULL
) ENGINE=MyISAM DEFAULT CHARSET=utf8
1 row in set (0.00 sec)
-------------oracle ------------------
SQL> select count(*) from "tst"@mysql;
COUNT(*)
49
SQL> select * from "tst"@mysql;
id
1
SQL> desc "tst"@mysql;
Name Null? Type
id NUMBER(10)

You can make the following query on the result page:
"select * from the_table where movietitle = ? and cinema = ?"
then you set movietitle and cinema to those which the user selected. If the resultset contains more than 0 rows, that means the movie is available.
Below is the sample code, it assumes you have a connection to the database:
PreparedStatement stat = myConnection.prepareStatement("select * from the_table where movietitle = ? and cinema = ?");
stat.setString(1, usersMovieTitleSelection);
stat.setString(2, usersCinemaSelection);
ResultSet res = stat.executeQuery();
if (res.next()) {
out.print("The movie is available");
} else {
out.print("The movie is not available");
}Now just add that to your JSP page. Enjoy ! =)

SSO to Oracle Forms 6.0 and Oracle Reports 6.0

Hi,
Could somebody please explain how I should implement the SSO so that I can log on a forms application?
Should I use external partner app. ??
How can I parse the right parameters to the forms server ??
thanks,
Jerome

Hi,
Oracle Forms 6i does not support Advances Security for SQL*Net if this is what your question is. ASO is supported with Forms 9i and above

Oracle, Null and empty Strings

Currently I'm facing problems with a class, which contains a String, which
is set to "" (empty String).
When the class is persistent, oracle writes null to the table column
(which seems to be common oracle behaviour) and when retrieving the class,
the field is set to null as well, giving me a lot of null-pointer
exceptions.
Anyway ... I can cope with that (just a lot of extra work)
far worse is the problem, wenn searching objects, that have this field set
to "" oder null.
Oracle can't find the records because JDO creates Querys "where
string=null" or "where string=''" , where oracle expects "where string is
null" to find the records.
Is there a workaround or solution ?

Yeah, that would work as well, thx, but since I have to cope with
null-Strings now everywhere in my program, it doesn't hurt just to forbid
empty strings on the program side.
In future times I'll test on Oracle first, then porting to DB/2 - this way
I suppose work is far less to garant compability.
Nevertheless ... having to set the bankcode into quotes is a kodo bug in
my opinion.
Kodo knows the type of classfields (in this case string) and shouldn't
send the parameter as a BigDecimal to the database.
Given that, and having only bankcodes of null (only neccesary when using
Oracle), the method would look like:
public Collection getAccounts (String bankCode)
throws Exception
return getAccounts (Account.class, "bankcode=="+bankcode);
which is how a transparent persistent layer, um, should be , um , I mean
... just transparent ;-D

Couldn't you just do something like:
public Collection getAccounts (String bankCode)
throws Exception
String filter;
if (bankCode == null || bankCode.length () == 0)
filter = "(bankCode == null || bankCode == "")";
else
filter = "bankCode == "" + bankCode + """;
return getAccounts (Account.class, filter);
If I understand the problem correctly, this should work for all the
databases.

What operations are you performing to cause this SQL to be issued? You
say you are having trouble removing objects, but this is clearly not a
DELETE statement. Is this the SQL that is issued when looking up
objects by identity?I'm not removing objects, I was removing just quotes from parameters ;-)
A string column... is it also represented as a string field in your class?Yeah ... just to give you an impression of the code:
First we have a class, representing a bank account:
public class Account {
private AccountMgr myAccountMgr;
private String bankCode;
private String id;
Note, that in nearly all cases bankCode will be a number or null.
I have a second class "AccountMgr", which does all of the persistant stuff
(seaching, making persistent etc.)
This class has two methods, one versatile (protected) to retrieve accounts
by a given filterString and one who just returns accounts by bankCode,
building the expected filterstring. Here is my current working version:
public class AccountMgr {
public Collection getAccounts(String bankCode) throws Exception {
if (bankCode!=null) {
if (bankCode.equals("")) {
throw new Exception("check code, bankCode='' not allowed to get
same behavior from DB2 and Oracle");
// if set, quote the bankCode
bankCode="""+bankCode+""";
return getAccounts(Account.class,"bankCode=="+bankCode);
protected Collection getAccounts(Class accountClass, String filterAdd)
throws Exception {
PersistenceManager pm = MyHelper.getPersistenceManager();
String filter="";
if (filterAdd!=null && !filterAdd.trim().equals("")) {
filter+=filterAdd + " && ";
filter += "myAccountMgr==_accMgr";
Query query = pm.newQuery(accountClass, filter);
query.declareParameters("AccountMgr _accMgr");
return (Collection) query.execute(this);
As you can see, in the first method I have to set the bankCode into
quotes, when it's not null.
This is because otherwise a filter like "bankCode=1234" will be translated
in a way, where 1234 is send as a BigDecimal to the database:
[...] executing statement <4239745>: (SELECT [...] FROM JDO_ACCOUNT t0
WHERE t0.BANKCODE = ? : [reused=1;params={(BigDecimal) 1234}]

Installation Problem on Pentium4 with ORACLE 8.1.7 Client

I tried to Install the ORACLE Client 8.1.7/8.1.6 on Pentium4 with NT platform. On inserting the CD it gave the first prompt and after Clicking the "INSTALL/DE-INSTALL PRODUCTS", system stops. Checking in the TaskManager helps us to know that 'setup.exe' and 'java.exe' were started for a fraction of the second and then stopped.
Tried to explore the issue and it seems that the JAVA version which ORACLE is using for the INSTALLATION of 8.1.7 is NonCompatible with the P4[NT Platform].
However, 8.0.5/8.0.6 Client version were successfully Installed on the same configuration.
Can Anyone help me out in Installing 8.1.6 on P4[NT base].
Thanks in advance

Is the machine you're trying to install on the
machine your display is running on?
If not, doing a
'xhost + name_of_machine_you_are_installing_on'
on the machine your display is running on should do the
trick.
Hope that helps.
