SQL*Net 2.3 accessing Oracle9i?
Can SQL*Net 2.3 be used to access Oracle9i database?
If so, will installing SQL*Net 2.3 damage to my current Oracle9i configuration?
Many thanks

An Oracle 8 client can connect to an Oracle 9 (and Oracle 7) database without problems. As Justin indicated you have to try "SID=" instead of "SERVICE_NAME=". Another possibilty is to play around with the domain names. Sometines it works with a domain extension, sometimes without, and sometimes with .WORLD.
I know Oracle has a theory behind all this, but I never seemed to have mastered it. After years of editing my tnsnames.ora file, I still haven't really figured out what the idea behind it is. I see many combinations in my tnsname.ora file which seem to work for different databases.

Are there a patch to sql*net v1 access version 2?
My client is MS-DOS and running sql*net v1
my server is Oracle E7.1.6 under Sco unix OpenServer 5.0.2 and running sql*net v1 and v2.
How can I upgrade my server to Oracle 7.3.x or 8.x. without upgrade my client version
Are there a patch to sql*net v1?
so I can use version 1 access version 2.
How can I get the patch?
Thanks.
nullYour question is unclear, and does not appear to be related to the Oracle Migration Workbench.

Query started taking longer time with SQL*Net message from dblink
Hi,
Since Yesterday we started see one query which normally used to take 3 min but now it started taking 70 min after a small change do the query instead of accessing view we started accessing directly table.
Both Schema's are on same DB.

SQL Developer fails to access update center via http proxy
Hi,
I've configured HTTP Proxy exactly like MS-IE. Anyway, sql developer fails to access web. This is the error message:
java.io.IOException: Server returned HTTP response code: 407 for URL: http://htmldb.oracle.com/pls/otn/f?p=38606:2
at sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:1149)
at oracle.ideimpl.webupdate.CheckMasterListRunnable.run(CheckMasterListRunnable.java:131)
at java.lang.Thread.run(Thread.java:595)
Using the same URL in IE gives the following result:
<?xml version="1.0" encoding="UTF-8" ?>
- <centers xmlns="http://xmlns.oracle.com/jdeveloper/update/master">
- <center id="oracle.sqldeveloper.webupdate.internal">

<url>http://htmldb.oracle.com/pls/otn/f?p=raptor:center</url>
<name>Official Oracle Extensions</name>
</center>
</centers>
What's wrong?
I'm using sql developer 1.0.0.14.22.
MartinGiven that the update centre worked for me with proxy authentication in v1422 (and Production v1467 - I would recommend that you upgrade to this with a full download if you can't sort out your proxy issues), I would assume that it is not a SQL Developer bug.
Are you still getting HTTP 407 errors when you have entered your username and password?
Unfortunately, I don't know what username/password expectations a RADIUS based proxy authentication would expect. The only thing I can suggest to try is to explicitly put your username/password in your MS-IE proxy setup and see if you can still access the http://htmldb.oracle.com/pls/otn/f?p=38606:2 URL through IE. If this fails through IE, the username/password that you are supplying are not what the proxy is expecting. -
SQL server can't access network share
Hello,
I am facing an issue where the SQL server can't access the network share. The network share is mounted by a domain user who is also configured as Administrator on the server.
Through SQL Server management studio as well as PoweShell script when i try to access the share in order to attach the database contained within the share, i get the error "Unable to find the file specified". I can't mention the network drive to
the SQL management GUI file browser too if i try to attach the database through GUI.
For all SQL services, I changed the service log on account to be the same account which mounts the network share.
As work around -
I launched a command prompt under NT Authority \ SYSTEM (LocalSystem) account and mounted the drive to the same location which lead to adding one more connection but under local system account. With this change, the SQL server was able to access the network
share!
I couldn't understand whey SQL expects the network share to be mounted under local system account even if all the SQL services are running under domain account ? I want SQL to be able to access the network share without opting for above work around.Hello,
I couldn't understand whey SQL expects the network share to be mounted under local system account even if all the SQL services are running under domain account ? I want SQL to be able to access the network share without opting for above work around.
It doesn't have to be. The workaround is only a temporary fix and is certainly not a good idea. I would not use mounted folders with SQL Server, at all, period.
The reason you're having difficulty is that when the folder is mounted, it's mounted for YOUR session not ALL sessions. SQL Server has already started its services and is running under its' own session and is not privy to the things you do to change the
environment. For example, if you changed a system or user variable (for example, a SET variable) SQL Server would have no idea about this because when it started, that variable either didn't exist or was something else. This is not SQL Server's fault but how
Windows works (this information is stored in the Process Environment Block [PEB]) for any windows process.
As other's have said, don't use mounted drives - use a UNC path. UNC paths are 100% supported on 2012+ as well as running databases on a SMB 3.x share (UNC pathed of course).
If you absolutely must use a mounted drive, enabled xp_cmdshell access (through sp_configure) and run the net use command through xp_cmdshell. I, once again, would highly advise not doing this and using an UNC path.

JDBC, SQL*Net wait interface, performance degradation on 10g vs. 9i
Hi All,
I came across performance issue that I think results from mis-configuration of something between Oracle and JDBC. The logic of my system executes 12 threads in java. Each thread performs simple 'select a,b,c...f from table_xyz' on different tables. (so I have 12 different tables with cardinality from 3 to 48 millions and one working thread per table).
In each thread I'm creating result set that is explicitly marked as forward_only, transaction is set read only, fetch size is set to 100000 records. Java logic processes records in standard while(rs.next()) {...} loop.
I'm experiencing performance degradation between execution on Oracle 9i and Oracle 10g of the same java code, on the same machine, on the same data. The difference is enormous, 9i execution takes 26 hours while 10g execution takes 39 hours.
I have collected statspack for 9i and awr report for 10g. Below I've enclosed top wait events for 9i and 10g

I put full blame for the slowdown on SQL*Net message to client wait event. All I could find about this event is that it is a network related problem. I assume it would be true if database and client were on different machines.. However in my case they are on them very same machine.
I'd be very very grateful if someone could point me in the right direction, i.e. give a hint what statistics should I analyze further? what might cause this event to appear? why probable cause (that is said be outside db) affects only 10g instance?
Thanks in advance,
Rafi.Hi Steven,
Thanks for the input. It's a fact that I did not gather statistics on my tables. My understanding is that statistics are useful for queries more complex than simple select * from table_xxx. In my case tables don't have indexes. There's no filtering condition as well. Full table scan is what I actually want as all software logic is inside the java code.
Explain plans are as follows:
======= 10g ================================

Thanks for pointing me difference in table scans. I infer that 9i is doing single-block full table scan (db file sequential read) while 10g is using multi-block full table scan (db file scattered read).
I now have theory that 9i is faster because sequential reads use continuous buffer space while scattered reads use discontinuous buffer space. Since I'm accessing data 'row by row' in jdbc 10g might have an overhead in providing data from discontinuous buffer space. This overhead shows itself as SQL*Net message to client wait. Is that making any sense?
Is there any way I could force 10g (i.e. with hint) to use sequential reads instead of scattered reads for full table scan?
I'll experiment with FTS tuning in 10g by enabling automatic multi-block reads tuning (i.e. db_file_multiblock_read_count=0 instead of 32 as it is now). I'll also check if response time improves after statistics are gathered.
Please advice if you have any other ideas.
Thanks & regards,
Rafi. -
Can u access Oracle9i Reports objects from Java Code?
Hi,
How can you access Oracle9i Reports (Rel 2) objects like Body, DataSource, Groups etc from Java Code?
What are the available APIs?
I went thru the APIs at http://otn.oracle.com/products/reports/htdocs/getstart/docs/Javadocs/oracle/reports/plugin/definition/package-summary.html
However various constructors stated in these APIs are using classes from "oracle.reports.definition" package which are difficult for me to locate.
For eg. Report constructor is using oracle.reports.definition.RWReport and there is no API documentation available for RWReport class.
Please suggest me the site for the above APIs or the method to get a reference to "Report" instance.
Thanks
Rakesh.Thanks Tugdual for your quick reply.
Thats exactly what I am trying to do. I want to develop a utility which can have a subset of Report Developer's functionality.
Currently using Reports Developer & Report Wizard, I can create a report by providing SQL statement and few parameters (like Report Style, Calculated Fields, Template file etc). I want to put all these parameters in a XML file and run my java utility (based on the APIs which I am looking for) which will use these XML parameter file and generate a '.rdf' file.
Also, could you please suggest me the site for oracle.reports.definition package API or the way to get a reference to oracle.reports.plugin.definition.Report instance.
Thanks,

SQL*NET V1,V2 사용 시 ORA-9241, ORA-9301 조치방법
제품 : SQL*NET
작성날짜 : 1995-11-07
SQL*Net V1, V2 사용 시 ORA-9241, ORA-9301 조치 방법
==================================================
ORA-9241, ORA-9301 에러는 개발 툴이 해당 툴 또는 SQL*Net에 필요한 메세지
화일을 찾을 수 없을 때 발생한다.
* SQL*NET V 1
1. DOS 환경에서 SET을 수행하여 CLIENT상에 CONFIG라는 환경변수가 설정되어
있는지 확인한다.
2. 설정되어 있지 않으면 ROOT directory에서 CONFIG.ORA 또는 ORACLE.INI라는
화일을 찾는다. (Directory Search)
(상기의 화일은 보통 \ ORACLE_HOME 또는 \ WINDOWS Directory 내에 있다.)
상기의 화일이 존재하면 DOS환경에서 다음의 CONFIG 환경변수를 추가한다.
C:\> SET CONFIG = <PATH> \ORACLE.INI
이로써 문제가 해결될 수 있으며, DOS 환경에서 SET과 PATH 명령을 수행하여
ORACLE_HOME 디렉토리가 PATH에 설정되어 있는지, 그리고 CONFIG가 DOS환경에
설정되어 있는지 확인하고 WINDOWS를 실행해야 한다.
3. 환경변수 CONFIG가 이미 설정되어 있고 ORACLE.INI 또는 CONFIG.ORA를
지시하고 있는데도 ORA-9241 또는 ORA-9301 에러가 계속 발생한다면
WINDOWS를 완전히 빠져나와서 ORACLE.INI를 CONFIG.ORA 라는 또 다른 화일로
복사를 하고 DOS 환경에서 환경변수 CONFIG를 추가한다.
C:\> SET CONFIG = <path> \CONFIG.INI
4. 만일 ORACLE.INI 를 autoexec.bat 파일에 SET CONFIG = <PATH> \ORACLE.INI
와 같이 추가하여도 계속 에러가 발생한다면 ORACLE.INI 파일에
LOCAL = t:hostname:sid 을 추가한다.
5. 단계2 또는 단계3 에서 문제가 해결된다면 이를 AUTOEXEC.BAT 화일에 SET
CONFIG문을 추가한다.
* SQL*NET V 2
1. ORACLE.INI 파일에 LOCAL = <V2 service name>을 추가한다. 만일 ORACLE.INI
파일에 LOCAL 파라미터를 추가한 후에도 계속 ora-9301 에러가 계속 발생한다면
autoexec.bat 파일에 SET CONFIG = <PATH> \ORACLE.INI를 추가한다.
[주의 1] CONFIG가 ORACLE.INI를 지시하도록 설정하면 나중에 다시 설치할
문제가 발생할 수 있다. 그럴 때는 AUTOEXEC.BAT 에서 SET CONFIG 행을
삭제하고 다시 Booting 한후 설치를 시작한다.
[주의 2] MS ACCESS를 이용하여 ORACLE의 데이타를 질의할 경우는 환경변수를
다음과 같이 설정한다.
SET CONFIG_FILES = <path> \ORACLE.INI
[주의 3] SET 다음의 CONFIG 나 CONFIG_FILES 은 반드시 대문자 이어야 한다. -

6. Tips
* 실제로 동작하기 위해서 server process를 기동시켜주는 command
procedure인 ORASRV_NETV2.COM 이 있어야 하는데 TNS_ADMIN 에
sample이 있으므로 수정해서 사용하도록 한다.
이때 반드시 ORA_DB directory가 정의되어 있어야 한다.
* SYLOGIN.COM이나 LOGIN.COM에 다음의 조건문을 넣어서 Network
Access를 처리할 수 있다.
$ IF F$MODE() .EQS. "NETWORK" .OR. F$MODE() .EQS. "OTHER" -
THEN EXIT
* 만약 listener나 server process가 아무런 tracing information을
남기지 않고 계속 죽는다면 VMS Accounting Utility를 이용하여
process termination status를 점검해본다.
$ ACCOUNTING/FULL/IDENT=<pid>Depending on how large is your database you can use either exp/imp utility to migrate the data after installing the Oracle8i on your O/S or Inplace db upgrade. Otherwise backup your current Oracle7.x release and install the Oracle8i Software only without the database. Open old database using the Oracle8i svrlmgrl utility. Upgrade using the upgrade scripts available in $ORACLE_HOME/rdbms directory. Also read the documentation for any additional information on issues on the upgrades.
I am not sure about the SQL Net versions, but SQL Net Version 2 should work against net8 listener. You could try v1 too.

This link Troubleshooting Oracle Net Services says to check SQLNET.LOG on the server, however, I do not have access to the server. Is there another way to tell which version?
Network connections have two sides .. the client and the server. The two sides do not have to be the same version. If you don't have access to the server, then you are only concerned with the client.
SQLNET.LOG only gets written/created in response to a problem. And it gets written in the "current" directory of the process that had the problem. So you could have several of them .. or none.

I am being told that I need something called SQL*Net to get a front end working to access a remote (like 1/2 way around the world) database. I do have the most recent Oracle client tools installed and it seems like it has the necessary networking configuration tools. However, my contact in Denmark is saying to get SQL*Net, the client tools won't cut it and I need to download a full 9i database. Is there any reference out there stating what I'll need and how I configure it?
Generally Oracle client software is installed on Windows, if it is your case these books can be very useful.

How to decipher SQL*Net protocols/packets?
hi,
we have a customer that sells compliance solutions that basically track and audit information at the packet level. in order to expand their customer base they would like to offer their solutions to customer that have business systems built on Oracle Forms 6.x and Pro*C. to do this they need to understand how our network communication works. is this something that is generally available? here are some details for what the partner wants from us ...
Their product intercepts the communication between a typical Db client and Db server at packet level, performs analysis on the packets and extracts the information required for SOX compliance. It's been successfully installed and working for various versions of Oracle servers and Clients, however it does not handle Oracle Forms and pro*C clients.
It also wrks for pro*c client except for bind variables and arrays.
We need information on packet formats during communication between Oracle database and Forms and pro*c clients. This will help our product to work for SOX compliance for the customers who have FORMS and pro*c clients without replacing them
I know that form Forms to DB its SQL*Net, not sure what the protocol is for PRO*C to DB communication but do we have documentation on both?Assuming you are on Windows, you can download the client installable from
http://download.oracle.com/otn/nt/oracle10g/10201/10201_client_win32.zip -- for Oracle 10g client
http://download.oracle.com/otn/nt/oracle11g/win32_11gR1_client.zip -- for Oracle 11g client
