Oracle 10g inside IPX/SPX network

Hi All,
I am a newbie in Oracle. May I know if it is possible to setup an Oracle database inside an IPX/SPX network? I have tried setting up the TNS and listeners according to some "HOW-TO" docos for 8i but it didn't work......
ps. That network must not use TCP/IP hence comes the problem...
Thank you very much!

There are (or were) NetBIOS drivers for the NT kernel that allowed you to run named pipes over IPX/SPX. This enabled Microsoft services (like file and print sharing) to work across a Novel network (especially since the default NetBEUI was not routable).
Oracle at one time even shipped the Oracle RDBMS server as a NLM. :-)
But I find it very strange that you are still using an IPX/SPX network. This pretty much died out at the end of last century. IP networks provide significantly more flexibility. increase robustness, better security and so on.

Oracle 10g CRS autorecovery from network failures - Solaris with IPMP

Hi all,
Just wondering if anyone has experience with a setup similar to mine. Let me first apologise for the lengthy introduction that follows >.<
A quick run-down of my implementation: Sun SPARC Solaris 10, Oracle CRS, ASM and RAC database patched to version 10.2.0.4 respectively, no third-party cluster software used for a 2-node cluster. Additionally, the SAN storage is attached directly with fiber cable to both servers, and the CRS files (OCR, voting disks) are always visible to the servers, there is no switch/hub between the server and the storage. There is IPMP configured for both the public and interconnect network devices. When performing the usual failover tests for IPMP, both the OS logs and the CRS logs show a failure detected, and a failover to the surviving network interface (on both the public and the private network devices).
For the private interconnect, when both of the network devices are disabled (by manually disconnecting the network cables), this results in the 2nd node rebooting, and the CRS process starting, but unable to synchronize with the 1st node (which is running fine the whole time). Further, when I look at the CRS logs, it is able to correctly identify all the OCR files and voting disks. When the network connectivity is restored, both the OS and CRS logs reflect this connection has been repaired. However, the CRS logs at this point still state that node 1 (which is running fine) is down, and the 2nd node attempts to join the cluster as the master node. When I manually run the 'crsctl stop crs' and 'crsctl start crs' commands, this results in a message stating that the node is going to be rebooted to ensure cluster integrity, and the 2nd node reboots, starts the CRS daemons again at startup, and joins the cluster normally.
For the public network, when the 2nd node is manually disconnected, the VIP is seen to not failover, and any attempts to connect to this node via the VIP result in a timeout. When connectivity is restored, as expected the OS and CRS logs acknowledge the recovery, and the VIP for node 2 automatically fails over, but the listener goes down as well. Using the 'srvctl start listener' command brings it up again, and everything is fine. During this whole process, the database instance runs fine on both nodes.
From the case studies above, I can see that the network failures are detected by the Oracle Clusterware, and a simple command run once this failure is repaired restores full functionality to the RAC database. However, is there anyway to automate this recovery, for the 2 cases stated above, so that there is no need for manual intervention by the DBAs? I was able to test case 2 (public network) with the Oracle document 805969.1 (VIP does not relocate back to the original node after public network problem is resolved), is there a similar workaround for the interconnect?
Any and all pointers would be appreciated, and again, sorry for the lengthy post.

Oracle 10G support with ASM in Windows VM

Hi,
Planning to use Oracle 10G inside a Windows VM with paravirtualized drivers. We will be using iSCSI software initiator from within the windows VM directly to provision LUNs and use ASM as well.
Will this combination fall under the supported category?
thanks!

There are many different organizations involved with your question about being supported, so your best answer would be an official one directly from your Sales contact. There are mostly technical folk in these forums who can tell you if it will work, but that is not stating a support policy.

Oracle 10G Non-Network install - OEM will not start when on the LAN.

Greetings,
Got through a non-networked 10G Enterprise installation OK; I chose to create the orcl schema, connected to it through various utilities, added new tablespace, and all was well. I also checked my Host Name by pinging it in DOS, it showed me the IP address of the MS loopback adapter which is what I was expecting.
Once I connected the same machine to the LAN (and internet) and re-booted, for some reason the Host Name was now assigned the dynamic IP address of the LAN and not LAN2 (which is the loopback adapter that is assigned a static local IP address). It did this even though I had already added an entry in the /etc/hosts file that explicitly assigns a static IP address to the Host Name (as recommended in the Oracle 10G pre-installation instructions). I also could not get the OEM to launch a webpage, run and connect to the orcl database after the re-boot; I am wondering if this is related to the IP address assigned to Host Name changing; maybe the Oracle agent can no longer resolve the URL for some reason?
In the end I find that the only way to insure I can have a working Oracle environment and be on an active network at the same time, is to bring up the Oracle environment on a standalone system first, and once Oracle is running connect the system to the network. Is there no way to automate this process?
The format of the hosts file entry recommended by the Oracle 10G pre-installation instructions is as follows:
===========================================================
IP_address hostname.domainname hostname
where:
IP_address is the non-routable IP address you entered for the loopback adapter.
hostname is the name of the computer.
domainname is the name of the domain.
For example:
10.10.10.10 mycomputer.mydomain.com mycomputer
==========================================================
In my case since I am not part of a Windows domain (but am part of a Windows Workgroup), I added an entry in the /etc/host file that looks like the following:
# Copyright (c) 1993-1999 Microsoft Corp.
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
# For example:
# 102.54.94.97 rhino.acme.com # source server
# 38.25.63.10 x.acme.com # x client host
127.0.0.1 localhost
192.168.110.250 IBM-6AB1330E158
==> Note that I did not add the domain name to the entry I created since I am not part of a domain, I also used the format I found in the etc/hosts file which is:
IP_address hostname.domainname
- not -
IP_address hostname.domainname hostname
Which is the format recommended in the Oracle 10G pre-installation instructions; this does leave me wondering which format is correct...
Thanks in Advance for any help,
ADG13

I have not. I am hoping someone (maybe even from Oracle support) will step up and officially tell us we are either right or wrong in the way we are approaching this. From the research I have done on the internet it sounds like this should work, you should be able to have Oracle starting and running fine whether you boot connected to the LAN or not, assuming you have created the MS loopback adapter, assigned it a static IP, and changed the hostname entry in etc/hosts file as part of the 10G WinXP recommended pre-installation instructions.
And yet I find I have to start Oracle when I am not connected to the LAN or the services will not start correctly. If this is a "feature" then hopefully someone will tell us and maybe give us a workaround or give us an idea if this will be addressed in a future release. Having said that and in fairness to the Oracle product; being a developer I have other products installed on my machine that have special networking setup needs also, and in my case this could be exasperating or even possibly causing this Oracle problem I am having. To be specific I have software for 2 different VPNs installed so I can tunnel into 2 private networks. One of these VPNs require me to make use of a DNS Suffix (as shown below) which might be contributing to my problems, not sure. I also have VMWare installed which uses it own network adapters when it is running, so you can see how things could get a little hairy... at any rate, there is my 2 cents worth (or is that 5 cents? : )

Oracle 10g Installtion error Network Configuration requirements ... failed

Checking Network Configuration requirements ...
Check complete. The overall result of this check is: Failed <<<<
Problem: The install has detected that the primary IP address of the system is DHCP-assigned.
Recommendation: Oracle supports installations on systems with DHCP-assigned IP addresses; However, before you can do this, you must configure the Microsoft LoopBack Adapter to be the primary network adapter on the system. See the Installation Guide for more details on installing the software on systems configured with DHCP.

Are you installing Oracle 10G R2? If this is the case then for DHCP network environments, you need to create a Microsoft loop back adapter.
Microsoft Loopback Adapter creation:
===========================
Step 1: Programs -> control panel -> Add Hardware.
Step 2: In the Add Hardware wizard. Click 'Next' and select 'Yes, I have already connected the hardware'. option and click on 'Next'.
Step 3: Select the last option 'Add a new hardware device' from the 'Installed hardware' window and click on 'Next'.
Step 4: Select the last option 'Install hardware that I manually select from the list (Advanced) and click on 'Next'.
Step 5: Select 'Network adapters' in 'Common hardware types' list and click on 'Next'.
Step 6: Where you can see 'Microsoft loopback adapter' on the right hand side of the frame.
Step 7: proceed with all default installation and then try installing Oracle.
I hope this will suffice.
Thanks

Are you talking about the Enterprise Manager Console provided by the oracle or some other enterprise software? If it is enterprise software then you need to the do the proper setting for network connection to database. Probably you will have to configure tnsname.ora and sqlnet.ora. Can you connect through SQL*Plus utility? Go to Run-->SQLPLUSW type in the username password and tnsnames entry for the database. See if you can connect. If not post us the error message.

Problem with Oracle 10g RAC VIP network setting at Solaris 9

Dear All,
I have tried to set up a Oracle 10g RAC Release 2.
With OS solaris 9, and 2 nodes.
The nodes setting as the following:
nodes 1:
Public address: 172.16.0.121
Private address: 192.168.0.121, 192.168.1.121 (dual path for heart beat)
nodes 2:
Public address: 172.16.0.122
Private address: 192.168.0.122, 192.168.1.122
And i have assigned two IP adress 172.16.0.131, 172.16.0.132 as the VIP address for the
RAC.
And the following is the /etc/hosts file:
root@shk01 # cat /etc/hosts
# Internet host table
127.0.0.1 localhost
# public address
172.16.0.121 shk01 loghost
172.16.0.122 shk02
# heart beat
192.168.0.121 shk01-priv1
192.168.1.121 shk01-priv2
192.168.0.122 shk02-priv1
192.168.1.122 shk02-priv2
# VIP address
172.16.1.131 vip-shk01
172.16.1.132 vip-shk02
But when i run the command "$ ./runcluvfy.sh comp nodecon -n shk01,shk02 -verbose"
it shows the error:
ERROR:
Could not find a suitable set of interfaces for VIPs.
Result: Node connectivity check failed.
I did try to add the VIP address on bge0:1, as i using bge0 for the public address.
Both nodes i did using the same interface name for it.
Anyone have idea for me to check out the error?
Also, I have other question about the raw device.
As there is option for setting for ASM or raw device. If choosing raw device, does it mean that it just need to
format the storage disk but without newfs it? And then the Oracle program will able to handle it?
Thanks,
Xentar

You don't seem to state categorically that you are using Solaris Cluster, so I'll assume it since this is mainly a forum about Solaris Cluster (and IMHO, Solaris Cluster with Clusterware is better than Clusterware on its own).
Clusterware has to see the same device names from all cluster nodes. This is why Solaris Cluster (SC) is a positive benefit over Clusterware because SC provides an automatically managed, consistent name space. Clusterware on its own forces you to manage either the symbolic links (or worse mknods) to create a consistent namespace!
So, given the SC consistent namespace you simple add the raw devices into the ASM configuration, i.e. /dev/did/rdsk/dXsY. If you are using Solaris Volume Manager, you would use /dev/md/<setname>/rdsk/dXXX and if you were using CVM/VxVM you would use /dev/vx/rdsk/<dg_name>/<dev_name>.
Of course, if you genuinely are using Clusterware on its own, then you have somewhat of a management issue! ... time to think about installing SC?

Oracle 10g ODBC driver with Windows 7 32 bit connecting to Excel

Hi Everyone,
I'm having an issue connecting to our oracle 10g database (64 bit system) from a 32 bit windows 7 installation running excel 2010/2007 using odbc drivers. Our excel spreadsheets worked without issue in windows xp.
In windows 7 I have been able to install the odbc driver via the following method:
1. Download the oracle 'basic' client and oracle 'odbc' client from www.oracle.com and extract the contents:
instantclient-basic-win32-10.2.0.3-20061115
instantclient-odbc-win32-10.2.0.3-20061115
2. Create a folder 'oracle' and place the instantclient_10_2 folder inside.
3. Ensure all the basic and odbc files reside in this folder.
4. Create a 'network' folder within instantclient_10_2
5. Create an 'admin' folder within 'network'
6. Create sqlnet.ora and tnsnames.ora files within the 'admin' folder:
7. Run 'obdc_install' within the instantclient_10_2 folder
8. Download and run the oracle odbc driver exe file from www.oracle.com (ORA10203.exe)
9. Go to Control Panel -> Administrative Tools -> Data Sources and create a new System DN
This allows excel spreadsheets connecting ONLY to oracle to function.
Unfortunately some of our spreadsheets connect to both a MySQL database as well as oracle. Spreadsheets connecting only to MySQL also function correctly, however, as soon as the vb associated with a spreadsheet includes a mysql call followed by an oracle call the spreadsheets fail. In Excel 2007 excel crashes completely everytime. In Excel 2010 the mysql data is generated, then when the script hits to oracle odbc connection there is a long pause, the oracle ODBC driver connect pops up requesting a username/password (this didn't happen in xp), then the data source selection pops up, then the username/password connect screen pops up again, and finally it fails with a runtime error '1004' General ODBC error.
If you look at the VB script it's failing at the Refresh BackgroundQuery statement in the ODBC connection block:
With Worksheets("Oracle1").QueryTables.Add(Connection:= _
"ODBC;DSN=Oracle_ODBC;UID=user;PWD=password;SERVER=ORACLE_LINUX;", _
Destination:=Worksheets("Oracle1").Range("A1"))
.CommandText = strSql
.Name = "Oracle1_data"
.FieldNames = True
.RowNumbers = False
.FillAdjacentFormulas = False
.PreserveFormatting = True
.RefreshOnFileOpen = False
.BackgroundQuery = True
.RefreshStyle = xlOverwriteCells
.SavePassword = True
.SaveData = True
.AdjustColumnWidth = True
.RefreshPeriod = 0
.PreserveColumnInfo = True
.Refresh BackgroundQuery:=False
End With
Does anyone know how to get around this? It's very important!!
Also if you try to edit the oracle ODBC connections in Control Panels -> Administrative Tools -> Data Sources, ODBC crashes 95% of the time.
Advice greatly appreciated!!

Well, here's what I'd check anyway..
1) get Process Explorer from http://sysinternals.com
2) make a mysql connection, get a list of dll's loaded (include the location and version columns in the lower pane output)
3) close that, then make an ora odbc connection, get a list of dlls.
4) close that, then make a mysql connection followed by an ora odbc connection, get a list of dlls
5) compare the lists of loaded dlls. In particular, the difference between #3 and #4, is there a dll dependency that gets loaded by oracle's odbc that comes from a different location when you've opened a mysql connection first?
May or may not help, but might turn up a difference to help point you in a direction.

Encryptind and decrypting database column in oracle 10g

hi guys...
i am sai sandeep,i got a doubt how to encrypt a database column in oracle 10g..?
i am using a table " emp_uid " ,and strtucture as follows,
create table emp_uid(user_id varchar2(20),pwd varchar2(20));
i need to encrypt a pwd column in the emp_uid.
how to do it..?
thanking u advance.....

Ok, here's a basic example...
SQL> create table myusers (username varchar2(30), password varchar2(40));
Table created.
SQL> create or replace procedure add_user(username in varchar2
2                                      ,password in varchar2) is
3 begin
4    insert into myusers (username, password)
5      values (add_user.username
6             ,dbms_crypto.hash(utl_raw.cast_to_raw(add_user.username||'!'||add_user.password)
7                              ,dbms_crypto.hash_sh1)
8             );
9    commit;
10 end;
11 /
Procedure created.
SQL> exec add_user('Fred','Fr3ddy')
PL/SQL procedure successfully completed.
SQL> select * from myusers
2 /

Fred                           E5C975DB4C0A1CF65683E36421A6305F09F4EA9A
SQL> set serverout on;
SQL> create or replace procedure loginuser(username in varchar2
2                                       ,password in varchar2) is
3    v_hash     varchar2(40);
4    v_username varchar2(30);
5 begin
6    v_hash := dbms_crypto.hash(utl_raw.cast_to_raw(loginuser.username||'!'||loginuser.password), dbms_crypto.hash_sh1);
7    select username
8    into   v_username
9    from   myusers
10    where username = loginuser.username
11    and    password = v_hash;
12    dbms_output.put_line('User: '||v_username||' logged in.');
13 exception
14    when no_data_found then
15      dbms_output.put_line('Username/Password is not valid!');
16 end;

Procedure created.
SQL> exec loginuser('Fred','Freddy');
Username/Password is not valid!
PL/SQL procedure successfully completed.
SQL> exec loginuser('Fred','Fr3ddy');
User: Fred logged in.
PL/SQL procedure successfully completed.
Ideally you would do the hashing of the password inside the client side application so only the Hashed value goes over the network, but the above demonstrates the principle of using hashes to store passwords. Because it's a one way algorithm, only a brute force method can be used to try and determine the original password. There is no way to directly un-hash the value. To check for a valid login, we don't retrieve the password and try to unhash it to compare against what the user has supplied, we actually take what the user has supplied and hash that in the same way and then compare the hashes.
The point of including the username or some other data in the hashing process means that if two users have the same password, they will still have different hash values, so it won't be apparent they are the same passwords. In my example, the point of putting another character between the concatenation of username and password is in case the username and password together would give the same result e.g.
If we had one user "Fred" with password "Fr3ddy" then just concatenating the strings would give "FredFr3ddy".
If we had another user "FredF" and he happened to choose a password "r3ddy" then just concatenating those would also give "FredFr3ddy"
by introducing a known breaking character they would be different e.g. "Fred!Fr3ddy" and "FredF!r3ddy" and hence give different hash values.
That's the basics of how passwords are stored for security.
It would take a lot of processing power and brute force methods just to determine a single password for a single user when using hashing methods of security.
With encryption, a brute force method could be used to find the decryption key, and once found that could be used to decrypt ALL the encyrpted data, hence it is less secure, especially when some clever person will no doubt have written the key down somewhere so they don't forget it. With hashing there's no key to write down.

SOAP over TCP using Oracle 10g

Hi everyone
I am currently working with a client and they have recently upgraded a legacy DB from Oracle 6i to Oracle 10g and now wish to be able to provide some functionality of this legacy system as a web service to their other J2EE n-tier applications.
The Oracle 10g and J2EE applications sit securely inside a corporate network. As such it would be preferable if service calls to the 10g database could be exposed using SOAP over TCP as opposed to using HTTP to speed up performance a little bit.
This is a baby step, point-to-point, SOA solution that they wish to implement before progressing to a more managed solution (eg ESB) in the future.
As I am not an Oracle expert I would like to know if this can be done and if so is it a trivial or complicated thing to achieve?
Any help would be greatly appreciated!

Hi Hatchman,
As Eric described, Oracle does not support SOAP over TCP yet. If your goal is to improve the performance, I don't think you'll gain substantial performance improvement by bypassing HTTP layer. Although it depends upon the nature of the service implementations, typically the bottleneck lies in xml processing not in the transport layer.

Error while sending a mail using UTP_MAIL package in Oracle 10g

Hi,
We are using UTP_MAIL package to send a mail from Oracle 10g.We have follwed the following steps ...
SQL> connect sys/password as sysdba
Connected.
SQL> @$ORACLE_HOME/rdbms/admin/utlmail.sql
Package created.
Synonym created.
SQL> @$ORACLE_HOME /rdbms/admin/prvtmail.plb
Package body created.
SQL > alter system set smtp_out_server = '<mail_server_ip:25>' scope =spfile;
System altered..
Now we try the code
begin
utl_mail.send(
sender => 'sender's mail',
recipients => 'receiver mail',
CC => 'optional',
subject => 'Testing utl_mail',
message => 'Test Mail'
end;
But we get the following error...
ERROR at line 1:
ORA-29278: SMTP transient error: 421 Service not available
ORA-06512: at "SYS.UTL_SMTP", line 21
ORA-06512: at "SYS.UTL_SMTP", line 97
ORA-06512: at "SYS.UTL_SMTP", line 139
ORA-06512: at "SYS.UTL_MAIL", line 405
ORA-06512: at "SYS.UTL_MAIL", line 594
ORA-06512: at line 2
We also tried connecting to the mail server through telnet .But it is not getting connected..
Please help us to solve the issue.

From your own posting you may have the clue, if you try to access your mail server through telnet and it is not successful, it means the service is down or there are networking issues.
On pre 10gR2 versions there was a bug 4083461.8. It could affect you if you are on 10gR1
"Bug 4083461 - UTL_SMTP.OPEN_CONNECTION in shared server fails with ORA-29278 Doc ID: Note:4083461.8"
This was fixed on 10gR2 base and on 9.2.0.8.0

Enterprise 600 m602n IPX/SPX Configuration

Good Day All
My organization recently purchased a number of hp laserjet enterprise 600 m602n printers to replace an ageing fleet of 4000 series printers attached to external jetdirect cards. The printers being replaced recieve jobs by both TCP/IP IPv4 and IPX/SPX. Page 62 of the m602n user manual says IPX/SPX is a other supported network protocol. Page 147 says "The HP Embedded Web Server does not support IPX-based product connections." My problem is if it is a supported network protocol how do I configure it? I see nothing in the Web Server which is to be expected from the verbage on page 147, but I also see no means to do so going through the front menu controls or via TELNET. Any thoughts would be appreciated.
Thank You
This question was solved.

According to HP Business Support the notation that it is a support network protocol in the user manual is a misprint. It does not support IPX/SPX directly.

How to avoid of application running on Oracle 10g to be copied?

I am a newbie to the security issues, so I need your help, please, where to start / what to read:
I have an application running across many customers on Oracle 10g. I have faced lately that our users
can use their daily backups to establish a totaly new database on a same / different server
and point our application to use it as well.
Is there any way to avoid it? F.e. I thought to use SELECT * FROM v$instance; to get the server instance details, and
in result with some other function to obtain, let say, local server's (WIN2003) details,
such as HD Serial Number, MAC number or so and then to check these values each time user runs the application.
Is it the correct way? What are the basics here at all?
Many thanks in advance to all!

A lot of enterprises, however, actively avoid systems which are locked down to a particular server for very legitimate reasons. If my data center dies in the middle of the night, I sure don't want to have to call your mobile phone so that you can get to a computer, log in to the office network, and get me a new key so that I can finish my emergency failover. If I've got dozens of applications, I absolutely don't want to do that with dozens of different vendors.
It sounds like your problem, though, isn't that users are installing your software on multiple computers it's that they are accessing functionality they haven't licensed. That is generally a much easier problem to solve and doesn't require you to lock anything down to a particular machine. You can create a table LICENSED_CONTENT, for example,
CREATE TABLE licensed_content (
client_id NUMBER,
content_type VARCHAR2(30),
key RAW(128)
)In this case, KEY is, say, a hash (using the DBMS_CRYPTO or DBMS_OBFUSCATION_TOOLKIT packages if you'd like) of the client_id, content_type, and a bit of salt (i.e. a fixed string that only you know). When you sell a license to manage diamond content, you provide a script that inserts the appropriate row in the LICENSED_CONTENT table. When your application starts up, it reads the LICENSED_CONTENT table and verifies the hash before allowing users to access that type of content. This allows legitimate customers to move the software from one system to another but prevents them from accessing new functionality without a new license.
