Sqlnet.ora

Hi,
1-if I rename my sqlnet.ora to sqlnet.ora_old, I can start listener otherwise not. Do you know this problem ? And the solution ?
2-with which assistant can I generate again the sqlnet.ora file ?
My DB is 10g on win XP pro.
many thanks.

Sqlnet.ora doesn't seem to be read since oci8 1.3.4

Hello,
I used to use oci8 version 1.2.3 and I wanted to update to last version (1.3.4). Everything works fine except the fact that "sqlnet.ora" does not seems to be read anymore.
I use the following string to describe my database in oci_connect: "MEN1PRD".
In sqlnet.ora there is the parameter NAMES.DEFAULT_DOMAIN which is set to "WORLD".
In the tnsname.ora I have a full definition for "MEN1PRD.WORLD".
With oci8 1.2.3, it worked but since I upgraded to 1.3.4 this is not the case anymore. I have to use the same ID in oci_connect and tnsname.org. The sqlnet.ora NAMES.DEFAULT_DOMAIN does not seem to be used anymore.
The version of php (5.2.3) is still the same, the configure options are the sames, the oracle lib is the same (9.2) and the php.ini parameters are the same too. I just changed the oci8 version.
Has anyone the same problem ? Is this a normal behaviour ? If yes, why
and is there a workaround ?
Thanks for your answers.

How to supply wallet location to OCI client for SSL connection other than sqlnet.ora

I have a oracle 11g database server and I am connecting to it through OCI client in OBIEE Admin tool. This is working fine, but now the requirement is we need to connect to an SSL enabled database.
For this I had to update the sqlnet.ora under $ORACLE_HOME/network/admin in OBIEE installation and specify the wallet location where I placed the wallet containing appropriate certificates.
The above is working fine for me. But due to certain restrictions, we cannot create this sqlnet.ora. Is there a way we can pass this wallet location through some environment variables so that sqlnet.ora is not required?
If we create a jdbc connection, we can specify the wallet location through jdbc connection properties. Is there any such equivalent for OCI based connection. I dont mind how we make the wallet location available to OCI client, so long as I dont have to create a sqlnet.ora.
Any pointers is greatly appreciated

Hi,
sqlnet.ora file is required if you want to set the wallet location to another directory by using the WALLET_LOCATION parameter.
If you do not want to use sqlnet.ora then you need to use the default wallet location.
The wallet is placed, by default, in $ORACLE_BASE/admin/<global_db_name>/wallet.
If this directory does not exist or ORACLE_BASE is not set, the default location is: $ORACLE_HOME/admin/<global_db_name>/wallet

Sqlnet.ora file 11.5.10.2

Hi,
I always disabled or commented the 2 lines sqlnet.ora file to accept all database connections...
tcp.validnode_checking=yes
tcp.invited_nodes=
I commented the above lines in sqlnet.ora file and bounced the listener..now i am able to connect to the database...
When ever I run the autoconfig in database tier..... these 2 lines are going to be uncommented...
how we can do this for permenant for checking the above 2 lines sqlnet.ora file..
do we need to add any custom context variables in Context file..if it is so..how can we do it..please help me in this regard....

tcp.validnode_checking=yes
tcp.invited_nodes= <list your applications tier nodes here>
These actually ARE recommended in Production. Basically what you're saying by setting these is that the SQL*Net Listener for the database will ONLY talk to these known hosts. This prevents some random person from connecting directly to your database from a PC somewhere.
The downside here is that if you have a large number of users who use a client-side tool (like ADI or Discoverer), then you'll have to list their IP addresses here. This can be quite difficult in a DHCP-enabled environment.
The way autoconfig works, it basically replaces any autoconfig managed files whenever it runs (which is why your customizations get clobbered).
So, in situations where there isn't a context variable that you can update, you'll have to make a custom template.
When autoconfig runs, it checks first for the existence of the custom template (and validates that it isn't based on an older version than the currently installed one) and will use that instead of the delivered one.
Simple way to do a custom template:
1) Identify the template being used (Database tier, it'll be under $ORACLE_HOME/appsutil somewhere... Apps tier it's generally under $AD_TOP/admin/template or $FND_TOP/admin/template).
2) Create a "custom" directory under the "template" directory where your template lives.
3) Copy that template into the "custom" directory.
4) Edit this copy.

Questions on sqlnet.ora, listener.ora files in RAC environment.

Experts,
I've some confusion with below files in RAC environment.
sqlnet.ora
listener.ora
These files are available in two locations: <GRID_HOME> & <DB_HOME>.
My questions:
1. Why do we have two versions of files ?
2. When I query lsnrctl status from BOTH the homes, it says it is using listener.ora from <GRID_HOME> as shown below.
Listener Parameter File D:\app\11.2.0\grid\network\admin\listener.ora
3. What is the use of files which are in <DB_Home>
4. If you make some changes to listener using "Netmgr" tool, we expect it will update listener.ora in <GRID_HOME>. Interestingly, it is changing the contents of listener.ora in <DB_HOME> .
Can anyone please clarify it ?
Thanks in advance.

1. Why do we have two versions of files ? In the past, the CRS s/w did not include ASM (ASM did not provide support for cluster voting and registration disks). Thus the networking components such as SQL*Net and the Listener were not part of the CRS installation.
With Grid Infrastructure, ASM supports cluster voting and registration disks and is recommended to be used for that (as oppose to the old style of raw disks or using an external cluster-based cooked file system like <i>ocfs</i>). And with ASM comes the SQL*Net networking layer and s/w (such as the Listener). As ASM ships with Grid Infrastructure, it now also includes the same networking layer as what the RDBMS installation will. Thus both <GRID_HOME> and <DB_HOME> will contain the same networking components.
However, only a single Listener is for example needed. And that can only run from a single base location. So for operational use, only one version will be actively in use.

Tnsnames.ora, sqlnet.ora & listener.ora files are not exit

DB version: 10.2
Hello All,
I just joined the project and notice tnsnames.ora, sqlnet.ora & listener.ora files are not exit under $ORACLE_HOME/network/admin.
But still we can connect to the database,
From command prompt or via enterprise manager studio from client site.
Any idea?
OR
what is the best way to create above files in the existing database?
DN

tnsnames.ora and sqlnet.ora are client side files, listener.ora and sqlnet.ora are server side files.
Listener.ora need not exist if using defaults and dynamic registration of services. It may be possible to cope without all those files, depending on the environment.
Is the database on the local or remote computer and how are you connecting (from sqlplus)?
Maybe you have a tnsnames.ora somwhere else? (Try using find command) Maybe TNS_ADMIN is set?

Connect with ldap.ora and sqlnet.ora

Hi
I am trying to connect Raptor to 9i oracle server. Our server connects using ldap.ora and sqlnet.ora files. I looked at some threads about this issue but do not understand how to connect. Is there a step by step instruction for connecting this way?
Thanks
DH

Hi VRamirez,
That's a pretty cool workaround. I'm sorry to hear it didn't work perfectly.
Here is the "low tech" workaround anyone can use -
From the %ORACLE_HOME% where your sqlnet.ora is, run %ORACLE_HOME%\bin\tnsping eg.
C:\> tnsping oracle.world

Now copy the (DESCRIPTION=...) and paste it into the advanced TNS info tab in the Connections dialog. This works for me for everything but RAC TNS aliases which have load balancing and failover configured -- the advanced TNS info tab chokes on those. For such connections, I was able to use the JDBC string.

Disadvantages of SQLNET.EXPIRE_TIME in SQLNET.ORA

Hi,
Could any body tell me please what would be side effects and disadvantages of using SQLNET.EXPIRE_TIME parameter in the sqlnet.ora file when there are frequent network timeouts?
Does Oracle recommends network problems should be resolves or SQLNET.EXPIRE_TIME parameter is harmless to keep connectivity between clients and server?
Thanks

Hi,
it has affects on pmon, which maybe cleans up resources which are held by the "dead" shadow process. PMON will clean up after the expire_time, when there is no connection.
"Negative" effects... i don't have seen really negative affects... the network traffic maybe increase (depends on your amount of connections).. but this should not be a problem.

Stefan

Database connectivity requiring oracle wallet, tnsnames.ora, and sqlnet.ora

We have a new datasource that I need to write a report against. In order to access the db, I have to install an Oracle wallet on my pc that contains a certificate. I then have an entry in the sqlnet.ora file that references this wallet, and I have an entry in my tnsnames file. I wrote a report successfully on my pc. We then have our Business Objects installation on a Sun Solaris machine with Unix. We installed the wallet, added the sqlnet.ora entry, and the tnsnames.ora entry. I am able to connect to the db from the unix command prompt by typing sqlplus username@dbname successfully. However, when I place my Crystal Report in Bus. Obj. I cannot get it to work. I go to the CMC, select the report, choose Process, Database. I am entering Use custom database logon info and choosing Oracle as my database driver. I then enter the tnsnames entry into the server and enter my username and password and check the use use same database logon as when report is run. I get the error The database logon information for this report is either incomplete or incorrect. I'm guessing the report is not using the certificate in the wallet when it is trying to log on, but I'm not sure. Does anyone have any suggestions or experience with this? Thanks in advance for any help.

Hi Angie,
you should install the 32bit Oracle driver on your Solaris machine and adjust the LD_LIBRARY_PATH environment variable (in the profile of the BOBJ installation user) to point to the path of the 32bit libraries of your Oracle driver.
BOBJ is not a native 64bit software and can therefore work only with the 32bit versions of the database drivers.

Stratos

Path of Sqlnet.ora and Tnsnames.ora

Hi all
Why I have one
Sqlnet.ora
in
C:\ORAWIN95\NETWORK\ADMIN
and
one in
C:\ORAWIN95\NET80\ADMIN
and
Tnsnames.ora
in
C:\ORAWIN95\NET80\ADMIN
and
C:\ORAWIN95\NETWORK\ADMIN
and
C:\ORAWIN95\NET80\TNSAPI
why they are duplicated?
thanks
Sobrinho

It looks like you have (or had) multiple versions of SQL*Net.
Oracle 8 put everything in %oracle_home%\net80 while Oracle 7 and 9 use %oracle_home%\network

SQL query to find sqlnet.ora parameters

Hi All,
I am working 11g RAC /solaris 9
I want have sql query to find values of sqlnet.ora parameters
May be values of SQLNET.INBOUND_CONNECT_TIMEOUT
SQLNET.SEND_TIMEOUT, SQLNET.RECV_TIMEOUT
Thanks
raj

The sqlnet.ora file is the profile configuration file. It resides on the client machines and the database server.
Profiles are stored and implemented using this file. The database server can be configured with access control parameters in the sqlnet.ora file.
These parameters specify whether clients are allowed or denied access based on the protocol.
The sqlnet.ora file enables you to do the following:
Specify the client domain to append to unqualified names
Prioritize naming methods
Enable logging and tracing features
Route connections through specific processes
Configure parameters for external naming
Configure Oracle Advanced Security
Use protocol-specific parameters to restrict access to the database
By default, the sqlnet.ora file is located in the ORACLE_HOME/network/admin directory. The sqlnet.ora file can also be stored in the directory specified by the TNS_ADMIN environment variable.
You can not query on this file sqlnet.ora as tnsnames.ora file.

The importance of SQLnet.ora file

DB version:10gR2
I have seen databases where SQLnet.ora file is absent or an SQLnet.ora file with most of the entries commented out like
NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)
#SQLNET.EXPIRE_TIME=700
# New parameter for 10.2
#SQLNET_INBOUND_CONNECT_TIMEOUT=120I have two questions
1. If you were asked to set the parameters for SQLNET.ora file for an OLTP database, what would your settings be?
2. Is it absolutely necessary to have an SQLNET.ora file in a 'production quality' Database?
Edited by: Citizen_2 on Feb 18, 2009 2:59 AM
Corrected the spelling of SQLnet.ora in subject line

Hi,
SQLNET.ORA can be used for different purposes,
first to identify the method to connect from client like tnsnames
Second it can be used to bypass the network layer by setting the parameter automatic_ipc=on
Third, we can set to check the client whether its active after certain interval.
If sqlnet.ora is not there, then it will take the default values.
Thanks
