Direct NFS Client integrates the NFS client functionality directly in the Oracle software to optimize the I/O path between Oracle and the NFS server. This integration can provide significant performance improvements.
Direct NFS Client supports NFSv3, NFSv4, NFSv4.1, and pNFS protocols to access the NFS server. Direct NFS Client also simplifies, and in many cases automates, the performance optimization of the NFS client configuration for database workloads.

If Oracle Database cannot connect to an NFS server using Direct NFS Client, then Oracle Database connects to the NFS server using the operating system kernel NFS client. When Oracle Database fails to connect to NAS storage though Direct NFS Client, it logs an informational message about the Direct NFS Client connect error in the Oracle alert and trace files.
Oracle recommends using the latest 19c Release Update of Oracle Instant Clientor Oracle Database Client. This is a Long Term Release.
Alternatively you can use the latest 21c Release Update if you require clientfeatures introduced in this Innovation Release.
DigiCert retired the Organizational Unit (OU) field for all public TLS/SSLcertificates to comply with industry standards as of August 2022. This meansthat public TLS/SSL certificates issued by DigiCert will no longer have an OUfield. Refer to MOS note 2911553.1for details.
To avoid disruption to applications connecting to Oracle Autonomous Database onShared Exadata Infrastructure (ADB-S) during the server side certificatechange, you must use hostname based matching of the server certificate.
The following versions of Oracle Instant Client automatically support hostnamebased matching:
Versions: 18.19 (or later), 19.2 (or later), 21 (base release or later)
Oracle Call Interface (OCI), Oracle C++ Call Interface (OCCI) or ODBCapplications must use one of the above client versions.Oracle Database drivers based on Oracle Instant Client or Oracle DatabaseClient (e.g ODPI-C, python-oracledb Thick mode, cx_Oracle, node-oracledb,godror, PHP OCI8, PHP PDO_OCI, ruby-oci8, ROracle, and rust-oracle) must usethe driver with a compatible client version from the list above.An additional step is required if you have changed the ADB-S connection string.
ADB-S connection strings contain a hostname "...(HOST=xyz)..." which depends onthe region. For example, in the Chicago region the hostname would be"adb.us-chicago-1.oraclecloud.com". If you have replaced the default hostnamewith an IP address or a custom hostname, then hostname based DN matching willfail. The solution is to add a new entry to your /etc/hosts file using theoriginal ADB-S domain suffix. Your connection string should then use this newname. For example an entry "localtunnel.adb.us-chicago-1.oraclecloud.com"could be created and used.
Version 11.2.0.4 is not publicly available, it can be downloaded from support.oracle.com - including the full client. In order to log in there, you need an account associated with a valid CSI number (support contract).
The list below is a list of known bug fixes for Direct NFS. These fixes are recommended for customers using Direct NFS client based on the configuration details described in the list below. Some of these bugs may also be applicable to older releases.
There is a small performance degradation for multiblock reads when using Direct NFS as Direct NFS fragments the reads into multiple single block reads. These reads are not fragmented if the OS NFS client is being used.
Hm, so where is your tnsnames located then?
In a location specified by tns_admin?
in same folder as Toad.exe?
Either of the above should work...so...is it somewhere else?
I am wondering if it is in a client that you are not using.
It's supposed to only find the tnsnames.ora in the above-named locations in no-client mode. You got lucky on the connection. The message on the tnsnames editor click is correct. workaround: add the tns_admin env variable and point to the client's network\admin location (or move it somewhere else, to be shared by all clients and no-client mode)
It's been long that I had downloaded and installed the oracle client. Please help and advise me to direct me to the link to download the complete oracle client installation 19c? Basically we need to install oracle client to support our end users and developers to be able to use a SQL developer and SQL*plus to connect to the database.
dotConnect for Oracle, like most of applications that work with Oracle,uses Oracle Call Interface (OCI) to connect to Oracle database server. This isusual way to develop Oracle applications with a third-generation language.However, it requires Oracle Client software installed on workstation that isthe cause of additional expenses for installation and administration. Moreover,.NET security settings may restrict usage of unmanaged libraries, which makesimpossible to use the client software, for example, on ASP.NET servers. Startingwith dotConnect for Oracle 3.0, these problems can be eliminated by using the Direct mode ofconnecting to server.
Data Encryption is an Oracle Advanced Security service that encrypts message data between client and server. dotConnect for Oracle enables data encryption in the Direct mode depending on the DirectUtils.EncryptionLevel property.
Data integrity is an Oracle Advanced Security service that ensures that the data, transmitted between client and server, is not modified in between and is not retransmitted multiple times by an attacker. dotConnect for Oracle enables data integrity in the Direct mode depending on the DirectUtils.DataIntegrityLevel property.
The Direct mode has some limitations: Connect using the TCP/IP protocol only. Oracle TimesTen is not supported. While the OCI Mode fully supports RAC, Failover, Load Balancing, the Direct Mode supports RAC with Connect Time Connection Failover (CTCF) only. The OracleLoader class uses Array Binding instead of the direct path load interface in the Direct mode, and has limited functionality. Please note that we don't guarantee dotConnect for Oracle compatibility in the Direct mode with all Oracle servers and in every network. We have tested it with all versions of Oracle server for Windows and Linux since 7.3 in local network. Other platforms may cause some incompatibility issues. The Direct mode does not support NLS conversion on client side. The Direct mode does not support connecting using OracleCredential. Transparent Application Failover not supported Statement caching is not available. Proxy authentication features are not available. LDAP authentication is not supported in the Direct mode. Passing sharding key values when connecting for performing single-shard queries to a sharded database is not supported in the Direct mode. Implicitly returned resultsets (via DBMS_SQL.RETURN_RESULT introduced in Oracle 12c) are not supported. Oracle Transaction Guard is not supported. The OracleDatabase class is not supported in the Direct mode. The OracleConnection.PurgeStatementCache method works only in OCI mode. The OracleConnection.HAEvent is supported only in the OCI mode and only for Oracle Client 10g and higher. A number of OracleXml properties and methods are not supported in the Direct mode. See the property descriptions to determine whether they are supported in the Direct mode. AsyncNotification in Advanced Queuing is not supported in the Direct mode.
No matter what I try, when I start Toad 12.6, I get the error: "No valid Oracle clients found. You need at least one 64-bit client properly configured." In the install, I used a downloaded win64_11gR2_client.zip file and it sure looked like it installed.
I've tried installing the client directly, and I get an error about the path too long. I ignore the error and the install dies. From research, it has said that uninstalling the 32 bit client is the way to go. It doesn't appear to be the way to go.
Here's what worked, although I don't know if it's a good answer or not. I had someone who could log in as an admin on my pc do the Oracle client install. In other words, if you're not a full admin on your machine, it may fail, and not tell you why.
At Indiana University, to download the Oracle client for Windows, UITS recommends downloading the client directly from Oracle's website. This requires a valid OTN (Oracle Technology Network) username and password. If you do not have a valid OTN username and password, go to Create Your Oracle Account and follow the on-screen instructions.
Oracle Direct NFS (dNFS) is the NFS client functionality directly integrated into the Oracle RDBMS server. Oracle dNFS makes the task of configuring an Oracle database on NAS storage like FlashBlade much simpler in comparison to Standard NFS (aka Kernel NFS).
If you intend to use the Thick mode, then you must callinit_oracle_client() in the application before any standaloneconnection or pool is created. The python-oracledb Thick mode loads OracleClient libraries which communicate over Oracle Net to an existing database.The Oracle Client libraries need to be installed separately. SeeInstalling python-oracledb. Oracle Net is not a separate product: it is how theOracle Client and Oracle Database communicate.
Connect Descriptor Strings are commonly stored in a tnsnames.ora file and associated with a Net Service Name. This name can beused directly for the data source name parameter dsn oforacledb.connect() and oracledb.create_pool(). For example,given a file /opt/oracle/config/tnsnames.ora with the following contents:
More options for how python-oracledb locates tnsnames.ora files is detailedin Optional Oracle Net Configuration Files. Note in python-oracledb Thick mode, the configurationdirectory must be set during initialization, not at connection time.
Database Resident Connection Pooling (DRCP) enables database resourcesharing for applications which use a large number of connections that run inmultiple client processes or run on multiple middle-tier application servers.By default, each connection from Python will use one database server process.DRCP allows pooling of these server processes. This reduces the amount ofmemory required on the database host. The DRCP pool can be shared by multipleapplications.
