Oracle Odbc Driver Configuration Fetch Buffer Size
Oracle Call Interface (OCI) is the comprehensive, high performance, native C language interface to Oracle Database for custom or packaged applications.
Buffer Size specifies the size, in bytes, allocated to receive fetched data. The driver optimizes fetching so that one fetch from the Oracle Server returns enough rows to fill a buffer of the specified size.
OCI is highly reliable. Oracle tools such as SQL*Plus, Real Application Testing (RAT), SQL*Loader, and Data-Pump all use OCI. OCI provides the foundation on which other language-specific interfaces such as Oracle JDBC-OCI, Oracle Data Provider for Net (ODP.Net), Oracle Precompilers, Oracle ODBC, and Oracle C++ Call Interface (OCCI) drivers are built. OCI is also used by leading scripting language drivers such as node-oracledb for Node.js, PHP OCI8, ruby-oci8, Perl DBD::Oracle, Python cx_Oracle, and the statistical programming language R's ROracle driver.
Oracle 32 Bit Odbc Driver
A broad range of customers including Fortune 500 customers and ISVs develop high performance applications directly in OCI.
Oracle Odbc Driver Configuration Fetch Buffer Size
OCI libraries are included by default in Oracle Database 18c. OCI is also in the lightweight Oracle Instant Client, allowing ISVs and customers to quickly install and deploy OCI applications and tools. See the Oracle Instant Client page for more information.
Recently a classic ASP app that interfaces with SQL and Oracle was migrated from windows server 2003 (IIS6) to IIS 8.5 windows server 2012R2. Users are inconsistently getting an error when a connection opens up to Oracle, but not for SQL. Microsoft OLE DB Provider for ODBC Drivers error '80004005' MicrosoftODBC Driver Manager Driver's SQLAllocHandle on SQLHANDLEENV failed.This is being thrown on 'cn.open' below Set cn = server.CreateObject('ADODB.Connection') cn.ConnectionString = strOracleConnect cn.open The server is using Oracle11g 64 bit driver with default ODBC settings. Fetch buffer size 64000, LOBs enabled, cache buffer size, with failover enabled (10/10). Each time it is reported by a user by the time I get to their desk or try it myself I can't reproduce. 98% of the time it works without issue. Any help or suggestions would be appreciated, I feel this has to be a configuration problem but I can't seem to gain any ground on this and it doesn't help that I can't reproduce it.
