Migrating Oracle from Big Endian to Little Endian Platorm

Hi, We are trying to migrate an oracle database from Sun Solaris (SunOS 5.9 Generic_118558-28 sun4u sparc SUNW,Ultra-60) to Linux 2.6.18-53.1.19.el5 #1 SMP Tue Apr 22 03:01:10 EDT 2008 x86_64 x86_64 x86_64 GNU/Linux which is basically a Big Endian to Little Endian conversion. We shutdown... (3 Replies)

NAME
inet - Internet protocol family SYNOPSIS
#include <sys/types.h> #include <netinet/in.h> DESCRIPTION
The Internet protocol family is a collection of protocols layered atop the Internet Protocol (IP) transport layer, and utilizing the Inter- net address format. The Internet family provides protocol support for the SOCK_STREAM, SOCK_DGRAM, and SOCK_RAW socket types; the SOCK_RAW interface provides access to the IP protocol. ADDRESSING
Internet addresses are four byte quantities, stored in network standard format: layed out as highest to lowest order bytes in memory or ``Big Endian'' (the VAX is word and byte reversed, or ``Little Endian''; the PDP-11 is byte reversed within each word, or ``Middle Endian''). The include file <netinet/in.h> defines this address as a discriminated union. Sockets bound to the Internet protocol family utilize the following addressing structure, struct sockaddr_in { short sin_family; u_short sin_port; struct in_addr sin_addr; char sin_zero[8]; }; Sockets may be created with the local address INADDR_ANY to effect "wildcard" matching on incoming messages. The address in a connect(2) or sendto(2) call may be given as INADDR_ANY to mean ``this host.'' The distinguished address INADDR_BROADCAST is allowed as a shorthand for the broadcast address on the primary network if the first network configured supports broadcast. PROTOCOLS
The Internet protocol family is comprised of the IP transport protocol, Internet Control Message Protocol (ICMP), Transmission Control Pro- tocol (TCP), and User Datagram Protocol (UDP). TCP is used to support the SOCK_STREAM abstraction while UDP is used to support the SOCK_DGRAM abstraction. A raw interface to IP is available by creating an Internet socket of type SOCK_RAW. The ICMP message protocol is accessible from a raw socket. The 32-bit Internet address contains both network and host parts. It is frequency-encoded; the most-significant bit is clear in Class A addresses, in which the high-order 8 bits are the network number. Class B addresses use the high-order 16 bits as the network field, and Class C addresses have a 24-bit network part. Sites with a cluster of local networks and a connection to the DARPA Internet may chose to use a single network number for the cluster; this is done by using subnet addressing. The local (host) portion of the address is further subdivided into subnet and host parts. Within a subnet, each subnet appears to be an individual network; externally, the entire cluster appears to be a single, uniform network requiring only a single routing entry. Subnet addressing is enabled and examined by the following ioctl(2) commands on a datagram socket in the Internet domain; they have the same form as the SIOCIFADDR command (see intro(4N)). SIOCSIFNETMASK Set interface network mask. The network mask defines the network part of the address; if it contains more of the address than the address type would indicate, then subnets are in use. SIOCGIFNETMASK Get interface network mask. SEE ALSO

The Internet protocol support is subject to change as the Internet protocols develop. Users should not depend on details of the current implementation, but rather the services exported. 4.2 Berkeley Distribution August 1, 1987 INET(4F)
