daily basis, across the globe. The proven reliability and growing popularity of Linux has many major server application vendors moving to support Linux. IBM has ported the DB2 database to Linux, Oracle has ported its database offering, and enterprise resource planning (ERP) solution providers are porting applications to Linux.The largest cost involved in any change of technology is in the conversion from one platform to another. Costs to consider including training, down time, data transfer, and testing. These costs are usually much larger than the initial cost of the hardware and software.In converting from NT to Linux it would be advisable to run a parallel conversion, running both OSs at the same time. This method allows you move the processes one by one, comparing the results and allows a fall back to the old system if problems are encountered. A variation of this is setting up Linux as a new server that handles new functions. This method eliminates the costs of converting existing functions from NT to Linux and allows adaptation to Linux to proceed at its own pace. After Linux has been established as a network solution, former NT processes can be moved without the steep learning curve..Server OS summaries Caldera OpenLinux(TM) eServer 2.3 Web-based administration interface to configure DNS, Samba, NFS, local/remote file systems Tunable kernel parameters are set to meet server requirements Hardware-level and software-level RAID is compiled into the kernel Disk quota support is enabled by default Compiled and optimized for Pentium Pro or better processors Additional PAM (Pluggable Authentication Modules) are included to enhance basic system security Option to build the kernel to support up to 4 GB of physical RAM Raw I/O support for enhanced database performance Dynamic file descriptors to support enterprise-level database/application performance ᠒...
