Port SCOUNIX to Linux-general Linux technology-Linux programming and kernel information. The following is a detailed description. A recent project required to port a Cabinet system originally running on the sco unix operating system to the Red Hat Linux AS platform. Now there seems to be a trend. The financial industry's systems originally running under SCO are all ready to be migrated to LINUX. The following is a brief summary of some experiences in

In SCOUNIX, the development of Device Drivers-general Linux technology-Linux programming and kernel information. The following is a detailed description. 1. Related Concepts ---- 1 device number and Device Driver ---- The device number is a number that indicates the device. These devices have special files on the system. The device number consists of the master device number and sub-device number. The high byte is the master device number and the bot

Use the doscommand to break the UNIX Administrator Password For the majority of scounix operating system administrators, one of the most common mistakes is to forget the administrator password (that is, the superuser password ). This mistake can cause extremely serious consequences. Anyone with UNIX operating system knowledge should be aware of it. However, unfortunately, there are still many mistakes. It seems that we have to blame them, but since

First, explain the Pcunix environment, the PC server can be installed on a variety of UNIX systems such as Scounix,sunsolarisx86 system, BSD system, etc., but the only application in production systems (such as postal savings, The Pcunix system of securities and certain bank-front machines, etc.) is the Scounix series, such as Openserver,unixware. Recently a UNIX introductory course for a postal system, Se

operating system does not have similar functions, there is no way to implement this system call. Worse, since POSIX Threads are not yet complete or widely supported, clone () has emerged and is often used as an alternative to POSIX Threads, many programs use it in a variety of exciting, complex, and unexpected ways. If you want people to run your binary program, try to prevent them from using system calls for specific operating systems; it is best to use standard POSIX system calls. This is a g

First, let's explain how to install a variety of UNIX systems on PC servers, such as Sco UNIX, Sun Solaris x86, and BSD systems, but the only application is in the production system, such as postal savings, securities and some front-end banking systems) are the Sco UNIX series, such as Openserver and UnixWare. Recently, I took a Unix entry-level course on a postal system. The selected system platform is the old Sco Openserver5.0.x. I believe many friends who study Linux will feel very inconveni

technology is useless to my architecture, I will not touch it even if the technology is hot. In short, learn to grasp the essence, control technology, rather than be driven by technology. When you have mastered the principles of nature, you learn everything quickly, after all are interlinked, I first see JDO, after looking at the hibernate, in fact, the two are very similar, so learn quickly, if there is a need for work, I would like to learn other Orm, then I will not feel any difficulties, t

If the maximum value has been reached, the table must be unloaded (export) and then imported into the database using the Compress extents option. Second, ORA-03106 fatal two-task communication protocol error This information indicates that an error occurred while Oracle was working on network communi

SCSI devices, 7th are SCSI cards, No. 0 is the hard drive, and 8th is also a SCSI device. The tape drive that is connected to the SCSI card cannot use these 3 numbers, generally using 5,6. 4th, line 52 is another SCSI card. 6th, 72 lines are IDE cards, respectively, connected to the hard drive and CDROM. 2, the installation of the tape drive Shutdown. Set the number on the tape drive to an idle number and connect to the SCSI connector. Reboot, a new file/dev/rmt/ctape1 will appea
