Q: Solaris7 is 64-bit, does it mean I can't use it on the previous machine (32-bit)?
A: Not, Solaris7 still supports 32-bit cores of Sun4C, Sun4M, Sun4D or even Sun4u systems.
Q: Why do you have to make a file system synchronization before shutting down?
A: If you do not make a corresponding file system synchronization in front of the disk, you will have problems with the validity and consistency of the file system, which will cause the system to be unable to start.
Q: What should I determine the disk's Free HOG area?
A: Free hog is a partition of the disk, which creates a disk space yourself, usually the corresponding directory is / home. The size of the partition cannot be directly defined, but is determined by the system based on the size of the other partition and the total space of the disk.
Q: How to convert a single user and multiple families?
A: Under the Solaris system, the single user is converted to a multi-user to press CTRL and D to simultaneously; the 'INIT S' or 'Reboot-S' command can be converted to a single user in the multi-user status.
Q: What should I do if I use a drive pop-up button?
A: You can manually remove the disk cartridge. Proceed as follows:
(1) Turn off the system:
(2) Place the power switch to OFF:
(3) Plug in the small empty space in the upper right, then press the disk, and then pop up. If the disk is blocked by foreign matter, the disk can be clamped with a forceps.
Q: What is the architecture of the Sun workstation?
A: When you install or use a system disk to boot your system, you often need to know the nuclear architecture of the workstation. The nuclear architecture corresponding to the SUN different types of workstations is:
Ultrasparc series nuclear architecture is Sun4u;
SPARCSTATION 5/10/20 nuclear architecture is Sun4m.
The SparcStation 1/1 / Slc / IPC / IPX / 2 core architecture is Sun4.
Q: What is PATCH?
A: When there is a software development and commercialization software, the software often has just packaged or sold several copies, and it is found to have a mistake, but the error is not fatal. Based on the above reasons, the software developer will be picked up for the original software and make a program, which is called Patch (patch).
Q: Is I / O of the 64-bit file system when using a database application like Oracle?
A: Oracle is installed on the original disk, the speed is the fastest, it does not improve the feature of accessing the 64-bit file system speed.
Q: Which is better for sparc and pentium?
A: The sparc and pentium we have discussed refer to SPARC-based UNIX servers and Pentium-based UNIX servers. I think SPARC-based Unix servers are better, it is faster, more reliable, stronger, and is the mainstream of the market.
Q: Why can't I load the driver after upgrading to Solaris7?
A: If you run a 64-bit operating system, then the 32-bit driver will not be loaded. The system will fail when loading the core calling the driver. Solaris7 does not provide support for illegal drivers: The system will give corresponding error messages in this case.
Q: Why can't IFCONFIG command to find a network interface?
A: ifconfig command can only identify the network device (i.e., if /etc/hostname.ifn exists) when starting. Can perform the following command: ifconfig ifn plumb
Q: Why do I have an error message when installing Solaris2.5 or Solaris2.6 on U10 (or U5)?
A: Solaris 2.5 or Solaris 2.6 does not contain support for hardware structures (U10 or U5) using the IDE bus when introduced. So install it on U10 (or U5), an error occurs. Therefore, you need to use a random environment before installation, first boot the machine, follow the system prompt to continue installing Solaris2.5 or Solaris2.6.
Q: Where to find patch?
A: can be
Http://sunsolve.sun.com/pub-cgi/show.pl?target=patches/patch-access finds the recommended PATCH.
Q: What is the characteristic of the 64-bit operating system?
A: The main difference between the 64-bit operating system and the 32-bit operating system has three aspects:
Higher precision
Larger data support
More virtual address space
Q: What is RAS?
A: RAS is Reliability, Availability and ServiceAbility.
Reliability refers to the time when the system is running. The usual calculation method is Mean Time Between Failures (MTBF);
Availability refers to the available time of the system. The usual calculation method is Percentage Of Uptime.
Serviceability refers to the maintenance time of the system. The usual calculation method is Mean Time to Repair.
Q: What language supports 64-bit system?
A: ANSI C, K & R C, ANSI C , Fortran 77, Fortran90
