  • RACF Tips Volume 3, Issue 1, January 2009
    Volume 3 Issue 1 IPS RSH RACF T January For Administrators, Auditors, and Analysts 2009 Specifying a Replacement ID used to change a file's attributes for Program Control, APF Authorized, and Shared Library. with IRRRID00 . To generate commands to delete an ID and all references to it, use RACF's IRRRID00 utility. You simply enter the ID in the SYSIN DD Temporary Access with statement of the IRRRID00 job like so: CONNECT REVOKE(date) //SYSIN DD * USERX You may occasionally need to permit a user temporary access to a resource. One way to do If USERX is the owner of a profile or connect, so is to grant a group access to the resource IRRRID00 generates commands like: and connect the user to that group with a revoke date. The command to set the connect revoke CONNECT RDSADM GROUP(RACFSTC) OWNER(?USERX) date would look something like this: In these cases, you need to change ?USERX to CONNECT USERA GROUP(TEMPACC) REVOKE(1/20/09) a valid replacement ID. This can be done manually or with ISPF EDIT CHANGE. On the date specified with the revoke, RACF will no longer allow the user to have the access Alternatively, you can tell IRRRID00 which permitted to the group. If you want to remove the replacement ID to use when it builds the revoke date but leave the connect intact, enter: commands. If, for instance, you want to replace every occurrence of USERX with USERJ, enter CONNECT USERA GROUP(TEMPACC) NOREVOKE the following in the SYSIN DD: A banking client of ours used this capability to //SYSIN DD * govern access to APF-authorized libraries.

  • ARM Code Development in Windows
    ARM Code Development in Windows By: Ali Nuhi This guide will describe how to develop code to be run on an embedded Linux system using an ARM processor (specifically the OMAP3530). Environment The Cygwin bash shell will be the environment used for code development. Download it from the below link. http://cygwin.com/install.html READ THE SITE. Download setup.exe and choose the packages you want to install. Some helpful packages to download are: -gcc4-core,g++ etc. (for c and c++ compiling of normal programs) -git core files and completion (version control system) -wget (utility to download files from the internet via HTTP and FTP) -VIM (text editor) -Xemacs (another text editor, better than vim) -nano (simple command line text editor) If you still use windows notepad for writing code please atleast upgrade to notepad++. Toolchain We will be compiling and creating files using CodeSourcery g++ lite toolchains. This is a modified version of GCC which will create files specifically for ARM target systems. Download this at: http://www.codesourcery.com/sgpp/lite/arm/portal/release1803 Download the Windows installer and execute. You can let it install as is unless you have some other install scheme on your computer. I highly recommend reading the getting started pdf that comes with CodeSourcery. Once it’s fully installed open up Cygwin and execute the below lines. $ export CYGPATH=cygpath $ export CYGPATH=c:/cygwin/bin/cygpath If you installed Cygwin to another directory then you must edit the second line. To use the compiler type the following and hit tab twice to see all of the possible options you have.

  • 11.7 the Windows 2000 File System
    830 CASE STUDY 2: WINDOWS 2000 CHAP. 11 11.7 THE WINDOWS 2000 FILE SYSTEM Windows 2000 supports several file systems, the most important of which are FAT-16, FAT-32, and NTFS (NT File System). FAT-16 is the old MS-DOS file system. It uses 16-bit disk addresses, which limits it to disk partitions no larger than 2 GB. FAT-32 uses 32-bit disk addresses and supports disk partitions up to 2 TB. NTFS is a new file system developed specifically for Windows NT and car- ried over to Windows 2000. It uses 64-bit disk addresses and can (theoretically) support disk partitions up to 264 bytes, although other considerations limit it to smaller sizes. Windows 2000 also supports read-only file systems for CD-ROMs and DVDs. It is possible (even common) to have the same running system have access to multiple file system types available at the same time. In this chapter we will treat the NTFS file system because it is a modern file system unencumbered by the need to be fully compatible with the MS-DOS file system, which was based on the CP/M file system designed for 8-inch floppy disks more than 20 years ago. Times have changed and 8-inch floppy disks are not quite state of the art any more. Neither are their file systems. Also, NTFS differs both in user interface and implementation in a number of ways from the UNIX file system, which makes it a good second example to study. NTFS is a large and complex system and space limitations prevent us from covering all of its features, but the material presented below should give a reasonable impression of it.
