Installing from a Distribution Media: How do I install software from distribution media? A setup program guides you through the installation process Following the program will make installation easy Why is it necessary to install most software? When you install software, the new software files are placed in the appropriate folders on your computers hard disk –Copies files from distribution disk –Uncompresses files –Analyzes computers resources –Analyzes hardware components and peripheral devices –Looks for any system files and players –Updates necessary system files How do I know if a software program will work on my computer? System requirements specify the operating system and minimum hardware requirements necessary for a software product to work correctly System requirements are listed on the outside of the software package. Installation Basics: What s included in a typical software package? The key ingredients necessary to install new software are –the files that contain the programs and data Usually supplied on distribution media –floppy disks –CD-ROMS –DVDs How are instructions converted to machine language? An alternative to a compiler is an interpreter, that converts one instruction at a time while a program is running –Java Year 2009Ĥ.1.2 Software Installation and Copyrights Software Installation Software Copyrights ![]() Complex flat file stage datastage example programs code#if the next Stage does not support the group column type (ie.How are instructions converted to machine language? A compiler translates all of the high-level instructions in a program as a single batch (of 1s and 0s) The resulting machine language instructions are called the object code The resulting machine language instructions are called the object code.Typical cases are that the target Stages are Complex Flat File or Sequential Stage etc. enable "Enabling all group column selection" if you would like the whole group to be propagated to the next Stage and keep the column structure.to treat group column(s) as single character column(s), redefine the group as character column with the length of the whole group.If the columns are selected, do not enable "Enabling all group column selection" if you do not want to treat the group column(s) as single character column(s).do not select columns that are not used in downstream Stages.Since the two columns are never used by the Transform Stage it keeps on running without problem. The error indicated that there is a error in schema matching between input and output. Q4: What does the error actually indicate? Note: This option can be worked around by adding a redefine column for the group column and using the group column length as the redefined column length. This option should be used with caution because all sub-colums should be character columns and no column should be variable length. If any sub-column in the group is to be used by the downstream Stages do not enable it. ![]() To treat the whole group as one character column, "Enabling all group column selection" should be checked. Q3: When should "Enabling all group column selection" be checked versus unchecked? When "Enabling all group column selection" is unchecked, an operator promotesubrecs is generated behind the scenes to promote sub columns under the group to the same level as the group columns. Q2: What happens if "Enabling all group column selection" is unchecked? When it is enabled, the whole group column will be treated as one character column. The difference is the schema generated will be different when "Enabling all group column selection" is checked. Q1: What is the difference between the two methods that has been done? Some additional information on "Enabling all group column selection" option:
