prebind - prepare frequently executed programs for faster startup SYNOPSIS
file] [path-list] DESCRIPTION
prepares some frequently executed programs for faster startup using (see fastbind(1)), and updates the IPD database for the modified files. Many frequently used commands such as etc. are so short lived that the program startup time takes up a major part of the total run time of each instance. In user-space, a big chunk of startup time could be spent in the dynamic loader, dld.so(5), in resolving the references among the program and its shared library dependencies. This startup overhead can be avoided using Patch level changes affecting related shared libraries (e.g. libc) can obsolete the information stored in an executable. So must be invoked after each such change, to ensure consistent levels of performance. As writes symbol resolution information into the executable, the metadata of the software product that provides the executable must be updated to reflect the changes. facilitates the use of It invokes on some executables known to be frequently used on HP-UX systems and updates the IPD database using see swmodify(1M). By default, operates on a pre-defined list of executables. Users can also specify an alternate list of executables by providing it in a file or as a path-list on the command line. For complete details, refer to the whitepaper at Options supports the following option: Prints the usage information. Prints a preview of commands that will be invoked, without actually invoking them. Removes information from the specified (or default) list of executables. Reads the list of executables from file. Arguments can read a list of executables either from the command line or from a file. Each command-line argument or each line in the file will be considered as the full path to an executable on which is to be invoked. Lines beginning with a pound character in the file will be consid- ered as comments and ignored. WARNINGS
uses (see swlist(1M)) to retrieve software product information and so may take a long time to complete, depending on the system software configuration. It is recommended to be used only after patch changes that may affect executables of interest. needs to be run with appropriate privileges as required to write to the executables and to run The executables must be writeable. RETURN VALUES
returns the following values: Successful completion. Failure. An error has occurred. FILES
By default, acts on the following files: While is yet another frequently used executable that can benefit from it is almost always in use and including it in the default list would generate errors. It is recommended that be run mannually on this executable when it is not in use (such as from a root shell, with no users logged in). All these executables depend on and some other similar shared libraries, so it is recommended that be run whenever any of the files men- tioned above are changed. AUTHOR
