Solve the problem that the TAR file cannot be large in the Solaris system.

During field work, large files (larger than 8 GB) in the Solaris system cannot be tar, especially when the cold backup of the database is larger than 8 GB of data files, the database backup fails.

First, for example, to back up a data file larger than 8 GB to a tape, you must change tar CVF/dev/RMT/0 to tar cvfe/dev/RMT/0, add an uppercase letter e to support operations on files larger than 8 GB tar.

2. Download The tar-1.13.19-sol8-sparc-local.gz toolkit on the http://www.sunfreeware.com website and install it with pkgadd after unzipping. Because the tar executable file is stored in/usr/local/bin, You need to modify the. profile file. Put/usr/local/bin at the beginning of the PATH environment variable, so that the system will first call the executable file under/usr/local/bin when calling the tar command.
