Checks the inventory information during installation and update procedures.
sysck { -i | -u } [ -R RootPath ] [ -N ] [ -v ] [ -s SaveFile ] [ -O { r | s | u } ] -f File ProductName { tcbck Flags }
1All of the tcbck command flags are valid with this command.
Attention: The sysck command DOES NOT support checking files that are greater than 2 gigabytes. If a product needs to ship a file that is greater than 2 gigabytes, set size and checksum values in their Fileset.inventory to VOLATILE, so the sysck command will not try to access the file.
Note: All of the tcbck command flags are valid with the sysck command. This feature provides compatibility with Version 3.1. For more information on the tcbck command and a complete listing of its flags, refer to AIX 5L Version 5.1 Commands Reference.
The sysck command checks file definitions against the extracted files from the installation and update media and updates the Software Vital Product Data (SWVPD) database. The sysck command does not recognize the following special characters in file names: `, ', \, ", ^, ( ), |, {}, [], <>,and : . If a file name contains one of these characters, the sysck command fails.
The sysck command is primarily used during the installation and update of software products.
When invoked with the -i flag, the sysck command checks the attributes of an extracted file with its file definitions, updates the SWVPD, and attempts to fix some errors if they exist.
The File parameter is the name of the stanza file that contains the file definitions. An example of such a file is the /etc/security/sysck.cfg file, although the syschk command does not use this file. The sysck command checks the size, links, symlinks, owner, group, and mode attributes of a file for which the type attribute is set to FILE. When invoked with the -v flag as well as the -i flag, sysck also checks the checksum value of a file.
The sysck command updates the file name, product name, type, checksum, and size of each file in the SWVPD database.
To fix errors, the sysck command resets the attribute of the installed or updated file to the defined value in the File stanza file, except for some attributes as described in "Fixing Errors".
When invoked with the -u flag, the sysck command removes the entry from the SWVPD database for each file that is part of the software product ProductName. The sysck command also deletes any hard links and symbolic links for each file, as defined in the SWVPD database.
| acl | The access control list for the file. If the value is blank, the
acl attribute is removed. If no value is specified, the
command computes a value, according to the format described in Access Control
Lists.
This attribute should grant x (execute) access only to the root user and members of the security group. The command should setuid to the root user and have the trusted computing base attribute. |
| class | The logical group of the file. A value must be specified because it cannot be computed. The value is ClassName [ClassName]. |
| checksum | The checksum of the file. If the value is blank, the checksum attribute is removed. If no value is specified, the command computes a value, according to the format given in the sum command. The value is the output of the sum -r command, including spaces. |
| group | The file group. If the value is blank, the group attribute is removed. If no value is specified, the command computes a value, which can be a group ID or a group name. |
| mode | The file mode. If the value is blank, the mode attribute is removed. If no value is specified, the command computes a value, which can be an octal number or a string (rwx), and have the TCB, SUID, SGID, and SVTX attributes. |
| owner | The file owner. If the value is blank, the owner attribute is removed. If no value is specified, the command computes a value, which can be a user ID or a user name. |
| size | The size of the file in bytes. If the value is blank, the size attribute is removed. A VOLATILE value in the size field indicates that the file size will change (so no checksum value can be given). A NOSIZE value indicates that the file has 0 length. If no value is specified, the command computes a value, which is a decimal number. |
| target | Allows symbolic links and hard links to exist as separate stanzas in the
inventory. The target file definition refers to the full
path name of the source of the link, for example:
/etc/foo --> /usr/bar |
| type | The type of file. This value cannot be blank. If no value is specified, the command computes a value, which can be the FILE, DIRECTORY, FIFO, BLK_DEV, CHAR_DEV, LINK, MPX_DEV, and SYMLINK keywords. |
| xacl | An addition to the extended-access control list. A value must be specified as a single entry in an extended-access control list because the value cannot be computed. This attribute is valid only if the -i flag is used. For information about the format, see the acl file definition above. |
To fix errors, the
sysck command resets the attribute of the installed or updated file
to the defined value defined in the File stanza file except for the
following attributes, for which the sysck command acts as
described:
Privilege Control: Only the root user can run this command.
/usr/bin/dude.exec: class = apply,inventory,dude.rte owner = bin group = bin mode = 555 type = FILE size = 2744 checksum = "04720 3"
The installp command, sum command, tcbck command.
