To Create or Remove Paths Among Tables
A concatenation path or table path is a property of a table. If a table
does not contain information requested by an NIS+ principal, but it has a
concatenation path, NIS+ searches the other tables in the concatenation
path until it finds the requested information or comes to the end of the
path. NIS+ does not follow paths recursively; that is, if one of the tables
in the concatenation path has its own concatenation path, NIS+ will not
follow it.
Do not use table paths if your server is running in NIS compatibility
mode. NIS clients cannot follow table paths.
• To find out whether a table has a concatenation path, issue this
command:
niscat -o tablename
The Search Path line in the output is the table’s concatenation path.
• To create or modify a concatenation path for a table, issue this
command:
nistbladm -u -p othertable:othertable... tablename
The following example creates a path from passwd.Sales.Wiz.Com.
to passwd.Eng.Wiz.Com. It causes NIS+ to search the passwd table
of the Eng.Wiz.Com. domain if it fails to find requested information
in the passwd table of the Sales.Wiz.Com. domain.
nistbladm -u -p passwd.Eng.Wiz.Com. passwd.Sales.Wiz.Com.
• To remove a concatenation path from a table, issue this command:
nistbladm -u -p ”” tablename
The following example removes the concatenation path from the
passwd table in the Sales.Wiz.Com. domain:
nistbladm -u -p ”” passwd.Sales.Wiz.Com.
You can also create NIS+ links to other tables, but links are slower than
paths and are not recommended. Type man 1 nisln for more
information.
You need modify permission for a table to change its concatenation path.
For more information, type man 1 nistbladm at the HP-UX prompt.
