=head1 DESCRIPTION
|
|
|
|
The tabdump command displays the header and all the rows of the specified table in CSV (comma separated values) format.
|
|
Only one table can be specified. If no table is specified, the list of existing
|
|
tables will be displayed.
|
|
|
|
=head1 OPTIONS
|
|
|
|
=over 10
|
|
|
|
=item B<-?|-h|--help>
|
|
|
|
Display usage message.
|
|
|
|
=item B<-d>
|
|
|
|
Show descriptions of the tables, instead of the contents of the tables. If a table name is also specified, descriptions of the columns (attributes) of the table will be displayed. Otherwise, a summary of each table will be displayed.
|
|
|
|
=item B<-n>
|
|
|
|
Shows the most recent number of entries as supplied on the -n flag from the auditlog or eventlog table.
|
|
|
|
=item B<-f>
|
|
|
|
File name or path to file in which to dump the table. Without this the table is dumped
|
|
to stdout. Using the -f flag allows the table to be dumped one record at a time. If tables are very large, dumping to stdout can cause problems such as running out of memory.
|
|
|
|
=item B<-w> I<'attr==val'> B<-w> I<'attr=~val'> ...
|
|
|
|
Use one or multiple -w flags to specify the selection string that can be used to select particular rows of the table. See examples.
|
|
|
|
Operator descriptions:

|
|
|
|
B<tabdump> B<site>
|
|
|
|
=item *
|
|
|
|
To display the contents of the nodelist table where the groups attribute is compute :
|
|
|
|
B<tabdump> B<-w 'groups==compute'> B<nodelist>
|
|
|
|
=item *
|
|
|
|
To display the contents of the nodelist table where the groups attribute is comput% where % is a wildcard and can represent any string and the status attribute is booted :
|
|
|
|
B<tabdump> B<-w 'groups=~comput%'> B<-w 'status==booted'> B<nodelist>
|
|
|
|
=item *
|
|
|
|
To display the records of the auditlog on date 2011-04-18 11:30:00 :
|
|
|
|
B<tabdump> B<-w 'audittime==2011-04-18 11:30:00'> B<auditlog>
|
|
|
|
=item *
|
|
|
|
To display the records of the auditlog starting on 2011-04-18:

To see what tables exist in the xCAT database:
|
|
|
|
B<tabdump>
|
|
|
|
=item *
|
|
|
|
To back up all the xCAT database tables, instead of running B<tabdump> multiple times, you can use the B<dumpxCATdb> command as follows:
|
|
|
|
B<dumpxCATdb -p /tmp/xcatbak >
|
|
|
|
See the B<dumpxCATdb> man page for details.

|
|
|
|
B<tabdump> B<-d>
|
|
|
|
=item *
|
|
|
|
To display a description of each column in the nodehm table:
|
|
|
