Installation guide

generic:
lockmode = 4
dump-sp-threshold = 6000
Suppose that you create a file named merge_attrs for updating this entry,
which contains the following information:
generic:
lockmode = 0
lockmaxcycles = 4294967295
To merge the information in the merge_attrs file into the
/etc/sysconfigtab database, issue the following command:
# /sbin/sysconfigdb -m -f merge_attrs generic
After the command finishes, the entry for the generic subsystem in the
database appears as follows:
generic:
lockmode = 0
lockmaxcycles = 4294967295
dump-sp-threshold = 6000
You can merge definitions for more than one subsystem into the
/etc/sysconfigtab database with a single sysconfigdb -m command.
For example, the merge_attrs file could contain new definitions for
attributes in the lsm and generic subsystems. If you include more than
one subsystem name in the merge_attrs file, you omit the subsystem
name from the command line, as shown:
# /sbin/sysconfigdb -m -f merge_attrs
5.3.8.4 Updating Attributes in the Database
To update the entire definition of a subsystem that is already in the
/etc/sysconfigtab database, enter the /sbin/sysconfigdb −u
command.
For example, suppose the generic subsystem is defined as follows in the
/etc/sysconfigtab file:
generic:
lockmode = 4
dump-sp-threshold = 6000
Suppose that you create a file named update_attrs for updating this
entry, which contains the following information:
generic:
lockmode = 0
