SPD Server uses four types of component files to store a server table. In addition,
it supports
partitioning of the component files. By default, all the files are stored in PATHNAME=,
which is considered the
primary path. You can specify dedicated paths for component files by specifying the following
options in the domain specification:
DATAPATH=
specifies a list of paths that contain data files that are associated with the domain.
INDEXPATH=
specifies a list of paths that contain index files that are associated with the domain.
METAPATH=
specifies a list of
paths that are allocated to contain overflow metadata if the designated
metadata space that is allocated in the PATHNAME= option statement
becomes full.
WORKPATH=
specifies a list of paths that contain temporary work tables and intermediate files
that are associated with the domain.
Note: Use this option with caution.
When set, it overrides the WORKPATH= setting in the spdsserv.parm
parameter file and does not apply only to the domain.
ROPTIONS=
contains the optional path locations within the libnames.parm parameter file.
Use the following syntax to specify optional paths in the libnames.parm parameter
file:
libname=domain-name
pathname=primary-path
roptions="datapath=('data-path_1' 'data-path_2' ... 'data-path_n')
indexpath=('index-path_1' 'index-path_2' ... 'data-path_n')
workpath=('work-path_1' 'work-path_2' ... 'work-path_n')
metapath=('meta-path_1' 'meta-path_2' ... 'meta-path_n')";
