Virtuoso Server configuration is determined by a virtuoso.ini file when
server starts. This file includes both system-specific information from
your install (location of server files, addons, etc) and user-configurable
parameters. This helper function provides a way to create and modify an
appropriate virtuoso.ini file.
Usage
vos_configure(
dirs_allowed = getwd(),
gigs_ram = 2,
template = find_virtuoso_ini(),
db_dir = vos_db()
)Arguments
- dirs_allowed
Paths (relative or absolute) to directories from which Virtuoso should have read and write access (e.g. for bulk uploading). Should be specified as a single comma-separated string.
- gigs_ram
Indicate approximately the maximum GB of memory Virtuoso can have access to. (Used to set NumberOfBuffers & MaxDirtyBuffers in config.)
- template
Location of an existing virtuoso.ini file which will be used as a template. By default,
vos_configure()will attempt to locate the appropriate template for your system.- db_dir
location where
virtuoso.inifile should be written. Other Virtuoso database log files will also be written here.
Value
Writes the requested virtuoso.ini file to the db_dir specified
and returns the path to this file.
Examples
# \donttest{
# can take > 5s to test
## configure with typical defaults:
vos_configure()
#> Warning: Exiting, virtuoso template not found... is virtuoso installed?
## Increase or decrease RAM available to virtuoso:
vos_configure(gigs_ram = 1)
#> Warning: Exiting, virtuoso template not found... is virtuoso installed?
# }
