resolve ram¶
Synopsis¶
codeql resolve ram [--ram=<MB>] <options>...
Description¶
[Deep plumbing] Prepare RAM options.
This deep plumbing command prepares appropriate command-line options to start a subcommand that will execute a QL query evaluator. It knows appropriate heuristics for deciding whether to keep some of the configured memory outside the Java heap.
In particular, this should be used to find appropriate -J-Xmx
and
--off-heap-ram
options before staring a query server based on a
desired total RAM amount.
Options¶
-
--format
=<fmt>
¶ Select output format. Choices include:
lines
(default): Print commmand-line arguments on one line each.json
: Print them as a JSON array.

-
-M

--ram
=<MB>

¶ [Advanced] Write detailed logs to one or more files in the given directory, with generated names that include timestamps and the name of the running subcommand.

--log-to-stderr
and redirect stderr as desired.)
