no-remote-trace—Disable remote tracing.

no-world-readable—(Optional) Disable unrestricted file access.

size maximum-file-size—(Optional) Maximum size of each trace file. By default, the number entered is treated as bytes. Alternatively, you can include a suffix to the number to indicate kilobytes (KB), megabytes (MB), or gigabytes (GB). If you specify a maximum file size, you also must specify a maximum number of trace files with the files option.

  • Syntax: sizek to specify KB, sizem to specify MB, or sizeg to specify GB

  • Range: 10240 through 1073741824
