Administration Commands

query_trace_file

CS

File contains tracing on data transferred across the SNAplus2 domain between the specified computer and other nodes. This trace type is activated by the set_cs_trace command.

BCK_CS

File contains tracing on data transferred across the SNAplus2 domain between a current-level server and back-level computers. This trace type is activated by the set_bck_cs_trace command.

TN_SERVER

File contains tracing on the SNAplus2 TN server component.

IPS

File contains tracing on kernel components for the specified node. This type of trace is activated by the set_trace_type or add_dlc_trace command.

If the command executes successfully, SNAplus2 returns the following parameters:

trace_file_type

The type of trace file for which information is required (as supplied on the query_trace_file command).

dual_files

Specifies whether tracing uses one file or to two files. Possible values are:

YES

Tracing uses two files. When the first file reaches the size specified by trace_file_size, the second file is cleared, and tracing continues to the second file. When this second file then reaches the size specified by trace_file_size, the first file is cleared, and tracing continues to the first file. This ensures that tracing can continue for long periods without using excessive disk space; the maximum space required is approximately twice the value of trace_file_size.

NO

Tracing uses one file.

trace_file_size

The maximum size of the trace file. If dual_files is set to YES, tracing switches between the two files when the current file reaches this size. If dual_files is set to NO, this parameter is ignored; the file size is not limited.

file_name

Name of the trace file, or name of the first trace file if dual_files is set to YES.

If no path is included, the file is stored in the default directory for diagnostics files, /var/opt/sna. If a path is included, this path is either a detailed path (starting with a [/] character) or the path relative to the default directory.

file_name_2

Name of the second trace file; this parameter is used only if dual_files is set to YES.
