Function START_SESSION

RDB$PROFILER.START_SESSION starts a new profiler session, makes it the current session (of the given ATTACHMENT_ID) and returns its identifier.

If FLUSH_INTERVAL is different from NULL, auto-flush is set up in the same way as manually calling RDB$PROFILER.SET_FLUSH_INTERVAL.

If PLUGIN_NAME is NULL (the default), it uses the database configuration DefaultProfilerPlugin.

PLUGIN_OPTIONS are plugin specific options and currently should be NULL for the Default_Profiler plugin.

Input parameters

  • DESCRIPTION type VARCHAR(255) CHARACTER SET UTF8 default NULL

  • FLUSH_INTERVAL type INTEGER default NULL

  • ATTACHMENT_ID type BIGINT NOT NULL default CURRENT_CONNECTION

  • PLUGIN_NAME type VARCHAR(255) CHARACTER SET UTF8 default NULL

  • PLUGIN_OPTIONS type VARCHAR(255) CHARACTER SET UTF8 default NULL

Return type: BIGINT NOT NULL.

Procedure CANCEL_SESSION

RDB$PROFILER.CANCEL_SESSION cancels the current profiler session (of the given ATTACHMENT_ID).

All session data present in the profiler plugin is discarded and will not be flushed.

Data already flushed is not deleted automatically.

Input parameter

  • ATTACHMENT_ID type BIGINT NOT NULL default CURRENT_CONNECTION
