Linux-UNIX: Discovery parameters

The discovery parameters define the behavior of the auto-discovery feature, for discovering database instances and sending the results to the current active S-TAP.

Attention: These are advanced parameters and should be modified only by IBM Technical Support.
GIM guard_tap.ini Default value Description
STAP_DISCOVERY_INTERVAL discovery_interval 24 The time interval at which auto-discovery runs. Valid values:
  • 0: disabled
  • < 0: interval in minutes
  • > 0: interval in hours
Default = 24 (hours)
STAP_DISCOVERY_DBS discovery_dbs oracle:db2:informix:mysql:postgres:sybase:hadoop:teradata:netezza:memsql Colon (':') separated list of database types to attempt to discover.

Can be set when pushing to a group of DB servers via GIM.
STAP_DISCOVERY_DEBUG discovery_debug 0 Output debug information from discovery. The log is guard_discovery.stderr.log located in the directory specified by the parameter tap_log_dir (by default: /tmp/guard_stap).
  • 0: disable (errors only)
  • 1: errors and debug statements

Can be set when pushing to a group of DB servers via GIM.
STAP_DISCOVERY_ORA_ALT_LOCATIONS discovery_ora_alt_locations Alternate locations to look for listener.ora files.

Can be set when pushing to a group of DB servers via GIM.
STAP_DISCOVERY_ORA_USE_PORT_RANGES discovery_ora_use_port_ranges 0 Enable S-TAP discovery of Oracle databases to combine discovered instances based on port ranges. This setting works with a single unix_domain_socket_marker. Multiple unix_domain_socket_marker configurations require separate instances.
Valid values:
  • 0: disabled
  • 1: enabled
STAP_DISCOVERY_PORT discovery_port 8443 S-TAP Discovery uses this port to connect to the Guardium® system.
