Each entry in the oraNavigatorTable represents a Navigator on the node. Each entry is indexed by applIndex; thus, there is a one-to-one (or interchange) relationship between an Oracle MultiProtocol Interchange and its Navigator. (For details about applIndex, see Appendix F, "Interpreting Implemented Variables of the Network Services MIB.") The current value of each oraNavigatorTable variable is retrieved from a file the Navigator creates.
Table C - 2 lists the variables included in the oraNavigatorTable.

A description of each of these variables follows.
| Syntax | DisplayString |
| Max-Access | read-only |
| Explanation | Indicates the elapsed time (in seconds) since a Navigator was last started, as calculated from the current date and time at that moment. This value is reset to 0 when the Navigator is restarted. |
| Typical Range | 1 - 80 characters |
| Significance | less important |
| Related Variables | oraNavigatorStartTime |
| Suggested Presentation | clock or simple string |
| Syntax | INTEGER (1) on, or (2) off |
| Max-Access | read-write |
| Explanation | Indicates whether a Navigator should log requests from the Connection Manager and the Pumps. |
| Typical Range | enumerated 1 or 2 |
| Significance | important |
| Related Variables | oraNavigatorLogFile, oraNavigatorLoggingLevel |
| Suggested Presentation | ON/OFF switch |
| Syntax | INTEGER (1) all, or (2) errors. |
| Max-Access | read-write |
| Explanation | Indicates whether a Navigator should log all requests from Pumps and the Connection Manager, or errors only. |
| Typical Range | enumerated 1 or 2 |
| Significance | important |
| Related Variables | oraNavigatorLogFile, oraNavigatorLogging, |
| Suggested Presentation | icon or simple integer |
| Syntax | DisplayString |
| Max-Access | read-only |
| Explanation | Indicates the name of the log file the Navigator created. The default log file name is specific to the operating system; for UNIX, it is /$ORACLE_HOME/network/log/navgatr.log. |
| Typical Range | 1 - 255 characters |
| Significance | important |
| Related Variables | oraNavigatorLogging, oraNavigatorLoggingLevel |
| Suggested Presentation | simple string |
| Syntax | INTEGER (1 - 17) |
| Max-Access | read-write |
| Explanation | Indicates the level at which a Navigator should be traced. A value of 4 means that tracing at the USER level is turned on; and 6 means that tracing at the ADMIN level is turned on. A value of 17 means that tracing is turned off. |
| Typical Range | enumerated 1 - 17 |
| Significance | important |
| Related Variables | oraNavigatorTraceFile |
| Suggested Presentation | as an icon, or as a simple string of characters, OFF, USER or ADMIN |
| Syntax | DisplayString |
| Max-Access | read-only |
| Explanation | Indicates the name of the trace file the Navigator created. The default trace file name is specific to the operating system; on a UNIX platform, it is /$ORACLE_HOME/network/trace/nav_pid.trc, where pid is the process ID of the Navigator |
| Typical Range | 1 - 255 characters |
| Significance | important |
| Related Variables | oraNavigatorTraceLevel |
| Suggested Presentation | simple string |
| Syntax | INTEGER (1) yes, or (2) no. |
| Max-Access | read-write |
| Explanation | Indicates whether a Navigator can be stopped using the Oracle MultiProtocol Interchange Control Utility program (INTCTL). A value of 1 means that the Navigator is stoppable; a value of 2 means that it is nonstoppable. |
| Typical Range | 1 or 2 |

| Related Variables | none |
| Suggested Presentation | simple string |
| Syntax | Counter32 |
