90E_PSL_BUSY_CHANNEL 

No two reader processes (such as the read() orreadln() functions) can be blocked on the same channel.

The second reader process that attempts to block the shared channel will fail; in addition, a write() function on a read-blocked channel will also fail.

This helps enforce serialization for shared channels. 

91E_PSL_UNBLOCKED_BY_CLOSE shared channel failure; a close() function has been executed against a channel that also has a blocked reader process 
92E_PSL_FULL_DISCOVERY_BAD_APP the full_discovery() function is being run in a context other than an application

or

the PSL chart() function used with CHART_PRINT or CHART_DESTROY and ID has been omitted 

94E_PSL_SOCKET_BUSY 

Thesnmp() function attempted to use a socket that was already in use

This error may also result from using the snmp_trap_listen() and snmp_open() functions. 

95E_PSL_TIMEOUT An SNMP request timed out while waiting for response from an SNMP session 
96E_PSL_BAD_FUNCTION_PARAMETER 

There was an error in the way the function was called; one of the arguments supplied (or not supplied) for the function call was bad.

This error may occur for a variety of reasons. The following are a few of the problems that may generate this error:

  • bad object id
  • invalid object type
  • no object type
  • no object value
  • required arguments missing
  • the non-numeric value supplied on a function that requires a number
  •  host name supplied but the host does not exist
  • option supplied to a function that supports a limited number of options and the one supplied is not on the list
97E_PSL_SNMP_NOT_SUPPORTED a PSL SNMP function was called, but this agent is configured with SNMP support turned off 
98E_PSL_SNMP_ALREADY_LISTENING the socket is already active to accumulate SNMP traps 
99E_PSL_SNMP_NOT_LISTENING the socket is not open to accumulate SNMP traps 
100E_PSL_SNMP_ERROR function terminated due to an error in the SNMP session 
  The function's return value contains the error information from the SNMP session. 
101E_PSL_BAD_OBJ invalid object specified 
102E_PSL_NOT_PARAM object type is not a parameter 
103E_PSL_NO_RTCELL object does not exist or is not a parameter 
104E_PSL_NOT_SUPPORTED returned when the PSL internal() function is run in the standalone interpreter 
105E_PSL_ANN_NO_HISTORY_RETENTION 

the parameter is valid but the timestamp was omitted

This indicates that no annotations exist for any value of the parameter in the PATROL Agent history database or the timestamp is specified and no annotation exists for the value of the parameter at that timestamp. 

106E_PSL_REMOTE_QUERY_COMM_ERR the remote_event_query() function returned an error from the remote agent 
107E_PSL_REMOTE_QUERY_CREATION could not construct the remote event query

109E_PSL_REMOTE_OPEN_ERR unable to open remote agent connection 
110E_PSL_FAULT 

the va_start()or va_arg() function was used incorrectly

The va_start() and va_arg() functions can only be used in the context of a user-defined function definition. 

111E_PSL_BAD_DATE_STRING the convert_date()or convert_date_locale() function could not parse the date and time string 
112E_PSL_BAD_TIMEZONE the convert_date()or convert_date_locale() function did not recognize the specified timezone 
113E_PSL_CANNOT_DETERMINE_ TIMEZONE The convert_date() function uses GMT for the timezone because no timezone was supplied and the timezone used by the computer system could not be determined. 
114E_PSL_LOCK_DESTROYED The destroy_lock() function terminated a lock. 
115E_PSL_ANN_TOO_EARLY 

The annotate() function was called before any data point was generated.

This occurs when the annotate() function is called before a set() function can set the parameter value. 

116E_PSL_ANN_SAVE_FAILED 

could not save annotation information

This occurs when an attempt to save the annotation data fails. The error may be caused by permission restrictions on the history database or as the result of an internal PATROL error.
