52 id: Normally the id corresponds to the Application-Id for which the dictionary provided is designed\n\
53 (in multistack applications, it shall be mandatory respect such association to know the stack used\n\
54 for processed messages).\n\
55 dictionary: Path to the dictionary file.\n\
56 validationMode: Sets the validation mode. Default is 'AfterDecoding'.\n\
57 validationDepth: Sets the validation depth. Default is 'FirstError'.\n\
58 fixMode: Sets the fix mode. Default is 'BeforeEncoding'.\n\
59 ignoreFlagsOnValidation: Ignore flags during message validation. Default is 'no'.\n\

67 originHost: Node identifier as diameter application host name.\n\
68 applicationId: The Application-Id provided must exists as a registered 'stack id'.\n\
69 originRealm: Origin-Realm (domain-name internally used by default).\n\
72 - Diameter clients:\n\
74 entity: Target diameter entity (comma-separated '<address>:<port>' format).\n\
75 For example: 10.20.30.40:3868,10.20.30.41:3868. If missing, no entity will be enabled.\n\
76 entityServerSessions: Diameter entity server sessions (0: diameter entity disabled). Default value of 1.\n\
77 cer: User defined CER path file to be encoded to establish diameter connections.\n\
78 If missing, will be harcoded.\n\
79 dwr: User defined DWR path file to be encoded for diameter protocol keep alive.\n\
80 If missing, will be harcoded.\n\
81 tcpConnectDelay: Milliseconds to wait TCP connect to any server. If missing, default value of 200 will\n\
83 ceaTimeout: Milliseconds to wait CEA from diameter server. If missing, default value of 'answersTimeout'\n\
85 watchdogPeriod: Milliseconds for watchdog timer (Tw) for diameter keep-alive procedure. If missing, default\n\
86 value of 30000 will be assigned.\n\
87 balance: Balance over entity servers instead of doing standard behaviour (first primary, secondary\n\
88 if fails, etc.). Default value 'no'.\n\
89 sessionBasedModelsClientSocketSelection: By default, round-robin will be applied for IEC model (SMS/MMS), and Session-Id Low Part\n\
90 will be analyzed for ECUR/SCUR model (data, voice and content). You could change ECUR/SCUR\n\
91 analysis behaviour providing 'SessionIdHighPart', 'SessionIdOptionalPart' (atoi applied;\n\
92 usually subscriber id data, i.e. MSISDN or IMSI) and 'RoundRobin' (also 'SessionIdLowPart').\n\
95 - Diameter servers:\n\
97 diameterServer: Diameter own server address in '<address>:<port>' format. For example: 10.20.30.40:3868.\n\
98 If missing, no local server will be enabled.\n\
99 diameterServerSessions: Diameter own server available connections (0: diameter server disabled). Default value of 1.\n\
100 Negative value implies no limit accepting incoming connections.\n\
101 cea: User defined CEA path file to be encoded to answer client CERs.\n\
102 If missing, will be harcoded.\n\
103 allowedInactivityTime: Milliseconds for the maximum allowed inactivity time on server sessions born over the\n\
104 local server before being reset. If missing, default value of 90000 will be assigned.\n\
109 answersTimeout: Milliseconds to wait pending application answers from diameter peers. If missing,\n\
110 default value of 10000 will be assigned.\n\
111 retries: Expired responses will cause a number of request retransmissions. Disabled by default (0 retries).\n\
112 log: Process log file (operations result, traffic log, etc.). By default '<originHost>.launcher.log'.\n\
113 Empty string or \"null\" name, to disable. Warning: there is no rotation for log files\n\
114 (use logrotate or whatever you consider).\n\
115 splitLog: Splits log file (appends to log filename, extensions with the type of event: see help on\n\
116 startup information-level traces). No log files for code/decode and load operations are created.\n\
117 Default value 'no'.\n\
118 detailedLog: Insert detailed information at log files (timestamps, communication resources, etc.). Useful\n\
119 to analyze the messages flow along the sockets (specially on 'balance' mode). Default 'no'.\n\
120 dumpLog: Write to disk every incoming/outcoming message named as:\n\
121 '<unix ms timestamp>.<originHost>.<hop by hop>.<end to end>.<message code>.<request|answer>.<type of event>.xml'\n\
122 Default value 'no'.\n\
123 burstLog: Burst operations log file. By default '<originHost>.launcher.burst'. Empty string or \"null\" name, to disable.\n\
124 Warning: there is no rotation for log files (use logrotate or whatever). Output: dot (.) for each\n\
125 burst message sent/pushed, cross (x) for popped ones, and order number when multiple of 1% of burst\n\
126 list size, plus OTA requests when changed.\n\
