ITM components communication

TEPS/TEP Client Communication Flow

  • HTTP connection is used by TEP browser to download JAR files and resources files that will be used by TEP client to communicate.

  • HTTP server is, by default, installed in TEPS.

  • IIOP CORBA layer is used by the client code to connect to TEP server.

  • TEPS communicates with TEMS using RPC method.

  • TEPS uses ODBC for Windows and DB2 client for Linux to communicate with the database.

  • URL for browser: http://<TEPS>:1920///CNP/client

TEP Browser Client Communication Flow

  • If IBM JRE 1.4.2 is not found, it would be downloaded and installed.

  • applet.html consists of OBJECT tag reference which instruct JRE to download JAR and reference files.

  • JAR and reference files are placed in the local cache and if the new version is available, it will be replaced automatically.

  • When java applet login is launched, no communication is made to TEP server yet.

  • Interoperable Object Reference (IOR) is downloaded through HTTP. Login method is invoked based on that reference.

  • The ras1header contains useful information about the environment where the server is running.

  • Use the ras1 header for a quick environmental triage

Using Tivoli Monitoring Service Index Console to set dynamic tracing

Using Tivoli Monitoring Service Index Console to set dynamic tracing

Advanced RAS1 Trace

  • To answer the question: Is the problem occurring in the TEPS?

  • ctdatabus unit is used to log all the detail request from TEP client

  • ctcmw and kv4 units are used to log node status, situation and EIB update events from TEMS.

  • ctsql is used to log raw SQL requests to TEMS, DB2 or ODBC and number of rows returned.

  • Use: KFW_DATABUS_INPUT_TRACE_IGNORE_HEARTBEAT=Y to suppress the heartbeat events in the log. Will greatly reduce the amount of logs.

  • Alternatively, KFW_DATABUS_INPUT_TRACE_FILTER=<service name> to log only the specified services.

SQL Input Trace

  • (UNIT:ctsql INPUT,ERROR)

  • Dumps raw SQL generated by the TEPS

  • Identifies data source where the SQL query will be sent

  • Logs number of rows returned to the requesting client

  • Counts the number of queries sent to each data source

SQL Input Trace

  • Examples:


    • HUB_TEMS(28): Rows returned: 1

  • Parm Markered Request to TEMS:


    • HUB_TEMS(316): Values: '1060719172155000' '1060720172155000' '000' '999' 'Y‘

    • HUB_TEMS(316): Rows returned: 12

TEPS Input Traces

  • Typically, databus and SQL input traces will be set together

  • CMW input traces will be set together, but not required

  • Databus trace is not useful when combined with CMW trace because no client request directly drives the event channels

  • If left running for long periods of time, or if many clients are connected and being actively used, databus and SQL input traces will generate large amounts of data
