 File System Manager Handling access to
Siebel File System
Architecture Overview – Server Component Types
Different types of component run in different ways:
 Background
Background mode components execute tasks to perform background
operations for the Siebel Server. After a background mode component task
starts, it runs until you explicitly stop the task, or until the Siebel Server itself
is shut down.
 Interactive
Interactive mode components start tasks automatically in response to client
requests. Interactive mode component tasks execute for as long as the client
maintains the session, and end when the client disconnects.
 Batch
Batch mode components execute tasks in response to requests. Batch mode
component tasks execute until they finish processing.
Internal batch tasks are initiated by other Siebel Server tasks
External batch tasks are initiated by Server Manager
Architecture Overview – Component Execution Platforms
Different types of component execute in different platforms:
 Single Threaded
Single threaded components have one execution stream per process. So
each operating system process supports a single Siebel Task.
i.e. EIM
 Multi-threaded
Multi-threaded components have multiple execution streams within a single
process.. So each operating system process can support multiple Siebel
Tasks.
i.e. Object Managers

How Components Scale in a Siebel 7 Enterprise
 Scaling within a server
 Multi-threaded components
 Single-threaded components
 Scaling across servers
 Load balancing
 Resonate central dispatch
 Load sharing
 Server Request Broker
 Server Request Processor
Scaling Within a Siebel Server
 Single Threaded Components
 Create multiple processes (tasks)
 Some components are limited
i.e.
 Transaction Processor – max 1 per server
 Workflow Monitor Agent – max 1 per policy group per Enterprise
 Can be started manually, through Server Request Broker, or
automatically (‘Default Tasks’ parameter)
 Multi-Threaded Components
 Create multiple threads &/or processes (tasks)
 Control distribution through component parameters
Multi-Threaded Components
 Can have multiple processes as well as multiple threads
 Important to control ratio of threads to processes
 Can have major impact on performance
 Determined primarily by rate of switches between threads
 100:1 good starting point for Client Object Managers
 Assumes 30sec think time
 For 15 sec think time use 50:1
 Can set additional processes to spawn on demand
 Will always start minimum number specified
 Will start additional processes as needed to maintain process:thread
ratio
 Limit on maximum number of processes
Memory Scalability
 Multi-Process, Multi-Threaded model
 All threads in a process share the same memory space
 Each Process has a separate memory space
 No single process needs a large memory space
 Operating system manages memory allocation
 If a single process needs more than 1GB there’s normally something
wrong
 No need for large process memory model (‘/3GB’ switch)
 Can use Microsoft PAE for access to large memory capacities
 Operating system can allocate memory to each process
Multi-Threaded Component Parameters
 Typically set per component
 Maximum number of tasks (MaxTasks)
 Maximum number of Tasks per component per server
 One thread per task
 Some additional background “system” threads - not counted by MaxTasks
 Maximum number of Multi-Threaded servers (MaxMTServers)
 An MTServer is a multi-threaded component process
 This defines the maximum number of MTServers per component per server
 Minimum number of Multi-Threaded servers (MinMTServers)
 This defines the minimum number of MTServers per component per server
 Sets the number of MTServers started on server startup
Configuring the Object Managers
 Set MaxTasks = peak (concurrent users + anonymous users)
 Anonymous users are used for login screens before user authenticates
 Typically set to 10%-15% of concurrent user count
 Set MaxMTServers = MaxTasks / 100
 An MTServer is equivalent to single instance of Object Manager
 100 : 1 ratio is assuming “average” 30 second think time between user
operations
 If average user think time is 15 seconds then ratio is 50 : 1 ( 50% of 100:1)
 If average user think time is 60 seconds then ratio is 200 : 1 (200% of 100:1)
 Set MinMTServers = MaxMTServers
 Setting MinMT Servers < MaxMTServers may cause delay of service for
“new” users as MTServer gets initialized.

Scaling Across Siebel Servers
Depends on how component task initiated
 Component Group Assignment
 Which servers a component is available on
 Object Managers
 Load balanced (Resonate Central Dispatch)
 Not valid for eConfigurator Object Manager
 Siebel Remote
 Manual allocation of mobile client to Siebel Server
 Server Requests
 Server Request Broker &/or Server Request Processor
 Manual Requests (start task)
 Manually specified server
 Special cases
 CTI
 eConfigurator

Server Request Broker & Server Request Processor
 Server Request Broker (SRBroker)
 Used to start synchronous Siebel Server tasks
 Server Request Broker & Server Manager are the only components
which directly start tasks.
 New in Siebel 7
 Replaces Server Request Manager (SRMSynch) in Siebel 2000
 Background component
 Multi-threaded component
 Need to set MaxTasks accordingly
 Server Request Processor (SRProc)




Used to start asynchronous Siebel Server tasks
Manages queued requests
Calls SRBroker to manage task execution
Background component
Server Request Broker
 Accepts requests from other Components
 Will try to service request locally
 If component is available on same Siebel Server then this is always
used
 If not available locally then will use other Siebel Servers
 Maintains internal table of components available on each Siebel
Server
 Will route requests round Siebel Servers in turn (round-robin)
 Multi-threaded component
 May need to increase MaxTasks
 Should always be running on all servers

Connection Pooling
Siebel 7 can pool sessions at two levels:
 Web server to Siebel Enterprise




SISNAPI Connection Pooling
Multiple SISNAPI (Siebel) sessions through one TCP session
Reduces operating system overhead and network traffic
Enabled by default
Set to 20
 Controlled by component parameter:
‘Number of Sessions per SISNAPI Connection’
 Siebel Object Manager to Database





Database connection pooling
SQL traffic for multiple Siebel users through one database session
Reduces session overheads on database server
Disabled by default
Suitable for larger deployments (over 500 concurrent users)
Database Connection Pooling
 Connections use native database protocols
 Some components directly access native protocol
 Object Managers
 Siebel 7 supports its own database connection pooling
 Used for connections from Object Managers
 Two types of connection
 Shared – for general transactions
 Specialized – for long running
 Not always appropriate
 Should carefully evaluate tradeoffs
 Benefits of less database sessions to maintain
 Risk of database session contention
Database Connection Pooling
 Database session uses login for first user to establish
session
 Database connection pooling controls
 Defined as component parameters
 Set to ‘-1’ to disable (default)
 Specialized (Dedicated) Database sessions
 All valid per component process (MT Server) per Siebel Server
 MaxTrxDbConns
- Maximum number of specialized DB sessions
 MinTrxDbConns
- Minimum number of specialized DB sessions
to be kept in pool
 Shared Database sessions
 Valid per component per Siebel Server
 MaxSharedDbConns- Maximum number of shared DB sessions
 MinSharedDbConns - Minimum number of shared DB sessions
to be kept in pool

Architecture Overview

Performance Optimization
Performance Management
General Siebel Server Optimisation
 Disable unused components and component groups
These just use up system resources
 Consider using common log file for multi-threaded
components that generate too many log files
 Consider using multiple instances/server tasks for certain
activities
e.g. Parallel EIM, multiple Workflow Policy Groups, etc.
 Monitor resource utilization by processes and threads
Object Manager Optimization
 Enabling View Caching for High Interactive mode






Set in user preferences
Faster client response times, by as much as 1 second
Better network behavior
Expensive, 3MB per view cached
Most users use < 10 views / pages
Uses LRU mechanism to flush out cache
 If not using eAdvisor or browser based eConfigurator
 On cfg file set “EnableCDA = FALSE”
 Set “Timed Statistics” Off
 Set all Log Levels to 1
EAI Optimization
 Minimize fields in Integration Components
 Keep XML records small
 XML is very verbose and needs to be parsed
 Lump several records into one transaction
 will achieve higher throughput
 If possible keep records to 15 fields
 More will reduce throughput
 Keep in mind that an XML field translates to BC field
 Integration Object initialize Business Objects and Business
Components
 The more fields per record the slower it will process
EAI Optimization
 Reduce SessPerSisnConn for EAI Adapters
 Do this only if you are going to “bombard” adapter, i.e. little or no
think times
 For very high throughput systems where you are
dedicating EAI machines
 Consider letting the SRB forward BIM requests to dedicated
machines
 BIM processing can become bottleneck if BIM processing is complex
 May be necessary to have a higher EAI Adapter:BIM machine ratio
(i.e. 1:x)
 Use ‘Session-Mode’ for high volume inbound HTTP
 Greatly increased throughput
 No overhead for authentication & session startup for each message
Workflow Process Optimisation
 Use Run-Time Events for process automation
 Minimize use of Workflow Policies since workflow policy work at the
database layer and do not take advantage of the level of abstraction
provided with the Object Manager
 Performance gain since the decision event takes place on the
business object layer and so no trigger is created on the table
 No need for scripting
 Workflow Process Distribution
 Workflow Policies can’t be directly load balanced
 Asynchronous Workflow Processes are distributed by SRProcessor
 Synchronous Workflow Process requests are distributed by
SRBroker
Application Performance - Configuration
 Keep scripting small and tight
 Avoid the use of script wherever possible
 Remember it is still interpreted code and will execute as such
 Ensure all objects are destroyed after use – avoid memory leaks
 MVG Applets
 Keep to a minimum as they increase SQL complexity
 Use primary joins as much as possible; reduces number of SQL
statements
 Use SmartScript only where really required
 E.g. Novice Call Center users
 Avoid putting external news pages on login page
 3rd party web sites can be slow
Application Performance - Configuration
 Activate only fields that are absolutely necessary
 Become active when displayed; “Force Active” in BC configuration
 General rule, the more fields on a page the slower the page
 Recently saw customer with 750 fields and 80 tables for one applet
 Include only manageable set of fields on list applets
 Many customers use several dozen fields; not usable and slow
performance
 Pages with more than three applets will perform slower for
HI applications
 Reason for this is not really the number of applets, rather the number
of fields
 PickLists set Long List to TRUE if returning large data sets
 Tree Applets can be slow
 They generate Bill of Materials type queries
Network Performance – Siebel Configuration
 Browser Validation
 Reduces the need for server communications to validate data entry
 Implement through browser script
 Immediate Posting of Changes
 Where the ‘Immediate Post Changes’ flag is set against a field data
will be transferred whenever a field is changed
 Incurs additional round trip with approx 2KB data
 Keep to no more than two Applets per View
 Minimize Popups
 Limit columns in List Applets
Network Performance – Siebel Settings
 View Caching
 View definitions cached in browser memory
 Requires approx 3MB memory per view
 Typically around 10 cached views is enough
 Uses LRU algorithm to maintain cache contents
 Personalization and Applet Toggles won’t use view caching
 Enabled through Object Manager configuration (.cfg) file setting
[SWE]
EnableViewCache=TRUE
 Controlled through:
 User Preferences > Behaviour > View Cache Size
 Default: 10
Network Performance – Siebel Settings
 Compression (Dynamic Content)
 Performed by SWSE
 Do not use web server dynamic compression (application files)
 Enabled through SWSE configuration file (‘eapps.cfg’)
[Defaults]
DoCompression = TRUE
 Compression (Static Content)
 Performed by web server (IIS only)
Network Performance – Web Server / Browser Settings
 Browser Settings
 Don’t clear cache except when necessary
 Ensure ‘Empty Temporary Internet Files Folder when browser is
closed’ option is not enabled.
Network Performance – Web Server
 Web Server Settings
 Use HTTP keep-alive
 Reduces the need to negotiate TCP sessions for each HTTP message
Network Performance – Web Server
 Web Server Settings
 Set Content Expiration
 2 days is typical setting
 Set through Internet Information Services Administration
 HTTP Headers > Content Expiration

Performance – Problem Diagnosis
 What is the problem?
 Slow response times reported by User(s)?
 Resource utilisation problem reported by Administrator?
 Where is the problem?
 Who is experiencing the problem? One user, a subset of users, all
users?
 Network problem?
 Database problem?
 Siebel Server problem?
 Web Server problem?
 How do we resolve the problem?
Performance – Problem Diagnosis continued
 Problem Identification
 User reports slow response times
 Identify precise actions carried out by user at the precise time of the
problem – set up a problem reporting process, with required
information to be supplied by user
 Subset of Users report slow response times
 Are users on the same LAN segment? Are other users experiencing
problems?
 Are users all performing similar tasks?
 All users report slow response times
 Is it specific transactions (views) that are slow?
 Do all transactions run slowly?
 System Administrators should check system resource utilisation
 System Administrator(s) report resource utilisation problems
 Are users experiencing problems as a result?
 Which area of the system is experiencing problems
 Ask questions of the relevant people – need more
information than ‘The system seems to be slow’
