1 WebSphere Application Server - Best Practices: Performance Tuning presented by: Michael S. Pallos, MBA Senior Solution Architect IBM Certified Systems Expert: WebSphere MQ 5.2 e-business Solution Designer/Technologist Candle Corporation
2 Agenda Presentation Logistics WAS Architecture Best Practices Performance Analysis Tuning techniques Hardware IBM HTTP Server Application Server Database Server
3 Architecture Infrastructure and Web Applications
4 General Architecture WebSphere Application Server is based on the IBM Enterprise Server for Java Specification Three logical tiers within the application server: Core HTTP engine Web Container (Servlet engine) EJB Container (Enterprise Java Bean engine) Communication between tiers implemented as plug-ins This makes performance tuning a combinatorial problem Configuration changes propagate and side effects cascade WAS 5.0 is J2EE 1.3 WAS 4.x is J2EE 1.2 no JMS or JCA
5 General Architecture Core HTTP engine / Web Server Connection manager Native Web server plug-in Web Container / (Servlet engine) EJB Container Interface EJB Container JTS JBDC JNDI IIOP Tools to create, test, deploy, and manage Web applications
6 Core HTTP Engine Handles requests for static resources HTML CGI programs Plug-ins applications Graphics Sends servlet requests to the Web Container Logs into the servlet engine Core HTTP engine
7 Core HTTP Engine Core HTTP engine Core HTTP engine Core HTTP engine First line of scalability by using an HTTP sprayer (IND) with multiple servers running in a cluster Can use the roundrobin method or intelligent routing based on real-time workload metrics
8 Core HTTP Engine Interactive Network Dispatcher HTTP Engine Instance 1 HTTP Engine Instance 2 HTTP Engine Instance n Shared or Replicated Resources, Shared Database, Shared Files, Shared Sessions
9 Core HTTP Engine Measuring performance: Response time Turnaround time for handling a single HTTP request Throughput Total number of simple HTTP requests that can be handled by the engine in one second Core HTTP engine
10 Web Container Web Container Run-time environment plugs into supported Web servers via ISAPI and NSAPI Passes servlet requests to servlet manager Servlet manager processes request and sends data back to client
11 Web Container Contains most tuning points Very sensitive to topology choices Can be cloned Sometimes it helps boost performance depending on the platform Web Container Connection Web Container manager Servlet engine
12 Servlet Engine Generic Apache IIS Netscape Go Domino Various WebSphere App. Server Plug-Ins Servlet Service Manager SSI JNDI/LDAP IIOP Session State User Profile Enhanced Servlet API Java SSL Servlets EJB Container With JTS GWAPI Plug-Ins JSPs Connector Beans and Connection Manager Config Svc JSP Processor <HTML> <HTML> <HTML> <JAVA> <JAVA> <JAVA> If( ) If( ) If( ) <Servlet> <Servlet> <Servlet> Configuration requests from common Web-based UI Configuration Repository (property files or LDAP) Isolated in its own Process(es) Java connectors to various back ends, CICS, etc
13 EJB Container Handles lifecycle and persistence for EJBs Performance can be affected by the fact that it accepts IIOP connections and it has to ensure transactional integrity JTS JBDC JNDI IIOP
14 EJB Container Inherently slow Name resolution is an expensive task EJBs are heavy JTS JBDC JNDI IIOP Database connections are also expensive Performance tuning is critical

23 Appendix Performance Analysis & Tuning Techniques Calculations
24 Hardware You must run on the right hardware Hardware alone cannot solve performance problems Hardware should get out of the way and let the application run without interference This is the intended role
25 Hardware No CPU under 300 MHz should be considered The more the merrier Your can never have enough memory Consider at least 512 MB per CPU Maximize Tx and Rx queues on your network adapter to handle traffic
26 AIX There are a few things you need to modify on AIX if you want to run WebSphere Some setting must be modified at installation time Some other settings needs to be changed as a result of the application behavior on WebSphere
27 TCP/IP Settings on AIX thewall Default is 1 GB or ½ of real memory (smallest one) Increase in 4KN increments sb_max Increase size in increments of 4096 bytes somaxconn Specifies maximum listen backlog Default is 1024 Bytes Increase in 1KB increments
28 TCP/IP Settings on AIX Tcp_sendspace Sets the value fort the tcp socket send buffer size Increase in multiples of 4096 Bytes Changes take effect immediately Tcp_recvspace Sets the value for the tcp socket receive buffer size Increase in multiples of 4096 Bytes Changes take effect immediately It s never higher than the major network adapter transmit queue limit
29 TCP/IP Settings on AIX Udp_sendspace Increase in multiples of 4KB Changes take effect immediately Udp_recvspace Set starting value at 10*udp_sendspace Increase size in 4KB increments Changes take effect immediately
30 TCP/IP Settings on AIX Rfc1323 Set to 1 This means tcp_sendspace and tcp_recvspace can grow about 64 KB You ll need to set rfc1323 = 1 on both sides if you want good performance If rfx1323 <> 1 on both sides then tcp_sendspace and tcp_recvspace will be limited to 65536
31 TCP/IP Settings on AIX Tcp_timewait Default is 1 second Increase in intervals of 15 seconds Tcp_mssdflt Sets the maximum packet size when talking to remote networks IN this case size pertains only to data in the packet (no overhead) Set to MTU - 52 to ensure transmission of full packets only Changes take effect immediately
32 TCP/IP Settings on AIX Ncb_max_cache Defines the maximum size of the Network Buffer Cache Default is 128 KB Objects larger than 128 KB will not be cached Adjust depending on network speed and average object size for the application Consider serialized copies of persistent objects
33 TCP/IP on AIX MTU Defines the packet size Default value depends on the adapter installed on the machine Range goes for 512 Bytes to Bytes Use isattr command to see current settings Use chdev to change the value All MTUs must be equal across the network to avoid bottlenecks Changes are persistent
34 File Descriptions on AIX Ulimit Default is 2000 Usually good enough for small machines If Memory allocation error occurs, set it to - unlimited This was observed on a 24-way RS/6000 S80 running 4 clones Usually better for large SMP machines with clones
35 Solaris Performance tuning on Solaris is a little similar to AIX There are a few differences in the way AIX and Solaris manage TCP/IP communications The following tuning parameters apply to Solaris 2.6 and 2.7
36 TCP/IP Settings on Solaris Tcp_close_wait_interval The default value is ms but it s usually too high Set it to ms as a starting point and measure connection delays Increase or decrease according the patter of behavior exhibited by the application
37 TCP/IP Settings on Solaris Some customers report performance gains by tuning other settings within the TCP/IP stack: Tcp_conn_req_max_q Tcp_comm_hash_size Tcp_xmit_hiwat
38 File Descriptors on Solaris Ulimit Set this parameter to be at least 1024 Use ulimit -n 1024 to set the parameter Use ulimit -a to display current values and system limitations If you see a Too many files open error on WebSphere s stderror.log file you will need to increase the value above 1024 Increase or decrease according to the pattern of behavior exhibited by your application
39 Windows NT Windows NT has fewer tuning points than other supported operating systems This is not necessarily a good thing
40 OS Level and Virtual Memory Operating system level Version 4, Service Pack 5 or later Version 5 (windows 2000), Service Pack 2 Virtual memory Set initial size to 300 MB, maximum size to 400 MB Increase or decrease according to the patter of behavior exhibited by the application Do not let Windows manage it for you
41 IBM HTTP Server
42 The Web Server First queue in the WebSphere Queuing Network Needs to be tuned in combination with the servlet engine queue in most cases Additional considerations must be taken if using SSL
43 IBM HTTP Server The IBM HTTP Server for AIX holds the world record for the performance benchmark result by SPECweb96 The record was set on January 2000 on a RS/6000 S80
44 Servicing HTTP Requests on UNIX A main process spawning several child (httpd) processes Main process assigns requests to each httpd process Main Process Child Process 1 Child Process 2 Child Process 3 Child Process n
45 Servicing HTTP Requests on Windows Main Process Child Process Windows A parent process and a child process Child process handles workload as a multithreaded process (one request per thread)
46 MaxClients on UNIX Maximum number of simultaneous HTTP requests the IBM HTTP Server can server Default is 150, absolute minimum is 2048 Use low values (5-150) for CPU-intensive applications Let it go above 150 for database-intensive applications If your applications uses EJBs MaxClients will be high in most cases The more your go to back-end resources the higher the impact MaxClients will have on both, capacity and performance.
47 ThreadsPerChild on Windows Equivalent to MaxClients on Unix It defines the maximum number of simultaneous requests the child process should service Default is 50 If not using connection pooling it becomes directly proportional to the absolute maximum number of concurrent users allowed ThreadsPerChild (or MaxClients) is the regulating factor for the Web Server within the WebSphere Queuing Network
48 Finding a Tuning Pattern Start with a mid-range value MaxCleintes = 50 for CPU-intensive applications MaxClients = 150 for database-intensive applications Explore the effects of small and big deltas Try MaxClients += 10 Then try MaxClients += 1000 Watch for CPU utilization while testing If the CPU reaches 100% utilization you will need to refine your increments
49 Fine-Tuning Incoming Workload StartServers Default is 5 Let StartServers = MaxClients to free the CPU from having to create new child process MinSpareServers Default is 5 Keep it low (high values are bad for performance) MaxSpareServers Default is 10 Let MaxSpareServers = MaxClients
50 Fine-Tuning Incoming Workload MaxRequestsPerChild Default is Keep it high ListenBacklog Default is 512 No tuning is needed in most cases Increase if under a TCP SYN flood attack
51 HTTP Connections The IBM HTTP Server complies with the HTTP/1.1 Specification when it comes to connections HTTP connections can be persistent in the sense that they are reusable Just like database connections
52 Managing Persistent Connections KeepAlive Default is ON Turn off if you don t want persistent connections KeepAlive Timeout Default is 15 sec Decrease as load increases to avoid gridlock MaxKeepAliveRequests Default is 100 Increase for better performance Set to 0 for unlimited
53 Timeout Number of seconds it will take to receive GET requests TCP packets on POST requests Acknowledgements on TCP packet transmissions Default is 300 Increase if your application Goes to slow back-end systems Wraps legacy code Relies on applets to implement business logic Will be accesses by users over slow lines (dialup)

62 AL c(i) = (N ab(x) * N x ) + N asb where Absolute Cache Limit (AL c(i) ) N ab(lx) :total number of active beans on longest transaction N x : total number of concurrent transactions N asb : number of active session bean instances Use Resource Analyzer to monitor caching and change accordingly
63 Tuning (S c(i) ) S c(i) Determines the number of buckets in the cache has table Number of EJB instances in cache S c(i) < AL c(i) Normally you would want these two values to be equal This makes the entire cache available to the EJB Container service
64 Tuning (I c(i) ) Sets the cache clean-up schedule Value in ms It reduces cache size to the Preferred Limit (PL c(i) ) settings The idea is to free up hash-table entries Done via a background thread Increases if S c(i) increases
65 Tuning (ms p(wct) ) The Web Container assigns servlet and JDSP calls to threads Threads are created at startup time and are kept in a pool (ms p(wct) ) regulates how many will be available at any given time Increase for memory-bound applications This will speed them up The added CPU workload will be manageable Decrease for CPU-bound applications You would rather create threads as needed than maintain unused ones
66 Tuning (MS p(wct) ) Increase MS p(wct) for CPU-bound applications buy watch for CPU saturation Decrease Thread Inactivity Timeout to lower CPU utilization You don t want unused threads occupying valuable space Decrease for memory-bound applications This will reduce CPU overhead Creating new threads is not a problem for memory-bound applications
67 Transport Settings Maximum Keep-Alive Connections (MKA p(wcc) ) Maximum Requests per Live Connection (MR WCc ) Keep-Alive Timeout (KAT WCc ) I/O timeout (T i/o ) Connection Backlog (B WCc )
68 Tuning (MKA p(wcc) ) Maximum number of concurrent persistent connections across all HTTP transports Global scope In general MKA p(wcc) < MS p(wct) MKA p(wcc) < WS:MaxClients MKA p(wcc) < WS:threadsPerChild Default MKA p(wcc) = MS p(wct) Keep it that way for know
69 Tuning (MR WC ) Defines a connection s bandwidth Maximum number of requests over a connections Global scope Default is 100 Keep in mind that the actual capacity (EC WC ) of the Web Container is determined by MRpC as follows: EC WC = MKA p(wcc) * MRS C A capacity test for x virtual users, each producing y requests overall will be successful if and only if: EC WC > (x * y)
70 MKA p(wcc) and MR WCc MKA p(wcc) represents how many pipes are going to be available MR WCc represents the diameter of each pipe MKA p(wcc) HTTP Request HTTP Connection HTTP Connection HTTP Connection MKR WCc
71 KAT WCc and T i/o Keep-Alive Timeout Maximum amount of time (in seconds) the connection will wait for the next HTTP request Global scope Default is 5 sec Increase if connecting to slow legacy applications Decrease if CPU utilization is too high I/O Timeout Maximum amount of time (in seconds) dedicated to read/write while processing a request Global scope Default is 5 sec Increase if using object wrappers or connecting to CORBA objects
72 Tuning B WCc Maximum number of connections in buffer Discrete scope Default is 511 Decrease if CPU utilization is too high This may increase response time Increase to get more speed
73 Servlet Caching Settings Enables Servlet/JSP Dynamic Caching Servlet/JSP Cache Size S c(sj) Default Priority External Cache Groups
74 Tuning S c(sj) Maximum number of entries in the cache Entries refer to servlet/jsp instances created for individual clients Normally individual instances die one the client leaves Not when Dynamic Servlet/JSP Cache (DS c(sj) ) is enabled Set value to be very large Default is 1000 The more you have the better the cache will function Watch for memory usage
75 Advanced Settings Maximum In-Memory Count (MIM p(s) ) Invalidation Timeout (VT s )
76 Maximum In-Memory Session Count For non-persistent sessions It determines the number of sessions in the base session table Enable Allow Overflow to allow creating secondary tables Make it al least equal to WS:MaxClients (WS:ThreadsPerChild on Windows) For persistent sessions It specifies the size of the general cache Number of session updates to be cached Make it al least half the total number of session updates in the longest transaction
77 Tuning VT s Specifies the maximum session idle time Value must be at least two minutes Timer is accurate to within two minutes When using time-based Write Frequency: VT s > 2 * W s Global scope when not overridden by WAR deployment descriptors Always invalidate sessions explicitly
78 ORB General Properties Request Timeout (T ORBr ) Locate Request Timeout (T ORBlr ) Connection Cache Maximum (MS c(orbc) ) Connection Cache minimum (ms c(orbr) ) Thread Pool Size (S p(orbt) )
79 Tuning T ORBr Maximum waiting time for a request message Default is 180 sec Range goes from 0 to (maximum Java Int) Increase for CPU-bound applications Except if the EJB Container and the Web Container are deployed on the same machine Increase for database-centered applications and CORBA-intensive applications Use default value as a starting point
80 Tuning T ORBlr Maximum waiting time for a LocateRequest message Default is 180 sec Range goes from 0 to (maximum Java Int) Use same criteria as for Request Timeout
81 Tuning ms c(orbc) Number of TCP connections that must be in the connection cache in order for the ORB to clean up and connections that are not busy Default is 100 with a range from 0 to 255 The ORB uses TCP connections as transports for RMI calls EJBs with several short remotely exposed methods ms c(orbc) = 0.1 * ų ų = average number of remotely exposed methods for all EJBs deployed on the server EJBs with few long remotely exposed methods ms c(orbc) = 0.25 * ų
82 Tuning MS c(orbc) Maximum number of active TCP connections allowed in the connection cache table at any given time The default value is 240, with a range from 0 to 256. EJBs with several short remotely exposed methods 2 * ų < MS c(orbc) < 256 EJBs with a few long remotely exposed methods 4 * ų < MS c(orbc) < 256
83 Tuning S p(orbt) The new ORB is also thread-configurable One thread per RMI call specifies the starting size of the thread S p(orbt) pool for the application server One thread pool and cache per application server Threads should be picked from the pool and returned afterwards Creating and destroying threads is more expensive than pooling It makes the server CPU-bound Use same criteria as MS c(orbc) depending on how your EJBs are architected
84 Tuning S p(orbt) Consider selective EJB deployment if CPU utilization on the machine goes above 80% Set the value for S p(orbt) on each machine using the same rules as for MS c(orbc) Admin Domain EJB Server 1 EJB Server 2 A B C D A B C D
85 Data Source Settings Control connection pools Minimum Connection Pool Size (ms p(dsc) ) Maximum Connection Pool Size (MS p(dsc) ) Connection Timeout (T DSc ) Idle Timeout (IT DSc ) Orphan Timeout (OT DSc ) Prepared Statement Cache Size (S c(dsps) ) Auto Connection Cleanup
86 Tuning Data Sources Creating connections is expensive One process per DB2 connection in UNIX (ms p(dsc) ) settings: WS:MaxClient > MKA pwcc) < MS p(dsc) Same for WS:ThreadsPerChild Valid for session databases and data repositories ms p(dsc) settings: Default is 1
87 Tuning Data Sources Low settings for MS p(dsc) have shown to work better In UNIX environments: For session databases ms p(dsc) < 0.2 * MS p(dsc) For data repositories ms p(dsc) < 0.05 * MS p(dsc) TPS
88 Tuning S c(dsps) Experimental data on Windows 2000 shows performance increases when S c(dsps) > N DSps * γ) Where γ = min(ws:threadperchild, MS p(dsc) ) This rule may not hold in UNIX WS:MaxClients represents processes instead of threads MS p(dsc) represents also processes (one per connection) You will have to experiment with your applications to find the appropriate rule
89 Auto Connection Cleanup New in WAS 4.0 An algorithm that runs as a separate process that scans Data Source connections and tries to identify Idle connections Orphan connections Similar to the JVM s garbage collections mechanism Enabling it ensures healthy connection pools It increases CPU utilization Disable it if you know you re cleaning up connections explicitly
90 JVM
91 JVM Heap Size Probably the most critical element affecting JVM performance It determines garbage-collection heuristics Two settings Starting Heap Size (ms h(jvm) ) Maximum Heap Size (MS h(jvm) ) In general, ms h(jvm) = 0.25 * MS h(jvm)
92 Tuning MS h(jvm) and ms h(jvm) A small heap will force the JVM to collect garbage more often Garbage collection won t take long The opposite effect occurs with large heap sizes Large heap sizes improve throughput Consider MS h(jvm) = 256 for 4-way machines ms h(jvm) should stay within physical memory You can specify a minimum size and let the heap grow as needed No maximum value This doesn t work on all applications
93 Tuning the JIT Compiler and Garbage Collection Defaults JIT = on Asynchronous garage collection = on Class garbage collection = on Changes expressed as command-line arguments Requesting garbage collection (System.gc()) at the appropriate times may improve performance up to 15% on AIX Turning off asynchronous garbage collection (- noasyncgc) may improve performance for EJBbased applications on Solaris
94 DB2
95 Rules for Data Repositories Instance maxagents = Σ(maxappls) Databases maxappls = (MKA p(wcc) + MS p(dsc) ) * Clones Default is 40 buffpage = 2 * maxappls (minimum value)
96 Rules for Session Databases Independent sessions database and Data Source No c maxappls < MS p(dsc) When using clones maxappls < MS p(dsc) * Clones
