Please  Note  IBM’s  statements  regarding  its  plans,  direc/ons,  and  intent  are  subject  to  change  or  withdrawal  without  no/ce  at  IBM’s  sole  discre/on.  Informa/on  regarding  poten/al  future  products  is  intended  to  outline  our  general  product  direc/on  and  it  should  not  be  relied  on  in  making  a  purchasing  decision.    

The  informa/on  men/oned  regarding  poten/al  future  products  is  not  a  commitment,  promise,  or  legal  obliga/on  to  deliver  any  material,  code  or  func/onality.  Informa/on  about  poten/al  future  products  may  not  be  incorporated  into  any  contract.  The  development,  release,  and  /ming  of  any  future  features  or  func/onality  described  for  our  products  remains  at  our  sole  discre/on.

Page 9: WTUI10 - Effective Administration in IBM Integration Bus

Significant  Tool  changes  in  V10  Open  Beta  

•  Single  install  package  and  single  installed  component  –  Unit  test  integra/on  node  automa/cally  started  with  IIB  development  tool  –  Can  create  addi/onal  integra/on  nodes  as  required  

•  No  longer  any  MQ  pre-­‐requisite  –  All  exis/ng  MQ  use-­‐cases  s/ll  work  (and  now  support  remote  MQ  connec/ons)  –  All  administra/on  done  through  the  web  UI  rather  than  the  Integra/on  Explorer  –  Remote  administra/on  commands  need  to  point  at  the  integra/on  node’s  administra/on  

port  rather  than  the  queue  manager  

•  Uses  a  single  command  ‘iib’  –  e.g.  iib  studio,  iib  help,  iib  list  –  Equivalent  of  ‘mqsicommand’  is  ‘iib  command’  –  Exis/ng  commands  con/nue  to  work  

(no/ng  remote  administra/on  caveat  above)  

Page 10: WTUI10 - Effective Administration in IBM Integration Bus

Development  Lifecycle  and  Environments  

•  Integra>on  Developer  –  Develops  message  flows,  message  

models  etc.  –  Unit  Tests  on  local  machine  –  Creates  archive  (BAR)  files  

containing  required  artefacts  

•  Administrator  –  Customizes  BAR  for  target  

environment  (message  flow  proper/es  including  queues,  database  names  etc.)  

–  Deploys  BAR  to  target  environment  –  Management  and  opera/onal  control  

Development   Test   QA   Produc/on  

Page 11: WTUI10 - Effective Administration in IBM Integration Bus

Common  Administra>ve  Tasks  

•  Planning  and  configura>on  –  Bringing  a  new  integra/on  node  online  –  Making  an  integra/on  node  highly  available  –  Planning  for  disaster  recovery  –  Securing  an  integra/on  node  

•  Managing  integra>on  nodes  –  Deployment  and  redeployment  –  Understanding  behaviour  –  Op/mizing  and  tuning  –  Migra/on  –  Maintenance  

Page 12: WTUI10 - Effective Administration in IBM Integration Bus

Bringing  a  new  integra>on  node  online  

•  Typical  steps  required  –  Preconfigura/on  (e.g.  OS,  userids)  –  Installa/on  (MQ,  IIB,  addi/onal  sojware)  –  Crea/ng  the  integra/on  node  –  Crea/ng  integra/on  servers  –  Crea/ng  Configurable  Services  –  Deploying  BAR  files  –  Addi/onal  configura/on  (e.g.  security,  userids)  

 •  And  don’t  forget:  

–  Documenta/on  –  Scrip/ng  –  Virtualiza/on  

Page 13: WTUI10 - Effective Administration in IBM Integration Bus

Scrip>ng  and  Automa>on  

•  Four  general  approaches  for  IIB  provisioning  –  Crea/ng  and  configuring  brokers  manually  –  Use  of  commandline  tools  from  within  scripts  (e.g.  shell  scripts,  Jenkins,  Ant,  Maven…)  –  Hypervisor  images  for  deployment  directly  on  public  or  private  cloud  –  Use  of  technologies  such  as  Chef  and  Puppet  for  all  environments  (cloud,  non-­‐cloud)    

•  Choose  an  approach  that  enables  your  environment  to  be  reproduced  easily    

<project> <target name=“deploy”> <cvs command=“checkout” … /> <mqsipackagebar … /> <mqsiapplybaroverride … /> <mqsideploy … /> </target> </project>

Page 14: WTUI10 - Effective Administration in IBM Integration Bus

Making  the  integra>on  node  highly  available  

•  How  do  I  ensure  that  the  integra>on  node  is  con>nually  processing  messages?  –  Ac/ve/Ac/ve  vs.  Ac/ve/Passive  –  Agree  SLAs  with  the  business  (%  up/me)  

•  The  integra>on  node  includes  restart  recovery  of  integra>on  servers  –  But  this  is  usually  not  sufficient  on  its  own  –  Does  not  cover  machine  restart  

•  Two  main  op>ons  –  Third-­‐party  solu/ons  (e.g.  VCS/HACMP/MSCS)  –  Mul/-­‐instance  queue  managers  and  integra/on  nodes  

•  Distributed  Cache  –  Built  in  cache  support  in  8.0.0.1  and  later.    –  Enables  HA  scenarios  

Page 15: WTUI10 - Effective Administration in IBM Integration Bus

Planning  for  disaster  recovery  

•  What  would  you  do  if  your  primary  WMB  loca>on  goes  down?  

•  Distribute  WMB  to  mul>ple  sites  if  possible  –  This  introduces  data  replica/on  and  latency  concerns  

•  Keep  DR  concerns  separate  from  HA!  –  HA:  Systems  at  a  single  site  with  a  single  configura/on  

DR:  Systems  at  mul/ple  sites  with  replicated  configura/ons  –  An  HA  failover  can  be  a  planned  ac/vity  –  DR  is  unplanned.  

Page 16: WTUI10 - Effective Administration in IBM Integration Bus

Another  approach  to  disaster  recovery…  

•  Consider  an  architecture  where  no  one  service  was  taken  for  granted…  –  Trea/ng  all  elements  of  a  system,  regardless  of  business  u/lity,  as  ‘disposable’  –  Forces  you  to  design  in  a  way  that  enforces  resilience  and  scalability  –  Requires  up-­‐front  effort,  but  takes  many  concerns  off  the  table  (e.g.  backup)  

IIB  IIB  IIB  

•  IIB  enables  an  architecture  that  removes  single  points  of  failure  –  Even  easier  with  IIB  V10  Open  Beta  due  to  remote  queue  manager  support  

Page 17: WTUI10 - Effective Administration in IBM Integration Bus

Cloud  Integra>on  •  The  idea  of  disposability  is  facilitated  by  cloud…  

–  Trea/ng  compu/ng  resources  like  u/li/es  such  as  gas,  electricity  –  Pay  for  only  what  you  use  

•  IIB  has  a  range  of  IaaS  cloud  op>ons  –  Private  Cloud  

•  IBM  Integra/on  Bus  Hypervisor  Edi/on  •  IBM  Workload  Deployer  •  Pure  Applica/on  Systems  Papern  •  Chef  scrip/ng  

–  Public  Cloud  •  Support  for  public  cloud  providers,  e.g.  Sojlayer  •  Chef  scrip/ng  

–  Future  plans  around  IaaS  (e.g.  Sojlayer),  PaaS  (e.g.  Bluemix)  and  SaaS  connec/vity  

•  Consider  virtualiza>on  for  new  environments  –  Makes  it  easy  to  provision  systems  (and  restore  known  state!)  –  Understand  maintenance  and  performance  aspects

Securing  WMB  and  IIB  

•  Simplified  administra>ve  security  •  3  levels  of  authorisa>on  for  administra>ve  ac>ons  

–  Reading  (e.g.  View  integra/on  node  proper/es  -­‐  mqsilist)  –  Wri/ng  (e.g.  Change  integra/on  node  proper/es  -­‐  mqsicreateexecu/ongroup)  

–  Execu/ng  (i.e.  star/ng  and  stopping)    –  See  IIB  Knowledge  Center  topic  bp43540  for  more  details  

•  On  two  object  types:  –  “Integra/on  node”  and  “Integra/on  servers”  

•  Administra>ve  Security  is  not  enabled  by  default  –  Enable  through  mqsichangebroker  /  mqsicreatebroker  

•  Access  controlled  using  MQ  queues  on  the  integra>on  node’s  queue  manager  –  Give  authority  to  users  or  groups

Page 20: WTUI10 - Effective Administration in IBM Integration Bus

Managing  what’s  deployed  

•  It  can  be  difficult  to  understand  what  individual  deployed  resources  are  used  for  •  Applica>ons  and  libraries  can  allow  you  to  understand  why  each  file  is  there  

–  Applica/on:  Encapsulates  a  single  use  case  or  scenario  –  Library:  Promotes  re-­‐use  of  a  shared  set  of  files  

–  Libraries  are  sta/cally  bound  to  the  applica/on  (V8,  V9,  V10  OB)  or  shared  (V10  OB  only)  

•  Concepts  are  shared  between  developers  and  administrators  –  The  developer  chooses  to  create  an  applica/on  or  library;  the  collec/on  is  then  carried  all  the  way  through  

to  the  run/me  

Page 21: WTUI10 - Effective Administration in IBM Integration Bus

Backing  Up  

•  Consider  using  mqsibackupbroker  to  backup  the  integra>on  node’s  configura>on  –  Ideally,  ajer  all  configura/on  changes  –  Best  run  when  stopped  –  But  can  be  used  whilst  ac/ve  as  long  as  not  undergoing  configura/on  changes  

•  Also  consider  any  other  required  resources,  for  example:  –  Database  tables  –  Source  artefacts  (message  flows,  BAR  files)  

•  Ensure  regular  restore  tes>ng  –  Prove  your  process  works  

•  Paeern  to  recons>tute  message  flows  from  a  running  integra>on  node  –  Available  on  MQSeries.net  

Page 22: WTUI10 - Effective Administration in IBM Integration Bus

Understanding  integra>on  node  behaviour    •  The  tools  include  a  lot  of  informa>on  that  is  useful  to  the  administrator  

–  Administra/on  queue  and  log,  Message  flow  and  resource  sta/s/cs  –  Warnings  when  features  that  affect  performance  are  enabled  

•  Use  this  informa>on  to  understand  recent  configura>on  changes    

−  How  the  integra/on  server  is  performing,  connected  endpoints,  etc.  

Page 23: WTUI10 - Effective Administration in IBM Integration Bus

Understanding  integra>on  node  behaviour  •  The  Ac>vity  Log  shows  you  all  recent  ac>vity  on  a  message  flow  or  resource  manager  

–  For  example,  “Show  me  all  recent  JMS  ac/vity”  •  Visible  in  Integra>on  Explorer  and/or  wrieen  to  a  file  •  Customisable  rota>on  rules  (based  on  age  or  size)  and  content  

Page 24: WTUI10 - Effective Administration in IBM Integration Bus

Op>mizing  and  tuning    

•  The  tools  allow  you  to  modify  the  configura>on  opera>onally    •  These  tweaks  more  efficient  to  make  than  modifying  message  flows    •  Encourage  developers  to  create  message  flows  that  enable  opera>onal  tweaks  to  be  made  

–  User-­‐defined  proper/es,  Configurable  Services,  User-­‐defined  configurable  services,  Policies  

Page 25: WTUI10 - Effective Administration in IBM Integration Bus

Managing  Unresponsive  Integra>on  Flows  §  Target  unresponsive  flows  through  policy  to  improve  overall  system  reliability  

–  Addi/onal  WLM  op/on  aimed  at  unresponsive  integra/on  flows  –  An  integra/on  flow  can  become  unresponsive  for  mul/ple  reasons  

•  e.g.  Wai/ng  for  external  system,  infinite  loop,  deadlock,  malformed  XML  

§  Flexible  configura>on,  ac>ons  and  repor>ng  op>ons  –  Specify  threshold  at  which  flows  are  considered  unresponsive,  e.g.  30  seconds  for  processing  

•  Configured  via  WLM  policy,  or  directly  on  the  flow  in  the  BAR  file  

–  Define  ac/on  to  trigger  when  flow  considered  unresponsive  •  Administra/ve  no/fica/on  through  a  new  “/meout  exceeded”  event  message  

–  If  flow  eventually  con/nues  through  to  comple/on,  a  second  event  is  published  •  Restart  the  integra/on  server  (execu/on  group)  on  which  the  unresponsive  flow  is  running  

–  New  command  op/on  to  forcibly  stop  integra/ons  manually:  mqsistopmsgflow –f

Version-­‐to-­‐Version  Migra>on  § Migra>on  to  IIB  V9  from  WMB  V6.1,  V7  and  V8  

–  All  development  assets  (e.g.  message  flows,  ESQL,  DFDL,  Java,  Maps  and  XSLT)  import  directly  •  Right-­‐click  convert  ac/on  for  pre-­‐V8  maps;  some  manual  tasks  may  be  required  

–  Migrate  brokers  using  a  single  command,  or  create  new  integra/on  nodes  for  phased  migra/on  •  No  redeployment  necessary  when  using  built-­‐in  migrate  command  •  All  exis/ng  BAR  files  can  be  deployed  to  IB  V9  integra/on  nodes  without  change

§ Migra>on  commands  for  in-­‐place  migra>on  –  Includes  migra/on  of  configura/on  data  including  databases,  queues  and  registry  –  Forwards  and  backwards  migra/on  of  exis/ng  components,  in  situ  

•  mqsimigratecomponents command  (includes  –t op/on  for  rollback  to  V7  and  V8)

§  Flexible  co-­‐existence  op>ons  remove  the  need  for  addi>onal  hardware  when  migra>ng  –  IB  V9  co-­‐exists  on  the  same  OS  with  all  previous  MB  versions  –  MQ  V7.5.0.1  required  for  all  IB  V9  integra/on  nodes  

•  MQ  V7.5.01  supported  with  V7  and  V8  brokers  for  the  purposes  of  V9  migra/on  •  For  V6.1  migra/on,  upgrade  MQ  and  MB  simultaneously

Maintenance    

•  Schedule  regular  maintenance  windows  –  IBM  recommends  that  you  are  on  the  latest  maintenance  level  –  Plan  exactly  what  will  be  applied  and  when  –  A  highly  available  environment  ensures  that  there  is  no  down/me  

Page 28: WTUI10 - Effective Administration in IBM Integration Bus

Summary    

•  We  have  discussed  a  number  of  different  ways  that  help  ensure  that  administra>on  is  trouble-­‐free  

•  My  Top  Tips  

– Always  ensure  your  environment  is  reproducible  – Treat  DR  and  HA  separate  – Ensure  regular  backups  – Encourage  developers  to  create  message  flows  that  enables  opera/onal  tweaks  to  be  made  

– Schedule  regular  maintenance  windows
