    #put this in the file above
    service.pid="org.apache.jackrabbit.oak.plugins.segment.SegmentNodeStoreService"
    pauseCompaction=false

  2. in aem 5.6.1 to check if tar optimization (for example the default one which runs from 02 am to 05 am ) is running or not - check this: grep tar error.log |grep optim |grep Schedu
  3. ok...now coming to vi command - as you would all know the meaning of dd - which is to delete a line... and x - which is to delete a character... have you ever thought about as to how to delete a group of characters till a particular character Well the answer is: dt<that_character>.... so it can be like dt<space> if you want to delete till the next space character.
    give it a try and i am pretty sure you will like it... as they say there is no end to learning...
  4. Author login problems   [log message -  org.apache.sling.auth.core.impl.SlingAuthenticator handleLoginFailure: Unable to authenticate anonymous user]
    - try doing this: in system console configMgr search for : author sling authentication service - and then update the anonymous user with correct admin user and password... this may solve the issue
  5. Mapping - note that mapping run modes are always picked from start script run mode parameters... however even then sometimes you may have problems...jcrresolver might not show the correct mapping info - that means the mapping is not picked up from right place - having issue with mapping?
    here /system/console/configMgr check for - apache sling resource resolver factory
