IV55434: CUSTOMIZATION OF TIMEOUT FOR REFRESHING SEMAPHORE DURING SYNCHRONIZATION.

APAR status

• Closed as program error.

Error description

• The default value is 3 minutes, but the customer should have a
  possibility to change that value. A new property will be added
  in collation.properties file with default value 180 (seconds)
  
  com.collation.ecmdb.semaphoreRefresh
  
  
  
  In this case it happens that the refresh is done rarer than
  3 minutes and finally it causes the failure of whole
  synchornization.
  
  Error on domain which will be seen if issue is encountered:
