原因:
atomikos的默认配置中 transactions.properties中:
# SAMPLE PROPERTIES FILE FOR THE TRANSACTION SERVICE # THIS FILE ILLUSTRATES THE DIFFERENT SETTINGS FOR THE TRANSACTION MANAGER # UNCOMMENT THE ASSIGNMENTS TO OVERRIDE DEFAULT VALUES; # Required: factory implementation class of the transaction core. # NOTE: there is no default for this, so it MUST be specified! # com.atomikos.icatch.service=com.atomikos.icatch.standalone.UserTransactionServiceFactory # Set base name of file where messages are output # (also known as the 'console file'). # # com.atomikos.icatch.console_file_name = tm.out # Size limit (in bytes) for the console file; # negative means unlimited. # # com.atomikos.icatch.console_file_limit=-1 # For size-limited console files, this option # specifies a number of rotating files to # maintain. # # com.atomikos.icatch.console_file_count=1 # Set the number of log writes between checkpoints # # com.atomikos.icatch.checkpoint_interval=500 # Set output directory where console file and other files are to be put # make sure this directory exists! # # com.atomikos.icatch.output_dir = ./ # Set directory of log files; make sure this directory exists! # # com.atomikos.icatch.log_base_dir = ./ # Set base name of log file # this name will be used as the first part of # the system-generated log file name # # com.atomikos.icatch.log_base_name = tmlog # Set the max number of active local transactions # or -1 for unlimited. # # com.atomikos.icatch.max_actives = 50 (原因) # Set the default timeout (in milliseconds) for local transactions # # com.atomikos.icatch.default_jta_timeout = 10000 # Set the max timeout (in milliseconds) for local transactions # # com.atomikos.icatch.max_timeout = 300000 # The globally unique name of this transaction manager process # override this value with a globally unique name # # com.atomikos.icatch.tm_unique_name = tm # Do we want to use parallel subtransactions? JTA's default # is NO for J2EE compatibility # # com.atomikos.icatch.serial_jta_transactions=true # If you want to do explicit resource registration then # you need to set this value to false. # # com.atomikos.icatch.automatic_resource_registration=true # Set this to WARN, INFO or DEBUG to control the granularity # of output to the console file. # # com.atomikos.icatch.console_log_level=WARN # Do you want transaction logging to be enabled or not? # If set to false, then no logging overhead will be done # at the risk of losing data after restart or crash. # # com.atomikos.icatch.enable_logging=true # Should two-phase commit be done in (multi-)threaded mode or not? # Set this to false if you want commits to be ordered according # to the order in which resources are added to the transaction. # # NOTE: threads are reused on JDK 1.5 or higher. # For JDK 1.4, thread reuse is enabled as soon as the # concurrent backport is in the classpath - see # http://mirrors.ibiblio.org/pub/mirrors/maven2/backport-util-concurrent/backport-util-concurrent/ # # com.atomikos.icatch.threaded_2pc=false # Should shutdown of the VM trigger shutdown of the transaction core too? # # com.atomikos.icatch.force_shutdown_on_vm_exit=false
修改默认配置中的:
com.atomikos.icatch.max_actives = 50------改为更大就可以解决
