AJP - Database Problem

06-11-2010, 09:45 AM

Hello!

This morning i got an error with my open-xchange. In the open-xchange.log was this error:

Code:

I don't know the problem, but after a restart the system is working.

I also found a second problem.

Code:

What is the problem? Is there something wrong with my database-connection? Here my configdb.properties:

Code:

# ConfigDB Properties
# This file configures JDBC connections to the configdb. The configdb holds data
# about where to find context specific data.
# The driver properties should be kept at their defaults.

# useSeperateWrite must be true for mysql master slave replication setups
# and false if not.
useSeparateWrite=false

# the read connection must point to the database slave
readDriverClass=com.mysql.jdbc.Driver
# readURL holds the database host and the used schema name
readUrl=jdbc:mysql://192.168.17.244:3306/configdb
# username for the database user

# password for the database user

# The driver properties should be kept at their defaults.

# the read connection must point to the database master
writeDriverClass=com.mysql.jdbc.Driver
# readURL holds the database host and the used schema name
writeUrl=jdbc:mysql://192.168.17.244:3306/configdb
# username for the database user
writeProperty.1=user=openxchange

writeProperty.3=useUnicode=true
writeProperty.4=characterEncoding=UTF-8
writeProperty.5=autoReconnect=true
writeProperty.6=useServerPrepStmts=false
writeProperty.7=useTimezone=true
writeProperty.8=serverTimezone=UTC
writeProperty.9=connectTimeout=15000
writeProperty.10=socketTimeout=15000

# Timeinterval of cleaner thread in milliseconds. This thread removes idle timed
# out database connections and removes not used database connection pools.
# after each cleanerInterval.
cleanerInterval=10000

# Number of connections to keep open although they aren't used.
# This value is overwritten for OX databases from configdb. Sould be 0 so that
# no unnecessary connection are kept in the memory.
minIdle=0

# Number of maximum idle connections. More connections aren't pooled and closed.
# -1 stands for unlimited.
maxIdle=-1

# Maximum time in milliseconds a connection can be idle. If this time is 
# exceeded, the connection gets closed.
maxIdleTime=60000

# If exhaustedAction is set to BLOCK, not more than maxActive connections
# will be opened to the mysql database.
# This value is overwritten for OX databases from configdb.
maxActive=500

# If exhaustedAction is set to BLOCK, a thread will not wait for more than 
# maxWait milliseconds.
maxWait=10000

# Maximum time in milliseconds a connection will be used. After this time
# the connection get closed.
maxLifeTime=600000

# BLOCK: If maxActive number of connections is reached threads have to wait for a connection.
# FAIL: If maxActive number of connections is reached an exception is thrown.
# GROW: Open more connections even if maxActive is already reached.
# This value is overwritten for OX databases from configdb.
exhaustedAction=GROW

# Validate connections if they are activated. This is not necessary because the
# activation already includes a check if the connection isn't closed.
testOnActivate=false

# Check if connections can be reused after they are returned to the pool. 
testOnDeactivate=true

# Not useful for connections.
testOnIdle=false

# if testThreads is set to true, more information is logged to the Open-Xchange
# log files about database connections.  If this option is enabled the
# performance may degrade dramatically. The JVM has to generate then a lot of
# method call stack dumps.
testThreads=false

# Force use of write connections
# Must be true in Admin Daemon configuration!
writeOnly=false

Best regards

Hi,

those are no severe errors. The first informs, that an action did run for more than 1 monute. The second informs, that a database access took longer than 2 seconds. These are pretty common status messages.

Greetings
