Hi, We're using Derby DB (Version 10.8.2.2) in a larger project. Our database size is now around 12GB. It is running as network service and is used as the data backend for several Java web projects, that are connecting to the database using the network jdbc client. One of the projects is triggering nightly backups using the command:
CALL SYSCS_UTIL.SYSCS_BACKUP_DATABASE(?) Randomly (every 2 or 3 days) the backup cannot complete because of the following exception: Aug 13 00:03:14 srv- test-001 jsvc.exec[5953]: a:662)#012Caused by: org.apache.derby.client.am.SqlException: Cannot backup the database, got an I/O Exception while writing to the backup container file /mnt/backup/2012-08-13-00-00-00/bd/seg0/c9b1.dat.#012#011at org.apache.derby.client.am.Statement.completeExecute(Unknown Source)#012#011at org.apache.derby.client.net.NetStatementReply.parseEXCSQLSTTreply(Unknown Source)#012#011at org.apache.derby.client.net.NetStatementReply.readExecuteCall(Unknown Source)#012#011at org.apache.derby.client.net.StatementReply.readExecuteCall(Unknown Source)#012#011at org.apache.derby.client.net.NetStatement.readExecuteCall_(Unknown Source)#012#011at org.apache.derby.client.am.Statement.readExecuteCall(Unknown Source)#012#011at org.apache.derby.client.am.PreparedStatement.flowExecute(Unknown Source)#012#011at org.apache.derby.client.am.PreparedStatement.executeX(Unknown Source)#012#011... 21 more#012Caused by: org.apache.derby.client.am.SqlException: Java exception: 'No space left on device: java.io.IOException'.#012#011... 29 more The available space on the target device is more than sufficient. We already started the derby process with the Java Option "-Djava.io.tmpdir" to point to a directory residing on a partition with more space. This did not help. Do you have any suggestions? Which directories are used for running the backup and how much space needs to be availabe? Thank you, Stefan
