VBox convert vmdk to vdi, resize, and grow win7 disk

stackoverflow

create a new ext4 partition in gparted

create a mount point for the new partition
sudo mkdir /media/win7ssd
sudo chown troy:troy /media/win7ssd
sudo chmod 700 /media/win7ssd

mount the partition
sudo vi /etc/fstab

     /dev/sdb3 /media/win7ssd ext4 defaults 1 2

sudo mount -a

Convert and resize the existing vmdk
sudo VBoxManage clonehd "/media/win7/Win7-disk1.vmdk" "/media/win7ssd/Win7-disk1.vdi" --format vdi
sudo VBoxManage modifyhd "/media/win7ssd/Win7-disk1.vdi" --resize 40000

update the ownership and permissions

sudo chown -R troy:troy /media/win7ssd
sudo chmod -R 700 /media/win7ssd

In virtualbox replicate the configuration but use the new disk

Oracle JDBC ReadTimeout QueryTimeout

If a query exceeds the oracle.jdbc.ReadTimeout without receiving any data, an exception is thrown and the connection is terminated by the Oracle driver on the client. Unfortunately the session will still be queued on the database and continue to wait for locks, hold any current locks, and complete any DML/PL*SQL procedures that are pending on the server-side of the orphaned connection. If an application, on a another connection, due to ReadTimeout exception, retries DML/PL*SQL  which requires locks, those queries will queue behind the initial DML/PL*SQL. This will increase the workload exacerbating the situation. On applications with retries, this can be observed by querying the v$session table  or gv$session on RAC and noting new sessions started periodically based on the ReadTimeout interval. The sessions may often have the same SQL_ID and/or SQL_HASH_VALUE. If stmt.setQueryTimeout(Seconds) is issued and the statement exceeds the timeout, it will atte...

Locks held on Oracle for hours after sessions abnormally terminated by node failure

If a session holds db locks and is abnormally terminated (no fin/ack), the locks will persist until the db session is closed, typically around 2 hours and 12 minutes with default network tcp_keepalive settings. Abnormally terminated does not include CTRL C or kill -9. The ojdbc6 driver apparently has a shutdown hook thread that closes the connections in graceful shutdowns. The OS apparently closes the connections when processes are killed. Abnormally terminated might include power failure, firewall failures, Out Of Memory, OS/kernel crash, network connection failure, JBoss or other server node failure, etc. This was easily reproduced by creating a  process that connected to the db and updated a record but did not commit. While the first process was waiting, a second process with a contending update was started which blocked on the first update. The first clients network cable was then disconnected. The second clients transaction waited for approximately 2 hours until the databa...
