• APEX setup guide
• APEXExport Overview

This walk-through assumes you have APEX 4.1 Listener and Oracle 10G XE or greater installed. If not, reference the links above.

We will break this walk-through up into 4 sections:

• Mounting a network share for the backup directory and configuring fstab
• Configuring APEXExport to correctly talk to your database
• Write a script to make sure your backup directories exist and export all of your applications
• Configure a cron job to run the script twice a day 7 days a week

Mounting a network share for the backup directory and configuring fstab
Create local mount point
mkdir /mnt/backup

Create connection file
nano /etc/cifspw
username
password


Edit fstab
nano /etc/fstab
//server.domain.com/share /mnt/backup cifs exec,credentials=/etc/cifspw,uid=root 0 0


Mount the directory
mount /mnt/backup

Configuring APEXExport to correctly talk to your database

You must run APEXExport from the utilities folder where you installed APEX
cd /usr/lib/oracle/xe/app/oracle/product/10.2.0/server/apex/utilities

Export the CLASSPATH
export CLASSPATH=.:${ORACLE_HOME}/jdbc/lib/ojdbc14.jar

APEXExport is run in the following syntax:
java oracle/apex/APEXExport -db localhost:port:SID -user schemaOwner -password yourPass -workspaceid workspaceID
port = 1521
SID = XE

schemaOwner can be found based on your version of APEX. If you are running 3.5 user = APEX_030500. If you are running 4.1 user = APEX_040100
Unlock user and set password through SQL*Plus as SYSTEM
SQL> ALTER USER APEX_040100 ACCOUNT UNLOCK;
SQL> ALTER USER APEX_040100 identified by yourPass;

workspace ID can be found from the SQL workshop utility
select workspace, schemas, workspace_id
from apex_workspaces;

Your APEXExport command should now run successfully by itself and look similar to
java oracle/apex/APEXExport -db localhost:1521:XE -user APEX_040100 -password yourPass -workspaceid 13541863513546

Write a script to make sure your backup directories exist and export all of your applications
Create a new script
touch apex_backup.sh
chmod a+x apex_backup.sh

The script I wrote creates a folder for the day of the week (Mon) and a folder in that folder for the time of day (AM/PM) since I want to backup 2 times a day 7 days a week. It then rolls over each week. The script performs the following steps.
1. Create variables for the backup directories
#/bin/bash

adir=/usr/lib/oracle/xe/app/oracle/product/10.2.0/server/apex/utilities
ddir=/mnt/backup/config/apex/backups/$(date +%A)
tdir="$ddir/$(date +%p)"

2. Make sure the working directory and path are correct
cd $adir
export CLASSPATH=.:${ORACLE_HOME}/jdbc/lib/ojdbc14.jar

3. Start the backup log and execute the APEXExport command
echo APEX Backup Started $(date) >> $adir/backup_log
java oracle/apex/APEXExport -db localhost:1521:XE -user APEX_040100 -password yourPass -workspaceid 13541863513546 >> $adir/backup_log

At this point the each application is exported in the form f101.sql f102.sql and so on (101 = application id).

4. Make sure backup directory is mounted
#Check if mount does NOT exist
if ! grep -qs '/mnt/backup' /proc/mounts; then
mount /mnt/backup
fi

5. Create backup directories
#Create backup directories
if [ ! -d "$ddir" ]; then
mkdir $ddir
fi
if [ ! -d "$tdir" ]; then
mkdir $tdir
fi

6. Move backups and copy logs to backup directory
#Copy backups and logs to backup directories
cp -f f*.sql $tdir
echo APEX Backup Completed $(date) >> $adir/backup_log
cp -f backup_log $tdir

So now that we know what each section of the code is doing here is the entire script:
#/bin/bash

#Copy backups and logs to backup directories
cp -f f*.sql $tdir
echo APEX Backup Completed $(date) >> $adir/backup_log
cp -f backup_log $tdir

Configure a cron job to run the script twice a day 7 days a week
Edit crontab as root
su
crontab -e

Add one job to run the script at 11:55am and another to run the script at 5:00pm
#APEXExport AM
55 11 * * * /root/apex_backup.sh >/dev/null 2>&1
#APEXExport PM
0 17 * * * /root/apex_backup.sh >/dev/null 2>&1

After a week you will have AM and PM backups for Mon – Sun.

It’s been 2 years and we finally hit the road on two sticky wheels again. This years motorcycle trip was the best. More unexpected and impassible dirt roads than ever before! More hammock slinging than ever before! And the usual amount of biscuits gravy and coffee.

This is our 4th loop around Colorado. The first two years were well traveled roads that made a nice loop of the state, clockwise one time, counter clockwise the other. We then planned on Zion, UT but it was way to hot so we sought higher ground. The 3rd year was a custom loop devised from some of the gnarliest twisting roads in Colorado. This time, we took those same roads to google maps and tweaked each route until there wasn’t a strait section for more that 10 miles. The consequences were unforgettable! and dirty!

Check out the motorcycle section to see pics from the most recent trip. Hero GoPro video coming soon!

We stopped for breakfast at Chasm Lake and that was the last time we could SEE the summit.

At the top of Lamb’s Slide just before the Exit Ramp to the Loft the clouds soared up towards us and engulfed everything above 1,300′. From that moment on we were climbing in the clouds. It was until we got back down to Chasm Lake that we were able to see more than 20 feet in front of us. While in the cloud it snowed for short periods of time. There is a solid snow field at the top of the Lamb’s Slide that is mostly avoidable to the left, however the rocks were slightly wet and icy in spots.

The Loft itself had patches of snow which was actually helpful on the return trip. Without much visibility we were able to retrace our steps like they were bread crumbs.

No view from the top but it was a very cool experience. Back at Chasm Lake we took a look behind us and I could not believe we were up there just hours earlier. It was a wonderful trip.
