Backup Process and Data Restoration


Introduction

The TPP backup feature backs up all TPP data folders on to a storage device which can
be used to recover data in case of problems with the TPP server. TPP data folders include
TPP server data, the Apache Tomcat data, and the MySQL database. The backup feature
provides options to backup all or a subset of this data. With the release of TPP version
4.2, live backup is possible without taking the servers off line. The backup process
creates a log file which can be used in case of failure to figure out where the error has
occurred.

Backup Processes

There are different ways to perform backups with TPP. The first 2 are the most
commonly used. They are all outlined below:

• Schedule an auto backup for TPP, Tomcat and a live or non-live backup for MySQL
with the TPP web client. Scheduling an auto non-live backup may interrupt the
application as the servers are shut down during the process. It is recommended to use
live backups.
• Perform a backup during a TPP upgrade as recommended during a prompt.
• Execute the TPPServerBackup.bat script in this directory (the bin directory of your
TPP install) typically located in the "c:\Program Files\JDSU TPP\bin". (or c:\Program
Files\Acterna FDM-250\bin.) When executing this with no parameters, the script will
give you instructions on usage.
• Execute the TPPServerBackup.bat script regularly. Each execution of this script will
restart the TPP, Tomcat, and MySQL Servers. It is recommended to use the live
backup option to backup the MySQL database without taking the server down.
• Auto Scheduling using Microsoft Scheduler.

Note:

It is recommended that the Apache Tomcat service should not be terminated at any time
for the TPP application to run properly. If there is a need to terminate the Apache Tomcat
service, always use the Control Panel to stop and restart it. Do NOT
use the “End
Process” command via the Task Manager to terminate Apache Tomcat. If there is a
scheduled backup process running, using “End Process” to terminate Apache Tomcat will
not terminate the backup process.

I. Auto Schedule using the TPP Web Client

Using the TPP web client, it is easy to schedule the process for backups and database
optimization. This is the recommended method.

Define the backup destination directory, number of backup copies to save before
overwriting the last one, what directories need to be backed up, and the start and end
dates for the backup jobs.

It is very flexible to edit or delete the old backup copies and view log files for backups.
The Web client displays the status, cause of failure if any, last date when the job was run
and the next scheduled date when the job will run. It gives you complete information
necessary to run backups.

The following are the steps to schedule the automatic backups in the Web client.

1) Login to the TPP Web client and click on the “system preferences” link in the left
panel.


2) Click on “schedule TPP backups” in the right panel.

3) Click on the “ADD” link at the top.





4) Fill in the form and click on “Save”.
a) Task Name: - Name for Backup
b) Backup Destination Directory: - Directory to store backups
c) Select one of the following radio buttons.
• Reuse destination folder for each backup
• Append count suffix to destination folder for each backup
• Append date & time suffix to destination folder for each backup

d) Advanced Settings

Select at least one operation as shown below.


Note: Choosing the “Delete ArchiveWorkOrderReports Files” or “Delete TPP
and Tomcat Log Files” options will permanently delete the respective files
from your server. Use these options when you are absolutely sure that you no
longer need these files. These files can be restored only if you have also
chosen the “Backup ArchiveWorkOrderReports Files” and “Backup TPP and
Tomcat Log Files” options.

e) Frequency: - How often do you want the process to run?
f) Time of Day: - What time of day do you want the process to run?
g) Scheduled Start Date: - The start date of the scheduled backup.
h) Scheduled End Date: - The end date of the scheduled backup. If blank, it runs
for ever.
i) Check Disk Space upon Save – Whether TPP should check if sufficient disk
space is available now (when “Save” is clicked”) for taking the specified
future backup.
j) Click on “Save” at the bottom when you are done.

If changes are necessary to the scheduled backup process, click on the “Edit” link in right
most column in the job row. Click on “Delete” link in right most column in the job row to
delete a scheduled backup job. Click on the “View Log” link to see the log files for a
backup job.

II. Auto Schedule using TaskScheduler.bat

Note: For some Windows XP Home versions, TaskScheduler.bat doesn’t work as XP
Home doesn’t allow you to schedule commands from the command prompt. Use step II
instead.

1) The “bkup.properties” file should exist in the directory from where the script is
launched or in the same folder as TaskScheduler.dat. If the property file is empty
then the script runs with default options. Enter the following in the bkup.properties
file:

TASK_NAME=JDSU TPP Backup
TASK_PATH=c:\program files\JDSU TPP\bin
(In case of upgrade setups it could also be TASK_PATH=C:\TPP\Acterna
FDM-250\bin)

You can change the task name to anything you like and make sure the task path is a
full path to TPPServerBackup.bat. If the properties file is not present then the script
will use the above mentioned defaults.

2) At the command line run the following to schedule a task

TaskScheduler.bat -create

When the above command is executed, the script prompts you to enter your logon
password. Enter your password. By default the task will be associated with the
logged-in user. Make sure you have necessary privileges to run the task.

Running this command will auto schedule the TPP backup process for daily
backups. If you like to schedule jobs other than daily basis then follow the steps
outlined in “Scheduling using Microsoft scheduler”.

3) To delete a scheduled task run the following command

TaskScheduler.bat –delete

The name of the task is read from the bkup.properties file and the file should be in
the same folder as the script. If no properties file is present, the script tries to delete
the task with the default name “JDSU TPP BACKUP”.

IV. Running TPPServerBackup from Command Prompt

1. Using the properties file

The “bkup.properties” file should exist in the directory from where the script is
launched or in the same folder as TPPServerBackup.dat. If the property file is empty
then the script runs with the default options. If the script does not find
bkup.properties file in any of the above mentioned locations then it stops. The
following are the keys that a bkup.properties file can have:

TPP_DIR=c:\Program Files\JDSU TPP
(Previous release TPP_DIR=c:\TPP\Acterna FDM-250)
MYSQL_DIR=c:\Program Files\MySQL\MySQL Server 5.5
WINDOWS_DIR=c:\WINDOWS
BACKUPPREFIX_DEF=c:\Program Files\JDSU TPP
(Previous release BACKUPPREFIX_DEF=c:\TPP\Acterna FDM-250)
BACKUPMID_DEF=-DB_Backup
BACKUPSTOSAVE_DEF=7
DO_TPP=0
DO_TOMCAT=0
DO_MYSQL=1
DO_WINDOWS=0
DO_LIVEBACKUP=1
DO_DBOPTIMIZE=0
TPP_LOG=c:\temp\backup.log
￿ For MySQL live database backup enter the following in
bkup.properties
DO_MYSQL=1
DO_LIVEBACKUP=1
￿ For DBOptimization enter the following in bkup.properties
DO_DBOPTIMIZE=1
￿ Execute the TPPServerBackup.bat script
DO_ARCHIVEWORKORDER=1
DO_PURGEWORKORDER=1
DO_ARCHIVELOGS=1
DO_PURGELOGS=0
ARCHIVEWORKORDERDAYS=30
PURGEWORKORDERDAYS=30
ARCHIVELOGSDAYS=30
PURGELOGSDAYS=30

If the bkup.properties does not exist in the same location as TPPServerBackup.bat,
specify the path to the properties file using –bkpProp option as follows:

TPPServerBackup.bat –bkpProp “C:\temp\bkup.properties”

2. Using command line

TPPServerBackup.bat –mysql “C:\program files\MySQL\MySQL Server 5.5” –
liveBackup



I. Optional Solutions

1. Using MySQL Administrator to schedule backup.
This option will backup the MySQL database only. You cannot do a backup of
the file system. You cannot backup the property file or Meters_Home with this
option.

2. Auto Backup for MySQL by swordsky software (Not supported by JDSU)
Auto Backup for MySQL is a powerful Windows program that makes it easy to
schedule the backing up and restoring of your remote and local MySQL
databases. It's easy to back up one or many MySQL databases, and restore them
to the same server, or to any server.

http://www.swordsky.com/pro_edition.html


3. Vembu StoreGrid (Not supported by JDSU)
Vembu StoreGrid is Disk to Disk (D2D) data backup software primarily used for
online backups. When you installed StoreGrid in Windows, StoreGrid
automatically starts as a Windows Service or a Windows Application (default
option) depending upon the option you chose during the installation.

V. Recover Database from Live Backup

WARNING: this chapter does not describe the Meters_Home, cfg, and OTHER file
restoration, that is described in the next chapter. This should be done before restarting
the TPP server at the bottom of this page.

If the live backup option in the web client is selected or the “liveBackup” option is used
with TPPServerBackup.bat, restore the database from the database.sql file.

NOTE: this assumes a running MySQL installation. In order to restore your MySQL
installation or create a new MySQL data directory, you can run the TPP installer to
“upgrade” to the same version while selecting the MySQL install option. An upgrade
will give an error if a previous data directory is not found, but will still successfully
create one.

1) Select Start -> Control Panel. Double click on Administrative Tools, then on
Services.
NOTE: Meters cannot synchronize with TPP while the server is shut down.
2) Select Apache Tomcat and press the stop icon. The TPP service will be stopped.
3) There is no need to stop the MySQL server, though restarting MySQL is needed if
restoring the my.ini file is done as described in the next chapter.
4) Go to the bin directory in the MySQL install folder.
5) For example if MySQL is installed at c:\Program Files then go to
a. C:\Program Files\MySQL\MySQL Server 5.5\bin>

6) At the prompt run the following command
mysql –uroot < “FILE_PATH\database.sql”

The * FILE_PATH is the full path to backup folder that has the database.sql file.

Restart the TPP server
To restart the server
1) Select Start>Control Panel; Double click on Administrative Tools; Double click
on Services.

VI. Recover Database, configuration, and
Meters_Home from Non-Live Backup

Shut down the TPP and MySQL servers

1) Select Start -> Control Panel. Double click on Administrative Tools, then on
Services.

NOTE: Meters cannot synchronize with TPP while the server is shut down.
2) Select Apache Tomcat and press the stop icon. The TPP service will be stopped.
3) Select MySQL and press the stop icon. (non-live backup specific step)
4) Locate the latest good backup folder containing your TPP data.
5) Locate the various BACKUP directories (folders) that were saved to a safe
location.

NOTE: DO NOT accidentally delete these folders in following steps.

The TPP version for the backup must match the TPP version for the current
installation.

Replace the Meters Home and cfg directories (if needed)

The Meters_Home folder mostly contains configuration files and firmware
deployments deployed from the TPP Web Client that haven’t been synchronized
yet for certain meters. Restoring it should be done when doing a server move.
It is the administrator’s choice if restoring it from a backup should be done
when there exists a newer last-active version with newer deployments (e.g. after
a harddrive failure that may have affected other data). If not restoring this, then
it is recommended to re-deploy important and/or recent deployments, like
channel plans and limit plans, to all meters.

The cfg folder contains many files:
• Only cfg file to restore for most users:
o configuration.properties

• Files containing system defaults that are never customized (no need to
restore over a fresh install):
o channelplan folder
o default_limitplan folder
o examples folder
o savedQueries folder
o server.xml
o key.properties (rarely user configured)

Page 21 of 25
TechComplete™ Test Productivity Pack (TPP)
Backup Process and Data Restoration
21
• Files created by a fresh install or an upgrade (usually just refer to these
files when filling out panels in the installer):
o BillingSystem.properties
o FDM-250.lic (license file installed during an install)
o webapp.properties (contains values that shouldn’t be upgraded
upon a server move)
o windows.properties (contains a value that shouldn’t be
upgraded upon a server move)
• File automatically created upon every TPP startup:
o mysql.info

1) In the JDSU TPP folder (or Acterna FDM-250 folder), move any files or folders
located within the Meters Home and cfg directories (folders) to a tmpSave
directory. The placement of the JDSU TPP (Acterna FDM-250) folder was
determined when TechComplete™ Test Productivity Pack was installed. It is
typically located in the C:\Program Files folder. (An upgrade from TPP v4.8
may have placed this file in the C:\TPP directory.)

2) COPY the BACKUP Meters Home and cfg directories (folders that you
formerly copied to a safe location) into its original location within the JDSU
TPP (or Acterna FDM-250) folder.

NOTE: When copying over a folder that already exists with the same name, you
may be required to overwrite the existing folder with the new [backup] folder.

Replace the Database directory (non-live backup specific step)

1) It is critical that the MySQL service is stopped (as described at the top of this
chapter) whenever copying files in to or out of the MySQL data directory.

2) In the MySQL Server 5.5 install folder, delete ALL files and folders located
within the data directory (folder) or move to a temporary folder outside of the
data directory. The data directory location above is assuming your installation
left the datadir property unchanged in your my.ini configuration file located in
the OS install folder, typically c:\Windows.

3) COPY the BACKUP directories into their original location within the data
folder.

Replace OTHER files

In the BACKUP folder, there are other files that may contain customizations for some
customers.

1) The WorkOrderReports folder may contain unparsed CMRS billing system files
that typically belong in C:\Program Files\JDSU TPP\WorkOrderReports or

Page 22 of 25
TechComplete™ Test Productivity Pack (TPP)
Backup Process and Data Restoration
22
C:\TPP\Acterna FDM-250\WorkOrderReports. Files in this folder are usually
parsed by TPP every 2 minutes and removed, so it is rare for files to be in this
backup folder.
2) The windows folder may contain the my.ini MySQL configuration file that
typically is located in C:\Windows. JDSU only supports 2 customizations to
this file, so many customers do not need to restore this upon a server move:
a. A manually moved MySQL data directory is supported via changing
the datadir property.
b. The “system preferences” – “database configuration” allows
enabling “Remote SQL Access” by removing the bind-address
property from this file.

3) The tomcat folder may contain various configuration files that typically are
located in various folders within c:\Program Files\Apache Software
Foundation\Tomcat 7.0.
a. It is important to restore all of the following, when the hostname/IP
address have not changed, so users don’t have to re-install the
certificate used for logging in to TPP Web. These are located in the
tomcat\conf backup folder.

i. In particular the certificate file “ActernaTPP.p12” which
needs to be placed in the conf directory within the tomcat
installation directory.

ii. Also the file “jdsu.cer” which needs to be placed in the
following directories within the tomcat installation directory.

1. conf
2. webapps\ActernaTPP
Note: there is a duplicate backup copy of this file in the
tomcat\webapps\ActernaTPP backup folder.


b. It is very important to restore the following at sites using Secure
Sync™ with meter certificates. Not restoring this will invalidate all
meter certificates for the site, thus preventing the meters from
synchronizing outside of the internal company Internet until all of
the meter certificates are regenerated via TPP Web and the meters do
a sync on the internal network.
i. The certificate file “ActernaTPP_certPort.p12
” needs to be
placed in the conf directory within the tomcat installation
directory.
c. All other files in the tomcat/conf and tomcat/webapps folders are not
recommended to be customized, and thus don’t need to be restored
when moving servers.

VII. Example TPP 4.7/4.8 (on a 32 bit Server) upgrade to
TPP 5.0 (on a 64 bit Server)

Note: reviewing the previous chapter is recommended, since it has some
additional details.

1) Working with your IT, upgrade the Java JRE browser plug-ins for your TPP
Client users. This is needed if your users don’t meet the new minimum
(1.6.0_33) and/or recommended (1.7.0_17) version as seen in the TPP 5.0
release notes. This upgrade will be needed to use the Remote DSAM
application and view certain measurement file graphs in TPP Web, including
those graphs in Home Certification files. Note: TPP 4.8 is not compatible with
1.7 JREs, so it may be better to delay this step until later.
2) To reduce downtime, it is recommended to setup a new server. Server
specifications can be found in the TPP/FDM-250 Getting Started Guide,
including which 64 bit operating systems are supported.
a. Configure the AntiVirus as specified in the TPP Release Notes.
b. Configure the Server Firewall allowing connectivity as described in
the Secure Sync™ Application Note.
3) Send an e-mail request to
licensingkey@jdsu.com

to get your previous TPP
license file converted to work with the new server. You will need the MAC
address of your new server for this request.
4) Install TPP 5.0 on the new server:
5) Assuming you’ll later change the new server’s IP Address and hostname to
match the old server’s values:
6) If your TPP Web users refer to your old TPP server by multiple hostnames
and/or IP Addresses, then specify those in the installer when prompted. It is
important for all names and addresses be registered when creating the login
page’s certificate due to browser TPP/SSL login requirements. Note: localhost
and 127.0.0.1 don’t have to be specified, as they are automatically included for
new certificates.
7) Otherwise, use the hostname or IP Address value previously specified (see the
webapp.properties file from your old TPP’s cfg folder) when prompted by the
installer. For this scenario, restore the ActernaTPP.p12 and jdsu.cer file (as
previously described) after the install is complete.
8) If enabled on the old server, use the “system preferences” – “database
configuration” page to enable “Remote SQL Access”
9) Stop the Apache Tomcat Service (which runs TPP)
10) Install the configuration.properties and ActernaTPP_certPort.p12 files as
previously described.
11) Update the datadir property in the my.ini file and move the data directory if a
custom MySQL data directory is needed; requires a MySQL restart.

i. Start the Apache Tomcat service (TPP) and test a web client
login: e.g.
http://localhost/ActernaTPP

Using ID=administrator and Password=fdm250
ii. Stop the Apache Tomcat Service and then MySQL
iii. Warn meter and web users of the server downtime.
iv. Stop the fdm250service and then MySQL services on the old
server
v. It is also recommended to disable those Windows Services to
prevent accidental usage of this server again.
vi. Copy the MySQL data folder and TPP Meters_Home folder
from the old to new server, keeping in mind that the old
default install locations (in c:\TPP) differ from the new
default locations (in c:\Program Files).
vii. Ensure that the folders did not get the Read-only attribute set
during the copy
viii. It is critical that the MySQL service is off on both servers
during the copy
ix. Turn off / Shutdown Windows on the old server (needed for
the next step)
12) To avoid changing the TPP sync server configuration setting on all meters, we
recommend changing the new server IP address and hostname to match the old
server. This is also a convenience for all of the TPP web client users.
13) Start the MySQL and then the Apache Tomcat services on the new server. This
may take time to upgrade to the 5.0 schema. It could be hours for a large
database.
14) Test a web client login (as previously done), but using a login that was valid on
the old server.
15) Test meter sync:
a. On the internal company network
b. On the internet to confirm the firewall, routing, and TPP Secure
Sync™ certificates still work for meters out of the office.
16) Inform meter and web users of the upgraded server being back up with the same
IP Address and hostname. Web users may have to install a new login-page
certificate depending on the previous decisions made for hostnames and IP
Addresses. Inform users that their thick clients (TPP 4.8 desktop application)
has been replaced by the TPP Web Client. Give them the URL and ask them to
make a favorite (bookmark) for it.
17) Work with IT to uninstall the JDSU TPP 4.8 Client (the thick client) from all
applicable PCs. Some thick client users may have use the Applet launched
thick client, so will not need to uninstall.
