1) Updated Symposium Agent 2.0 to 2.3 upgrade procedure

The procedures stated in the Symposium Agent 2.3 Installation Guide, Chapter 3 Section B

“Upgrade Instructions”, Pages 51 to 65 have been found to be difficult to follow.

The following procedure is recommended for Symposium Agent 2.0 to 2.3 upgrades:

•1.1 Upgrade overview

•1.2 Backup Symposium Agent 2.0 database

•1.3 Upgrade Symposium Agent 2.0 Sybase 11.5 database to Sybase 12

•1.4 Configure Sybase 12 database

•1.5 Upgrade to Symposium Agent 2.3

•1.6 Configure Microsoft Transaction Server

•1.7 Upgrading SA Symposium Agent Clients 2.3

1.1 Upgrade overview

The upgrade from Symposium Agent 2.0 to 2.3 involves upgrading of the Server software,

followed by upgrading of the clients.

The procedure for upgrading the server software from Symposium Agent 2.0 to 2.3 allows for the

database to be backed up and restored.

Symposium Agent 2.0 uses Sybase 11.5, whereas Symposium Agent 2.3 uses Sybase 12 so the

sequence of the procedure should be closely followed.

1.2 Backup Symposium Agent 2.0 database

Backup Sybase Database.

The Sybase database consists of two separate databases. The master database which holds

information about the database itself and any other databases. And the sar2 database which holds

all the Symposium Agent specific information.

In order to ensure that the complete Sybase environment can be recreated both the databases need

to be backed up before you upgrade Sybase.

Note: The backups that are taken at this point will only be valid for a Sybase 11.5 installation. So

if it becomes necessary to do a restore you will have to restore Sybase 11.5 before you will be

allowed to restore the databases. It should also be noted that Sybase has some over 100 pages of

documentation outlining backup and recovery procedures and the information that is contained

here is primarily aimed at a user that is familiar with backup/recovery procedures.

Backup Symposium Agent Database

Before you backup the database you should:

•Ensure that the relevant Sybase services are running.

•Ensure that there are no users connected to the database.

Once the above has been checked you will be ready to:

Page 2 of 28

•Backup the Sybase master database.

•Backup the Sybase Symposium Agent database (sar2).

Ensure Sybase Services are running.

In order to perform a backup in Sybase you will need to have both:

•“Sybase SQLServer_<computername>” and

•“Sybase BCKServer_<computername> running.

These can be checked using Control Panel – Services. If they are not running then start them.

Ensure that there are no users connected.

To ensure that there are no users connected to the database, start up a command prompt and

connect to the Sybase database.

You now need to open an isql window (connect to the database). The following command will

connect you to the Sybase database as the sa user. This user has the correct privileges to perform

a backup (dump) of the database.

From the command prompt type: isql –Usa –P followed by a carriage return (<CR>). This

should present you with the isql 1> prompt.

Once connected type sp_who followed by <CR> and then type go followed by <CR>, this

should show you something like this. But basically it will tell you who is currently connected to

the DB.

Page 3 of 28

The only user shown as running in the above example is “sa” which is of course the user that we

have logged in as, so that is fine.

Backup the master database.

It is safe at this point to backup the master database.

Type dump database master to “file_name” <CR> followed by go <CR>.

file_name being the name of the dump file that you will create.

Page 4 of 28

This should take approximately one minute.

Backup the sar2 database.

You are now ready to backup the Symposium Agent database, this is known as sar2 within

Sybase. So you would type the following command:

dump database sar2 to “file_name” <CR> followed by go <CR>. file_name being

the name of the dump file that you will create.

This may take some time, and will depend on the quantity of data that is in the database.

As a guideline, it takes the dump command about 10 minutes to write a 50Mb file.

Once this dump has completed you can exit the isql window by typing exit <CR>

1.3 Upgrade Symposium Agent 2.0 Sybase 11.5 database to Sybase 12

Run the pre-upgrade script

Run the Pre-upgrade script

The upgrade script will create a sybsystemdb Database and increase the size of sybsystemprocs

database.

In version 12.0, all servers must have a sybsystemdb database. Version 12.0 uses this database for

tracking transactions and during recovery.

The minimum size for sybsystemprocs is 80MB. If your sybsystemprocs is smaller than 80MB

the upgrade script will increase the size of this database.

The Sybase isql tool will be used to run the upgrade script to create a new sybsystemdb database

and increase the size of sybsystemprocs.

Before you run the isql command, you may need to edit the upgrade.sql file to reference the

default location for your Sybase database files. If the default drive is not the "c:\" then you will

need to edit the upgrade.sql file.

Using notepad, open the upgrade.sql file, located under Nortel\server\nndbcfg

Search for physname="c:/Sybase/data"

Replace the "c" in the pathname with the drive where Sybase is installed. For example, if your

Sybase is on the D drive, the above line will look like this physname= "d:/Sybase/data. .."

There are three instances of this line in the file. Update all three lines.

Now run the following command (all on the same line) to execute the upgrade script:

isql-Usa -p -i x:\Nortel\server\nndbcfg\upgrade.sql-o

x: \Nortel\server\nndbcfg\up grade. out

Note: X is the drive on which you have installed your Symposium Agent server files.

Stop the SQL services

From the services control panel applet stop the SQL services. i.e. Sybase SQLSERVER-

Run Sybase ASE 12.0 installation

From the SA Server CD-ROM, run the Symposium Agent Software installation menu program,

"nnsamenu.exe", and click on the "Install database files" option. You will be prompted for a drive

and folder in which to install the new database files. The drive should have at least 500MB of free

space. Then, a series of batch files will be started that copy the Sybase ASE v12.0 client and

server files. The server will automatically reboot twice during this process.

To complete the upgrade process and convert your existing database to the 12.0 format, use the

Sybase Server Config program and execute the following ten steps:

1 ) Start the Server Config program from Start Menu->Sybase->Server Config

Page 6 of 28

2 ) Click Configure Adaptive Server in the Configure Sybase Servers window.

3) In the Existing Servers window, select the Adaptive Server or SOL Server.

4) Click Configure Adaptive Server.

5) Click Continue.

When Sybase detects that the selected database needs to be upgraded, it will prompt you with a

series of dialogs that will walk you through the rest of the database upgrade process.

6) In the Enter the System Administrator Password window, type the Sybase administrator login

name and password.

7) Select continue.

8) If the Adaptive Server is not running, the upgrade program starts it for you.

9) When prompted backup your database and confirm proceeding with the upgrade.

a. If you have not backed-up the existing database, choose "No" in the Upgrade window and use

NNDBCFG tool or use dump database command to make backup copies.

b. If you have made the necessary backups, select "Yes". The installer begins the database

eligibility test to assure that the Pre-Upgrade steps (above) have been completed.

10) Sybase will now complete the upgrade changes to your database.

Restoring Functionality in ASE

The Sybase isql tool will be used to reset SAR2 database options: .

Page 7 of 28

Bring up a DOS-prompt.

Type l!isql-Usa -pIt.

You will be presented with a 1!>1! prompt.

Use the following commands to reset SAR2 database options:

l>sp-dboption sybsystemprocs, 'trunc log on chkpt', true

2>go

1.4 Configure Sybase 12 database

The database administration utility configures the Symposium Agent database schema. During

the upgrade the Sybase script wizard allows you to make selections to upgrade your database

without destroying existing data.

To configure the database:

1) From the Windows Start menu, choose Settings > Control Panel > Symposium Agent Server,

or select the Desktop shortcut SA Server Configuration.

Result: The Symposium Agent Server Administration window appears

2) Click Database Administration

3) If Sybase Adaptive Server is not running, then click Yes at the prompt.

4) Select Database Configuration, and then click OK

Page 8 of 28

Result: The Sybase script wizard starts.

5) Uncheck all options except “Create Stored Procedures” and “Update Database”.

6) In the SA ( Sybase Administrator) account requires a password, then type the password in

section 2. By default the password is empty.

7) In Section 2, type the name of the computer that is running Sybase Adaptive Server. By

default, it was the name that was previously configured. Select this default.

8) In Section 4, type the name of the computer running the Symposium Agent Call Monitor

service. By default, it was the name that was previously configured. Select this default.

9) In you do not want to view the output after the execution of each SQL script, then clear the

View output check box.

Note: If you select this option, then you are prompted to review the results of each executed

script. Deselect this option for a faster installation.

All script output files are saved in the Symposium Agent directory, in the subdirectory

NNDBCfg. By default, this directory is C:\Nortel\Server\NNDBCfg

10) Click OK.

Result: Various dialog boxes are displayed to indicate progress with the updating of the database

to the latest schema as well as the creation of the stored procedures. It will update the Application

Text Strings as well as the English Strings.

Note: During an upgrade, it is normal for error messages to appear on the screen in the

Lang1033.out file. These messages are caused by inserting duplicate language text strings, and

are informational only.

1.5 Upgrade Symposium Agent 2.3 Server software

Before upgrading the Symposium Agent Server to 2.3 ensure that all other applications are

closed. Stop the SQL service (for example, SQLSERVER_<COMPUTERNAME>).

Shutdown the following two services on the services applet in the Control Panel:

•Nortel SA Call Monitor

•Nortel SA Watchdog

Insert the Symposium Agent Rel 2.3 CD-ROM into the CD-ROM drive. If the Symposium

Agent install menu does not start automatically choose Start > Run and type d:\nnsamenu.exe,

where d: is the letter of the CD-ROM drive, and then click OK.

If you have an older version of Symposium Agent installed, the Installer detects it and

automatically removes the old software after prompting the user. If you answer “No” to

automatically remove the older version, the installer exits without installing the new system.

Once all previous versions of Symposium Agent Server have been removed from the server, the

Install Wizard walks you through the Symposium Agent 2.3 Server installation. For this process

please refer to “To install the server software” section on page 32 of the SA 2.3 Installation

Guide.

Upgrade Note: If SA Web Admin fails to start after an upgrade.

The older versions of Symposium Agent used “C:\Nortel” as the default installation path for the

IIS components. SA 2.3.0.4 uses “C:\Nortel\Server” as the default installation path.

If after an upgrade you attempt to go to http://servername/saadmin in Internet Explorer and get

the “Cannot find page” error message then follow these instructions to get around this issue.

1) Go to START>PROGRAMS>Windows NT 4.0 Option Pack>Internet Information Server>

Internet Service Manager

2) Under Default Web Site, SAAdmin and SAWebApp should indicate ERROR

3) Right click SAAdmin and select properties

4) On the Virtual Directory Tab, modify the Local Path to the appropriate path

(in this case, it changed from c:Nortel to c:Nortel\Server\SAAdmin)

5) Right click SAWebApp and select properties.

6) On the Virtual Directory Tab, modify the Local Path to the appropriate path

(in this case, it changed from c:Nortel to c:Nortel\Server\ SAWebApp)
