2 New Features in Sentinel 6.1

This section explains the new features available in Sentinel 6.1.

Section 2.1, “New Features in Sentinel 6.1.1.0,” on page 2

Section 2.2, “New Features in Sentinel 6.1 Hotfix 1,” on page 2

2.1 New Features in Sentinel 6.1.1.0

Sentinel 6.1.1.0 is a maintenance release for Sentinel 6.1. In addition to bug fixes, it contains

enhanced Advisor feature.

2.1.1 Advisor update

The 6.1.1.0 service pack installer deletes the old Advisor data, which has erroneous Advisor

mappings, and enables you to start downloading the new Advisor data.

With the Sentinel 6.1.1.0 release, the existing Advisor download URL will be redirected to a server

containing the new Advisor data. In order to continue to receive automatic updates of the latest

Advisor data, you need to upgrade to Sentinel 6.1.1.0.

2.2 New Features in Sentinel 6.1 Hotfix 1

This section lists the features available in Sentinel 6.1 Hotfix 1 Release.

AUDIT_RECORD Table Partitioning - The AUDIT_RECORD table is configured for

partitioning and archiving for better table management.

Customizing Data and Time Format in Sentinel Control Center - This feature gives the ability

to customize the date/time format that is displayed in event tables in SCC. These event tables

are the ones seen in Active Views, Historical Event Query, Offline Query, etc. By default, the

date/time format will be based on the locale of the machine running SCC; however, the user

can override this default by adding a property to the SentinelPreferences.properties file found

in $ESEC_HOME/config.

3 Prerequisites

The prerequisites depend on the Sentinel system version and platform. Read each section below

carefully to determine whether the steps apply to your environment.

3.1 Back Up Sentinel System

This prerequisite applies to all Sentinel systems, regardless of version or platform.

It is highly recommended that a complete backup be made of the machines on which you are

installing the service pack, including the Sentinel database. If this is not possible, then at a minimum

a backup of the contents of the ESEC_HOME directory should be made. This will help protect your

system against unexpected installation errors.

Novell Sentinel™ 6.1.1.0 3

3.2 Back Up AUDIT_RECORD Table

This prerequisite is not necessary if you have already applied Sentinel 6.1 Hotfix 1 (6.1.0.1). It is

necessary if Hotfix 1 has not been applied yet.

Starting with Sentinel 6.1 Hotfix 1, the AUDIT_RECORD table, which contains internal audit

events for the Sentinel system, is configured for partitioning and archiving for better table

management. Because the existing table is not partitioned or archived, the PatchDB script may fail if

the AUDIT_RECORD table is too large relative to the amount of temporary tablespace available.

There are two approaches to ensure the PatchDB script runs successfully, depending on whether it is

critical to your organization to preserve the data in the AUDIT_RECORD table.

If the AUDIT_RECORD data is not important, truncate the AUDIT_RECORD table using the

following SQL command:

TRUNCATE TABLE AUDIT_RECORD

If the AUDIT_RECORD data is important and needs to be preserved, add more space to the

temporary tablespace. The amount of space to be added depends on your environment; consult

your Database Administrator (DBA) for adequate settings.

4 Installation

The instructions provided in this section are for installing Sentinel 6.1.1.0 Service Pack only. This

Service Pack can be run against an existing installation of Sentinel™ 6.1.

Follow the below listed instructions to install the Service Pack for software and database:

1Login to any machine which has Sentinel installed.

On Linux/Solaris, log in as root.

On Windows Vista, log in as any user unless User Access Control is disabled. If User

Access Control is disabled, you must log in as an Administrator.

On other (non-Vista) Windows systems, log in as an Administrator.

2Verify that the environment variables for Sentinel are set by running one of the following

commands:

On Linux/Solaris, echo $ESEC_HOME

On Windows, echo %ESEC_HOME%

3Extract the Service Pack zip file.

4Close all Sentinel applications running on this machine, including:

Sentinel Control Center

Sentinel Collector Builder

Sentinel Data Manager

Solution Designer

5Shut down the Sentinel services running on this machine:

On Windows, use Windows Service Manager to stop the “Sentinel” services.

On Linux/Solaris, run $ESEC_HOME/bin/sentinel.sh stop

4Novell Sentinel™ 6.1.1.0

6Open a command prompt. For most Windows systems and Linux/Solaris, you can use any

method to open the prompt. For Windows Vista, you must open the command prompt as an

administrator using the following instructions.

6a Go to Start > All Programs > Accessories.

6b Right-click Command Prompt and select Run as administrator.

6c If User Access Control is enabled and you are logged in as a user with administrator

privileges, a User Access Control window appears to notify you that “

Windows needs

your permission to continue

”.

6d Click Continue. If you are logged in as a user without administrative privileges, you will

be prompted to authenticate as an administrative user.

7On the command line, return to the extracted Service Pack top level directory and run the

service_pack script to start the Service Pack installer:

On Windows: .\service_pack.bat

On Unix: ./service_pack.sh

8Press the <ENTER> key when prompted to start the Service Pack installation procedure.

9After the installation completes, log out and log back in to apply environmental variable

changes.

10 Repeat the above steps on every machine with Sentinel software installed. This is required for

all machines with any Sentinel software, including both Sentinel server and client software.

11 Restart the Sentinel services on all machines:

On Windows, use Windows Service Manager to start the “Sentinel” services.

On *NIX, run

$ESEC_HOME/bin/sentinel.sh start

12 This Service Pack also contains a mandatory patch for the Sentinel Database. Apply the

database patch by performing the appropriate steps in the section below for the database

platform you are using.

5 Sentinel Database Patch Installation

In addition to patching the Sentinel components, you must run a script to patch the database. The

instructions are different depending on which database you have.

Section 5.1, “Sentinel Database Patch Installation on Oracle,” on page 4

Section 5.2, “Sentinel Database Patch Installation on SQL Server,” on page 6

5.1 Sentinel Database Patch Installation on Oracle

There are several prerequisites for applying the Oracle database patch. The machine and account

from which the database patch is run must meet the following requirements:

User has the Oracle client application sqlplus in its PATH.

User has the environment variable ORACLE_HOME set to the directory where the Oracle

software is installed.

User must be a member of the Oracle "dba" group.

User has the Java 1.5 executable java in its PATH.

Novell Sentinel™ 6.1.1.0 5

TIP: The easiest way to apply the patch is to run the PatchDB script directly on the database server

machine after logging in as a user that meets the requirements above. However, in some

environments, local policies prohibit this (for example, you cannot install Java on the database

server).In this situation, the script can be run from any other machine that meets the requirements

stated above.

Any Sentinel 6.1 machine will already have the necessary version of Java, but the default Java

installation done by Sentinel does not allow the oracle user access to the

$ESEC_HOME/jre

directory. You can add the Oracle user to the esec group (for example, groupmod –A oracle esec),

temporarily modify the permissions on the directory (for example, chown –R oracle

$ESEC_HOME/jre), or install a second instance of Java.

If using a non-Sentinel machine, the Java version and PATH variable settings can be verified by

running the

java -version

command from a command line:

If necessary, the PATH environment variable can be updated to include the java installation

directory, for example:

export PATH=/opt/novell/sentinel6/jre/bin:$PATH

If Java is not installed on the non-Sentinel machine, the correct Java version [Java Runtime

Environment (JRE) 5.0] can be downloaded from the Sun Web site (http://java.sun.com/javase/

downloads/index_jdk5.jsp).

After the prerequisites are met, use the following instructions to apply the database patch.

1Log in to the database server or another machine with connectivity to the Sentinel Database as

a user who meets the above installation prerequisites.

2Verify that your machine meets the Java prerequisites.

3Extract the Service Pack zip file.

4On the command line, go into the Service Pack top level directory that was just extracted.

5Change directories to the following directory under extracted top level directory:



db_patch/bin

6Enter the

./PatchDb.sh

command.

7Follow the prompts and enter the following information:

Hostname or static IP address of the Oracle Sentinel Database that you want to patch.

Port number of the Oracle Sentinel Database that you want to patch.

Database net service name.

Database service name of the Oracle Sentinel Database that you want to patch.

esecdba user password.

After you press Enter the final time, the script verifies the entered information and begins the

database patch.

8After the script is done applying the patch, check for any errors. If there are no errors, you are

done with the Sentinel Database patch. If there are errors, resolve the errors and re-run the

PatchDb utility.

6Novell Sentinel™ 6.1.1.0

9Restart the Sentinel services on all machines:

On Windows, use Windows Service Manager to start the “Sentinel” services.

On *NIX, run

$ESEC_HOME/bin/sentinel.sh start

5.2 Sentinel Database Patch Installation on SQL Server

The following steps must be performed on the machine with a Microsoft SQL Server database to

prepare the database for 6.1.1.0. There is one main patch script for SQL Server (PatchDb.bat).

There are several prerequisites for applying the SQL Server patch.

The patch must be copied to the machine that is running the Sentinel database.

The patch must be run by using the Sentinel Database User credentials, or esecdba if you are

using SQL Authentication.

Use the appropriate instructions depending on whether the database uses Windows authentication or

SQL Server authentication.

“Installing Database Patch with Windows Authentication” on page 6

“Installing Database Patch with SQL Server Authentication” on page 7

5.2.1 Installing Database Patch with Windows Authentication

To install the database patch with Windows authentication, you need the credentials for the Sentinel

Database User.

1Log into the database machine as the Windows Domain user who is the Sentinel Database User.

2Shut down the Sentinel Server processes (if this has not already been done).

3Extract the Service Pack zip file (if this has not already been done).

4Open a command prompt.

5Change directories to the following directory under the extracted Service Pack directory:



db_patch\bin

6Enter the

.\PatchDb.bat

command.

7Follow the prompts and enter the following information:

Hostname or static IP address of the SQL Server Sentinel Database machine.

SQL Server Database instance name, if any.

Port number of the SQL Server database.

Name of the SQL Server database to patch (ESEC by default).

1 for the Windows Authentication option.

After you press Enter the final time, the script verifies the entered information and

proceeds if authentication is successful.

8After the script has done applying the patch, check for any errors. If there are errors, resolve the

errors and re-run the PatchDb utility.

9After the patch runs with no errors, “Sentinel” services should be restarted.

Novell Sentinel™ 6.1.1.0 7

5.2.2 Installing Database Patch with SQL Server Authentication

To install the database patch with SQL Server authentication, you need the credentials for the

Sentinel Database User.

1Log into the database machine as the Windows Domain user who is the Sentinel Database User.

2Shut down the Sentinel Server processes (if this has not already been done).

3Extract the Service Pack zip file (if this has not already been done).

4Open a command prompt.

5Change directories to the following directory under the extracted directory:



db_patch\bin

6Enter the

.\PatchDb.bat

command.

7Follow the prompts and enter the following information:

Hostname or static IP address of the SQL Server Sentinel Database machine.

SQL Server Database instance name, if any.

Port number of the SQL Server database.

Name of the SQL Server database to patch (ESEC by default).

2 for the SQL Authentication option.

esecdba user password.

After you press Enter the final time, the script verifies the entered information and proceeds if

authentication is successful.

8After the script is done applying the patch, check for any errors. If there are errors, resolve the

errors and re-run the PatchDb utility.

9After the patch runs with no errors, “Sentinel” services should be restarted.

6 Post-Installation

After running the installer, some additional updates may be necessary.

By default, the Sentinel Control Center (SCC) uses a date and time format that is appropriate for the

locale for which the Sentinel Control Center is configured, but that default can be overridden. For

formatting details on customizing the date and time format in event field in Sentinel Control Center,

see the Java Web site (http://java.sun.com/j2se/1.5.0/docs/api/java/text/SimpleDateFormat.html).

1Edit the

SentinelPreferences.properties

file.

On Windows:

%ESEC_HOME%\config\SentinelPreferences.properties

On *NIX:

$ESEC_HOME/config/SentinelPreferences.properties

2Uncomment the following line and modify to customize date and time format for Sentinel

Control Center event date/time fields.
