§ SAP creates an ASE AMI – preinstalled
§ A pre-installed, preconfigured
ASE
§ A block device mapping that
specifies the volumes to
attach to the install when
it’s launched
§ Customers deploy licenses obtained from SAP
§ An ASE instance can be launched
§ Only one image created; users need to follow the
user guide to make configuration change. An
auto-configure tool would be available later.

Using ASE on AWS
§ Create an account on
Amazon AWS
§ Obtain license from SAP;
generate a license key
§ Select ASE AMI on Amazon
AWS
§ Launch an instance from the
AMI; deploy the license
key
§ Support
§ Contact SAP for support
questions
§ For patches, deploy
those directly onto
the instance; SAP
will only release
new AMI at the level
of major or minor
releases

Provision a Database
• (A) Create, using resource files, a new Adaptive Server, with default or
user-specified values for key configuration attributes
• srvbuildres [-s sybase_dir] [-I interfaces_file] [-r resource_file]
• -s sybase_dir specifies the value to use for the SYBASE environment
variable.
• -I interfaces_file specifies the name and location of the interfaces file to
search
• -r resource_file executes the specified resource file
• (B) Load data into the newly created database

Virtualized Resource ManagementTM in
SAP ASE System
Bind an execution class for a login or application:
• Create an engine group called DS_GROUP :
- sp_addengine 0, DS_GROUP
sp_addengine 1, DS_GROUP
• Create a user-defined execution class : -
sp_addexecclass DS, LOW, 0,
DS_GROUP
• Bind the manager login mgr1 to DS
execution class
sp_bindexeclass mgr1, LG, NULL, DS
•
•Add Compute power to a login:
• sp_addengine 3, DS_GROUP
•
•Reduce compute power to a login:
• sp_dropengine 2, DS_GROUP

STOPSTOP
Managing Resource Limits for
Clients
• Manage resource usage for a query, batch or transaction
• Limit specified in I/O cost, elapsed time, number of rows returned, or
tempdb space usage
• Pre-execution or runtime
• Configurable “action” for violation
• Configurable date and time option

Defining Resource Limits
•Limit’s defined using:
• Login Name (optional)
• Application Name (optional)
• Time range for limit (optional).
Examples:
• Business_Hours:
• Monday-Friday
8:00-18:00
• Post_business_hours:
• Monday-Friday
18:00-24:00
• Type of resource to limit and
the actual limit
• I/O cost
• # of rows returned
• Time of enforcement
• Pre-Execution and
runtime limits
supported for i/o limits
• Other limits only
enforced at runtime
• Action to take when limit is
exceeded
• Warning (Error log & App)
• Abort query batch
• Abort transaction
• Kill the session
• Limit Scope
• Query, Batch or
Transaction

Security: Database Encryption
•Full DatabaseEncryption
• Secure: all user data,
index and log in
database will be
encrypted with
standard
cryptographic
algorithm AES
• Transparent: there is
no difference
between encrypted
database and
normal database
from application
point of view.
Database
Column Level
Encryption
•Simple extension to the
well understood concept
of column properties in an
RDBMS
•Allows different data
elements to be encrypted
using different keys –
providing granularity of
access
•Balances complexity, risk,
and performance

Security: Granular Permission Controls
•Construct site-specific roles with privileges to match site
job requirements
•
• Restrict DBOs and SAs from accessing user data if
needed
•
• Allow customers to revoke permissions from out-of-box
system defined roles.
Implicit permission vested in sa_role/sso_role/
dbo can be revoked
By default, sa_role would not have
permissions on objects not owned by dbo

Security: Predicated Privileges
•Flexible low-level access controls
• Access to data granted subject to
conditions evaluated at the time of
accessing the data
• Conditionally activate roles during
login based on evaluation of a predicate.
• Sensitive data protected by access
tag reveals whether a row and column
can be released to a given security
domain.

•Zero data loss (in HA configuration)
•Transparent client failover
•Planned and unplanned failover support
•Soft quiesce for planned failovers without
stopping applications
•Zero downtime upgrades, including
major releases
•Automated fault detection and handling
•Ability to fully leverage companion
assets for reporting in a enforced
read-only mode that does not require
user administration

DB Elasticity: Automatic Size
Expansion
• For automatic database expansion, a
service could be built using the
following support from ASE:
• Use sp_dbextend to install
automatic database
expansion procedures on
database/segment pairs
and devices
• Define the site-specific
policies for individual
segments and devices
• Establish the thresholds for
• Example of automatic database expansion service:
• Create the database: create database pubs2 on
pubs2_data = "10m" log on pubs2_log =
"5m“
• Set the ‘growby’ and ‘maxsize’ policies of the data
device: exec sp_dbextend 'set',
'device', pubs2_data, '10m', '512m‘
• Set the ‘growby’ and ‘maxsize’ policies of the log
device: exec sp_dbextend 'set', 'database',
pubs2, 'logsegment', '4m', '100m'
• Install the expansion threshold for the default and
log segments: exec sp_dbextend 'set',
'threshold', pubs2, 'default', '4m'
