memory utilization, server status, and more

11
Failover Manager
Automatically detect failures
• Monitors database health - detects failures
and takes action
• Automatically fails over to the most current
standby, reconfigures others
• Reconfigures load balancers on failover -
integrates with pgPool and others
• Avoids “split brain” scenarios - Prevents two
nodes from thinking that each is primary

12
Backup and Recovery Tool
Safeguard business data and ensure trouble-free recovery
• Centralized repository for all backup data
• Configures retention policies for
multiple backups
• Restores the database from system-wide
repository when disaster strikes

EDB Migration Portal
Oracle DDL Assessment, Transformation and Migration
● Portal Launch: July 2018
● Assesses Oracle 11G/12C
● DDL assessment for EPAS
● 98 automatic syntactical conversion rules
● 13 object types (Synonyms, DB Links, Types
and Type Bodies, Sequences, Tables,
Constraints, Indexes, Views, Materialized
Views, Triggers, Functions, Procedures,
Packages)
● 11.3M DDL objects assessed since 2018
● 92% of Oracle DDL objects are EDB Postgres
Advanced Server compatible
● Free to use for assessments and migrations

14
● The best database, without HA, monitoring or management has limited value
● Management at scale requires exception based approaches
● Databases without integration tools are data silos
● Rapid digital transformation requires migration tools
Why database and Tools?

20
https://www.enterprisedb.com/postgres-tutorials/what-parallel-vacuum-postgresql-13
Vacuum Improvements
● Performance for parallel vacuum of indexes
○ Vacuum performance after executing 50 million
in-place updates - 4X faster in multi process benchmark
● Auto Vacuum for append-only transactions
○ Recalculates statistics!
○ Important for IOT tables
Parallel vacuum of indexes and vacuum for append-only tables

21
● Pg_catcheck: tool for diagnosing system catalog corruption
● Find it https://github.com/EnterpriseDB/pg_catcheck
● New capability: check if the initial ﬁle is available for every relation (table)
● Address ‘could not open ﬁle issue’
New capabilities for pg_catcheck

22
● New option --select-from-relations
.
● This option won't tell you the reason why you are getting such errors.
● Works for table, TOAST table, and materialized view in the database.
● This option still doesn't help with indexes, or relation segments other than the first file
● >>> The relation is accessible <<< “Could not open file”.
● Supports EDB Postgres Advanced Server and PostgreSQL.
● Example:
rushabh@rushabh:pg_catcheck$ ./pg_catcheck edb --select-from-relations
notice: unable to query relation "public"."emp": ERROR: could not open file
"base/16198/16394": Permission denied
notice: unable to query relation "public"."jobhist": ERROR: could not open
file "base/16198/16405": No such file or directory
progress: done (2 inconsistencies, 0 warnings, 0 errors)
pg_catcheck: find “could not open file xxx”

23
EDB Advanced Server: DBA productivity
Feature Benefit
Automatic LIST partitioning
● Each partition is defined by list of values that can be stored in the
partition. (e.g UK, US).
● When row inserted with values that don't belong to any partition
(e.g. FR for France), EPAS will create a new partition to store all
rows with that value of that partition key
● Customer doesn’t need to know all partition keys
when defining the table
● Removes risk of errors when a row is inserted that
would not fit in the table
● Eliminates manual labor of creating each and
every partition individually
Automatic HASH partitioning
● Partitions are defined by hash values, which will distribute data
evenly across partitions.
● Users specify the number of partitions, which are to be created
automatically with insert data requests.
Automatic partitioning methods (LIST, RANGE and HASH) can be combined
with partitions and subpartitions

24
EDB Advanced Server: DBA productivity: examples
Use case Example
Create a table with automatic List
partitioning. In this example, a
partition is automatically created
for the entry with 'NLD'.
CREATE TABLE orders (id INT, country_code VARCHAR(5))
PARTITION BY LIST (country_code) AUTOMATIC
(partition p1 values ('IND'), partition p2 values ('USA'));
INSERT INTO orders VALUES(1, 'NLD')
Automatically create a table with 4
partitions. Values will be randomly
spread across the 4 deﬁned
partitions.
CREATE TABLE hash_tab (col1 NUMBER< col2 NUMBER)
PARTITION BY HASH (col1, col2)
PARTITIONS 4 STORE IN (tbs1, tbs2, tbs3, tbs4);

25
EDB Advanced Server: DBA productivity
Feature Beneﬁt
EDB*Loader (bulk database loading utility) no longer aborts on
duplicate rows.
Duplicate records are output to the 'bad' ﬁle.
Enables developers and DBAs to use this utility to test applications faster
by avoiding interruptions from duplicate records.
edb_log_every_bulk_value creates one Audit log entry on the bulk
execution instead of one entry for every processed row.
The log entry lists the number of rows processed and appears in the
audit and server log.
Enhanced information on bulk executions

26
EDB Advanced Server: Oracle compatibility
Feature Benefit
Enhancements to Data Definition Language
● CREATE TABLE and ALTER TABLE can now specify a custom index with "USING INDEX”
● CREATE TABLE and CREATE INDEX can now be created with a PARALLEL/NOPARALLEL option
Commands expedite migration from Oracle
Enhancements to EDB Structured Procedural Language
● Procedures are enhanced to allow specifying DEFINE_COLUMN_LONG, COLUMN_VALUE_LONG
and LAST_ERROR_POSITION
● Compound triggers can now be created with WHEN clause, NEW/OLD variables and STATEMENT
level triggering events.
● EDB-SPL allows for forward declaration inside package body for Function/procedure
Migrated applications using these stored
procedures don’t need to be rewritten
Aggregate statistical functions & time stamp
● STATS_MODE: Returns the value with the highest frequency
● MEDIAN: aggregate function
● TO_TIMESTAMP_TZ: Converts character type to a value of TIMESTAMP WITH TIME ZONE data type
Allows customers to run native Oracle statistical
functions and type conversion functions without
needing to require their application code
UTL_HTTP supports END_OF_BODY exception. This package makes (HTTP) callouts from SQL or PL/SQL. Reduces complexity by making it easier to write
applications that need to parse data (e.g. find data
strings) from the internet

27
EDB Advanced Server: Security
Feature Beneﬁt
DBMS_CRYPTO supports AES192 and AES256 encryption algorithms Enables customers to use native Oracle syntax to encrypt data at
rest (database encryption) and meet security requirements
Enhanced EDB Audit to log SET commands Creates a trail when auditing is running with lower edb_audit
settings in a SUPERUSER session

Feature Benefit
Graphical Query Plan Analyzer Analyze query plans in the Graphical Explain tab in the Query Tool. It shows the time spent by each plan
node and highlights misestimations between actual and plan. It also shows statistics for each plan node
and each table
Schema Diff Tool Identifies schema differences between test, stage and production environments.
SNMP V3 Support Provides increased security by using SNMP version 3 while sending the alert traps.
Enhanced Performance Diagnostics Users can now see the number of active sessions at a sample time, and whether a session is waiting for an
event or utilizing the CPU at a particular sample time. This provides a clear picture of what percentage of
time a session has been waiting for an event.
Enhanced integration of Backup and
Recovery Tool and Failover Manager
More efficient management and monitoring of BART and EFM via the PEM console
Web Content Accessibility Guidelines
(WCAG) 2.0 AA certification
Meeting this guideline is important to many prospects, especially to the public sector and large
enterprises
Ability to monitor AWS RDS Postgres
and Postgres on AWS EC2
Enables customers to manage their PostgreSQL estate, from one GUI, even in cloud/hybrid environments

EFM/BART: High Availability and Backup/Recovery
Feature Benefit
Failover Manager stores database password with stronger encryption using
SHA-512
Allows customers to use Failover Manager in environments requiring strong
password encryption algorithms
Failover Manager encrypts messages between agents Allows customers to use Failover Manager in environments which require message
encryption
Failover Manager: Standby servers don’t have to be stopped during election
process when new primary is chosen
Speeds up promotion process, which is very relevant in environments where
failover times must be short to meet high SLA requirements
BART: FIPS 140-2 (Federal Information Processing Standards) configuration
options: disable checksum verification and configure the bart_socket_name
Enables customers to run in more secure environments by allowing them to
disable MD5 checksums
