Note:

Sun Fire X4170 M2 Oracle Database Servers ship from the factory with 96 GB of memory with 12 of the 18 DIMM slots populated with 8 GB DIMMs. The optional X2-2 Memory Expansion Kit can be used to populate the remaining 6 empty slots with 16 GB DIMMs to bring the total memory to 192 GB (12 x 8 GB and 6 x 16 GB), or replace the existing 8 GB DIMMs with 16 GB DIMMs and add memory to bring the total memory to 288 GB (18 x 16 GB).

The memory expansion kit is primarily for consolidation workloads where many databases are run on each database server. In this scenario, the CPU usage is often low while the memory usage is very high.

However, there is a downside to populating all the memory slots as the frequency of the memory DIMMs drop to 800 MHz from 1333 MHz. The performance effect of the slower memory appears as increased CPU utilization. The average measured increase in CPU utilization is typically between 5% and 10%. The increase varies greatly by workload. In test workloads, several workloads had almost zero increase, while one workload had as high as a 20% increase.

New Features for Oracle Exadata System Software Release 19.x

New Features for Oracle Exadata System Software Release 19.x

What's New in Oracle Exadata Database Machine 19.3.0

Persistent Memory Data Accelerator:
Oracle Exadata Storage Server can now use a Persistent Memory (PMEM) Cache in front of Flash Cache. Known as Persistent Memory Data Accelerator, the PMEM cache uses Intel Optane™ DC Persistent Memory Modules (DCPMM). The Database Server uses remote direct memory access (RDMA) to enable 10x faster access latency to remote persistent memory.

Since the persistent memory is used as a shared cache, caching capacity effectively increases by 10x compared to directly using the persistent memory modules as expensive storage. This arrangement makes it cost effective to apply the benefits of persistent memory to multi-terabyte databases.

Minimum requirements:
Oracle Exadata System Software release 19.3.0
Oracle Database 19c
Oracle Exadata Storage Server X8M-2

Persistent Memory Commit Accelerator
Consistent low latency for redo log writes is critical for OLTP database performance, since transactions are committed only when redo logs are persisted. Furthermore, slow redo log persistence affects critical database algorithms. With the persistent memory commit accelerator, Oracle Database 19c uses Remote Direct Memory Access (RDMA) to write redo records in persistent memory on multiple storage servers. By using RDMA, the redo log writes are up to 8x faster, and excellent resilience is provided because the redo log is persisted on multiple storage servers.

On each storage server, the persistent memory area contains only the recently written log records and persistent memory space is not required for the entire redo log. Therefore, hundreds of databases can share the persistent memory area, enabling consolidation with consistent performance.

Minimum requirements:
Oracle Exadata System Software release 19.3.0
Oracle Database 19c
Oracle Exadata Storage Server X8M-2

Support for Oracle Exadata X8M Systems:
A new class of Database and Storage Server, designated X8M, are designed to utilize RDMA over Converged Ethernet. Known as RoCE (pronounced rocky), RDMA over Converged Ethernet is the combination of using the existing Remote Direct Memory Access (RDMA) networking verbs, in association with the InfiniBand™ Trade Association (IBTA) standards based extensions for Converged Ethernet to enable high speed fabrics over Ethernet layer 2 and 3 networks. RoCE shares a common API infrastructure with InfiniBand, differing only at the physical and link layers. All existing Oracle Exadata Database Machine high-performance architecture and tuning is compatible with the new network.

Oracle Exadata Database Machine X8M-2 and X8M-8 Database Servers utilize 100Gb/sec RDMA Network cards, which enables higher IO performance, and, when used in conjunction with Oracle Exadata Database Machine X8M-2 Storage Servers with persistent memory acceleration, experience up to 10x lower latency for RDMA reads. All Oracle Exadata Database Machine X8M-2 Storage Servers use the 100Gb/sec RDMA network cards, however the Extended Storage Server (XT) does not receive the persistent memory acceleration. High Capacity and Extreme Flash Storage Servers for the X8M generation receive 1.5 TB of persistent memory per server.

The Oracle Database and Oracle Grid Infrastructure software installations on Oracle Exadata Database Machine X8M database servers must meet the minimum release requirements listed in Oracle Linux Kernel to Unbreakable Enterprise Kernel 5 and Oracle Linux Distribution Upgraded to Oracle Linux 7.7.

Oracle Exadata Database Machine X8M servers must use Oracle Exadata System Software release 19.3.0 or later.

Instant Failure Detection for X8M Systems :

Exadata uses heartbeats to detect the failure of various components. Server failure detection normally requires many missed heartbeats to avoid a false failure diagnosis. Exadata uses remote direct memory access (RDMA) on the RoCE network to quickly confirm server failures. Since RDMA uses hardware, the remote ports respond quickly even when the server is heavily loaded.

Instant failure detection is a unique technology that works transparently and enables incredible availability for OLTP applications.

KVM is the virtualization technology used with Oracle Exadata Database Machine systems configured with RoCE interconnects. KVM provides kernel level hypervisor support, so the host kernel and KVM guest kernel are the same. Oracle Exadata Deployment Assistant (OEDA) is used to create KVM guests and clusters, and a KVM guest uses SR IOV virtual functions for RoCE network connectivity.

Xen is not supported for Oracle Exadata Database Machine systems configured with RoCE interconnects, and KVM is not supported on Oracle Exadata Database Machine systems configured with InfiniBand interconnects.

Faster Encrypted Table Smart Scans
Scans of encrypted tables have been improved by decrypting columns only when needed. Columns in the SELECT set or predicates are the only columns decrypted, not the entire flash cache cacheline. If the first predicate does not return any matches, then the columns for the second predicate are not accessed. This feature has up to 30% faster encrypted smart scans and reduced storage server CPU usage.
For example, consider the following query:
SELECT ename FROM emp
WHERE job LIKE ‘%VP’ AND sal + bonus > 500000

Only the projected columns (ename) and one or more predicated columns are decrypted. The salary in data regions that do not have a VP are not accessed.

Minimum requirements:
Oracle Exadata System Software release 19.3.0

Smart In-Memory Columnar Cache with Row IDs
Oracle Exadata System Software evaluates the predicate in a DML statement to determine the rows of interest. These rows are sent back from the storage servers to the database servers, which then uses the ROWIDs to update the rows. This feature expands this functionality to return ROWIDs for data stored in columnar compression format.

For example, consider the following SQL query:

UPDATE weather_history SET temp = (temp – 32) * (5/9)
WHERE country = 'ENGLAND'

Smart scan is used to find the rows that satisfy country = 'ENGLAND' using ROWID values returned from a previous phase of the command processing.

This feature can improve the performance of DML statements by up to 5x.

Minimum requirements:
Oracle Exadata System Software release 19.3.0
Oracle Database release 18.3.0.0.180717DBRU

Smart In-memory Columnar Cache with Chained Rows
Wide tables, large rows or row migration on update can create chained rows. Smart In-memory Columnar Cache works by creating optimized Single Instruction Multiple Data (SIMD) representation for chained rows when the head and tail pieces fit in the same 1 MB region. This results in up to 3x faster scans for wide tables.

Minimum requirements:
Oracle Exadata System Software release 19.3.0

Fast Smart In-memory Columnar Cache Creation
The run-time analyzer finds the best compression algorithm, reusing the dictionary created in-line during the analysis. This provides faster symbol lookup and insert using the new dictionary data structure. The Single Instruction Multiple Data (SIMD) optimized columnar cache creation reuses data from the first pass scan in the flash cache. The result is much faster reads from the flash cache, with an up to 35% improved speed in columnar cache creation.

This feature applies to Exadata Hybrid Columnar Compression tables only.
Minimum requirements:
Oracle Exadata System Software release 19.3.0

Update a Single SNMP User Definition
This feature adds new syntax to ALTER CELL and ALTER DBSERVER commands to allow SNMP V3 users to be added, altered, and deleted individually instead of configuring all users in one command string. This features makes it easier to change the password for an individual SNMP user.

ALTER CELL {
| SHUTDOWN SERVICES { RS | MS | CELLSRV | ALL } [IGNORE REDUNDANCY]
| RESTART SERVICES { RS | MS | CELLSRV | ALL } [IGNORE REDUNDANCY]
| RESTART BMC
| STARTUP SERVICES { RS | MS | CELLSRV | ALL }
| LED {ON | OFF}
| DONOTSERVICELED {ON | OFF [FORCE]}
| VALIDATE { MAIL | SNMP | CONFIGURATION }
| VALIDATE SYSLOGCONF selector.node
| CONFIGUREBMC
| BBU { DROP FOR REPLACEMENT | REENABLE }
| { snmpuser=((user_clause)[,(user_clause)[,..]]) | snmpuser.name=(user_clause) }
| attribute_name = attribute_value
[, attribute_name = attribute_value]...
}

ALTER DBSERVER {
| SHUTDOWN SERVICES { RS | MS | ALL }
| RESTART SERVICES { RS | MS | ALL }
| RESTART BMC
| STARTUP SERVICES { RS | MS | ALL }
| LED { ON | OFF }
| VALIDATE { MAIL | SNMP | CONFIGURATION }
| VALIDATE SYSLOGCONF facility.priority
| CONFIGUREBMC
| { snmpuser=((user_clause)[,(user_clause)[,..]]) | snmpuser.name=(user_clause) }
| attribute_name = attribute_value
[, attribute_name = attribute_value]...
}

Securing Storage Server Software Processes with Memory Protection Keys
Memory Protection Keys is a hardware feature found in Oracle Exadata Database Machine X7-2 and newer systems. Memory Protection Keys provide a thread local permission control on memory pages without incurring the high cost of Page Table Entry (PTE) modifications and Translation Look-aside Buffer (TLB) flushes.

The Exadata storage server process that performs block IO (cellsrv) and the processes that perform smart scans (celloflsrv) are now enhanced to run with memory protection keys. This feature is enabled out of the box with no tuning needed. Each thread in these processes needs to obtain access to the appropriate memory protection key before it can access the data. Any access to a piece of memory that does not have the correct key traps the process. This enhances the security and robustness of the storage server processes by eliminating a class of potential memory corruptions.

Minimum requirements:
Oracle Exadata System Software release 19.3.0
Oracle Exadata Database Machine X7-2

Default XFS File System for X8M Servers
To further improve the security of Oracle Exadata Database Machine, the new X8M servers will use the XFS file system for bare metal, KVM guests, and storage servers.

New partitions are created for /home, /tmp, /var, and /var/log/audit.

Minimum requirements:

Exadata in the Cloud:

The investment protection that Oracle has ensured through multiple Exadata generations on-premises, has continued with Oracle Database Exadata Cloud Service, and with Oracle Database Exadata Cloud at Customer.
With Exadata Cloud Service, customers can now run Oracle databases in the cloud on Exadata, with the same extreme performance and availability experienced by thousands of organizations deploying Exadata on-premises. Exadata Cloud Service combines the world’s #1 database – Oracle, and the most powerful database platform – Exadata, with all the simplicity and operational flexibility of the public cloud. Oracle databases deployed in the cloud as part of this service include all Oracle Database options and features – such as Oracle Multitenant, In-Memory Database, Real Application Clusters (RAC), Active Data Guard, Partitioning, Advanced Compression, Advanced Security, etc. It also includes all Oracle Enterprise Manager packs.
The underlying design principle of Exadata Cloud Service is that Oracle databases deployed in this Cloud Service are 100% compatible with those deployed on-premises. This means that customers’ applications and data models do not have to change, ensuring a smooth transition to the cloud, and an efficient hybrid cloud strategy. They also do not have to invest in multiple cloud platforms for multiple workloads since Exadata provides a unified platform for all workloads – analytics, data warehousing, OLTP, consolidation, in-memory and mixed-workloads.
Exadata Cloud at Customer takes this investment protection one step further by enabling a cloud-based Oracle Database subscription service available on Oracle Exadata, with all Database options and features, but deployed in the customer data center behind their firewall. Customers enjoy the benefits of agile cloud-based provisioning, while the associated Exadata infrastructure is maintained by Oracle.

Oracle Exadata Full Half Quarter Racks differences

Here are some differences between Full Rack, Half Rack and Quarter Racks
(in Oracle Exadata).

RACK	No. of Cells	No. of Nodes	No. of Cores	No. of Disks	SAS Storage	SATA Storage	No. of InfiniBand Switches
Full Rack	14 Cells	8 Nodes	64	168	100TB	336TB	3
Half Rack	7 Cells	4 Nodes	32	84	50TB	168TB	3
Quarter Rack	3 Cells	2 Nodes	16	36	21TB	72TB	2

I consider the following seven terms and definitions utterly important for folks to know before sitting through an Exadata presentation.

Cell Offload Processing.

Work performed by the Storage Servers that would otherwise have to be executed in the database grid. Includes functionality like Smart Scan, datafile initialization, RMAN offload, Hybrid Columnar Compression (HCC) decompression.

Smart Scan.

Most relevant Cell Offload Processing for improving Data Warehouse / Business Intelligence query performance. Smart Scan is the agent for offloading filtration, projection, Storage Index exploitation and HCC decompression.

Full Scan or Index Fast Full Scan.

The required access method chosen by the query optimizer in order to trigger a Smart Scan.

Direct Path Reads.

Required buffering model for a Smart Scan. The flow of data from a Smart Scan cannot be buffered in the SGA buffer pool. Direct path reads can be performed for both serial and parallel queries. Direct path reads are buffered in process PGA (heap).

Result Set.

Data returned by the SQL processing layer. The SQL processing layer is in the Oracle Database. The data flowing from a Smart Scan is not a result set.

Exadata Smart Flash Cache.

Flash Cache in each of the Storage Servers. Not to be confused with Database Flash Cache which is Flash in the database grid and not compatible with Exadata. Smart Scan aggressively scans both HDD and Flash media concurrently. When data is present in the flash cache scan rates of 50 GB/s on Exadata Version 2 hardware are the norm for full rack configurations. Maximum theoretical scan rates (a.k.a., datasheet scan rates) for Exadata are *only* possible for fully offloaded scans. A fully offloaded scan is generated by a SQL query that finds no rows.

Storage Index.

Dynamic, in-memory indexes. The role of Storage Index technology is not to aid in locating data faster but instead to eliminate I/O. With Storage Indexes the Exadata Storage Server software can determine whether or not a given storage region contains rows relevant to the query and decide to not read the storage region. Storage Indexes are only examined during a Smart Scan.

I hope you’ll find this helpful.
