R.A.C. - real world solutions&numbers

Does anyone know/have some real world examples, implementations
of Real Application Clusters? I need the exact numbers -
throughput increase, etc. Preferably from some "Oracle
independant" firm :-).
I looked in oracle.com, but couldn't find real numbers anywhere...
TIA

Hello.
I4m working on that right now. I4m doing load tests with a Linux
RAC and my web sites. Right now, I can tell you that I4m very
pleased with the load balancing of the RAC. I4m increasing the
loads to stress the thing...
I4m using my apaches servers (not IAS) with mod_plsql and a very
big aplication in the database more a very huge site (web
commerce) using php to connect to the RAC.
Very good results until now.
I don4t work on Oracle...

Enterprises are increasingly turning to cloud to drive agility and closely align IT resources to business needs. New or short-term projects and unexpected spikes in demand can be satisfied quickly and elastically with cloud resources, spurring more creativity and productivity while reducing the waste associated with over- or under-provisioning.
Figure 1) Cloud lets you closely align resources to demand.
Source: NetApp, 2015
While the benefits are attractive for many workloads, customer input suggests that even more can be achieved by moving beyond cloud silos and better managing data across cloud and on-premises infrastructure, with the ability to move data between clouds as needs and prices change. Hybrid cloud models are emerging where data can flow fluidly to the right location at the right time to optimize business outcomes while providing enhanced control and stewardship.
These models fall into two general categories based on data location. In the first, data moves as needed between on-premises data centers and the cloud. In the second, data is located strategically near, but not in, the cloud.
Let's look at what some customers are doing with hybrid cloud in the real world, their goals, and the outcomes.
Data in the Cloud
At NetApp, we see a variety of hybrid cloud deployments sharing data between on-premises data centers and the cloud, providing greater control and flexibility. These deployments utilize both cloud service providers (CSPs) and hyperscale public clouds such as Amazon Web Services (AWS).
Use Case 1: Partners with Verizon for Software as a Service Colocation and integrated Disaster Recovery in the Cloud
For financial services company BlackLine, availability, security, and compliance with financial standards is paramount. But with the company growing at 50% per year, and periodic throughput and capacity bursts of up to 20 times baseline, the company knew it couldn't sustain its business model with on-premises IT alone.
Stringent requirements often lead to innovation. BlackLine deployed its private cloud infrastructure at a Verizon colocation facility. The Verizon location gives them a data center that is purpose-built for security and compliance. It enables the company to retain full control over sensitive data while delivering the network speed and reliability it needs. The colocation facility gives Blackline access to Verizon cloud services with maximum bandwidth and minimum latency. The company currently uses Verizon Cloud for disaster recovery and backup. Verizon cloud services are built on NetApp® technology, so they work seamlessly with BlackLine's existing NetApp storage.
To learn more about BlackLine's hybrid cloud deployment, read the executive summary and technical case study, or watch this customer video.
Use Case 2: Private, Nonprofit University Eliminates Tape with Cloud Integrated Storage
A private university was just beginning its cloud initiative and wanted to eliminate tape—and offsite tape storage. The university had been using Data Domain as a backup target in its environment, but capacity and expense had become a significant issue, and it didn't provide a backup-to-cloud option.
The director of Backup turned to a NetApp SteelStore cloud-integrated storage appliance to address the university's needs. A proof of concept showed that SteelStore™ was perfect. The on-site appliance has built-in disk capacity to store the most recent backups so that the majority of restores still happen locally. Data is also replicated to AWS, providing cheap and deep storage for long-term retention. SteelStore features deduplication, compression, and encryption, so it efficiently uses both storage capacity (both in the appliance and in the cloud) and network bandwidth. Encryption keys are managed on-premises, ensuring that data in the cloud is secure.
The university is already adding a second SteelStore appliance to support another location, and—recognizing which way the wind is blowing—the director of Backup has become the director of Backup and Cloud.
Use Case 3: Consumer Finance Company Chooses Cloud ONTAP to Move Data Back On-Premises
A leading provider of online payment services needed a way to move data generated by customer applications running in AWS to its on-premises data warehouse. NetApp Cloud ONTAP® running in AWS proved to be the least expensive way to accomplish this.
Cloud ONTAP provides the full suite of NetApp enterprise data management tools for use with Amazon Elastic Block Storage, including storage efficiency, replication, and integrated data protection. Cloud ONTAP makes it simple to efficiently replicate the data from AWS to NetApp FAS storage in the company's own data centers. The company can now use existing extract, transform and load (ETL) tools for its data warehouse and run analytics on data generated in AWS.
Regular replication not only facilitates analytics, it also ensures that a copy of important data is stored on-premises, protecting data from possible cloud outages. Read the success story to learn more.
Data Near the Cloud
For many organizations, deploying data near the hyperscale public cloud is a great choice because they can retain physical control of their data while taking advantage of elastic cloud compute resources on an as-needed basis. This hybrid cloud architecture can deliver better IOPS performance than native public cloud storage services, enterprise-class data management, and flexible access to multiple public cloud providers without moving data. Read the recent white paper from the Enterprise Strategy Group, “NetApp Multi-cloud Private Storage: Take Charge of Your Cloud Data,” to learn more about this approach.
Use Case 1: Municipality Opts for Hybrid Cloud with NetApp Private Storage for AWS
The IT budgets of many local governments are stretched tight, making it difficult to keep up with the growing expectations of citizens. One small municipality found itself in this exact situation, with aging infrastructure and a data center that not only was nearing capacity, but was also located in a flood plain.
Rather than continue to invest in its own data center infrastructure, the municipality chose a hybrid cloud using NetApp Private Storage (NPS) for AWS. Because NPS stores personal, identifiable information and data that's subject to strict privacy laws, the municipality needed to retain control of its data. NPS does just that, while opening the door to better citizen services, improving availability and data protection, and saving $250,000 in taxpayer dollars. Read the success story to find out more.
Use Case 2: IT Consulting Firm Expands Business Model with NetApp Private Storage for Azure
A Japanese IT consulting firm specializing in SAP recognized the hybrid cloud as a way to expand its service offerings and grow revenue. By choosing NetApp Private Storage for Microsoft Azure, the firm can now offer a cloud service with greater flexibility and control over data versus services that store data in the cloud.
The new service is being rolled out first to support the development work of the firm's internal systems integration engineering teams, and will later provide SAP development and testing, and disaster recovery services for mid-market customers in financial services, retail, and pharmaceutical industries.
Use Case 3: Financial Services Leader Partners with NetApp for Major Cloud Initiative
In the heavily regulated financial services industry, the journey to cloud must be orchestrated to address security, data privacy, and compliance. A leading Australian company recognized that cloud would enable new business opportunities and convert capital expenditures to monthly operating costs. However, with nine million customers, the company must know exactly where its data is stored. Using native cloud storage is not an option for certain data, and regulations require that the company maintain a tertiary copy of data and retain the ability to restore data under any circumstances. The company also needed to vacate one of its disaster-recovery data centers by the end of 2014.
To address these requirements, the company opted for NetApp Private Storage for Cloud. The firm placed NetApp storage systems in two separate locations: an Equinix cloud access facility and a Global Switch colocation facility both located in Sydney. This satisfies the requirement for three copies of critical data and allows them to take advantage of AWS EC2 compute instances as needed, with the option to use Microsoft Azure or IBM SoftLayer as an alternative to AWS without migrating data. For performance, the company extended its corporate network to the two facilities.
The firm vacated the data center on schedule, a multimillion-dollar cost avoidance. Cloud services are being rolled out in three phases. In the first phase, NPS will provide disaster recovery for the company's 12,000 virtual desktops. In phase two, NPS will provide disaster recover for enterprise-wide applications. In the final phase, the company will move all enterprise applications to NPS and AWS. NPS gives the company a proven methodology for moving production workloads to the cloud, enabling it to offer new services faster. Because the on-premises storage is the same as the cloud storage, making application architecture changes will also be faster and easier than it would be with other options.

I was looking for some real world "Best Practices" of deploying J2EEapplications
into a Production Weblogic Environment.
We are new at deploying applications to J2EE application servers and arecurrently
debating 2 methods.
1) Store all configuration (application as well as Domain configuration)in properties
files and Use Ant to rebuild the domain everytime the application isdeployed.
I am just a WLS engineer, not a customer, so my opinions have in some
regards little relative weight. However I think you'll get more mileage out
of the fact that once you have created your config.xml, checking it into src
control, versioning it. I would imagine that application changes are more
frequent than server/domain configuration so it seems a little heavy weight
to regenerate the entire configuration everytime an application is
deployed/redeployed. Either way you should check out the wlconfig ant task.
Cheers
mbg
2) Have a production domain built one time, configured as required andalways
up and available, then use Ant to deploy only the J2EE application intothe existing,
running production domain.
I would be interested in hearing how people are doing this in theirproduction
environments and any pros and cons of one way over the other.
Thanks.

Real World Item Level Permission Performance?

I am considering implementing item level permission on a list we use. I've seen all the articles online cautioning not to do this with lists of more than 1000 items, but the articles seem to have little detailed information about the actual impact and what
causes the performance issues. Additionally, they seem to refer to document libraries more than lists. I'd like some feedback about what might occur if we were to use item level security in our situation.
Our situation is this: list of current ~700 items in a sharepoint list. Expected to grow around 700 items per year. The list has about 75 fields on it. We have 8 active-directory groups that have access to the list, based upon company department. Each
item in the list can apply to one or more departments. The groups represent around 100-150 different unique users.
We would like to use item level security to be set via workflow, to enable particular groups to access the item based upon their group membership. For example, if the list item is for the HR department, then the HR group has access. If the item is for IT,
then the IT group has access (and HR wouldn't).
That's it. There would be no nesting of items with multiple permission levels, no use of user-level ACLs on the items, etc.
Thoughts about this configuration and expected performance issues? Thanks for any feedback!

Just an update for anyone who finds this thread:
I converted our data into a test SharePoint list with 1500 rows. I then enabled full item-level security, with restrictions to hide data not created by the person.
I then set individual permissions for each item that included 2-3 AD groups with different permissions--contribute, full ownership, etc, and 2-3 individuals with varying permissions. The individuals represented around 50 total people.
After the permissions were set I then did a comparison of loading individual views and the full data set in Standard and Datasheet views, for both myself as an administrator with full list access and with several of the individuals who only had access to
their designated items--typically 75-100 of the total list.
The results were that I found no discernable difference in system performance from the user interface level while loading list views after the item level security was configured in this way. I understand this will vary based up
hardware configuration and exact permission configuration, but in our situation the impact of item level security on a list of 1500 items had very little, if any, negative performance impact. Note that I didn't check performance at the database server level,
but I'm assuming the impact there was minimal since the front-end user experience was unaffected.
I expect we'll put this solution into place and if we do I'll update this post when we have additional real-world usage information.

T61p 200gb at 7200rpm buffer size and real world performance?

Hi, I wanted to confirm what the buffer size on the 200gb 7200 option of the T61p had... there seems to be conflicting information regarding this model. I'd also appreciate any information regarding the real world performance of this particular drive...
Thanks!

Solved!
Go to Solution.

both the hitachi and seagate 200GB/7200RPM drives used in the T61p have 16MB of onboard cache. performance tests of these two drives are scattered across the internet. search google for "hitachi 200GB 7K200" and "seagate 200GB 7200.3" respectively.

LAP to WLC - Maximum RTT Delay Limits in the real World!

Hi,
I've seen the design related info that says the maximum RTT between the LAP and its WLC has to be less than 300ms.
I'm working on a solution where a number of the APs will be across WAN links where the RTT are from 250ms to 323ms. Has anyone experience of the types of problems that occur when the 300ms is exceeded, or indeed is there a real world RTT value that we should work to rather than the stated values? Has anyone installed Aps where the RTT is greater than 300ms and is it reliable? I ask as I can find no references to this on Cisco.com or in the CAPWAP RFC and our competiors (in the bid) using non-Cisco products are very clear that this is not a problem for them.
Any guidance much appreciated as usual.
Thanks. Phil.C

IMO
Voice issues would be the biggest concern. Part of the reason we keep a 300ms RTT is because you need to have 150ms RTT for voice to work cleanly. While the AP may stay connected at 323ms, you will most likely have some voice issues.

Usage of CAF in real World scenario

Hi All,
iam trying to understand Netweaver CAF(core & GP) from a technical perspective. all the marketing information that SAP provides does not give me enough information to understand how it can solve real world problems. i would appreciate it if anyone of you can explain me in detail how Netweaver CAF can solve the problem and what would have been your solution if Netweaver CAF was not in place.
Please explain with some simple scenario.
Thanks & Regards,

Routing real world IP to computer on internal Network

I have a OS X 10.4 server providing DHCP and NAT to a private subnet (192.168.2.X) and I was wondering if anyone had any experience in routing a real world IP to one of the computers on that network. I have several additional real world IP's given to me by the DSL service provider and I wanted to route traffic from one of them to one of the machines. Is this even possible?

Well, I am familiar w/port forwarding but the situation is this:
ISP gives me IP numbers A,B & C
Xserve has IP A, provides NAT & DCHP service to network of macs.
I want to be able to assign IP B to one mac on that network
Is that possible or am I going to have to run a cable from DSL modem to the mac that I want to give IP B to, bypassing the server?

ESATA 6g, USB 3 on PCI, real world

I am looking to buy a
CalDigit FASTA-6GU3
2 Port USB 3.0 & eSATA 6Gb/s Host Adapter
to put in my 2008 Mac Pro PCI slot to run an external Blu-Ray writer and hard drive enclosure off the eSATA ports.
Looking for info on what real-world Gps/Mbps the Mac Pro PCI slot can actually handle -- it is great if the card is 6Gbps eSATA & 5Gbps USB3.0 -- but the bottleneck is what the PCI bus can move (also limited by what the hadrdrive and writer can actually read/write).
I read on the reviews that the Mac Pro PCI bus can only perform tops 500Mbps (slightly above Firewire 400Mbps).
I also read the actual PCI card performance was limited to 250MBps due to its PLX chip design.
As USB2.0 is based on 480Mbps -- I have to wonder what all these numbers mean.
Can anyone put this into layman's perspective -- why put a 6Gps eSATA and USB 3.0 card in a PCI slot that is limited to 250Mbps?

Bytes will come to byte you if you think they are bits.
Kilobytes was the same issue. Or gigabits and bytes.
10 bits to a byte basically. sometimes 8 bits if there is no check bit.
Wikipedia is your friend, more so than Google. And there are dictionaries online of tech terms.
Some poeple come here talking about their MacPro except that they don't know what a 65lbs Mac is and my guess is there are a dozen notebook users asking.
The Sonnet E4P ~$250 w/ 4 x eSATA ports is nice for adding direct connect to SATA devices, more than enough bandwidth.
Your Mac has those four internal SATA2 drive bays. Those are all on a single shared controller bus, so while in theory you can get 275MB/sec max from each, there also is NOT full 1GB let alone 1.2 (1200MB/sec) but rather 750MB/sec - more than enough for most disk drives still. Only when you got to SSDs that it was more apparent.
Here is what your Mac's Serial ATA drives and bus are offering in bandwidth performance, sortof.
180MB/sec is about the max of 4TB enterprise drive, or WD 10K latest VelocityRaptors.
SATA2 SSD was about 275MB/sec also, and 450-500/550 (max, writes are often less with SSDs, reads tend to do very well, but it is the very high I/O's per second that they shine, along with lowest response time in seeks being 1/1000th - instead of being 4-12 milliseconds you are into less than 1.0 nanoseconds.
Geeks were happy with a Base2 numbering - binary 1's and 0's and base16 whereas Apple and others now wanted to change one gigabyte from being binary 1024MB and turn it into 1000MBs. The dumbing down of math, specs, and the i-ification of consumer devices. iDevice, iOS and consumers that never liked those 1024 binary and hex based numbering system.

> but the part about DNG has convinced me to dive deeper in it and give it a go
When working in a Bridge/Camera Raw/Photoshop workflow, I tend to ingest the actual native raw files, do initial selects and gross edits and basic metadata work via templates and THEN do the conversion to DNG. I'll use the DNG as my working files and the original raws as an archive. I tend to do this more with studio shoots. I tend to use Lightroom when I'm on the road.
When working in Lightroom first, I tend to ingest and convert to DNG upon ingestion (when in the road working on a laptop) while using the backup copyusually working on a pair of external FW drives one for working DNG files and 1 for BU of the original raws. Then, when I get back to the studio I make sure I write to XMP and export the new shoot as a catalog and import into my studio copy of Lightroom. Then I'll also cache the newly imported images in Bridge as well so I can get at the image either in Bridge or Lightroom.
It's a bit of a chore now since I do work in Camera Raw a lot (well, DOH, I had to to do the book!) but I also keep all my digital files in a Lightroom catalog which is now up to about 74K...
Then, depending on what I'll need to do, I'll either work out of LR or Bridge/Camera Raw...
If I'm doing a high-end final print, I generally process out of Camera Raw as a Smart Object and stack multiple layers of CR processed images...if I'm working on a batch of images I'll work out of Lightroom since the workflow seems to suit me better.
In either event, I've found DNG to be better than native raws with sidecar files.

RAID test on 8-core with real world tasks gives 9% gain?

Here are my results from testing the software RAID set up on my new (July 2009) Mac Pro. As you will see, although my 8-core (Octo) tested twice as fast as my new (March 2009) MacBook 2.4 GHz, the software RAID set up only gave me a 9% increase at best.
Specs:
Mac Pro 2x 2.26 GHz Quad-core Intel Xeon, 8 GB 1066 MHz DDR3, 4x 1TB 7200 Apple Drives.
MacBook 2.4 GHz Intel Core 2 Duo, 4 GB 1067 MHz DDR3
Both running OS X 10.5.7
Canon Vixia HG20 HD video camera shooting in 1440 x 1080 resolution at “XP+” AVCHD format, 16:9 (wonderful camera)
The tests. (These are close to my real world “work flow” jobs that I would have to wait on when using my G5.)
Test A: import 5:00 of video into iMovie at 960x540 with thumbnails
Test B: render and export with Sepia applied to MPEG-4 at 960x540 (a 140 MB file) in iMovie
Test C: in QuickTime resize this MPEG-4 file to iPod size .m4v at 640x360 resolution
Results:
Control: MacBook as shipped
Test A: 4:16 (four minutes, sixteen seconds)
Test B: 13:28
Test C: 4:21
Control: Mac Pro as shipped (no RAID)
Test A: 1:50
Test B: 7:14
Test C: 2:22
Mac Pro config 1
RAID 0 (no RAID on the boot drive, three 1TB drives striped)
Test A: 1:44
Test B: 7:02
Test C: 2:23
Mac Pro config 2
RAID 10 (drives 1 and 2 mirrored, drives 3 and 4 mirrored, then both mirrors striped)
Test A: 1:40
Test B: 7:09
Test C: 2:23
My question: Why am I not seeing an increase in speed on these tasks? Any ideas?
David
Notes:
I took this to the Apple store and they were expecting 30 to 50 per cent increase with the software RAID. They don’t know why I didn’t see it on my tests.
I am using iMovie and QuickTime because I just got the Adobe CS4 and ran out of cash. And it is fine for my live music videos. Soon I will get Final Cut Studio.
I set up the RAID with Disk Utility without trouble. (It crashed once but reopened and set up just fine.) If I check back it shows the RAID set up working.
Activity Monitor reported “disk activity” peaks at about 8 MB/sec on both QuickTime and iMovie tasks. The CPU number (percent?) on QT was 470 (5 cores involved?) and iMovie was 294 (3 cores involved?).
Console reported the same error for iMovie and QT:
7/27/09 11:05:35 AM iMovie[1715] Error loading /Library/Audio/Plug-Ins/HAL/DVCPROHDAudio.plugin/Contents/MacOS/DVCPROHDAudio: dlopen(/Library/Audio/Plug-Ins/HAL/DVCPROHDAudio.plugin/Contents/MacOS/DVCPROHD Audio, 262): Symbol not found: _keymgr_get_per_threaddata

The memory controllers, one for each cpu, means that you need at least 2 x 2GB on each bank. If that is how Apple set it up, that is minimal and the only thing I would do now with RAM is add another 2 x 2GB. That's all. And get you into triple channel bandwidth.
It could be the make and model of your hard drives. If they are seagate then more info would help. And not all drives are equal when it comes to RAID.
Are you new to RAID or something you've been doing? seems you had enough to build 0+1 and do some testing. Though not pleased, even if it works now, that it didn't take the one time.
Drives - and RAIDs - improve over the first week or two - which, before commiting good data to them - is the best time to torture, run them ragged, use Speedtools to break them in, loosen up the heads, scan for media errors, and run ZoneBench (and with 1TB, partition each drive into 1/4ths).
If Drive A is not identical to B, then they may deal with an array even worse. And no two drives are purly identical, some vary more than others, and some are best used in hardware RAID controller environments.
Memory: buying in groups of three. okay. But then adding 4 x 4GB? So bank A with 4 x 2GB and B with twice as much memory. On Mac Pro, 4 DIMMs on a bank you get 70% bandwidth, it drops down from tri-channel to dual-channel mode.
I studied how to build or put together a PC for over six months, but then learned more in the month (or two) after I bought all the parts, found what didn't work, learned my own short-comings, and ended up building TWO - one for testing, other for backup system. And three motherboards (the best 'rated' also had more trouble with BIOS and fans, the cheap one was great, the Intel board that reviewers didn't seem to "gork" actually has been the best and easiest to use and update BIOS). Hands on wins 3:1 versus trying to learn by reading for me, hands-on is what I need to learn. Or take car or sailboat out for drive, spin, see how it fares in rough weather.
I buy an Apple system bare bones, stock, or less, then do all the upgrades on my own, when I can afford to, gradually over months, year.
Each cpu needs to be fed. So they each need at least 3 x 1GB RAM. And they need raw data fed to RAM and cpu from disk drives. And your mix of programs will each behave differently. Which is why you see Barefeats test with Pro Apps, CINEBENCH, and other apps or tools.
What did you read or do in the past that led you to think you need RAID setup, and for how it would affect performance?

EJB 3.0 in a real world open source project. Great for coding reference!

If you are interested in seeing EJB 3.0 implemented in a real world project (not just examples) or if you are interested in learning how to use them I suggest you to take a look a the open source project Overactive Logistics.
It has been written totally using EJB 3.0 (session and entity beans) I found it very helpful in solving several technical situations I was facing.

Character Styles in the Real World

Rick:
Thanks for your efforts, and let me add my Amen to both
subjects (on file locations and on Character styles).
My real-world use of Character styles is a combination usage
of Paragraph and Character styles for Notes: I have a Paragraph
style called Note, which simply adds margins of .15in Left, 10pt
Top, and 8pt Bottom. Within this paragraph style, multiple labels
announce the type of Note with the use of Character styles
NoteLabel (Navy), RecommendLabel (Teal), CAUTIONLabel (Purple), and
WARNINGLabel (Red).
This way, you can change the color of one or more labels
without worrying about the paragraph settings (or vice versa).
Also, when placing a Note inside a table cell (which might
have limited horizontal space, especially with three or four
columns), we still use the "Label" character styles but
without the Notes paragraph style. This still sets off the
text visually, without adding unnecessary extra vertical space.
Thanks again, Rick!

1. A system which allocates and dispatches crews, trucks, backpack hoses, spare socks, etc to bushfires (wildfires to you). It operates between two Government departments here in Australia. Each of those despatchable items is a remote object and there have been up to 50,000 active in the system at a time during the hot summer months. This is a large and life-critical system.
2. A monitoring system for cable TV channels. A piece of hardware produces a data stream representing things like channel utilization, error rates, delay, etc and this is multiplexed via RMI to a large number of operator consoles. Again this is a major and business-critical system.
And of course every J2EE system in existence uses RMI internally, albeit almost entirely RMI/IIOP.

Raw files from the new Nikon D810 will not open with either Photoshop CS5.1 or Lightroom 4. When will a real Adobe solution be available to work with Raw (NEF) files in their native format, using CS5.1 and LR4?

Raw files from the new Nikon D810 will not open with either Photoshop CS5.1 or Lightroom 4. When will a real Adobe solution be available to work with Raw (NEF) files in their native format, using CS5.1 and LR4?

Clarification: this is a user forum; you are not addressing Adobe here.
The answer to your question as phrased is: never.
CS5 is history and it is not longer supported. There will not be any updates or bug fixes for CS5.
You need to convert the raw NEF files from your D810 to raw DNGs using the free, standalone Adobe DNG Converter 8.6 RC (beta), the first version ever to support that camera..

PI Implementation Examples - Real World Scenarios

Hello friends,
In the near future, I'm going to give a presentation to our customers on SAP PI. To convince them to using this product, I need examples from the real world that are already implemented successfully.
I have made a basic search but still don't have enough material on the topic, I don't know where to look actually. Could you post any examples you have at hand? Thanks a lot.
Regards,
Gökhan

New Enterprise Manager Book on Advanced EM Techniques for the Real World

Dear Friends,
I am pleased to say my first EM book can be ordered now.
Oracle Enterprise Manager Grid Control: Advanced Techniques for the Real World
[http://www.rampant-books.com/book_1001_advanced_techniques_oem_grid_control.htm]
Please let your colleagues and friends and clients know – it is the first book in the world to include EM 11g Grid Control. It is a great way for people to understand the capabilities of EM.
Oracle’s Enterprise Manager Grid Control is recognized as the IT Industry’s leading Oracle database administration and management tool. It is unrivalled in its ability to monitor, manage, maintain and report on entire enterprise grids that comprise hundreds (if not thousands) of Oracle databases and servers following an approach that is consistent and repeatable.
However, Enterprise Manager Grid Control may seem daunting even to the most advanced Oracle Administrator. The problem is you know about the power of Enterprise Manager but how do you unleash that power amongst what initially appears to be a maze of GUI-based screens that feature a myriad of links to reports and management tasks that in turn lead you to even more reports and management tasks?
This book shows you how to unleash that power.
Based on the Author’s considerable and practical Oracle database and Enterprise Manager Grid Control experience you will learn through illustrated examples how to create and schedule RMAN backups, generate Data Guard Standbys, clone databases and Oracle Homes and patch databases across hundreds and thousands of databases. You will learn how you can unlock the power of the Enterprise Manager Grid Control Packs, PlugIns and Connectors to simplify your database administration across your company’s database network, as also the management and monitoring of important Service Level Agreements (SLAs), and the nuances of all important real-time change control using Enterprise Manager.
There are other books on the market that describe how to install and configure Enterprise Manager but until now they haven’t explained using a simple and illustrated approach how to get the most out of your Enterprise Manager. This book does just that.
Covers the NEW Enterprise Manager Grid Control 11g.
Regards,
Porus.
