Yes, this is the machine with the ArcGIS Monitor Server.  As per the instructions set by ESRI, I turned 'off' during install.   here is the control panel >> Programs list.     ... View more

I've been running red lights since 2009 (kidding of course) -  technically 100% possible.. neither are 'legal'.  ESRI and Google relationship dissolved some time ago. Neither allow either to mix their products since 10.3. next up:  how to scrape tiles for free!  After that:  using Geocoders in batches for free! ... View more

10.9 is not ideal as 10.9 is a 'short release'.   it would have to be 10.9.1 ... View more

Hi Jonathan, Great to hear from you. I guess the reason why i do not say portal is HA is really due to me losing the battle of that argument with corporate EAs.  HA means all components can work actively, not that 'part' of it fails over.  Yes, the web adaptors can both work, portal itself can as well.  what can not do HA is the darn PosgreSQL. which makes Portal software not HA.  Content directory is not a challenge as one can set up content directory on a NAS which inherently has HA built into it.  typically three network channels (fibre/cable) with a complex RAID. so no problem there. Correct, OS patching has different schedules for each of the machines I had setup, including the License server and the FO license server, pairs of the AGS servers, one of each portal and Web servers. all through an NLB, all using VIPs.  The corruption occurred when the VM team had patched and rebooted one side, and begun patching the other, but the patch was small enough that the VM restart cycle time was shorter than the (4 minutes) it takes for Portal to replicate over... it was all over at this point.  I am aware that newer portal versions have reduced this time... to maybe under two minutes. (which comes to another point, not able to configure Active Directory LDAP to a VIP, only IPs... (that is for another conversation). Id love to describe the corruption that happened but I don't think there is enough room on this forum . There have been a few cases on this (case #02200912).  Escalated to Redlands without resolve (Esri Case #02377858) I am confident there is corruption within PostgreSQL, but have never had the time to look at this further. I can come by and discuss if you are attending the International Developer Summit.  ... View more

You are correct, it is due to the underlying PostgreSQL technology. Funny, I have another thread response going into details.  I've had to deal with corruption of replication, quite fun. From an architecture standpoint one has to really weigh the benefits vs the risk for enabling active/passive portal for what business wants.  To an EA, HA means all points are HA, otherwise it is not 'ha' even if some components are.  Portal would not classify an Enterprise GIS stack as true HA.  My approach is reduce the amount of single points of failure within cost reason and business benefit. (e.g. SQL always on / HANA inmem HA is by no means cheap and will more than likely be single points of failure).  With my experience, Portal, even at 10.7+ is just too sensitive to monthly OS patches and constant cycles or network traffic disruptions. ...

True, except to clarify, Portal is not HA( High -availability).  It is Active/passive. or in ESRI terms Primary/Secondary.  Calls don't load balance, they all go to one side, the set active side.  there is an underlying posgresql replication that occurs when switching. this is not HA.  And one can really bugger it up if you patch the OS lets say and restart and don't allow enough time for the replication across to take place.  True HA, this would not be...(like AGS) ...

ESRI allows you obtain a $64,000+ piece of software by purchasing it through the EDN for $1800.  Sorry to hear that free isn't available to meet everyone's needs.  But hey, never know, maybe ESRI will... good luck! ... View more

Is the Designer available for download to use on-premise?  Or is there a workflow to allow designing and then leveraging on-premise Portal/Enterprise setups that do not have 'external internet accessibility' ? Large organizations such as where I am, do not allow external facing Internet access GIS Enterprise architecture. ... View more

I'd like to comment on the cost.  Eighteen hundred ($1800) is nothing when you look at the benefits you gain from having access to the software, comparing against the production / staging core license costs.  To say it is 'a lot' is you are missing the value completely and focusing on the measly 1800. Having my own dev environment has paid dividends 50x over. Think of it as continuing education costs, slightly more than daily coffee runs that puts you in the elite group.   ... View more

Azin Sharaf wrote: 4-core license model is for ArcGIS Server site or ArcGIS Server machines? What happens if we have 1 ArcGIS Server site and two machines (each has 4 cores)  (HA mode)? Then you are required to buy two (2)  4-core Enterprise Standard or Advanced licensing for each discrete installation instance.  FYI: 4-core Enterprise ArcGIS Server is a separate SKU vs buying additional core licenses.   The wording would be as follows - Any discrete NODE (VM) must start with 4-core license purchase.  Each discrete setup can add additional cores (any number) thereafter (separate SKU when purchasing)  Any discrete site can be added to a SITE.  (this used to be called NODES and CLUSTERS). ...

Perhaps the google statement should answer your question enough? Google makes no claims as to the accuracy of the coordinates in Google Earth. These are provided for entertainment only and should not be used for any navigational or other purpose requiring any accuracy whatsoever. Our imagery varies from sub-meter resolution in major cities to 15 meter resolution for most of the earth’s surface, with a global base resolution of 1KM. Since our database is constantly being updated, we cannot state a specific resolution for any geographic region. Google acquires imagery from many different sources with many different file formats, projections and spectral characteristics. All imagery sources are fused into a single global database with a proprietary format that has been developed for the specific purpose of streaming to our client software. the answer to your question, 'how accurate' really depends on where and what the source was.  could range from 2meters to many meters...  the decision is really then, how accurate do you NEED it to be.  I see legal boundaries cut through buildings on imagery for a reason... its not accurate enough. ...
