I am publishing tile map service, with 4 level of detils. Suddenly, Portal website doesn't load ("site cant be reached" error). When I ping to the site, it replies.  The space of HDD is 500Gb. And there are still lots of HDD space left. The server has 2 physical cores (4 logical cores) and 16GB of RAM. The server host Arcgis Server and Portal. Why the Portal failed to load ? What do I need to check ? Is it because of publishing tile service ? thanks ... View more

I am in the middle of copying a feature class with large attachment (91K records attachment). The process take 2 hours for copying around 19K of attachment records. How to speed up the process ? Mathematically, the whole copying will take approx another 8 hours . I am using EGDB on postgresql ... View more

I have a problem. I am running a field survey involving 100 surveyors (so far, the highest number of surveyors are just 40 at the same time), 40 QC personnels (the highest number achieved so far). The table itself has 36K points and 120 attributes that need to be updated attributively.  Attributes are updated based on the question asked. So not all 120 attributes are updated actively at one time. The fieldmap has 3 layers (from the same table) with each layer has different filter. The combined data (if all layers are selected) are much less than 36K. I utilize visibility scale too to minimize load. The surveyors are working from morning till afternoon. At nite, QC personnel will begin to work using ArcGIS Pro and they access the data using Feature Service (they do not access background layers using Map Service. Instead they are using offline data to reduce server load). They use Query Definition for certain attributes with certain order that are in line with the indexes on rdbms postgresql 13. The apps also has a background layer (map service) with 36K polygons. I set the visibility of this layer minimum at city level and maximum at building level The configuration of the feature service *now* (been running for 1 hour now and there are 83 data inserted from 23 surveyors) are as follows : - Shared Instance (previously prior to server down was Dedicated, max instance 9, min instance 7, max time client can use a service 660s, idle time instance be kept running 1800)  - all antialising are off. I assume this antialising contributes to more processing when turned on. - recycle every 24H at 00:00AM With server config settings as follows: - Web server maximum heap size (in MB): -1 - SOC maximum heap size (in MB): 128 (previously prior to server down was 512) Why was it prone to crashing down ? The server (the whole server, literally) crashed every once for 5 days for 2 week straight. But when I changed it to 512M of SOC maximum heap size, it crashed 5 times in 1 day !  I was thinking that with dedicated instance and large heap memory will be more stable. But it *seems* it has adverse effect. My system design, running on AWS : 1 server for egdb (Linux-amd64-6.5.0-1014-aws, vcpu 2, 8GB RAM, 500GB HDD), 1 server for Arcgis Server and Portal (4 vCPU  running on 2 physical processor, 16GB of RAM, 500GB of HDD)   and 1 server for License running on windows (in case you want info). My arcgis server statistics looks like this :   Need some advice to run the whole thing smoothly, at least without crashing.     ... View more

I updated the content some coloumns that are not being used. I do not modify the table schema, nor changing the coloumn width. Here is the script : update schema1.tabledata set x = NULL, y = NULL, columnn1 = NULL, foto_1 = NULL, foto_2 = NULL where vendor = ('vendorname') This "tabledata" feature class is published as feature layer and being consumed by field map apps and also some qc work via arcgis pro (using REST). Why suddenly the feature service do not contain any data ? I have checked the filter but they all fine, i have restarted the feature service, I also check if NULL is not allowed. But still the feature service show no data In fact, those coloumns that I have just reset to NULL  do not participate in the apps. The content of the feature class itself is fine when I check it via arcgis pro. I can see all the data there. I am using Postgresql running on Linux with Arcgis Enterprise 11.0 ... View more

Say I have a point feature class with 100K points that fall into 4 categories. This will be published into a map service that will be used by many clients. Which one is better to reduce server load : - publishing all 100K data and then filter it in web map by their categories - filter the data by categories in arcgis pro and then publish it   thanks ...
