What is SOC in ArcGIS?

What is SOC in ArcGIS?

The components of ArcGIS Server can be summarized as: The GIS server consists of a server object manager (SOM) and one or more server object containers (SOCs). Web server—Hosts Web applications and Web services that use the objects running in the GIS server.

What is the default heap size?

By default, the JVM heap size is 1GB, which is usually enough to accommodate the data used by Task Engine. However, larger heap size may be required under some circumstances, for example, when the average size of the parameters in a task is very large.

How is heap size calculated?

In above environment, JVM allocated following default values :

1. Java heap size. InitialHeapSize = 64781184 bytes (61.7M) and MaxHeapSize = 1038090240 bytes (990M).
2. PermGen Size. PermSize = 21757952 bytes (20.75M), MaxPermSize = 174063616 bytes (166M)
3. Thread Stack Size. ThreadStackSize = 1024 kilobytes (1M)

What is an ArcSOC?

An instance is executed by a computer process called an ArcSOC – hence, the sock. When a client app makes a request to any service running on your ArcGIS Server site, such as to draw a map, geocode a data set, or run a geoprocessing job, that request is passed to an ArcSOC process on one of the machines in the site.

Is ArcGIS online FedRAMP?

ArcGIS Online is a FedRAMP tailored Low-Impact – Software as a Service (LI-SaaS) provided by Esri, a geospatial cloud service provider.

What is default JVM heap size?

The Java™ virtual machine (JVM) heap size setting directly relates to how many server instances can be started within a dynamic cluster on a specific node. You might need to modify the JVM heap size setting based on your environment configuration. The default value is 256 MB.

Is there a limit on the size of the heap?

Heap doesn’t have any limit on memory size. Stack memory is very limited. Creating too many objects on the stack can increase the risk of stack overflow. Random access is not possible. Variable storage will be overwritten, which sometimes leads to undefined behavior of the function or program.

What’s the difference between a stack and a heap?

Stack memory will never become fragmented whereas Heap memory can become fragmented as blocks of memory are first allocated and then freed. Stack accesses local variables only while Heap allows you to access variables globally. Stack variables can’t be resized whereas Heap variables can be resized.

Why is heap memory allocation not as safe as stack?

Heap memory allocation isn’t as safe as Stack memory allocation was because the data stored in this space is accessible or visible to all threads. If a programmer does not handle this memory well, a memory leak can happen in the program.

What does a heap mean in SQL Server?

A heap is a table that is stored without any underlying order. When rows are inserted into a heap, there is no way to ensure where the pages will be written nor are those pages guaranteed to remain in the same order as the table is written to or when maintenance is performed against it.
