FileMaker Error exceeding Capacity

If you're taking full advantage of hosting your Claris FileMaker app with FileMaker Server, you are likely using Perform Script on Server (PSOS) in your scripts, as well as scheduled scripts run on a given interval. Occasionally, your users might see an error that the host capacity was exceeded.

The capacity error

FileMaker Host Capacity Exceeded, error code 812, occurs when the number of concurrent Script Engine Sessions exceeds the limit set in the server configurations. The Script Engine sessions relates to both PSOS sessions and script schedules configured in the FileMaker Server Admin Console.

Resolving the FileMaker Server capacity issue

The standard way to resolve error 812 messages is to modify the ServerConfig setting ScriptSessions.

FileMaker Server 14 - 16

For versions of FileMaker Server 14, 15, and 16, the configuration of the script session limit is managed in the FileMaker Server Admin Console, under the Database Server > FileMaker Clients tab. The setting Maximum Simultaneous Script Sessions will determine the limit on the number of script sessions and can be set to any value between 0 and 500.

FileMaker Server 17+

For versions of FileMaker Server 17+, the management of the configuration of the Script Sessions limit can be accessed by the Command Line Interface tool "fmsadmin". In order to view the current value set for the "Maximum Simultaneous Script Sessions" limit, use the following command in a Command Prompt or Terminal window: fmsadmin get serverconfig. ScriptSessions will determine the limit. To modify the limit, use the following command: fmsadmin set ScriptSessions=###, where ### is an integer limit between 0-500 as the new limit to the script sessions. Note that the admin console account credentials are required to get and set the serverconfig in the command line.

But wait, there's more!

If the setting has been modified to the maximum allowable value of 500 Script Sessions and users still see the error message that the "Host Capacity Exceeded" then there are two additional solutions to consider.

First, the server may lock up and not complete processing scripts, which means it won't release the resources. If there are hanging PSOS or schedules in the Client Section of the FileMaker Server Admin Console, then restart the FileMaker Scripting Engine process with the following command in a command prompt or terminal session on the FileMaker Server: fmsadmin restart FMSE -y. The command will stop and start the scripting engine, which should stop the processing of the hung scripts and release the sessions; it will also produce errors in the Event log of scheduled scripts failing if they processed during the time that the command was entered.

Second, reduce the number of calls so that there are less than 500 concurrent script session at any given time. In this scenario there are no locked up scripts and the maximum script session limit is set to 500. The only way to prevent error 812 will be to examine the FileMaker databases hosted on the server and refactor the solution to limit the number of PSOS calls made to the server.

FileMaker Hosting in Hawaii

Aloha, from Hawaii

Ottomatic is excited to welcome Honolulu, Hawaii as one of our newest data center locations!

We are here to empower FileMaker developers, businesses, and schools at the center of the Pacific. With Hawaii becoming a fast-growing spot for data, we want to further demonstrate our commitment to cloud-first and the modern FileMaker Revolution in offering Ottomatic’s high-performance, low-latency FileMaker Cloud Hosting in Honolulu.

The importance of decreasing latency

A hosting rule of thumb: host your FileMaker database in a location close to your users. Latency is the time it takes for data to move from its origin to its destination. The closer your users are to the data center, the better your odds for a faster experience for your users.

Meet DRFortress, Our Data Center Partner

DRFortress is the largest, and the only carrier-neutral, data center and cloud marketplace operating in Hawaii. The data center is a whopping 55,000+ sq. ft. facility located at the Airport Industrial Park in Honolulu. They are connected to Hawaii’s largest set of low-latency and neutral network carriers and are dedicated to providing the best services and support by their operations team with over 100+ cumulative years of data center service expertise.

Without a local provider, FileMaker solutions in Hawaii previously meant hosting in Los Angeles or Japan, both with massive amounts of latency to the center of the Pacific. With the addition of this data center, your FileMaker apps will experience a massive performance boost including super fast 10GB connectivity, Otto bundled at no cost, and our experts monitoring and managing your cloud instance 24/7.
