This chapter describes the DIVArchive 7.5 operational boundaries and includes the following information:
The number of connections to the DIVArchive Manager is limited by the Manager and set in the Manager configuration file. The default configuration limit is two hundred. This boundary includes connections to GUIs, Actors and all API clients. When the configured limit is reached, the API will not create additional connections.
See the manager.conf file for more information.
The maximum number of simultaneous requests processed by the Manager is configurable in the manager.conf file as the value of the DIVAMANAGER_MAX_SIMULTANEOUS_REQUESTS parameter. The default value has been raised from two hundred to five hundred in DIVArchive 7.5. The maximum number has been verified up to two thousand. Additional simultaneous requests beyond the value set in this parameter are rejected by the Manager.
The number of API tasks that will be accepted to the API Processing Queue is configurable in the manager.conf file as the value of the DIVAMANAGER_API_TASK_QUEUE_SIZE parameter. The default value is two thousand and DIVArchive 7.5 has been verified at this value. If the queue is full subsequent commands are rejected.
Oracle recommends that a new connection between the Manager and an API client not be created for each request or command sent to the Manager. Whenever possible, let the connection remain open for the lifetime of the session or application.
Many requests require alpha numeric text parameters. Special characters can be used in these fields as defined in the following table. The request is rejected if an invalid special character is used. In a Windows environment, file and folder names cannot consist of one or more spaces, and cannot contain a double-quotation mark.

DIVArchive 7.5 supports absolute path names on both Windows and Linux up to a maximum of four thousand characters. Relative path names are limited to two hundred fifty-six characters on Windows systems (only).
A DIVArchive Windows local path is structured in the following order and terminated with a NUL character:
Drive_Letter:\Component_Name\Component_Name\File_Name.Extension
A DIVArchive Linux local path is structured in the following order:
/Component_Name/Component_Name/File_Name.Extension
The following are several example paths used in DIVArchive - Windows first and then Linux. The <NUL> character used in the example represents the invisible terminating null character for the current system code page and need not be typed in. The < and > characters are used in the examples for clarity only and must not be part of a valid path string.
Generic Path:
D:\Some_256-Character_Path_String<NUL> /Some_4000-Character_Path_String
Actor Executable:
D:\diva\diva\Program\Actor\bin\DIVArchive.exe /home/diva/diva/std_linux
Manager Configuration:
D:\diva\74\Program\conf\manager\manager.conf /home/diva/DIVA/Program/conf/manager/manager.conf
