Note!Due to the agents' relationships within a workflow configuration, ensure that you have added all agents and routes in order to initiate a workflow. |
Each agent in the workflow configuration has a specific configuration configuration dialog named after the agent type. You can access these configurations by double-clicking the agent or the route. Subsequently you can also click on the 
button when selecting an agent or a route. This opens a dialog that contains different agents and route-based options. See Agent Options and Route See https://infozone.atlassian.net/wiki/spaces/UEPE4D/pages/edit-v2/304401288#Agent-Options and https://infozone.atlassian.net/wiki/spaces/UEPE4D/pages/edit-v2/304401288#Route-Options for more information.
When an agent is deployed into the workflow template it receives a default name located underneath it. The same applies to routes when they are added. These names may be modified to ease identification in monitoring facilities and logs.

Common Agent Services
Some agent configuration dialogues are optionally equipped with additional tabs holding configurations for different common services. This section describes the general services that are available. The user guide for each agent, in turn describe what services it uses.
...
Thread Buffer Tab
By default, a batch workflow uses one active thread at a time. By configuring a buffer storage for an agent, it is possible for yet another thread to be created. This is also called multithreading. One thread populates the buffer, and another pulls it for data. Adding yet another buffer for another agent adds yet another thread, and so on.
This is especially useful in complex workflows with many agents. All batch agents that receive UDRs can use this functionality.
| Note |
|---|
Note!A workflow that is configured with multithreading can only handle data of the UDR type. If bytearrays are routed into an agent using this service, an exception is thrown. |
Open the Configuration dialog of the agent and select the Thread Buffer tab. The tab is present in batch processing and batch forwarding agents.
...
The Thread Buffer tab
Setting | Description |
|---|---|
Use Buffer | Enables multithreading. For further information, see Multithreading (4.3). |
Print Statistics | Statistics to be used when trying out where to use the Thread Buffer in the workflow. After each batch execution, the full and empty percentages of the threads using the buffer are logged in the event area at the bottom of the Workflow Monitor. For information on how to interpret the results, see the section below, Analyzing Thread Buffer Statistics. |
A UDR may be queued up while another thread is busy processing a reference to it. Workflows routing the same UDR on several routes and involving further processing of its data, must consequently be reconfigured to avoid this. A simple workaround is to route the UDR to an Analysis agent for cloning before routing it to the other agents (one unique clone per route).
Analyzing Thread Buffer Statistics
By using the Print Statistics alternative in the Thread Buffer tab, buffer statistics are logged for the whole batch execution and show the full and empty percentages for the threads using the thread buffer. For information about multithreading in a batch workflow, refer to the section Threads in a Batch Workflow, in Multithreading (4.3).

Example - A thread buffer printout
| Eclipse |
11:03:04: Buffer usage statistics [5] for 2089 turnover(s) of UDRs:
Incoming queue: Available 54%. Full 46%.
Outgoing queue: Available 59%. Empty 41%. |
The number within brackets, which is
[5]in the example, is the batch counter id.Turnoveris the total number of UDRs that have passed through the buffer.Availableindicates how often (out of the total turnover time) the buffer has been available for the incoming queue to forward a UDR and for the outgoing queue to fetch a UDR.Incoming queue:Fullis logged for the incoming thread and indicates how often (out of the total turnover time) the buffer has been full and an incoming UDR had to wait for available buffer space.In the example,
Fullindicates that for 46% of the incoming UDRs there was a delay because of a full buffer.Outgoing queue:Emptyis logged for the outgoing thread and indicates how often (out of the total turnover time) an outgoing queue had to wait for data because of an empty buffer.In the example,
Emptyindicates that for 41% of the attempts to fetch a UDR, the buffer was empty.
The percentage values for Empty and Full must be as low as possible, and as equal as possible. The latter may be hard to achieve, since the agents may differ too much in processing complexity. If possible, add and configure another agent to take over some of the processing steps from the most complex agent.
See the section below, Thread Buffer Tab, for how to configure the thread buffer.

Sequence
...
Tab
...
For batch collection agents such as Disk, FTP, and SFTP, there is a service available, found in the agents' configuration configuration dialog in the Filename Sequence tab. The filename sequence is used when you want to collect files that contain a sequence number in the file name. The sequence number is expected to be found at a specific position in the file name and has a fixed or dynamic size.
| Note | |
|---|---|
| title | Note!When collecting from several sources, the Filename Sequence service is applied to the data that arrive from all the sources, as though all the information arrives from a single source. This means that the Filename Sequence number count is not specific to any of the sources. |
...

...
Description | ||
|---|---|---|
Enable Filename Sequence | Determines if the service will be used or not. | |
Start Position | The offset in the file name where the sequence number starts. The first character has offset 0 (zero). In the example file name | |
Length | The length of the sequence number, if the sequence number has a static length (padded with leading zeros). If the sequence number length is dynamic this value is set to 0 (zero).
|
...
| |
Wrap On | If the Filename Sequence service is enabled, a value must be specified on which the sequence will wrap. This number should be larger than or equal to Next Sequence Number and it must be larger than Wrap To. |
Wrap To | The value that the sequence will wrap to. This value must be less than the Wrap On value and less than or equal to Next Sequence Number. |
Warn On Out Of Sequence | If enabled, the agent logs an informative message to the System Log when detecting an out of sequence file, before deactivating. The collection agent will not continue to collect any files upon the next activation, until either the missing file is found, or the Next Sequence Number is set to |

a valid value. |
Sort Order Tab
The Sort Order service is available for some batch collection agents and is used to sort matched files before collection.
The sort pattern is expected to occur at a specific position in the file name or to be located using a regular expression. However, if the sort pattern cannot be applied, the workflow will abort, except for files with a name which is shorter than Position plus Length. For information on this exception, see the description below for Position.

This could be either Position that indicates that the item is located at a fixed position in the file name or Regular Expression indicating that the item should be fetched using a regular expression. | |
Position | If Position is enabled, the files are sorted based on the part of the filename indicated by Position plus Length. The Start Position value states the offset in the file name where the sorting item starts. The first character has offset 0 (zero). The Length value states the length of the sorting item (part of the file name) if it has a static length. To sort items with a dynamic length, use the value zero (0).

Tab
...
The Filename Template service is available to batch forwarding agents that are responsible for creating a file, and the Disk forwarding agent for real-time workflows. The configuration contains MIM resources for all available agents in the workflow, the values of which may be used when constructing a filename for the outgoing file.
Since this service includes a selection of MIM resources from available agents in the workflow, it is advised to add all agents to the workflow, and to assign route and agent names, before the filename template configuration is completed.
| Note |
|---|
Note!The Filename Template service also provides you with the so called Dynamic Directory support. This means that you can change the output directory during execution of a workflow, the input data of which is bytearray. See Input Data in the configuration Target tab of your relevant forwarding agent. By creating directories and subdirectories with names which consist of MIM values, and by adding appropriate APL code, you configure the output directory to sort the out data into directories that are created during the workflow execution. For further information, see the section below, Defining a MIM Resource of FNTUDR Type. |
...

MIM Defined | Determines if the |
Value will be selected from a MIM resource. The MIM resource of type FNTUDR is represented in the template table in the same way as other MIMs, however it has an other appearance when the filename or filepath is presented. A MIM FNTUDR value can represent a sub-path with delimiters, a part of a filename, or a directory. For further information about how to use the FNTUDR in filename templates, see the section below, Defining a MIM Resource of FNTUDR Type. | |
User Defined | Determines if the |
Value will be a user defined constant entered in the text field. | |
Directory Delimiter | Determines if the Value will be a directory delimiter indicating that the file sub-path will have a directory delimiter at that specified position. You cannot have two directory delimiters directly after each other, or a delimiter in the beginning or end of a filename template. The MIM resource of the special UDR type FNTUDR can include, begin or/and end with directory delimiters this must be noted when adding delimiters in the template. For further information about using the FNTUDR in filename templates, see the section below, Defining a MIM Resource of FNTUDR Type. |
Size | Number of allocated characters in the file name for the selected MIM resource (or user defined constant). If the actual value is smaller than this number, the remaining space will be padded with the chosen padding character. If left empty, the number of characters allocated in the file name will be equal to the MIM value or the constant. |
Padding | Character to pad remaining space with if Size is set. If Size is not set, this value is ignored. |
Alignment | Left or right alignment within the allocated size. If Size is not set, this value is ignored. |
Separator | Separating character to add to the file name after the MIM value or constant. |
Date Format | Adds a timestamp to the file name in the selected way. For further information about the format, see Date and Time Format Codes in Administration and Management( |
4.3). |

Defining a MIM Resource of FNTUDR Type
A MIM resource with a value of the FNTUDR type included in the filename template is treated somewhat differently than other MIM resources. A FNTUDR value is a text string that can contain delimiters. The delimiters in the FNTUDR value will be replaced by directory delimiters when determining the target file path. The FNTUDR is defined in the FNT folder.
| Info | |||||
|---|---|---|---|---|---|
| title | Example - How to create an FNTUDR value to publishe as a MIM resourceThe following example shows a set of APL code that creates a FNTUDR value and publishes it as a MIM resource. To use the FNTUDR value in a filename template, the MIM resource must be added in the filename template configuration.
| ||||
| theme | Eclipse |
import ultra.FNT;
mimPublish( global, "FNTUDR Value" , any );
consume {
FNTUDR fntudr = udrCreate(FNTUDR);
fntAddString(fntudr, "dir");
fntAddString(fntudr, "1");
fntAddDirDelimiter(fntudr);
fntAddString(fntudr, "dir2");
fntAddDirDelimiter(fntudr);
fntAddString(fntudr, "partOfFileName");
mimSet ("FNTUDR Value", fntudr);
udrRoute(input);
} |
The following filename template configuration uses the FNTUDR published by the APL code.
The resulting output file in the previous example is saved in a file with the following sub path from the root directory.
| Code Block | ||
|---|---|---|
|
dir0/dir1/dir2/partOfFileName20070101_1 |
The part dir1/dir2/partOfFileName derives from the FNTUDR Value.
For further information about how to manipulate FNTUDRs with APL functions and how to publish MIM resources, see the APL Reference Guide(34.3) and the section Meta Information Model in Administration and Management(34.3).
