Terminate workspace if a reader doesn't contain any features?

I'm relatively new to FME and love it so far but need a little guidance. I'm developing workspaces using a custom reader that reads an object oriented file. I never know what features I'm going to receive in the file and want to add some error handling in the begining of the process by testing to see if any features exist - if not, terminate. I've tried adding a counter and a terminator to the reader but no features exist so I never get a number from the counter. The workbench continues running since I have other readers (that do have features). How do I terminate the workspace if a certain reader doesn't contain any features?

Set Dataset in FeatureReader from feature attribute

Hi all I have a workspace where I'm using information from one set of features (municipalities) to define other datasets to read (f.i. road fences). Each feature has an attribute with the name of the dataset that should be read for this specific feature. For instance: For the feature with municipality number 501, I want to read corresponding features from the dataset K:\\.....\\0501\\...\\VSI20501.GDD, and for the feature with municipality number 522, I want to read corresponding features from the dataset K:\\.....\\0522\\...\\VSI20522.GDD. I have been using a sub workspace and WorkspaceRunner to solve this earlier, sending the path for each dataset as a parameter for the sub workspace. But now I would like to have it all in one workspace, and figured the FeatureReader would be a good sollution. However, it is not possible to set the dataset to read in the FeatureReader from an incoming (INITIATOR) attribute. Could it be possible to set the dataset using a Python script or some

Create directory with Python

Hi, I create a fmw that : 1. create a directoy with the same name of zip file, 2. move the zip file to this directory. this fmw works fine withe if the name of file is note a numeric (like : toto.shp.zip, => OK but with another file that has only numeric name : 1.shp.zip => KO). With FME Desktop it works fine for both cases. If i run it with FME SERVER, there is an error : 54 WARN 0.2 1.3 2013-08-20 10:49:50 Python Exception : [Errno 2] No such file or directory: '\\\\\\\\1.shp.zip' 55 ERROR 0 1.3 2013-08-20 10:49:50 Error encountered while calling function `processFeature' No more details for this error. Any help? Thanks an advance. Farfar

Clip by GPs via Web interface:

I have a public web interface that is inteneded to allow users to extract shapefile data from Oracle SDE via GP key in. I have published parameters and created the interface but I dont know what transformers to use in the workbench to allow the GP clipping. Something about attribute filer I suspect. http://fmeserver.ncd.noaa.gov/encdirect_extract_approach.html

SherbendGeneralizer performance issues

At the moment I am trying to use SherbendGeneralizer to generalize our data set in UK and I have some big performance issues. So I need an expert advice. Here is my workflow. Intersect Line(rivers, approx. 2MB shape file ) and Polygon (Postal code plus Administrative boundaries approx. 55 MB shape file) Perform the SherbendGeneralizer Export generalized layers When I chose a small area then it works fine but when I chose complete country it runs and runs without any output. Even after three days there is not output. I am using FME (Professional Edition) 2013 (Build 13264, WIN32) and FME (Professional Edition) 2013 (Build 13264, WIN64) on Windows 7.

Run oracle procedure via python shutdown script

Hallo all, I need to make sure that my procedures (enabling triggers and constrints) are run at the end of my translation. Since I have no idea if any of my writers will be triggerd I cannot use the end sql. After googling I came across the following module (cx_Oracle), but I dont know how to use it with procedures, or if it is at all possible. Any assistance would be helpful. Itay

Custom transformer - is it feature-based or group-based?

Hello, I am in doubt whether the custom transformer I created processes just one feature at a time. It does not have any "group-by" clause active, but still seems to accumulate all the features first and then process them, instead of processing one by one. Is there a way how to check this behavior? Or better, is there a way how to forcingly make it feature-based instead of group-based? Thank you in anticipation, Jaroslav

Workspace Fails - Data in Mapped Drive uses Spaces in Folder Name

A workspace which reads data from or writes data to a mapped network drive does not run on FME Server. The service works just fine in FME Workbench, but fails on FME Server. Have already tried: - HTML encoding the path - Python escaping the space (replacing each space with "\\t") Cannot rename the directory due to several other software programs referencing the same path; nor can I copy the files elsewhere, we are talking several gigabytes of data that changes all the time. Any tips are appreciated!

Dynamic Schema Output Directory

Hi, I have just started using FME 2012 (previously used FME 2009 on a pretty basic level) and noticed the new Dynamic Schema option. I have tried it, but can't find where my output file is going? I have set the output directory but it is not writing to there... Thanks,

FMe Server Chain Jobs - Data Downloader

Hello, I have been following this guide to chain FME Workbenches in FME Server: http://fmepedia.safe.com/articles/How_To/Chain-Jobs-in-FME-Server but I want to be able to download the resultant files at the end and can't figure out how best to do this. I can register the Controller workbench in the Job Submitter repository and it works fine but putting it in the data download repository has no effect because there is no files to write to at the end as they are in the second chained workbench I use. Thanks, Peter.

custom reader date format loses the time

Datetime again! This time I am having trouble keeping the time in a datetime format in a custom reader with an earthquake feed. (Very topical in NZ today!) I can parse the date easily and export the field as datetime, but when I try to use it in ArcMap only the date part is kept. Debugging so far: I kep the date as a string, saved the feed to a file geodatabase. Converts as expected, then an animated time enabled map works by the hour instead of by the day. Inspected the feed by opeining a custom reader in another workspace. The field in recognised as a datetime type, and the contents is a standard FME date yyyymmddhhmmss. Seems OK. Export to a file geodatabase but have to call it a "date", however this is supposed to mean datetime for anything other than dBase stuff like sh**e files. Yep ,works ok. But the whole point is to be dynamic and use the feed to draw the 'quakes without the static copy. Where is the setting I have got wrong, or maybe a bug? I would put up

Attributes from Old Workbench

I created a workbench previously that read in Garmin waypoint information stored in an AutoCAD DXF file and converted into my GIS with a SQL Server DB. This was before FME had a reader for the Garmin GDB file format. I made a copy of that workbench and modified it to read the GDB file instead of the AutoCAD DXF. Toward the end of the translation sequence I have an AttributeRemover to remove unused attributes, but I noticed that somehow the workbench still has some default AutoCAD attributes floating in there. When I see the list of attributes I can remove, I see about 20 or so AutoCAD related attributes. My question is this: Is there a way to flush or reset the workbench so that it only contains attributes related to the current readers, writers, creaters, etc. or do I need to create the work bench from scratch in order to eliminate all these AutoCAD attributes?

Slow raster processing. Is there a better way?

I'm processing county-wide imagery and for large counties it takes up to 16 hours to produce output. My workflow is as follows: Input(MrSid) - Reproject - Clip to area of interest(up to 80% of county) - Tile (2 by 2) - Output (JP2). Reprojecting, clipping and tiling seems to go fast. If writing to JP2 is the problem then I'm out of luck because that's the format we need. Any tips are greatly appreciated. Thanks.

FME Licensing for parallel processing

Hi Folks, With FME 2012, Safe threw in more restrictive licensing for node-locked (fixed) licenses. No matter how many cores a computer has, the number of instances of FME running is limited by the type of license. My question is twofold: a) Are the limits different between "group by" parallel processing and workbenchRunner parallel processing. b) What are the limits for each of these? They don't seem to be documented anywhere. The most I can find is group-by limits http://evangelism.safe.com/fmeevangelist94/ - and it says they're provisional at that time. Our Oracle Edition seems to be limited to 8 FME workbenchRunners, which is a shame because we have 16 cores purchased explicitly for FME. Thanks. Jonathan

where are my attributes? (AreaOnAreaOverlayer)

Hello, I'm an FME newbie. I have a set of polygons which represent parks. As overlays I have layers of elements that exist within these parks, such as parking lots, ovals, playgrounds. The goal is to produce a new layer that covers that area covered by the parks, but that has many more polygons representing what's in the overlays. I'm pretty sure AreaOnAreaOverlayer is the transformer for the job. But when I select the static schema option, the attributes aren’t being written to the new layer. Not even the _overlaps attribute is being written. And when I ask it to make a List by entering a string in the List Name field, I don't know where this list of attributes is going. Where am I supposed to find this list?! TIA, MvW

Passing parameters between workspaces

Hello I created a workflow that transforms some data. As I have to do the same transformation for various oracle-users, I'm using the workflow-runner in a second workbench. But it's not only the name of the user, that I need to pass to the transformation-workflow, but also a second parameter (an attribute in a table). I read in a post, that I have to concatenate the two values an pass them as one parameter to the other workflow. But how can I integrate that parameter in my workflow? There is a transformer "parameter-fetcher", but it needs input from a reader. I also have to split the parameter again (Attribute-splitter) and use one of the two parameters for my reader (oracle-user) and the other in my writer (attribute). Thanks in advance Vera

Setting a random colour per group - is there a better way?

I want to set feature colours at random according to an attribute value (similar to a thematic map). At the moment I'm achieving this by taking the data, using a duplicateremover so there is one instance of each group, a featurecoloursetter with the color scheme set to random, an attributekeeper to keep only the group attribute and the colour and then a featuremerger to merge the data back with the original data so that all features that share a certain attribute value have the same colour. It seems a bit long winded and I'm wondering if I've missed a better way to acheive this.

JOB ID in Shutdown Python Script

Hi all, Kindly asking for suggestion if anyone had found a solution for such an issue: in theory, getting job_id during python shutdown script execution should be piece of cake, with accessing to FME_MacroValues['FME_JOB_ID'], but actually there is no such key in FME_MacroValues. I've explored all FME_MacroValues dictionary, nothing similar is there. Also, there is nothing that could help in globals() as well. Is actually FME server still providing job_id for python hooks executed on start/end of translation?

Error fetching dynamic schema definitions from reader

I have a workspace with three FeatureReaders (two reading multiple datasets from two different SDE databases) and one reading a single zipped shapefile from a URL. They are all written to a Generic writer with the dynamic schema setting that is getting the schemas from Workspace Resources (Reader as Resource), one for each datasource (FeatureReader). I also have published and private parameters set to allow the user to pick one or more datasets from one or more FeatureReaders to run through the workspace. This works fine for the SDE datasets, but when the zipped shapefile is selected, the translation fails with the following error: UniversalReader -- readSchema resulted in 0 schema features being returned Shape Reader: No Shape files found in specified directory 'C:/Users/cw0157/AppData/Local/Temp/2/HAZ_HW_SITES.zip_1372349846576_4848'.

Setting Dynamic (Oracle) Writer's Feature Type Name?

Hi there, I have one workspace that reads from a Oracle table containing names of source feature types (to read) and target feature types (to write), along with a few other parameters. This workspace passes the name pair to WorkspaceRunner, evoking another workspace that reads the source feature type and wirtes to the target feature type in Oracle. I was able to pass target feature type name as parameter to non-database Writers such as GML Writer, but in the case of Oracle Writer, I could not figure out how this could be accomplished. I think I have done pretty thorough search on various sources including this link http://evangelism.safe.com/fmeevangelist31/ with no avail. But it is possible I may have missed some thing obvious. I appreciate very much any help from the FME community, as always. Bo
