Listing Files Details from Data Store

[abaruchi]

Hi guys,

I need to develop a tool to keep tracking the existence of files in OS level and also in DFU. In order to list files from data store Im using the dfuplus command as following:

Code: Select all

dfuplus action=list name=* server=http://<ecl_watch:8010> username=<myuser> password=<mypass>


The command executes fine, however, in my configuration I have four cluster being managed by the same ECL Watch and I would like to gather more details of these files, at least, in which cluster they are stored. Does somebody know a command or another parameter to get this kind of information?

Thanks in advance.

Att.

Artur,

You can use ECL code to do this, too. The Standard Library has a GetLogicalFileAttribute() function that gets all the attributes of any file. The one you're interested in is this:

Code: Select all

STD.File.GetLogicalFileAttribute(filename,'clusterName')

Here's a function I wrote using that function to return all the attributes of any set of files:

Code: Select all

IMPORT STD;
GetLogicalFileAllAttributes(SET OF STRING files) := FUNCTION
  rec := RECORD
      STRING filename;
      STRING recordSize;
      STRING recordCount;
      STRING size;
      STRING clusterName;
      STRING directory;
      STRING numparts;
      STRING owner;
      STRING description;
      STRING partmask;
      STRING name;
      STRING modified;
      STRING protected;
      STRING format;
      STRING job;
      STRING checkSum;
      STRING kind;
      STRING csvSeparate;
      STRING csvTerminate;
      STRING csvEscape;
      STRING headerLength;
      STRING footerLength;
      STRING rowtag;
      STRING workunit;
      STRING accessed;
      STRING expireDays;
      STRING maxRecordSize;
      STRING csvQuote;
      STRING blockCompressed;
      STRING compressedSize;
      STRING fileCrc;
      STRING formatCrc;
      STRING ECL;
   END;

  ds := DATASET(files,{STRING file});

  RetDS := NOTHOR(
    PROJECT(ds,TRANSFORM(rec,
      ThisFile := '~' + LEFT.file;
      GetAttr(STRING attr) :=
        STD.File.GetLogicalFileAttribute(ThisFile,
                                         attr);
      SELF.filename := LEFT.file;
      SELF.recordSize := GetAttr('recordSize');
      SELF.recordCount := GetAttr('recordCount');
      SELF.size := GetAttr('size');
      SELF.clusterName := GetAttr('clusterName');
      SELF.directory := GetAttr('directory');
      SELF.numparts := GetAttr('numparts');
      SELF.owner := GetAttr('owner');
      SELF.description := GetAttr('description');
      SELF.partmask := GetAttr('partmask');
      SELF.name := GetAttr('name');
      SELF.modified := GetAttr('modified');
      SELF.protected := GetAttr('protected');
      SELF.format := GetAttr('format');
      SELF.job := GetAttr('job');
      SELF.checkSum := GetAttr('checkSum');
      SELF.kind := GetAttr('kind');
      SELF.csvSeparate := GetAttr('csvSeparate');
      SELF.csvTerminate := GetAttr('csvTerminate');
      SELF.csvEscape := GetAttr('csvEscape');
      SELF.headerLength := GetAttr('headerLength');
      SELF.footerLength := GetAttr('footerLength');
      SELF.rowtag := GetAttr('rowtag');
      SELF.workunit := GetAttr('workunit');
      SELF.accessed := GetAttr('accessed');
      SELF.expireDays := GetAttr('expireDays');
      SELF.maxRecordSize := GetAttr('maxRecordSize');
      SELF.csvQuote := GetAttr('csvQuote');
      SELF.blockCompressed := GetAttr('blockCompressed');
      SELF.compressedSize := GetAttr('compressedSize');
      SELF.fileCrc := GetAttr('fileCrc');
      SELF.formatCrc := GetAttr('formatCrc');
      SELF.ECL := GetAttr('ECL'))));
  RETURN RetDS;
END;   

filelist := NOTHOR(STD.File.LogicalFileList());
// MyFiles := filelist(owner='rtaylor' and name[1..5]='class');
MyFiles := filelist(Std.Str.find(name,'lookupcsz',1)<>0);

GetLogicalFileAllAttributes(SET(MyFiles,name));

I'm using NOTHOR because this is only working with the DFU's metadata so there's no need to run on Thor. I'm also using the STD.File.LogicalFileList() function to get all the filenames, then filtering that result to get just the files I'm interested in.

HTH,
