| There is a requirement in my project that we need to know get the statistics of all jcl,cobol and db2 libraries like no.of members in each library,member list,no.of lines in each member,total no.of lines in each pds and also size of each member and pds. Can we get all this info using fileaid/ispd/tso or any jcl utilities? Please suggest. |

| Well, that is only 3 PDSes per person - it won't take long for each person to do it manually - certainly much quicker than posting here, waiting for an answer and then doing it manually anyway. |

I suspect the simple answer is no. You can get most of this information from different sources easy enough but would have to combine it. Someone with good rexx skills may be able to provide something.
The only way I know of is if you have FDR (therefore FDREPORT), this will give you what you need. Although the PDS size info etc is repeated for every member, the relevent individual member information is reported for each one. (note: the XDSN field allows for dataset name masking much the same as DFDSS or 3.4)
| Code: |
//FDR#PDS EXEC PGM=FDREPORT,REGION=512M
//SYSPRINT DD SYSOUT=*
//ABRMAP DD SYSOUT=*
//ABRSUM DD SYSOUT=*
//SYSIN DD *
REPORT FIELD=(NAME,CAPBYTES,SIZE,DIRBLOCK,MEMBERS,MEMBCURR,
MEMBVER,MEMBSSI,MEMBSTOR,MEMNAME)
XS XDSN=PDS%.NAME.MASK*.**,DSORG=(PO,POE)
SORT FIELD=(NAME,MEMNAME)
PRINT DATATYPE=CATVTOC,SUM=NO,SORT=CO,
ENABLE=(FASTPATH),RPTYPE=TABLE |
If you need further help just run the same JCL but with just XHELP ALL in the SYSIN and it produces a full manual. |

How has this become a "requirement"? If your system uses any kind of change control / configuraton management tool, something like this is usually builtin and is managed by that group - not someone who is a developer.
What actual or percieved benefit will be realized having this? In the 70's and 80's many places implemented their own statistics generators only to realize that they provided little or no value. . .
If your organization insists on doing this, do as suggested and hire/develop the REXX skills needed to do this. Keep in mind that the ISPF statistics are not always correct. Sometimes, they are not even captured. |

Hi Pete,
I am using FDRREPORT to get the required data and am able to get that but I need small clarification. When I submitted the job my output is like below
| Code: |
CKBYTES KBYUSED ALLOC DIRBK MEMBER SIZE VV SSI
849960 446329 15000 7000 35299 12 1
849960 446329 15000 7000 35299 12 1
849960 446329 15000 7000 35299 8 1
849960 446329 15000 7000 35299 8 1
849960 446329 15000 7000 35299 8 1
|
In the baove screenshot, KBYUSED=446329 that means size of the PDS is 446329 kilo bytes? What parameter I need to mention in the SYSIN if I need the size in MB or GB? I used BYTESUSEM and MBYUSED but getting RC12 error, please help. |

Yes the CKBYTES is the size of the whole PDS.
This can be changed by coding BYTEF=MEGA,SUMBYTEF=MEGA on the PRINT statement.
As I said, run the same JCL but with just XHELP ALL in the SYSIN and it produces a full manual |

Hi Pete,
I will use the specified options.
Please correct me if my below understanding is wrong from my screen shot.
CKBYTES -- No.of Kilo Bytes allocated for the PDS
KBYUSED -- No.of Kilo Bytes used by the PDS
And also, Please let me know how to specify multiple PDS names as Input in XS XDSN step. |

Yes, although in my original posting I didn't specify BYTESUSE so not sure why it is being reported. Did you change the SYSIN?
NOW - LOOK CAREFULLY AT THE FOLLOWING STATEMENT:
Run the same JCL but with just XHELP ALL in the SYSIN and it produces a full manual in the SYSPRINT.
In the manual look for XDSN=. If you read my original post FULLY you would have seen this '(note: the XDSN field allows for dataset name masking much the same as DFDSS or 3.4)'
RTFM - YFW |

I Did 'XHELP ALL' and got the details, based onthe details I have modified my DSN to get the used space in bytes.
I have observed below thing, I have taken one COBOL library which has 4 memebers in it. I got below statistics when I run the FDRREPORT
| Code: |
CKBYTES KBYUSED
21249 782
21249 782
21249 782
21249 782 |
I mentioned CAPBYTES,BYTESUSE in the SYSIN.
That means the space consumed by COBOL library is 782 Kilo bytes.
Now, I have downloaded 4 members to my PC and checked the total size,it's showing 170 KB.
I am getting confused with these SPACE parameters in FDRREPORT. What should I mention in the SYSIN if I should get 170 KB in FDRREPORT as well.

pullaiah.cts,
Please use the Code tags every time that they are appropriate.
Did you read Dick's post? Not just written for fun, you know.
When you "download to your PC" don't you think that dropping trailing blanks may be an effect on the program size? The more short and meaningless the data-names, the more trailing space there is. However, the amount of space physically occupied by Cobol source means, to you, what? Back to Dick's points. |

If you rip the lungs out of a human being (something I occasionally would like to do) they are no longer the same as they were being part of a whole human being.
That is what it is like comparing the member contents stored on the PC with the whole PDS structure and member content on ZOS.
If you look at the report value under the SIZE heading for each of the 4 members, what does that add up to? |

Sorry Bill, I didn't realize that there wil be a difference between Z/os and PC statistics.
I will do some manual work at PC side to get the actual size.
Thank you all for your help and suggestions. |

I still don't get how the size of a Cobol source is going to be related to anything.
With dumb data-names and shoddy layout, I guess you might get a program with 40 characters or fewer per line. Mine would be above 70, likely.
Measure away, but what are you trying to measure? And why? |

How much "stuff" we have - as often demonstrated, not a valueable "thing to have".
Because someone who doesn't know any better has made this "a requirement". . .
