    What is the DELTA PLUS XREF Feature?


    ANSWER:

     

    What is the DELTA PLUS XREF Feature?

      
       
       The DELTA PLUS XREF feature provides information about the defined relationships between IMS system resources. Maintaining this information without DELTA PLUS is a time-consuming manual process. With the DELTA PLUS XREF feature, this information is always current and is available through online displays and batch reports. The DELTA PLUS XREF batch reports include  
        
        
    •  

      a report for a program of all databases that are referenced, explicitly or implicitly, by that program

    •   
    •  

      a report sorted by database of all programs that reference each database

    •   
    •  

      a report sorted by database of all programs that logically (or as an index) reference each database, or any databases that are related to that database

    •   
    •  

      a report sorted by database of the AREAs that are referenced by each database (DEDBs only)

    •   
    •  

      a report for a randomizer of all databases that use the randomizer routine

    •   
    •  

      a report for a compression routine of all databases that use the compression routine

    •   
    •  

      a report for a transaction of all databases that are used by that transaction

    •   
    •  

      a report for a database of all transactions that use the database

    •  
       

    IMS system programmers and DBAs can use the DELTA PLUS XREF feature to facilitate the administration of IMS systems by keeping an inventory of the IMS environment. In the event of recovery situations, such as a broken database, it allows the user to determine everything that will be affected when the broken database is taken offline. The user can display the IMS components and verify the effect of the changes.

       

    This feature can also be executed in batch.
     

       

    The following sample command will display the databases that reference the named randomizer:

       

    /DIS DLP XREF RAND DFSHDC40

       

    The following sample output should display:

       
    RANDNAME - DMBS THAT USE THE RANDOMIZER  DFSHDC40 - DBFSAMD4    IVPDB2  *99084/125316* 
       

    The following sample command will display the PSBs that reference the named database:

       

    /DIS DLP XREF DB DI21PART RELPSB

       

    The following sample output should display:

       
    DMB NAME - PSBS THAT REFERENCE THE DMB  DI21PART - BMPAOI2     BMP002      BMP004      DFHSAM04   DFHSAM05    DFHSAM14    DFHSAM15    DFHSAM24   DFHSAM25    DFSSAM01    DFSSAM02    DFSSAM03   DFSSAM04    DFSSAM05    DFSSAM06    DFSSAM07   DFSSAM08    DFSSAM09    QCONV2      TESTWTOR  *99084/130604*
       

    The following sample command will display the referenced databases for the named PSB:

       

    /DIS DLP XREF PSB DFSSAM02 RELDMB

       

    The following sample output should display:

       
    PSB NAME - REFERENCED DMBS  DFSSAM02 - DI21PART  *99084/131100* 
       

    The following sample command will display the databases used by the named TRAN:

       

    /DIS DLP XREF TRAN PART RELDMB

       

    The following sample output should display:

       
    TRANNAME - DMBS USED BY TRANSACTION PART - DI21PART  *99084/131100*
       

    The following sample command will display the TRANs that use the named database:

       

    /DIS DLP XREF DB DI21PART RELTRAN

       

    The following sample output should display:

       
    DMB NAME - TRANSACTIONS THAT USE THE DATABASE  DI21PART - PART        DSPINV      ADDINV         *99084/130604*
