This article discusses how to concatenate daily RXX tapes together to create a weekly RXX tape so that it still be used for Recovery processing, READRXX, and REPORT RXX.

The process to concatenate multiple RXX files into a single file is not really different from using multiple concatenated files under the RXX DD statement with the DBUTLTY Recovery or reporting functions.

As a result, any normal utility to copy and concatenate standard sequential files can be used to create a single, combined RXX file - for example, IEBGENER, CA File Master, IDCAMS Repro (note that you need to specify the DCB information for this), or other copy utilities.

Be sure to test that the concatenated file works as expected before deleting the original source RXX files.

On a side note, if you are planning to consolidate all the versions of a GDS into a single file, you can specify only a single DD statement using the GDG base, and you will want to be sure to specify GDGORDER=FIFO. Here is an example with IEBGENER:

//GENER    EXEC  PGM=IEBGENER,REGION=0M                                
//SYSIN    DD  DUMMY                                                   
//SYSPRINT DD  SYSOUT=*                                                
//             UNIT=(3390,10),SPACE=(CYL,(1000,100),RLSE),BUFNO=100
