Downloading DBDs for IMS change data capture

Follow the instructions outlined that follow to download the DBDs for IMS change data capture.

About this task

The IMS Remote Source container requires a binary version of the Database Description (DBD) to be present in the DBDLIB directory. The DBD here is used to process a CREATE TABLE or ALTER statements, along with referencing an active table mapping for a subscription when replication is enabled. The container does not verify that the DBD it loads is consistent with the DBD referenced by the IMS Remote Source log reader, or the one used by IMS.

1. Use FTP/SFTP to binary transfer the DBD from z/OS to the Linux® host system. The z/OS location depends on your site’s configuration:

   ftp> cd 'IMSVS.IMD1.DBDLIB'
   250-The working directory may be a load library 
   250 The working directory "IMSVS.IMD1.DBDLIB" is a partitioned data set
   ftp> bin                                                                                       
   200 Representation type is Image                                                               
   ftp> get L3FPDB08
   

2. Copy the DBD into the IMS Remote Source container’s DBDLIB directory:

   podman cp L3FPDB08 ClassicCDCIMS:/classic/shell/DBDLIB
