Intra-CPC block-level data sharing

An example of intra-CPC block-level data sharing, including IMS and PSB definition statements, is provided.

Figure 1 shows a possible configuration for data sharing.

MVSA comprises IRLM A and IMS A (MPP BMP IFP with update access). MVS B comprises IRLM B and IMS B (same as IMS A) and IMS C (DL/I batch with update access). All IMS systems share SHRDB.

System A

IMS system definition statements include:

  • IMSCTRL IMSID=IMSA,IRLMNM=RLMA
  • DATABASE DBD=SHRDB,ACCESS=RD

PSB definition statements include:

  • PCB TYPE=DB,DBDNAME=SHRDB,PROCOPT=A

System B

IMS system definition statements include:

  • IMSCTRL IMSID=IMSB,IRLMNM=RLMA,SYSTEM=(VS2,BATCH)

PSB definition statements include:

  • PCB TYPE=DB,DBDNAME=SHRDB,PROCOPT=GO

System C

IMS system definition statements include:

  • IMSCTRL IMSID=IMSC,SYSTEM=(VS2,BATCH)

PSB definition statements include:

  • PCB TYPE=DB,DBDNAME=SHRDB,PROCOPT=A
