Finding more information on modules, control blocks, and record formats
You can find the module directory, IMS control block DSECTs, and the log record formats on Service Link. Contact your systems engineer for further information on accessing Service Link.
Control block linkage
The IMS.ACBLIB is a partitioned data set whose members are pre-system-generated, expanded PSB and DMB control blocks. You can view the formats of these control blocks by assembling the database DSECT and CSECT control blocks macro IDLI. You can also find the layout of IMS.ACBLIB members in the ACBGEN module, DFSUACB0, and the Write-PSBs-and-DMBs-to-ACBLIB module, DFSUAMB0.
The following figure provides an overview of the linkage between the major control blocks used for diagnosis.
