Specifies the name of the CDRM that controls the CDRSC. The CDRM must be in the same domain as the CDRSC.
If you do not code the CDRM operand, VTAM® sends session setup requests to SSCPs in the default SSCP list, until either the owning SSCP is found or the end of the list is reached. When the owning SSCP is found, VTAM saves the name of the owning SSCP. If the end of the list is reached, the session setup fails.
If you code CDRM, VTAM moves the CDRM name to the top of the default SSCP list, regardless of whether it is included in the list. Session setup requests are then sent to the SSCPs in the default SSCP list until the owning SSCP is found or the end of the list is reached.
If you coded NETID on the NETWORK definition statement, thereby associating it with the CDRSC, and the CDRM name is not the SSCP name of the CDRM in which the resource resides, the session setup could fail. See VFYOWNER for more details.
- The preceding actions affect only the internal copy of the adjacent SSCP table maintained for each CDRSC. They do not affect the actual adjacent SSCP table. When the last session for this resource ends, the CDRM name is reset to the CDRM value specified on the CDRSC definition statement.
- In the SSCP of the originating logical unit (OLU), the CDRM name of the destination logical unit (DLU), if identified, must be correct. If the CDRM name of the DLU is not correct, the operator must issue a MODIFY CDRM command to change the CDRM name.
- You can permanently change the owning CDRM name with the MODIFY CDRM command. See z/OS Communications Server: SNA Operation for more information about the MODIFY CDRM command.
