DFSDSCTy member of the IMS PROCLIB data set
Use the DFSDSCTy member of the IMS PROCLIB data set to specify override descriptors for the Extended Terminal Option (ETO), including logon descriptors, MFS device descriptors, MSC descriptors, and user descriptors.
The descriptors that you can specify in the DFSDSCTy member, as well as the syntax and parameters of those descriptors, are exactly the same as the descriptors that you can specify in the DFSDSCMx member. However, if a descriptor is specified on both members, the specifications coded in the DFSDSCTy member for the descriptor override the specifications coded in the DFSDSCMx member.
- Logon descriptors
- MFS device descriptors
- MSC descriptors
- User descriptors
To use IMS ETO Support,
at least one user descriptor and one logon descriptor must exist in
either the DFSDSCMx or the DFSDSCTy member. If one or both of the
logon and user descriptors do not exist when you enable IMS ETO Support, IMS abends
with U0015 issuing message DFS3652.
By default, the suffix y on DFSDSCTy is 0. You can define a different value as the suffix by specifying the value on the DSCT= parameter in the IMS or DCC startup procedures.
The syntax and parameters of the ETO descriptors are documented under DFSDSCMx member of the IMS PROCLIB data set
