IMS/DC Cross-Memory Notes

Be aware of the following:

The primary RMOXMS region is to be started with the XMSSUB=YES parameter.
This region can be in a separate XMS address space or share the address space with XMS or VTAM sessions.
The XMSSUB=YES parameter must only be used in an XMS address space with a default subsystem ID (SUBSYS=XMC0 or not specified).
If multiple RMOXMS regions are started, they must be started with XMSSUB=NO parameter.
Only the primary XMS region can have XMSSUB=YES specified.
The XMS regions must have the XMS=YES parameter to make it accessible.
The EBCXMCTR table must be assembled during installation to define the relationship between CA View and CA Deliver database high-level qualifiers. The table contains an EBCXMOPT macro to define initialization options and the EBCXMTRN macro for each CICS user transaction.

The EBCXMTRN macro also contains options for the specific database:

SUBSYS= parameter of the cross-memory task.
The parameter must match the SUBSYS= parameter specified in the EBCXMCTR table entry.
RECON=YES can be used to allow reconnection (after an ISPF terminal error) at the point of exit.
TIMEOUT= specifies how long ISPF is to wait for the XMS session to respond after the user enters input, in seconds.
We recommend a value as high as possible but not less than 240 (4 minutes).

To abort the XMS session and return the user to ISPF or the TSO command prompt, press the ATTN key.

Note: The SUBMAX= parameter controls the number of user connections, not the USERMAX= parameter. USERMAX=only applies when you are using the subtask with the CICS interface.

To control screen size manually, use these operands. The SNA query command can also be used to determine the device characteristics.
