Multiple Cross-Memory Region Requirements

Be aware of the following:

• All cross‑memory regions started under the same SUBSYS ID are chained together.
• The REGIONID positional parameter is the first value of the PARM= statement for the cross‑memory task.

  You must specify a different REGIONID for each started cross‑memory region.

• The value of the XMSSUB parameter for the primary region depends on the type of XMS region you are defining.

See this table for the XMSSUB values. Specify XMSSUB=NO for all other started regions.

Note:

• You must specify XMS=YES for all other started regions except for VTAM only regions where XMS=NO is permissible.
• Each VTAM cross‑memory region requires a different applid. The applid is specified using the RMOAPPL= parameter.
• Each VTAM cross‑memory region requires VTAMPASS=YES.
• The VTAM administrator must verify that each VTAM cross‑memory applid has this setting:

  AUTH=(PASS,ACO).
