Temp-table Schema Marshal (-ttmarshal)

Use Temp-table Schema Marshal (-ttmarshal) to specify the amount of schema information to marshal for temp-table parameters during an OpenEdge client session (that is, for an ABL client, a single WebSpeed agent, or single AppServer agent). The temp-table may be an independent temp-table or a member of a ProDataSet object.

Operating system and syntax	UNIX / Windows	-ttmarshal n
Use with	Maximum value	Minimum value	Single-user default	Multi-user default
Client Session	—	—	—	—

A value between 0 and 5 representing the amount of schema information to marshal for temp-table parameters. The default value is 0 (which includes all schema information for all temp-table parameters).

The following table lists the possible schema marshaling parameter values.

Value	Description
0	Includes all schema information for all temp-table parameters
1	Minimizes schema information for static temp-table parameters
2	Minimizes schema information for all temp-table parameters
3	Excludes schema information for static temp-table parameters
4	Excludes schema information for all temp-table parameters
5	Excludes schema information for static temp-table parameters and minimizes schema information for dynamic temp-table parameters

You can override this startup parameter setting for an individual temp-table parameter by setting one of the following attributes on the Temp-Table object handle:

SCHEMA-MARSHAL attribute

MIN-SCHEMA-MARSHAL attribute

NO-SCHEMA-MARSHAL attribute

Note: If you specify more than one of these attributes for an individual temp-table, the AVM uses the attribute you most recently specified. The MIN-SCHEMA-MARSHAL and NO-SCHEMA-MARSHAL attributes are supported only for backward compatibility. Use the SCHEMA-MARSHAL attribute instead.

For more information about these attributes, see OpenEdge Development: ABL Reference.
