pack_nmemo

The pack_nmemo table stores memo data associated with memo fields in the pack_data table after upgrading to iProcess Engine 11.6.

Since iProcess Engine version 11.6, all the new memo data associated with the memo fields is stored in the VARBINARY(MAX) data type in the pack_nmemo table.

You can migrate case memo data in the pack_memo table to the pack_nmemo table when upgrading to iProcess Engine 11.6 or migrate them by using the swutil MIGRATEMEMOS command after the upgrades.

When a work item is sent out to a queue, memo data is copied from the nmemo table to the pack_nmemo table. The client uses the memo data in the pack_nmemo table to fill out the form correctly. When the form is kept any changed memo data is updated in the pack_nmemo table. When a work item is released memo data is moved from the pack_nmemo table to the nmemo table.

The pack_nmemo table is structured as follows:

TABLE pack_nmemo (
	reqid		NUMERIC(20)		NOT NULL,
	node_id		INTEGER			NOT NULL,
	proc_id		INTEGER			NOT NULL,
	casenum		NUMERIC(20)		NOT NULL,
	memo_id		INTEGER			NOT NULL,
	memo_index	INTEGER			NOT NULL,
	memo_size	INTEGER			NOT NULL,
	memo_data	VARBINARY(MAX)		NOT NULL,
	array_idx	INTEGER			NOT NULL)

Table Activity

The pack_nmemo table contains one row for every assigned memo field that contains data (for example, that has a value other than SW_NA) in every outstanding step on the system.

Rows are added, updated and deleted in the following situations.

A row is...	When...
added	Either: • a step containing memo data is sent out. • a memo field is assigned a value on a keep or release.
updated	An assigned memo field has its data changed on a keep or release.
deleted	any of the following occur: • a release instruction for a work item containing memo data is processed by the background process. • a work item containing memo data is withdrawn. • a case containing memo data is purged.
