Gedeelde geheugengegevens (ttaad4156m000)

Use this session to maintain, per package combination, a list of report objects and/or program objects that must be loaded into shared memory.

This session replaces the already existing Gedeelde geheugengegevens (verouderd) (ttaad4150m000) session, which is now deprecated.

NB

Besides manually adding objects in shared memory, you can use commands in the Beeld, Referenties of Acties menu to import objects from the data dictionary (DD) and from the object measurement data. For details, refer to the descriptions of the form commands.

Migration

As long as no objects are defined as shared memory data in this session, you can migrate the defined objects from the deprecated Gedeelde geheugengegevens (verouderd) (ttaad4150m000) session.

When you start the current ( Gedeelde geheugengegevens (ttaad4156m000)) session, while no objects are defined yet, the following question is displayed:

Do you want to import all objects as defined in session Shared Memory Data (ttaad4150m000)?

If you click Yes, the migration process copies all objects from the deprecated Gedeelde geheugengegevens (verouderd) (ttaad4150m000) session to the current Gedeelde geheugengegevens (ttaad4156m000) session.

NB
  • If the VRC of an object, specified in the deprecated Gedeelde geheugengegevens (verouderd) (ttaad4150m000) session, is directly linked to a package combination (see the Pakketten per pakketcombinatie (ttaad1121m000) session), the object will be linked to this package combination.
  • During a migration ALL data is copied, regardless (if present) allocated memory settings defined in the Toegewezen deel van gedeeld geheugen (ttaad4155m000) session.
  • The data in the deprecated Gedeelde geheugengegevens (verouderd) (ttaad4150m000) session will NOT be deleted.
  • Information on the migration process will be stored in the log.shm_conv logfile in the ${BSE}/log folder.
  • The Beeld, Referenties of Acties menu contains a command to migrate the shared memory data. According to the constraint mentioned above, this option is only enabled as long as no objects are defined as shared memory data in the current Gedeelde geheugengegevens (ttaad4156m000) session.

 

Pakketcombinatie
The package combination to which a list of objects belongs.
NB

Tools objects (objects of packages tt and tl) do not belong to a package combination, and are therefore stored in the dummy <empty> package combination. Therefore, to create a list of Tools objects to be loaded into shared memory, leave this field empty.

Tabeldefinitie in gedeeld geheugen
This check box indicates whether table definitions and domains of a package combination must be loaded into shared memory. This field is technical and functional identical to the Tabeldefinitie in gedeeld geheugen field in the Pakketcombinaties (ttaad1120s000) session.
NB
  • This field is read-only. However, as long as no objects are defined for a package combination, you can change its value in the Pakketcombinaties (ttaad1120s000) session.
  • If one or more objects are defined for a package combination, the check box is automatically selected.
  • You can start the Pakketcombinaties (ttaad1120s000) session through the Beeld, Referenties of Acties menu.
Toegewezen
The amount of memory (in MB), allocated for shared memory data, for a package combination.

To define allocated shared memory, click Toewijzen. The Toegewezen deel van gedeeld geheugen (ttaad4155m000) session starts. Use this session to specify the allocated memory per package combination.

Actueel
The total memory usage (in MB) of all objects, including the objects marked as Vast, in shared memory for a package combination.

If the actual memory usage exceeds the allocated memory, an asterisk (*) symbol is displayed behind the allocated memory.

Vast
The total memory usage (in MB) of all objects marked as Vast in shared memory for a package combination.
Object
The name of the object.

The name has the following format: [package code][module code][object code].

Soort
The type of object: Program Object or Report Object.
Grootte
The estimated size, in bytes, of the object in shared memory.
Vast
If this check box is selected, the object will not be removed from the shared memory data when you run the Objecten vanuit meetwaarden importeren (ttaad4255m000) session with the Vul toegewezen restgeheugen met meest getelde objecten check box selected.

Indien dit selectievakje is uitgeschakeld, the object will be removed from the shared memory data when you run the Objecten vanuit meetwaarden importeren (ttaad4255m000) session with the Vul toegewezen restgeheugen met meest getelde objecten check box selected.

 

Objecten vanuit gedeelde geheugengegevens importeren
Copies the shared memory data from the deprecated Gedeelde geheugengegevens (verouderd) (ttaad4150m000) session to the current Gedeelde geheugengegevens (ttaad4156m000) session.

This option is only enabled as long as no objects are defined as shared memory data in the current session. For details, refer to Migration.

Import Objects from DD
Starts the Objecten vanuit DD importeren (ttaad4254m000) session.
Import Objects from Measurement
Starts the Objecten vanuit meetwaarden importeren (ttaad4255m000) session.
Package Combinations
Starts the Pakketcombinaties (ttaad1120s000) session.
Objectgrootte herberekenen
The object size is stored as shared memory data. However the object size is not a static property. Therefore you can use this command to recalculate the size of the objects in shared memory for a package combination.
Naar runtime converteren
Converts the shared memory data to runtime.

The procedure is identical to the procedure used in the deprecated Gedeelde geheugengegevens (verouderd) (ttaad4150m000) session. However, you can only run the Naar runtime converteren command on a host defined as Master Application Server (MAS) in the Systemen (ttaad0550m000) session. If the host is not a MAS, the Naar runtime converteren command is disabled.

Tools program domains, table definitions and objects (components of packages ‘tl’ and ‘tt’) are not directly related to a package combination. Therefore they are dumped only once, in the package combination that is dumped first.
