Installing a group - IBM - AS/400

Installing a group is achieved in one of the following ways:

  • Using the ADDCICSGLT command
  • Using the INSCICSGRP CL command
  • Using the CEDA Install group function

Using the ADDCICSGLT command
Using the ADDCICSGLT command to include a group in a group list table and entering the group name in the INSGRP parameter. The group will then be installed, with the other groups in the GLT, at control region initialization.

The SITLIB and SITGRP parameters of the STRCICS command determine which SIT is used at control region initialization. The SIT parameters GLTLIB and GLTGRP name the GLT to be used. All the resource definition groups named in the GLT are installed for the control region.

Note: Remember that if you want to install the resources defined in the group specified in the GLTGRP parameter, you must include that group in its own GLT.

Using the INSCICSGRP command
The INSCICSGRP CL command is used to install resources dynamically for an already-active control region. Unlike automatic resource installation at control region startup, dynamic resource installation is limited to the installation of a single resource group. The INSCICSGRP CL command, which is run as an OS/400 batch job, installs a resource definition group into the control region named in the CTLRGN parameter.

You can install dynamically both new and amended resource definition entries forthe following tables:

  • Conversion vector table
  • Program control table
  • Processing program table
  • Terminal control system table
  • Terminal control table

You may install a maximum of 200 amended entries of each of these table types; there is no limit to the number of new table entries. All the entries must be in the same group.

The group is not installed if any resource in the group is being used; for example,if a terminal referred to by a TCT entry has an ACQUIRED status, or if a transaction referred to by a PCT entry is being used by someone on the system. You should take care that the terminal you are using is not included in the group you are installing. If it is, the installation will fail. You can install new entries, but not amended entries, for the following tables:

  • Destination control table
  • File control table
  • Journal control table

(To install amended entries for a file control table, you could use CEMT to disable and then discard the file entries.)
The INSCICSGRP CL command ignores the following tables in the group:

  • Group list table
  • System initialization table
  • Temporary storage table

If the CONVERT parameter of the STRCICS command has been set to *PROMPT, you will be asked to specify whether or not you want any previous-release resource-definition files to be converted to the current release.

Using the CEDA Install group function
The Install group function of the CEDA transaction is used to install resources dynamically for an already-active control region. Unlike automatic resource installation at control region startup, dynamic resource installation is limited to the installation of a single resource group. The Install group function of the CEDA transaction may be used in one of the following ways:

  • Fill in the options on the CEDA panel and press F13.
  • Start a user shell using the STRCICSUSR command. When the screen clears, type:
  • CEDA INSTALL library group
    where library is the name of the OS/400 library in which the group exists, and group is the name of the resource definition group to be installed.

  • From the command line, enter a command of the form:

STRCICSUSR CTLRGN(name) TRANID(CEDA) DATA(’INSTALL library group’)
For details about the form of the STRCICSUSR command.
You can install dynamically new and amended resource definition entries for the following tables:

  • Conversion vector table
  • Program control table
  • Processing program table
  • Terminal control system table
  • Terminal control table

You may install a maximum of 200 amended entries for each of these table types; there is no limit to the number of new entries. All the entries must belong to the same group.

The group is not installed if any resource in the group is being used; for example, if the terminal referred to by a TCT entry has an ACQUIRED status, or if a transaction referred to by a PCT entry is being used by someone on the system. You should take care that the terminal you are using is not included in the group you are installing. If it is, the installation will fail. You may install new entries, but not amended entries, for the following tables:

  • Destination control table
  • File control table
  • Journal control table

(To install amended entries for a file control table, you could use CEMT to disable and then discard the file entries.)
The Install group function of CEDA ignores the following tables in the group:

  • Group list table
  • System initialization table
  • Temporary storage table

If the CONVERT parameter of the STRCICS command has been set to *PROMPT, you will be asked to specify whether or not you want any previous-release resource-definition files to be converted to the current release.

Successful completion of the CEDA Install group function results in the installation into the control region (being used by the user shell) of the group referred to in the CEDA transaction.

Note: CEDA is available only if you have defined the supplied transaction group AEGSPI.
