ACMS V4.2 ECO2 Kit Description
------------------------------
This ECO kit revises ACMS V4.2 or V4.2-1 to V4.2-2 and can be applied to
ACMS V4.2 development, runtime, and remote kits on both OpenVMX VAX and Alpha.

ECO2 resolves the following problems:

      o Corrects a problem with the ENQLM quota on OpenVMS V7.1 (VAX and
	Alpha) allowing ENQLM to now be set to a virtually unlimited value.

      o Corrects a problem determining the ENQLM value.  The higher of
	the PQL limit or the AUTHORIZE value is used now.

      o Corrects a potential problem with process contention by taking
        the process priority for the ACMS EXC and server processes from
        the application user's SYSUAF.DAT authorization record.

      o Corrects a 10-20 second delay when shutting down the ACMS ACC
        process or exiting from an agent on OpenVMS ALPHA V7.1.

      o Corrects a potential problem causing an access violation when
        linking very large applications with the ADU LINK command.

      o Corrects a potential infinite process loop resulting from an access
        violation (ACCVIO) or a reserved operand fault (ROPRAND) for
        processes linked with ACMSHR.

      o Corrects a problem which could occur when a large number of
	errors occur at the same time.  On Alpha systems, the ACMS_SWL
	process would sometimes abort with an ACCVIO in this situation.


Installation Overview
---------------------
This ECO updates the ACMS V4.2 runtime system by replacing specific
ACMS image files.  The installation procedure will supply the appropriate
VAX or Alpha images for your system environment.  After the ECO is installed,
additional details can be found in the ECO release notes at:

        SYS$HELP:ACMS042_ECO2.RELEASE_NOTES.

This ECO kit is intended for installation on either an OpenVMS VAX V6.2
or an OpenVMS ALPHA V6.2 or higher system.  Installations on other versions
of OpenVMS are not supported and will yield unpredictable results.

Before installing this ECO, the ACMS system must be stopped.  Use the DCL
command: ACMS/STOP SYSTEM.

To install this ECO invoke the VMSINSTALL command procedure, as outlined in
Chapter 3 of the OpenVMS System Manager's Manual.  The installation procedure
will check that ACMS is stopped and that ACMS V4.2 is installed on the system.

After the installation procedure completes, a system reboot is not necessary.
However, prior to restarting ACMS, SYS$STARTUP:ACMSTART must be re-run to
install the updated images.
