3              Information about CEE640PA

With the delivered software updates, a Comarch ERP Enterprise system that has a version from CEE630PB-Fix06 up to CEE630PB-Fix11 will be upgraded to CEE640PA. Versions older than CEE630PB-Fix06 are not supported for an upgrade as well as versions newer than CEE630PB-Fix11. Versions newer than CEE630PB-Fix11 need a newer 6.4 release for the release change which will be available in the future.

3.1        Installing support deliveries

The following sections describe the special features for installing the support deliveries of this delivery.

If the source system has a state that is between CEE630PB-Fix06 and CEE630PB-Fix11, you can use the manual update procedures described below to upgrade a Comarch ERP Enterprise based system to CEE640PA.

Further information is provided in INF-000155.

To install the support deliveries, please use the documentations “Introduction: Software Logistics” and “Using Tools and Troubleshooting Help.”

3.1.1    Cumulative installation of support deliveries

Code status CEE630PB-Fix06 is required for the release upgrade. It is not possible to install Comarch ERP Enterprise 6.3 and Comarch ERP Enterprise 6.4 at the same time. Support deliveries for Comarch ERP Enterprise 6.4 can be installed cumulatively. Further information about the cumulative installation are provided in INF-000228.

3.1.2    Problems during the installation

If a problem arises during the installtion of support deliveries, you can refer to INF-000155 “Behebung von Installations-Problemen von Supportauslieferun­gen” which contains information about possible causes and about instructions on how to solve the problem.

3.2        Installation prerequisites

3.2.1    Upgrade system to CEE630PB-Fix06

Upgrade your Comarch ERP Enterprise system to CEE630PB-Fix06. A release change from older releases is not supported.

3.2.2    Execute all data updates

All data updates have to be executed, so that no data update is in a non-successful state. Otherwise, a release change will not be possible. The release change mechanism will check for this condition.

If there are data updates, which cannot be executed successfully, please create a support request in the Comarch ERP Enterprise support center.

3.2.3    Activate all development tasks and export all software updates

You need to activate all development tasks in the development system before installing this release.

Furthermore, you have to export all software updates. Otherwise, these software updates will be exported as Comarch ERP Enterprise 6.4 software updates and cannot be installed on remaining Comarch ERP Enterprise 6.3 systems.

3.2.4    Compare BIS data model

Use this feature to compare the BIS data model. It is implemented as a before and after comparison.

3.2.5    Import and activate Comarch ERP Enterprise 6.4 licence

You have to import and activate a Comarch ERP Enterprise 6.4 licence for your system before you can install the support deliveries of CEE640PA.

You can request the needed licence in the Comarch ERP Enterprise support center. In the request, please name the system that you want to upgrade to CEE640PA.

3.2.6    Download and install Archive630.dat

You have to download Archive630.dat from INF-002737 and put it into the directory “semiramis\refreshes” of the Comarch ERP Enterprise system you want to upgrade. If this file is already present in this directory, then overwrite the existing file. Archive630.dat includes all the needed development objects and their versions which are required for a release change to Comarch ERP Enterprise 6.4. This file is needed for the release change check mechanism.

3.2.7    Install JDK 11

Comarch ERP Enterprise 6.4 requires JDK 11 as application server runtime environment. A supported JDK vendor is AdoptOpenJDK (www.adoptopenjdk.net). More information is provided in support delivery “INF-002457”.

To use the newly installed version, change the start scripts and/or the OS service configuration files accordingly and restart the system.

3.3        Installation

3.3.1    Remove patches

First, you have to remove the patches from the Comarch ERP Enterprise system. In most cases, these can be found in the directory “semiramis\patch”. If this directory is not available, then there should be no patches installed in your system.

3.3.2    Release change check

Use the following command in the tool shell of an SAS of the Comarch ERP Enterprise system:

chkrlschg –check

The message server checks if all needed software updates of the current release have been installed and if all data updates have been executed successfully. To check these conditions, it uses the information in “semiramis\refreshes\Archive630.dat”. If the command runs successfully, it generates the file “semiramis\refreshes\ReleaseChange630.dat” which allows continuing in the release change process. If a software update is missing, an error message such as the following is output:

ERROR: missing code refresh babel-6.3.0-app-RFR-016423

You have to install the missing software updates and repeat the release change check. In case of problems, create a support request in the Comarch ERP Enterprise support center.

3.3.3    JVM parameters for upgrade

Make sure to configure enough “heap” memory for the JVM of the message server. Following parameters have been used for release changes to CEE640PA for the JVM:

-server -Xmx3000m -Xms3000m

3.3.4    Provide software updates

Copy all software updates of CEE640PA to the directory “semiramis\refreshes\import”.

A cumulative upgrade to Comarch ERP Enterprise 6.4 is suggested. See INF-000228 for more information.

3.3.5    Install remaining code refreshes

For the installation you can use command:

insrfr –codeclass:sys –codeclass:app –installType:3

When successful, all refreshes have been installed and the upgrade to CEE640PA is finished.

3.4        Rework after installation

3.4.1    Work on development objects

It is very likely that a conflict job has been generated during the upgrade to Comarch ERP Enterprise 6.4 on a development system. You need to work on this conflict job to finish the release process on a development system.

3.4.2    Data updates

Data updates have been carried out automatically in the release upgrade process. You have to check the installation protocol for all applied data updates.

3.4.3    Batch data updates

With the “Query data updates” application, you must schedule all the required batch data updates, for any point in time. It is advised to execute these data updates as early as possible after the release upgrade.

3.4.4    Language refreshes

You should install the language refreshes for all your licensed languages to have up-to-date texts. Download the LNG support deliveries for release Comarch ERP Enterprise 6.4 and install them with the tool shell command “inslng –languages”.

3.4.5    Remove superfluous tables

To remove old tables from the database, which are not needed anymore by the Comarch ERP Enterprise system, carry out the following command in the tool shell of an SAS:

dltdbt -table:% -olap -oltp –repository

3.4.6    Check consistency

To check if all the business objects have the correct schema and no index is missing, carry out the following command in the tool shell of an SAS:

chkdbt -analyseTables -all -table:% -olap -oltp –repository

3.4.7    Update database statistics

Because of large changes during the upgrade process, it is suggested to update the statistics for the databases used by the Comarch ERP Enterprise system. Otherwise, a bad performance impact is very likely.

3.4.8    Check individual indexes

Check all the individual indexes on your Comarch ERP Enterprise system if every index is still active. Use the “Individual indexes” application. Sometimes indexes have been integrated into the standard and therefore the individual index is not needed anymore, or the schema has been changed in a way that the index cannot be applied anymore.

Use the application “Individual indexes” to manage individual indexes (creation, deletion, etc.). Otherwise, the index will be dropped in many cases, when the related business object is updated.

3.4.9    Update adapters

You should update the used adapters to the newest version available. Check if the used adapters are ready for usage with Comarch ERP Enterprise 6.2. You can check for available adapters in the Comarch ERP Enterprise support center, searching by type “900”.

3.4.10       Install latest SOM

You should install the latest ERP System Output Manager (SOM) available to reduce the probability of experiencing already fixed bugs. You can download the latest version from the Comarch ERP Enterprise support center.

3.4.11       Install ODBC client

Install the ODBC client delivered by the Comarch ERP Enterprise 6.4 system.

3.4.12       Check reports

You should check whether there have been relevant changes in the business objects used in the reports that you use. If necessary, adapt the reports to these changes.
