2. Upgrading from GemStone/S 64 Bit 3.3.x or later

Previous chapter

Next chapter

This chapter describes how to upgrade an existing GemStone/S 64 Bit 3.3.x, 3.4.x, or 3.5.x installation to GemStone/S 64 Bit version 3.6.

To upgrade from GemStone/S 64 Bit version 3.2.x and earlier, you must first upgrade to a more recent version, and then upgrade to v3.6.

If you are using GemBuilder for Smalltalk (GBS), you also need to upgrade the client libraries that are used by GBS. You may also need to upgrade your version of GBS; versions of GBS earlier than 8.5 or 5.4.6 are not supported with v3.6. See Chapter 4 for details.


Keyfiles for GemStone/S 64 Bit 3.5.x or earlier will not work with v3.6.

To acquire a keyfile for version 3.6, email keyfiles@gemtalksystems.com, or contact GemStone Technical Support, preferably providing your existing keyfile.

Keyfiles also manage access to GemConnect, GemBuilder for Java, and the X509-Secured GemStone feature. If you are using these add-on products, you must use a keyfile with the appropriate permissions.

Upgrade Procedure

The following list summarizes the steps necessary to perform the upgrade to GemStone/S 64 Bit v3.6.

The following instructions use the version number 3.5.4 to refer to the version you are upgrading from, and version number 3.6 indicate the target version you are upgrading to.

Prior to Upgrade in existing application

1. Check for use of deprecated methods

Verify that your application does not invoke any methods that were deprecated in previous releases, by enabling error or logging on deprecation in your existing repository. Deprecated methods are subject to removal in major releases; finding them before upgrading allows the deprecation messages to provide replacement instructions.

For details on finding deprecated methods, refer to the Programming Guide for GemStone/S 64 Bit.

2. File out modifications to GemStone classes

File out any modifications or additions you made to GemStone/S 64 Bit kernel class methods. For more information about fileout, see the GemStone/S 64 Bit Topaz Programming Environment.

You will need to carefully compare these changes with GemStone/S 64 Bit 3.6 kernel methods, and refer to the Release Notes for version 3.6 to determine whether your changes are still necessary or appropriate.

Any changes that you have made to the GemStone/S 64 Bit kernel classes will be lost during upgrade; you MUST file these out in order to preserve the changes in version 3.6.

Prepare for Upgrade

1. Install and configure GemStone/S 64 Bit 3.6

Install GemStone/S 64 Bit 3.6 to a new installation directory, separate from the installation directory for version 3.5.4, as described in Installing GemStone/S 64 Bit Version 3.6.

Configure GemStone/S 64 Bit 3.6 the way you expect to use it — that is, with the appropriate extent locations and sizes.

If you copy the configuration files from your previous version to the version 3.6, be sure to review any changes in configuration parameters to determine if changes are needed.

You should ensure that adequate space is available for extents, transaction logs, and a backup during the upgrade. You must provide space for the extents and transaction logs for both repositories, the old and the new.

2. Reset SystemUser password

Log in to the version 3.5.4 system as a user with OtherPassword privilege, such as DataCurator, and reset the SystemUser password to ‘swordfish’:

topaz 1> printit
(AllUsers userWithId: #SystemUser) password: 'swordfish' .
System commitTransaction.

The upgrade script logs in with the SystemUser account and the default password, and resets the password for DataCurator and GcUser.

3. Stop user activity

Log in to the version 3.5.4 system as a user with SessionAccess and SystemControl privileges, such as DataCurator, and halt all user activity on the repository.

topaz 1> printit
System stopUserSessions.
4. Shut down the repository

You may now shut down the Stone. At the UNIX command line:

> stopstone stone354

where stone354 is the name of the version 3.5.4 stone on this machine. The repository must be cleanly shut down to avoid needing recovery when it is restarted with the new version’s executables.

5. Set up the version 3.6 environment.

Set the environment variables required for the upgrade. For example:

 export GEMSTONE=InstallDir36
 export PATH=$GEMSTONE/bin:$PATH
 export upgradeLogDir=tempDir

where InstallDir36 is the GemStone/S 64 Bit version 3.6 installation and tempDir is a temporary directory for which you have write permission.

6. Copy extent files

Copy your version 3.5.4 extent files into the location specified by the v3.6 configuration file option DBF_EXTENT_NAMES:

a. Identify the complete set of extent files that are used by your 3.5.4 stone. This can be found by examining the configuration file for the version 3.5.4 repository, looking for the last entry for DBF_EXTENT_NAMES.

b. The target location is the setting for DBF_EXTENT_NAMES in the version 3.6 installation. Copy each of these extent files to the target location.

For example:

 cp InstallDir354/data/extent0.dbf InstallDir36/data
 cp InstallDir354/data/extent1.dbf InstallDir36/data
 cp InstallDir354/data/extent2.dbf InstallDir36/data

Before upgrading, ensure that there are no transaction logs from a previous version of GemStone/S 64 Bit in any of the transaction log locations specified in the configuration file that will be used by version 3.6.

Perform the Upgrade

1. Start the Stone

Start the 3.6 Stone on the 3.5.4 extents you just copied:

 startstone stoneName36
2. Upgrade image

Ensure you are in a directory to which you have write permission, and run the upgrade script.

The upgrade is performed by the script upgradeImage. This script has optional switches to specify the stone name and to set to size of the GEM_TEMPOBJ_CACHE_SIZE used for the upgrade process.

upgradeImage [-h] [-c cacheSize] [-s stoneName]

-h prints this usage information.

-c cacheSize sets the size of the GEM_TEMPOBJ_CACHE_SIZE; if this is not used, the script will default to use a value of 100000.

-s stoneName sets the name of the running stone to upgrade; if this option is not used, the script will default to gs64stone.

For example,

 upgradeImage -s stoneName36

The script will prompt you to press the return key to begin.

The script invokes subordinate scripts to complete the upgrade. The upgrade process will take some time. You can examine the progress, if desired, by examining the file $upgradeLogDir/upgradeImage*.out.

The script should complete with the message:

Upgrade completed. No errors detected.

If not, please preserve the Stone log file and the contents of $upgradeLogDir. Contact your internal GemStone support person or GemStone Technical Support.

3. Restore System Account passwords

Log in to GemStone/S 64 Bit version 3.6 as DataCurator or SystemUser, and change the password for SystemUser, DataCurator, and GcUser to a secure password, such as the passwords used for these accounts in v3.5.4. For example:

topaz 1> run
(AllUsers userWithId: 'SystemUser') password: '354Password'.
(AllUsers userWithId: 'GcUser') password: '354Password'.
(AllUsers userWithId: 'DataCurator') password: '354Password'.
System commitTransaction

where 354Password is the account password used in version 3.5.4.

GsDevKit Upgrade

If you are using the open-source Development Kit for GemStone/S 64 Bit (GsDevKit, also referred to as Seaside or GLASS), you will need to perform another step to upgrade your GsDevKit image. This step upgrades the GsDevKit base code, and you will also need to reload your application code.

For details, see Upgrading GLASS/GsDevKit Applications.

When you have completed the GsDevKit upgrade, continue with the upgrade process and perform the following steps.

Post-upgrade Application Code Modifications

1. Reinstall any other GemStone products that modify kernel classes.

If you use GemConnect or GemBuilder for Java, you must reinstall the appropriate version of these products into your repository at this time.

To install, use the procedure in the Installation Guide for that product.

2. File in Kernel class changes

If you have modified any kernel class methods of the previous version or if you have added methods to kernel classes, carefully compare your changes with the changes in version 3.6 to see whether your changes are still necessary or appropriate. Carefully review the Release Notes for each intervening version, as well as examining code in the image.

If the kernel class changes are still applicable, file in the changes, verify that errorcount is 0, and commit.

Make Backup

1. Make backup

At this point, you should create a full backup of the upgraded repository.

Configure GCI clients and GBS

1. Recompile User Actions

It is recommended to recompile and relink User Action libraries.

2. Configure GBS

If you are using GBS clients, ensure you are running a supported version of GBS and client Smalltalk. You must use GBS version 8.5 or later for VW, or GBS 5.4.6 or later for VA, to connect to a GemStone/S 64 Bit v3.6 repository.

Configure GBS to use the version 3.6 client libraries. Depending on the GBS version you are upgrading from, the required libraries, library naming conventions, and the process GBS uses to identify the correct library to load may have changed.

See Configuring GBS for GemStone/S 64 Bit for details. If your GBS clients run on a different platform than your GemStone server, refer to the Installation Guide for that platform.
