uc.png Tips, tricks and common problems with solutions for migration from RRC4.x to RRC5.0

Authors: MinIdzelis, RichForziati, GailBurati
Build basis: Rational Requirements Composer 4.x to 5.0

In RM 5.0, the data is no longer stored on the JTS server. Rather, it is stored with the RM server itself. The movement of the data from JTS to RM has caused significant changes and several additional steps for the 4.x to 5.0 upgrade procedure.

The database administrator must first create a copy of the JTS database to be the new RM database. After that, use the interactive upgrade guide to create a customized set of instructions to follow during upgrade. Most of the time, this will use the rm_upgrade.[sh|bat] wrapper script to guide CLM administrators through the upgrade. However, in some cases (distributed without a shared drive or windows with DBCS code page) the script will create a sequence of RepoTools commands that doesn’t use the wrapper script.

The RM upgrade script (rm_upgrade.[sh|bat]) includes the following steps:

  1. updateConfigurationFiles*
  2. addTables**
  3. finalizeApplicationMigration (RM)
  4. finalizeApplicationMigration (JTS)
  5. reindex
  6. updateProjectBacklinks** (When RM offline) or updateProjectBacklinksOnline** (When RM online)

* Requires user interaction to specify new JDBC database connection, rest of prompts are confirmations

** Requires user interaction for confirmation prompts only

Recommendations

  • Use the Interactive Upgrade Guide to generate the upgrade instructions for your deployment
  • Use a staging area with copies of your data to run through the upgrade and create time estimates for your particular upgrade
  • Backup your CLM databases prior to the upgrade - the copy of the JTS database to the new RM database can be done during this same downtime
  • Have the following pieces of information handy before starting the upgrade:
    • the install directory or directories of your CLM 4.X applications
    • the install directory of your new JTS 5.0 (possibly via mount if remote)
    • JDBC connection syntax for the new RM database
    • JDBC connection password for the new RM database
    • RM public URL of your deployment
  • Upgrade JTS, then RM, then the other CLM applications

Common problems

Editor (to verify properties) doesn't work on Linux

During the updateConfigurationFiles step the JTS and RM teamserver.properties files are opened in an editor for users to inspect or update. This does not work on Linux. See defect 87659 Workaround: open files manually.

Reindex step

The reindex step is not required and, if skipped, the indices will be built once the RM server is brought online, we recommend running the reindex to complete the upgrade and improve performance once the server is brought online.

If running the rm_upgrade.[bat|sh] script, there is no progress indicator displayed in the command window during the reindex (See defect 87722). There are progress updates written to the rm_upgrade_rmupgrade.log file in the server directory.

If running the reindex step manually, the progress indicator will appear in the command window.

Resuming where you left off from a failed step

If the upgrade script fails during any of the steps you are not able to resume from the point of failure. You can re-run the upgrade script from the beginning and skip the steps that succeeded. (See defect defect 87732).

Upgrading multiple apps at the same time

While it is possible to upgrade all the applications in a distributed CLM environment at the same time it is not recommended. The first portion of the RM upgrade requires other applications to be offline. Then for the updateProjectBacklinks step the applications need to be brought online. Exactly when each of the applications should be upgraded during this process can be confusing and it is not fully documented in the IUG yet. (See defect 314856 ).

The other applications do not have to be at 5.0 yet in order to complete the updateProjectBacklinks step.

It is best to fully complete the JTS upgrade then complete the RM upgrade separately from the CCM and QM upgrades. You can still perform the upgrades in any order after the JTS upgrade. It's just less confusing to perform the upgrades separately.

Script execution directory

When using the rm_upgrade.[sh|bat] script, be sure to run it from the /server directory, specifying the path to the script

C:\Program Files\IBM\JazzTeamServer\server>upgrade\rm\rm_upgrade.bat

Ordering of upgrades

Be sure to run JTS upgrade BEFORE running RM upgrade. If you run RM Upgrade first, you may run into the following problem:

This is because the file you used was a brand new JTS file, and it didn’t have the required properties. To fix this, upgrade JTS first, then rerun the upgrade script.

Similarly named commands

There are two steps that execute similarly named repotools commands.

repotools-rm.bat -finalizeApplicationMigration

repotools-jts.bat -finalizeApplicationMigration checkOauthDomain=true applicationId=RM-application-id newPublicUrl=NEW_RM_PUBLIC_URL

Verify arguments for RM finalizeApplicationMigration command

Do not specify arguments checkOauthDomain=true or applicationId=RM-application-id or newPublicUrl=NEW_RM_PUBLIC_URL when executing the RM finalizeApplicationMigration repotools command. Undetermined behavior will result.

Verify arguments for typos

Check the newPublicUrl argument for typos. If you notice that ‘unresolved context’ appears when viewing RM projects in the /admin page, check the parameters to this command. They are not verified and will be used as is.

Verify arguments for JTS finalizeApplicationMigration command

If you do not specify checkOauthDomain or set checkOauthDomain=false, then you MAY have problems creating new projects from the /admin page.

Use the appropriate Oracle DB version

You will get an error during addTables if you do not use the appriopriate Oracle DB2 version driver and database.
