SQDR Plus for iSeries Release Notes

StarQuest Data Replicator Plus for iSeries v3.75 Release Notes

Februrary 2012

Introduction

StarQuest Data Replicator (SQDR) is a replication software product that allows you to copy data between IBM DB2, Oracle, MySQL, Informix, and Microsoft SQL Server database environments.

The base StarQuest Data Replicator software runs on Windows and provides full refresh replication, which copies all the source data that you specify for replication, regardless of when that data was last replicated. This provides a “snapshot” of the specified source data at the time of replication.

SQDR Plus for iSeries is a separately licensed component that provides incremental replication support for SQDR users. Incremental replications copy only the data that has changed, reducing the amount of data that is transferred and allowing the replication to occur more frequently.

The following topics are addressed in these Release Notes. Refer to the appropriate SQDR Plus Quick Start Guide at http://www.starquest.com/Supportdocs/browseQuickStarts.shtml for detailed information about installing StarQuest Data Replicator Plus for iSeries for the first time. The SQDR Plus Quick Start Guides include instructions for installing both SQDR and SQDR Plus. Refer to the SQDR Plus for iSeries Users Guide for detailed information about using the StarQuest Data Replicator Plus for iSeries software.

The base StarQuest Data Replicator software (for Windows) contains its own readme file and online documentation; refer to those documents for information about the SQDR base software.

What's New in this Release

This release of the StarQuest Data Replicator Plus for iSeries introduces the following new features and improvements.

  • Configurable inactivity timer: The default behavior of SQDR Plus is to check for inactive clients every twenty four hours (1440 minutes). You can change this interval by setting the clientMonitoringInterval in sqagent.properties; the value is specified in minutes.
  • Support for XML and DECFLOAT datatypes
  • Configurable congestion thresholds: Two new configuration properties, specified in minutes, can be configured in sqagent.properties: congestedThreshold (default 5 minutes) and uncongestedThreshold (default 1 minute). A journal reader inside the capture agent is considered "congested" when the lag-time between when the log records were created and when they are processed by the reader exceeds the value configured for "congestedThreshold". The journal is considered uncongested when this lag-time reaches the value configured for "uncongestedThreshold". Both events are logged as INFO, and may result in email notifications. When the capture agent is started, the congestedThreshold configuration setting is used as a grace period during which a congested condition is not reported; the grace period does not affect the collection of lag-time statistics.

Upgrade Considerations

This section describes issues of interest for users who are upgrading from a prior version of StarQuest Data Replicator Plus for iSeries.

  • If you are upgrading from a prior release of SQDR Plus for iSeries, be sure to review Updating the SQDR Plus Software on page 23 of the SQDR Plus for iSeries Users Guide before you install the new version of the software.
  • You must connect to the AS/400 with the same user ID that you used during the original installation. If you attempt to run the upgrade with a different userID, the installer will display a dialog showing the correct user ID and ask you to restart the installation.

FixPak and PTF Notes

Refer to the SQDR Plus Quick Start Guides at http://www.starquest.com/Supportdocs/browseQuickStarts.shtml for specific IBM issues and the FixPak and PTFs that may be necessary for StarQuest Data Replicator Plus for iSeries to function properly.

CCSID values:

Both the installing user and the Capture Agent user must be configured for a CCSID (Coded character set identifier) other than the AS/400 default of 65535 (*HEX).

The default behavior of the installer is to create the Capture Agent user with a CCSID of the system catalog (typically 37on US English systems). During installation, this value can be changed to any valid CCSID or to *SYSVAL (use the system value QCCSID).

During installation, the CCSID of the installation job is changed to the same value as the Capture Agent user. If you wish to use a different CCSID during installation, this value can be changed to any valid CCSID or to *SYSVAL.

To examine what CCSID value is normally used by the installing user, use WRKUSRPRF <user> and scroll to the last page. If "Coded character set identifier" is set to *SYSVAL, then check the system value with DSPSYSVAL QCCSID.

Java versions:

If you have multiple Java versions installed, make sure that the correct version is being used - Java version 1.4 or later is required for correct operation. The default JDK version is typically the latest version present.

To verify the version of Java being used, log in as the installing user and type "java -version" at a QSH or PASE command prompt or "QSH CMD('java -version')" at a CL prompt.

On v5r3 and v5r4, If the result shows that your active JDK version is earlier than 1.4, you should specify the Java version (for the Classic JVM) by setting java.version=1.4 in

/QIBM/UserData/Java400/SystemDefault.properties (system-wide)

or

/home/<user>/SystemDefault.properties (user-specific).

If the command results in the error "qsh: 001-0019 Error found searching for command java. No such path or directory." then there may be a problem with the PATH or with the symbolic link /usr/bin/java. If you get this error, refer to the IBM technote 86256E3D008188C0 QSHELL 001-0019 No Such Path or Directory.

System Values:

To ensure a complete installation of the SQDR Plus product, be sure that the system value QALWOBJRST is set to *ALL. If the value on your system is something else, set it temporarily to *ALL while running the installation and then restore the original value.

Installing and Using the StarQuest Data Replicator Plus for iSeries Software

Known Issues

  • When installing from a Windows system, the installer files should be copied or extracted to a temporary directory on the system drive (e.g. C:\). If you run the installation from a drive other than the system drive, you may see the following error message at the end of the installation. This error is harmless and can be ignored:

[java.io.FileNotFoundException:
\DOCUME~1\user\LOCALS~1\Temp\2\ismp001\1923345.tmp
(The system cannot find the path specified)]

  • SQDR Plus for iSeries does not support the incremental replication of partitioned tables.
  • Use JRE 1.4, 1.5, or 1.6 on the installing system; running the installation with JRE 1.7 results in the error message "The wizard cannot continue because of the following error: could not load wizard specified in /wizard.inf"
