Known issues

See the individual product release notes for related known issues:

• exteNd Director Release Notes
• exteNd Composer Release Notes
• exteNd Application Server Release Notes

Installation

• The InstallAnywhere wizard uses a temp directory for storage at the time of install. Depending on what you choose to install, the temp directory will grow to three times the size of the actual files. For the entire suite, this could approach the 2 GB range.
• The size of the actual files on disk may be from 0 to 100 MB larger than what is estimated by InstallAnywhere during the install. The entire suite should not exceed 820 MB.

MySQL known issues

MySQL 4.1 is not supported in production environments at this time. MySQL 4.1 ships with exteNd 5 on Windows, Linux, and Solaris at this time. This software is alpha quality at the time of exteNd 5 ship and is not supported in any production environment. Novell recommends using another commercially available database from the exteNd list of supported database vendors for any production application. Note that MySQL 4.1 for NetWare was not available at the time of the exteNd 5 ship. When MySQL 4.1 becomes stable on all platforms, work will be done to certify exteNd 5 against the database and add it to the exteNd list of supported databases for production.

• MySQL 4.1, which ships with exteNd 5, is NOT supported in production environments.
• (Windows only) Avoid using the MySQL that ships with exteNd 5 if you do not want to conflict with an existing MySQL installation. If you have a different database from the exteNd list of supported database vendors, you can choose to use that database while running through the Custom option of the exteNd 5 install.

 

• Multibyte character support (MBCS) currently does not work. The MySQL development team missed compiling utf8 support into MySQL alpha 4.1.0. It should be fixed in 4.1.1. This information is posted at: http://groups.google.com/groups?q=mysql+utf8&start=10&hl=en&lr=&ie=UTF-8&oe=UTF-8&selm=bbqcqt%24qeg%241%40FreeBSD.csie.NCTU.edu.tw&rnum=17
• No subquery optimization in the 4.1.0 alpha release of MySQL. The MySQL development team has fixed this in the next alpha release. This has little impact on normal DAC and PMC processing, but the following situations can cause MySQL to use up to 99% of the CPU for a considerable amount of time:
  • Copying folders in the Content Management subsystem
  • Importing a zip file into the Content Management subsystem




• SQL NOT statements are not evaluated as expected in some cases. Extend Director does not have any code that is affected by this, but developers may run into it when writing their own SQL code. For example, say you have a table1 with the following columns and rows: key_column value_column 0 value0 1 value1 2 value2. The following SQL statement returns an empty result set: SELECT key_column FROM table1 WHERE NOT value_column = 'value0'. If you put parentheses around the evaluation condition, it returns keys 1 and 2 as expected. SELECT key_column FROM table1 WHERE NOT (value_column = 'value0'). The MySQL team is consulting the SQL-99 standard team to determine whether this is a bug.
