Sun Java System Application Server Enterprise Edition 8.1 2005Q2 Update 2 Release Notes

- Previous: Bugs Fixed in the Enterprise Edition 8.1 Update 2 Release
- Next: HADB File System Support

## HADB Enhancements

- A new management command `hadbm setadminpassword` has been implemented to allow changing the password used for database administration. The command takes options indicating which management agent to use, and the old and new password. For more information, see the `hadbm setadminpassword` man page.

- The existing management command `hadbm listpackages` has been modified. Previously, the command took no operands, and listed all packages in the relevant management domain. The modifications introduces an optional package name operand, and lists only packages with that name. If the operand is not provided, all packages are listed. For more information, see the `hadbm listpackages` manpage.

- The existing management command `hadbm createdomain` has been modified. The hostlist operand is extended to also specify the port number of the management agent. In this way, the domain is completely specified using only the hostlist operand. The old behavior is still supported for backward compatibility. For more information, see the `hadbm createdomain` manpage.

- Some of the error messages from the management system have been modified. The modifications are intended to improve understandability, consistency and accuracy of the error messages. The actual modifications are not listed in these release notes.

- The installation and uninstallation behavior has been slightly changed. Installing or uninstalling the HADB should always preserve the softlink `/opt/SUNWhadb/4`, but this has not always been the case.

- The possibility of entering passwords on the command line as a command option is deprecated. This is relevant to all `hadbm` commands taking passwords as command line options. For `hadbm` commands, it has previously been possible to enter a password as:

  1. A password file

  2. A command line option

  3. An interactive input

  Method 2, the command line option, is considered unsafe, and is therefore deprecated. A warning message is issued if a password is entered in this way. Instead, use a method 1, password file, or method 3, interactive output. Using a password at the command line will become obsolete in the next release. Note this applies to all `hadbm` commands taking a command line password option.

- HADB has been upgraded to use JGroups Version 2.2, and its source code is distributed along with the HADB. To support online upgrade from a previous HADB version, both JGroups 2.1 and 2.2 are delivered with HADB. For JGroups 2.1, byte code is delivered only.
