Patch Bundle PE71-B070730 available for Eloquence B.07.10

To make downloading and installing the current set of recommended Eloquence patches more convenient, we have created the patch bundle PE71-B070730, which combines the 14 current patches into a single installation archive.

While the patch bundle is much more convenient than having to deal with up to 14 separate patches one by one, you need to keep in mind that the patch bundle installation does not perform special checks on the file versions that it replaces.

So, if you plan to install a patch bundle together with more recent superseding patches (no matter whether recommended or beta), make sure to first install the patch bundle and then the more recent patches.

Eloquence B.07.10 recommended patches updated

We have recently added a number of patches to the Eloquence B.07.10 web page that lists recommended patches. They cover components like the database server and utilities as well as the language core and related libraries.

The patches provide bug fixes and/or enhancements to the respective product components. As some of the bug fixes are considered "critical", we recommend that you review the patches and apply them depending on your individual strategy for proactive patching. For new installations or updates, for example, it is always a good idea to also install the latest patches.

Note that some of the patches have dependencies, which are mentioned on the web page and in the individual patch descriptions. For example, when installing the eloqdb6 database server patch, you should also install the matching versions of dblogreset, dbrecover, and fwaudit utilities.

Eloquence replication available as B.07.10 patches

We have recently released a set of patches for Eloquence B.07.10 that add the database replication functionality which will also be part of the upcoming Eloquence B.08.00 release in the future. The patches have passed our internal testing successfully and have also been installed by several customers since then. For now we are keeping the patches marked "beta" as we have not yet received sufficient customer feedback to make them recommended patches. Additional feedback is welcome.

The new replication feature allows to replicate database transactions from a "master" server to one or more "slave" servers, typically close to real-time (depending on server performance and network bandwidth). The slave servers are available to users in read-only mode and can be used for load balancing or emergency fail-over scenarios, for example.

Note that the replication functionality is an optional feature of the database server and needs a separate "repl" license key on the "slave". Temporary license keys for evaluating this new feature are available.

Eloquence B.07.10 patch PE71-0704110 enhances database server statistics

This patch adds the option to log summary performance metrics of individual database sessions.

The enhancement provides a second file for database server statistics, the so called "SessionStatFile", in addition to the current "StatFile", as well as options to control when and how output is written to those two files.

The StatFile focuses on providing metrics for the server as a whole; for example, overall database server utilization, number of connected clients, disk read/write rates. The SessionStatFile focuses on metrics for individual client sessions; for example, when and how long a client was connected, how many IMAGE calls (dbget, dbupdate, dbput, etc) it performed during its lifetime and how much total time it spent there.

Some of these metrics are also available through the "http status monitor" (if the ServiceHttp option is configured in eloqdb6.cfg), but the web page only shows the server metrics for the last 10 minutes and the client thread metrics as long as the client is still connected. The StatFile and SessionStatFile capture the data for later analysis.

The two files are controlled by config file settings and/or dbctl.
