ISL AlwaysOn
ISL AlwaysOn - Module - Performance optimization in ISL AlwaysOn connect procedure (FEATURE) [ISLALWAYSON-859] More
DescriptionA number of steps have been taken to optimize the performance of the ISL AlwaysOn module for ICP, such as:
- Reworked load balancing
- Changed computer status gets handled less often
- Removal of unnecessary memory copies
- Tweaking of the parameters that control database flushing
ISL AlwaysOn - Module - implement grid query in conf computer list (FEATURE) [ISLALWAYSON-860] More
DescriptionIt was previously only possible to view connected AlwaysOn computers on the observed server (Activity Monitor -> Sessions -> Active). This has been extended to show connected AlwaysOn computers on the whole GRID.
- Users first need to search for computers. The default search string displays example usage. It is possible to use regular expressions.
- After the search has been executed and computers have been found, the computers are displayed under "GRID Computers".
ISL AlwaysOn - Module - show number of all ISL AlwaysOn computers in stats (FEATURE) [SLALWAYSON-863] More
DescriptionICP now shows the number of AON computers connected. This can be found in Activity Monitor -> Sessions -> Active -> ISL Always On, under Grid Stats -> Computers.

DescriptionISL AlwaysOn sends a custom field to server, where it is stored to the database. The custom field values can be observed at Activity Monitor -> Sessions -> Active -> ISL AlwaysOn. By default, this field isn't indexed. To index this field, set "islalwayson_custom_field_index=1" in the dboptions file.
ISL AlwaysOn - Module - aon connects using webapi are not stored in session history (DEFECT) [SLALWAYSON-612] More
DescriptionWhen using ISL AlwaysOn Connect through the webapi (e.g. with ISL Light 4), the connection was not stored in session history. This could be observed by a lack of entries in Computer History of the ISL AlwaysOn ICP module.
This defect was fixed.
ISL AlwaysOn - Module - v3 share computers page does not work if a computer description is empty (DEFECT) [SLALWAYSON-832] More
DescriptionWhen editing an AlwaysOn computer using the version 2 of the ISL AlwaysOn web interface (Configuration -> ISL AlwaysOn -> Which version of ISL AlwaysOn web interface to show), it is possible to leave the computer description empty. If the web interface version was then changed to version 3, the empty description caused some errors:
- The computer description in the list of "My Computers" would be empty.
- When editing the computer, the description would be shown as undefined.
- When using the Bulk Share action, the message "Loading list of computers..." would also contain an "undefined:" string.
To fix these errors, version 2 of the web interface still allows the description to be left empty, but it now just uses the computer name as its description instead of setting it to empty.
This defect was fixed.
ISL AlwaysOn - Module - Add timerange ( today ) to UI version 3 (single computer aon history and bulk computers history ) (DEFECT) [SLALWAYSON-843] More
DescriptionUsers can view the connection history for a specific computer by selecting "More ..." -> "Computer History". From there, users can select the Time Frame from a drop-down menu.

This defect was fixed.
ISL AlwaysOn - Module - Remove database table "aon locations" as it is not used anymore (DEFECT) [SLALWAYSON-861] More
DescriptionISL AlwaysOn used to store a database of statuses of connected computers, which impacted performance. ISL AlwaysOn will now directly notify servers about its status, dropping the need for a database table.
This defect was fixed.
ISL AlwaysOn - Module - Web interface v3 has javascript error when editing computer and language is set to French (DEFECT) [SLALWAYSON-877] More
DescriptionIf a user wanted to edit an AlwaysOn computer through the web interface, while having the language set to French, the edit window would not show. This was due to an error in generating the HTML for the edit window from a template, where at most one apostrophe in the template was considered. Because of this, the problem wasn't limited to the French language.
This defect was fixed.
ISL Light
ISL Light - Module - grid call to session_type with session code should return session id (FEATURE) [ISLLIGHT-2786] More
DescriptionA GRID call to light_session::session_info, provided with a session code, also returns the session id.

DescriptionIn case users transferred session to another user who already had sessions active ( using multisession option ) the newly transferred session was using another license even though it should not. Checker for multisession was redesigned, in case the same machine is used it should use the same multisession id thus using only one license.
The defect was fixed.
ISL Light - module - prevent multiple valid active codes (DEFECT) [ISLLIGHT-2888] More
DescriptionOn the rare occasion that two identical active session codes were generated, it was possible for the client to connect to the wrong session. The fix ensures that the client is refused connection if using a valid session code from another session, even if that session has already ended. A valid session code remains active for at least one hour.
This defect was fixed.
ISL Light - Module - resolving code from ISL Light Client 3.2 and older does not use activeCode memory map (DEFECT) [ISLLIGHT-2894] More
DescriptionWhen resolving the session code from a ISL Light Client version 3.2 or older, only the database was searched to check for active codes. However, active codes are also separately stored in active memory. Not searching the active memory could result in connecting to an invalid session.
This defect was fixed.
ISL Light - Module - session codes should begin with non-zero number (DEFECT) [ISLLIGHT-2908] More
DescriptionGenerating a session code that began with a zero caused problems with integrations, leading to longer connect times. Session codes do not start with a zero anymore.
This defect was fixed.
ISL Light - Module - templating error in common.js (DEFECT) [ISLLIGHT-2951] More
DescriptionThe function for generating HTML code from templates did not consider more than one apostrophe character in the template, leading to errors.
