We are seeing servers dropping out of the “Active Servers” table in the Admin Console > Agent Manager page. We are running multiple environments, each with platform version 184.108.40.206 with two UI and two process servers, and have experienced this across multiple environments. Current observations:
- Both UI and process servers can drop out, and it’s not the same server every time.
- Servers can be accessed and logged into, even if they are gone from the “Active Servers” table.
- A restart of the server will make the servers appear again.
Our current approach is to monitor daily and when a server drops, take a look in the logs for that day. Any other ideas? What controls when servers are listed or not in the “Active Servers” table in the Admin Console > Agent Manager page?

We have quite a lot of rows in the extended formula queue that started to back up since Aug 29. At one point, we had over 900K in the queue and the process server is processing it pretty slowly. As of Sep 8, the system is still processing the queue. We are adding daily on average over 125K rows to the EF_QUEUE table.
We tried starting and stopping the Extended Formula Agent and Formula Recalc Agent and tried rebooting the process servers. We swapped the agents to run on different servers. We also ran the segment shrink on the EF_QUEUE table and gathered statistics. It is still extremely slow. We still have over 500K in the queue.
In parallel, we did open the platform logging on the extended formula activity and cache building, and we are working to identify the processes that can be fixed to reduce the multiple calls to the Extended Formula Agent queue. Do you have any recommendations to speed up the process to clear the extended formula queue?
Review the following two APARs. They may need to be applied to your environment to address this issue: (1) Platform: APAR IV87030. (2) Application: APAR IV87104.

In one of our environments, we have a large amount of records that have been transitioned to the null state. When the Cleanup Agent runs, it runs out of DB2 transaction log space executing the following:
DELETE FROM IBS_SPEC_ASSIGNMENTS WHERE EXISTS (SELECT ‘X’ FROM IBS_SPEC_CA_DELETE WHERE IBS_SPEC_CA_DELETE.SPEC_ID=IBS_SPEC_ASSIGNMENTS.SPEC_ID)
For workflow instance saves, the Cleanup Agent now seems to remove the data in small chunks (of 1000 rows each). But for the record data cleanup, it still seems to (try to) remove all data in one huge SQL statement/transaction. Is it possible to get the Cleanup Agent to remove record data in chunks, like it does for workflow instance saves?
Otherwise, I’m thinking of writing a small util that would run the statement above, but in smaller chunks, since it seems we still have the list of record IDs that it tries to remove in the IBS_SPEC_CA_DELETE table. Any obvious issues with that?
As of 3.5.3, there have been no changes for the data to be deleted in chunks for IBS_SPEC_ASSIGNMENTS. This sounds like a good PMR. It is rarely recommended to delete records directly from the database, but in this circumstance, you might be okay. However, the IBS_SPEC_CA_DELETE only exists during the time the Cleanup Agent is running. It is dropped when the agent goes back to sleep.

You can configure TRIRIGA to use Tivoli Directory Integrator as its ETL runtime engine to run ETLJobItems from within TRIRIGA.
Before you begin
Install Tivoli Directory Integrator, if not already installed, on all the TRIRIGA systems that could run a TDI ETL Job Item. During the TDI install:
- Make note of the installation directory you enter on the Destination panel. You will enter this value later in TRIRIGAWEB.properties.
- Select either installation type. TRIRIGA requires only the TDI Server component.
- When prompted for the location of the Solution Directory, you can select any option. TRIRIGA specifies its own solution directory at runtime. However selecting the option “Use Install Directory” may simplify troubleshooting.
- Make note of the value you enter in the Server Port field on the Server Port Values Panel. You will enter this value later in TRIRIGAWEB.properties.
- Clear the “Start the Configuration Editor” check box on the Install Complete panel.
- Note: This step is very important for TDI/TRIRIGA integration to work. After you have installed Tivoli Directory Integrator, update it with the recommended fix packs (per TRIRIGA support matrix). TDI must be at least at FP04 (220.127.116.11) or it will not automatically start the TririgiaETLDispatch.xml assembly line which will result in ETL job items failing to run successfully.
- Edit TRIRIGAWEB.properties file to enable TRIRIGA to manage TDI server. Set the following properties…
- Install a JDBC driver library so that Tivoli Directory Integrator can use it to access TRIRIGA database…
- Edit TDI global.properties file to allow TRIRIGA to check and stop the TDI server from localhost without requiring authentication and authorization certificates. Set the api.remote.ssl.on property to false to tell TDI to trust requests from localhost…
- Start Tivoli Directory Integrator Agent from TRIRIGA Admin Console and verify that it starts successfully…

In the Admin Console, Performance Monitor, when monitoring a single value, it returns bad results. Returns wrong agent’s status. Returns “false” for an agent status even if the agent is running. Returns “0” for the number of agents running even if multiple agents are running.
We needed to update the calls to various platform status APIs. Moving forward, we updated the Admin Console, Performance Monitor, Single Value to correctly obtain the status of the active agents. This means the AGENTS_RUNNING_COUNT, OBJECT_PUBLISH_AGENT_RUNNING, SCHEDULER_AGENT_RUNNING, and all other agent-related monitors will now correctly report the agent status and count. We also removed the calls to KEYWORD_PARSER_AGENT_RUNNING and WAREHOUSE_AGENT_RUNNING as these no longer exist.

When emails are sent to TRIRIGA using Apple’s Mail client, they are not always being interpreted properly on the TRIRIGA end. Some problems include:
- When a rich-text email is sent using Apple’s Mail client and has an attachment, the attachment isn’t seen if the email history is present as part of the email. If the email history is removed, the attachment is seen.
- When a plain text email is sent using Apple’s Mail client and a PNG or JPG attachment is present, the attachment isn’t seen, but the email body has a marker that makes it look like an embedded image should be present (but isn’t).
- When a plain text email is sent using Apple’s Mail client and text exists in the email before the attachment, the text that exists in the email before the attachment isn’t seen. Any text that exists after the attachment is seen.
Apple mail formats the attachments and forwards differently than other mail clients. Moving forward, an issue that cause attachments to be missing and email bodies to lose content when the mail client puts attachments inline, has been resolved.
