Multi Instance (multi lane) flows not Completing

Hello team

I have the followig issue:

Flows with parallel execution (multi-lanes) does not progress. (each individual lane complete, but the flow never progresses from there).

Tried modifying the worker threads/heap size, etc... But is working on another environments with same configuration. I saw a same issue rised here years ago but with no final known resolution.

Any clue?

OO is 10.80 upgraded from 10.60

Thank you,

Francisco

Hello, thanks for replying.

Checked status of OO_triggers (see attached) and no, nothing was showing blocked. Sorry where should I look for "next_fire times" ?

Thank you again,

Francisco.

Hi Francisco,

 

Fire time can be check either from the OO_TRIGGERS table (you will see two colums, prev_fire_time and next_fire_time in epoch time) or from the monitoring page, in the jobs section you will see the previous execution and next execution time.

Thanks;

Re: Multi Instance (multi lane) flows not Completing

I was able to find one job "splitJoinJob" which "Next execution" was in the past.

I changed to some minutes in the future, nothing happened, time passes and now is in the past again.

I see another one, "jobDetail" that show good on previous (yesterday) and next (later today) but shows the following characters in column "Period or cron expression"

0 05 22 ? * *

Not like the others . . .

 

Should I replace that expression with something different?

Re: Multi Instance (multi lane) flows not Completing

I put the job in a time in the future and as the time passes, it is left "in the past" again.

On all other jobs the times are updated, this one keeps the one I manually input in the db table.

Do I need to stop/start force something?

 

Thank you,

Francisco

Hello

From the descirption of the problem and the splitJoinTrigger NEXT_FIRE_TIME not updating, it seems like you have an extra recovery job created , by quartz library that is blocking this job to trigger. 

In case you have any entries in OO_TRIGGERS table starting with "recover", please delete those rows ( it can be 1 entry per each central , in case each central had to be recovered at some point in time) .

Also in OO_FIRED_TRIGGERS, if you have an entry for splitJoinTrigger, delete that one also. 

Restart Central(s) after this deletion. 

Monitor the PREV_FIRE_TIME and NEXT_FIRE_TIME of all jobs are updating correctly.
