Activiti 6 Deadlock on delete and select ACT_RU_JOB on MSSQL Server

Jump to solution

Hi 

we recently upgraded from activiti 5.2.x to activiti 6 and now we have deadlock issue on out database.

The sql statement which is the source of deadlock is as follows:

(@P0 nvarchar(4000),@P1 int)delete from ACT_RU_TIMER_JOB where ID_ = @P0 and REV_ = @P1       

We have tried to add non-clustured index on ID_  AND REV_ however the lock still exists.

the above is the source of issue which cause lock on the followings:

(@P0 nvarchar(4000))select * from ACT_RU_JOB where ID_ = @P0   

(@P0 datetime2,@P1 int,@P2 int)SELECT SUB.* FROM (
select
RES.* , row_number() over (ORDER BY RES.ID_ asc) rnk FROM ( select distinct RES.*
from ACT_RU_JOB RES
where RES.LOCK_EXP_TIME_ is not null and RES.LOCK_EXP_TIME_ < @P0
)RES ) SUB WHERE SUB.rnk >= @P1 AND SUB.rnk < @P2

(@P0 int,@P1 int)SELECT SUB.* FROM (
select
RES.* , row_number() over (ORDER BY RES.ID_ asc) rnk FROM ( select distinct RES.*
from ACT_RU_JOB RES
where LOCK_EXP_TIME_ is null
)RES ) SUB WHERE SUB.rnk >= @P0 AND SUB.rnk < @P1

Please let me know what further information you require and will provide you 

regards

Nikan
