Slow JTX performance remedies?

AndrewRudin — Fri, 16 May 2014 22:00:51 GMT

My JTX users have reported our system becoming slower, particularly when running workflows. It seems to have gotten slower over time and now we are up to 11,000 jobs after 7 years. Below is a list of our JTX system tables and a record count for each.

I'm curious if there are common things to look for with bigger JTX repositories. My users have mainly mentioned slow response when running through our workflow. I have some steps that execute sql and it seems to take a while and my guess is its making a new connection to the database just to populate one field in a table. Otherwise it seems some of the other steps take some time as well. We first thought exporting and removing some of the older jobs and job_types would help, but then we found out we can only really export abut 1000 of them, since the other 10,000 are used when we query the system. However, by removing those 1000 we could delete a lot of old step types and job types. I would think its the bloat in the JTX_HISTORY, JTX_JOB_STE_XREF, and JTX_JOB_STEP and JTX_STEP_STATUS and JT_STATUS_HIST that could be causing slow response when moving about the workflow.

Thank you for any help you can provide,
Andrew

Hi Andrew,

One thing that caught my eye is your comment about having some steps that run SQL. It may be worth reviewing these steps to ensure that the fields that they're using for queries have attribute indexes.

I checked one of the Workflow Manager databases that I use, and (for example) in its JTX_HISTORY table, there was an attribute index on "OBJECTID" and another on "JOB_ID", but not on any of the other fields. You'll probably have comparable indexes set up on each table just from the Workflow Manager post-install. But if you've developed your own queries against the database using fields that aren't indexed, or set up your own tables, or certainly if one of these indexes is missing for any reason, that could lead to a performance hit over time as the number of records in these tables gets larger.

Another way to investigate/confirm what's happening would be to run through these steps with Workflow Manager logging enabled. This might provide some more insight as to where the application is spending its time.

Hopefully that helps,

Brian D.
