Check persistence of exception field in JobImpl ----------------------------------------------- Key: JBPM-1685 URL: https://jira.jboss.org/jira/browse/JBPM-1685 Project: JBoss jBPM Issue Type: Task Security Level: Public (Everyone can see) Components: PVM Reporter: Guillaume Porcher Priority: Critical in jobs, there is a exception field to put the exception stacktrace in hibernate mappings, this column length is set to 4000. Some stacktrace are more than 4000 char long, this creates an exception with hibernate. <tomb> porcherg: the 4000 is because of some DB limitation <tomb> i believe db2 <tomb> iirc, in db, the max string field is 4000 <tomb> if you want to go beyond that, we would need to use CLOBs <tomb> but i'm open to alternatives <tomb> maybe the stacktrace field should be a CLOB ? <porcherg> tomb: the problem is that it creates an exception if it is too long <tomb> yes <tomb> so we have to fix it somehow <tomb> just removing the 4000 limit is not good <tomb> as it will not work on db2 <tomb> so we either manually truncate the exception field in the code <tomb> in the setter <tomb> or we change it into a clob <tomb> probably the latter is better <porcherg> maybe we can use hibernate "text" type <porcherg> "text: Maps long Java strings to a SQL CLOB or TEXT type. " <tomb> do you guys have access to db2 db ? <tomb> the first thing we should do is verify if this problem is really present <tomb> so we should remove the 4000 limit in the hibernate mappings and see if we can create that problem on db2 <tomb> once we can reproduce it, then we can start looking for alternatives that fix the problem on db2 <tomb> then we can see if the fix works on the other dbs <tomb> i am a bit reluctant to start using clobs <tomb> as this would be the first use case for it <tomb> and clobs might lead to even more DB dependent issues... <tomb> but if there is no other way, then we have to <tomb> so let's start by removing the 4000 limit in the hibernate mappings and prioritizing that we have to test it in db2 -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
