>From the Liquibase v2 Upgrade help <http://www.liquibase.org/v2_upgrade>:
* Liquibase stores checksums for each change executed in the DATABASECHANGELOG table. These checksums are used to alert the user to changeSets that have been changed after they were executed, and to handle runOnChange=“true” changeSets. The way we compute these checksums changed in 2.0. The first time you update an existing database, Liquibase will detect the old format and upgrade the checksum values. During this first run, Liquibase will not be able to detect modified changeSets or runOnChange requirements. If you are concerned about this, you may want to run a known unchanged changelog against the database with 2.0 before updating your new changelog. * But I'm not sure if that'll help... I've tried replicating how that error happens, but the checksum generation today seems so quick that I'm unable to stop in its tracks. :| and things are working fine --- Regards, Saptarshi PURKAYASTHA My Tech Blog: http://sunnytalkstech.blogspot.com You Live by CHOICE, Not by CHANCE On 14 September 2011 17:48, Ben Wolfe <[email protected]> wrote: > Is there a way to replicate this and then write something to prevent > it Saptarshi? > > Ben > > On Wed, Sep 14, 2011 at 5:25 AM, Saptarshi Purkayastha <[email protected]> > wrote: > > I'm afraid I've seen this after the liquibase 2.0 upgrade fairly often > > because of the ways in which checksum generation has changed... > > This has happened to me when the installation/upgrade has not completed > > correctly... and then on resuming the upgrade/installation, this error is > > thrown > > Joel, did your installation/upgrade stop prematurely before?? > > --- > > Regards, > > Saptarshi PURKAYASTHA > > > > My Tech Blog: http://sunnytalkstech.blogspot.com > > You Live by CHOICE, Not by CHANCE > > > > > > On 14 September 2011 07:38, Joel Tellez <[email protected]> wrote: > >> > >> Hello all, I just wanted to let you know that I tried starting the app > >> and I received the following message. > >> > >> ERROR - Listener.contextInitialized(154) |2011-09-13 18:41:06,725| Got > >> exception while starting up: > >> java.lang.RuntimeException: Error occurred while trying to get the > >> updates needed for the database.
