Re: [aerogear-dev] AG UPS deadlock

Hi, we use two AG unified push servers with Oracle DB in cluster, but we have some problem with deadlock (probably caused by clean up by both servers at the same time). We used DB owner PUSHSRVAG and application DB account APUSHSRVAG. (version ... my fork (with small change in dev) ... https://github.com/IvanGurtler/aerogear-unifiedpush-server/tree/MyBranch) Is possible change some settings to prevent deadlock ? or some different solution ? ----------------------------------------------------------------------------------------- *** 2015-04-10 00:00:04.506 *** SESSION ID:(84.48937) 2015-04-10 00:00:04.506 *** CLIENT ID:() 2015-04-10 00:00:04.506 *** SERVICE NAME:(SYS$USERS) 2015-04-10 00:00:04.506 *** MODULE NAME:(JDBC Thin Client) 2015-04-10 00:00:04.506 *** CLIENT DRIVER:(jdbcthin) 2015-04-10 00:00:04.506 *** ACTION NAME:() 2015-04-10 00:00:04.506 *** 2015-04-10 00:00:04.506 DEADLOCK DETECTED ( ORA-00060 ) See Note 60.1 at My Oracle Support for Troubleshooting ORA-60 Errors [Transaction Deadlock] The following deadlock is not an ORACLE error.
