the other session to proceed. In doing so, a trace file for the offending session is created in a directory based on the value for the user_dump_dest initialization parameter.While compressing a versioned geodatabase, the compress command may potentially encounter the Oracle error "ORA-00060: deadlock detected while waiting for resource". Cause If encountering the Oracle error during a compress, the deadlock being encountered is not the customary type of ora-00060 deadlock detected while waiting for resource in datastage deadlock where two sessions are competing/blocking requests for the same row objects to update or delete, but blocking for the ITL slots in a segment's block header.For a very detailed description of the issue, review Oracle Metalink document 62354.1 "TX Transaction locks - Example wait scenarios" under the section, "Waits due to Insufficient 'ITL' slots in a Block".The blocking condition being encountered is likely to be on either the state_lineages table or on one of its two indexes: lineages_pk or lineage__id_idx2.The error typically only manifests itself when a compress is executed while a high number of users are concurrently editing the versioned geodatabase. Solution or Workaround To resolve the deadlocking error, the SDE user must re-create the state_lineage table indexes or table and increase the value for the number of initial transaction slots in the objects block's header.By default, ArcGIS sets the initrans value to 4 when creating all the tables and indexes used by versioning. The initrans value is controlled in the dbtune.sde file under the keyword DATA_DICTIONARY, but is only referenced when the instance is initially created.To increase the initrans value for the indexes, the SDE user rebuilds the index and specifies the new value.Code:SQL> ALTER INDEX lineages_pk REBUILD INITRANS 8;Inde

Description When https://www.techonthenet.com/oracle/errors/ora00060.php you encounter an ORA-00060 error, the following error message will appear: ORA-00060: deadlock detected while waiting for resource Cause You tried to execute a statement, but your session was deadlocked because another session had the same resource locked. The statement(s) that you tried to execute have been rolled back. Resolution The option(s) to resolve this Oracle error are: Option #1 You can wait a few minutes and try to re-execute the statement(s) that were rolled back. Option #2 You can execute a ROLLBACK and re-execute all statements since the last COMMIT was executed.

These scripts are written by somebody else and are meant to be executed concurrently. All the scripts 00060 deadlock detected are performing updates on a table. I am getting the error, ORA-00060: deadlock detected while waiting for resource As I googled for this, I found, http://www.dba-oracle.com/t_deadly_perpetual_embrace_locks.htm Even though the scripts are performing updation on the same table concurrently, they are performing updates on different records of the table determined by the WHERE clause with no overlaps of records between them. So would this have caused the error?. Will this error happen regardless of where the updates are performed on a table?. Should I avoid concurrent updates on a table at all times?. Strangely I also found on the nohup.out log, PL/SQL successfully completed after the above quoted error. Does this mean that oracle has recovered from the deadlock and completed the updates successfully or Should I rerun those scripts serially? Any help would be welcome. Thanks in advance. database oracle unix plsql aix share|improve this question edited Dec 15 '14 at 21:20 Lajos Veres 10.8k72346 asked Jun 19 '10 at 8:00 wowrt 242238 add a comment| 3 Answers 3 active oldest votes up vote
Further information What are deadlocks? A deadlock is the situation where you have two, or more, Oracle "sessions" (well, transactional "states") competing for mutually locked resources. Oracle deals with deadlocks pretty much immediately by raising an exception (ORA-00060) in one of the sessions. There are a few reasons why your application may experience deadlocks, most of which are about application design. However, there are a few situations when, due to certain architectural design decisions, you may experience deadlocks simply due to the internal mechanisms of Oracle itself. The "classic" deadlock If session 1 is locking row 1, session 2 locks row 2, then session 1 attempts to lock row 2 (which will block since session 2 has the lock on that row), and then session 2 attempts to lock row 1 (which will block since session 1 has the lock on that row), then session 1 is waiting for session 2, and session 2 is waiting on session 1, which of course will never be resolved. Here's an actual Oracle example. First of all, setup the environment : SQL> CREATE TABLE t ( a varchar2(10) ); Table created. SQL> insert into t values ( 'x' ); 1 row created. SQL> insert into t values ( 'y' ); 1 row created. SQL> commit; Commit complete. Now, session 1 attempts to delete row 'x', but doesn't commit : SESS1> delete from t where a = 'x'; 1 row deleted. Okay, now session 2 attempts to delete row 'y', again, not committing : SESS2> delete from t where a = 'y'; 1 row deleted. Now, since session 2 has not committed the delete against row 'y', session 1 can still "see" it (and attempt to delete it) : SESS1> delete from t where a = 'y'; However, this will be blocked by session 2 (and hence wait), since row 'y' is locked, so session 1 is holding the lock on row 'x' but is waiting for row 'y'. Now, session 2 attempts to do it the "other way around", i.e. attempting to delete row 'x', while it retains the lock on row 'y' : SESS2> delete from t where a = 'x'; this will be blocked by session 1 (and hence wait). So, the situation is tied, session 2 is waiting for session 1 and session 1 is waiting for session 2. So, in reality, what happens in this situation? Well, obviously deadlocks just simply can't be allowed to occur, it's basically an infinite loop, the
