Hi, First of all, yes I know Apache Ignite not support SQL Transaction. I hope this is not showstopper of my POC. I`m here to find another way.
1. I have function for update sequence table. private int sequenceManual(String seqName) { int seq = 0; Query query; try { query = this.em.createNativeQuery("UPDATE SEQUENCE SET SEQ_COUNT = SEQ_COUNT + " + INCREMENT + " WHERE SEQ_NAME = '" +seqName+"'"); seq = (Integer) query.executeUpdate(); } catch (Exception e) { LOG.error("An exception was thrown while Update Sequence " + seqName, e); } try { query = this.em.createNativeQuery("SELECT SEQ_COUNT FROM SEQUENCE WHERE SEQ_NAME = '"+ seqName +"'"); seq = (int) ((Number) query.getSingleResult()).longValue(); } catch (Exception e) { LOG.error("An exception was thrown while Next Return Sequence " + seqName, e); } return seq; } with this code, I have an error: javax.persistence.TransactionRequiredException: Exception Description: No transaction is currently active Then, I modified my code with @Transactional Spring. @Transactional(propagation=Propagation.REQUIRED) private int sequenceManual(String seqName) { . . . . I have an error: java.lang.IllegalStateException: Not allowed to create transaction on shared EntityManager - use Spring transactions or EJB CMT instead Is there something suggestion to running my Update Sequence SQL? -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
