Error description
Some runtimes are missing, not the same ones after restarting the server. The Liberty ffdc/ directory contains exception stack traces like this one : java.nio.channels.OverlappingFileLockException at sun.nio.ch.SharedFileLockTable.checkList(FileLockTable.java:267) at sun.nio.ch.SharedFileLockTable.add(FileLockTable.java:164) at sun.nio.ch.FileChannelImpl.lock(FileChannelImpl.java:1052) at java.nio.channels.FileChannel.lock(FileChannel.java:1064) at com.ibm.db2.jcc.am.pp.a(pp.java:685) at com.ibm.db2.jcc.am.op.a(op.java:455) at com.ibm.db2.jcc.am.op.a(op.java:527) at com.ibm.db2.jcc.am.Connection.isLicenseValidatedWithServerLicens eProc(Connection.java:8706) at com.ibm.db2.jcc.am.Connection.checkForLicenseRestrictions(Connec tion.java:4911) at com.ibm.db2.jcc.am.Connection.completeConnect(Connection.java:48 54) at com.ibm.db2.jcc.t4.b.completeConnect(b.java:614) at com.ibm.db2.jcc.t4.b.a(b.java:425) at com.ibm.db2.jcc.t4.b.a(b.java:397) at com.ibm.db2.jcc.t4.b.<init>(b.java:335) at com.ibm.db2.jcc.DB2PooledConnection.<init>(DB2PooledConnection.j ava:83) at com.ibm.db2.jcc.DB2ConnectionPoolDataSource.getPooledConnectionX (DB2ConnectionPoolDataSource.java:348) at com.ibm.db2.jcc.DB2ConnectionPoolDataSource.getPooledConnection( DB2ConnectionPoolDataSource.java:131) at com.ibm.ws.rsadapter.spi.InternalGenericDataStoreHelper$1.run(In ternalGenericDataStoreHelper.java:1195) at java.security.AccessController.doPrivileged(AccessController.jav a:559) at com.ibm.ws.rsadapter.spi.InternalGenericDataStoreHelper.getPoole dConnection(InternalGenericDataStoreHelper.java:1211) at com.ibm.ws.rsadapter.spi.InternalDB2UniversalDataStoreHelper.get PooledConnection(InternalDB2UniversalDataStoreHelper.java:1510) at com.ibm.ws.rsadapter.spi.WSRdbDataSource.getPooledConnection(WSR dbDataSource.java:331) at com.ibm.ws.rsadapter.spi.WSManagedConnectionFactoryImpl.getConne ction(WSManagedConnectionFactoryImpl.java:1182) at com.ibm.ws.rsadapter.spi.WSManagedConnectionFactoryImpl.createMa nagedConnection(WSManagedConnectionFactoryImpl.java:932) at com.ibm.ws.rsadapter.spi.WSManagedConnectionFactoryImpl.createMa nagedConnection(WSManagedConnectionFactoryImpl.java:617) at com.ibm.ejs.j2c.FreePool.createManagedConnectionWithMCWrapper(Fr eePool.java:1768) at com.ibm.ejs.j2c.FreePool.createOrWaitForConnection(FreePool.java :1512) at com.ibm.ejs.j2c.PoolManager.reserve(PoolManager.java:2989) at com.ibm.ejs.j2c.PoolManager.reserve(PoolManager.java:2341) at com.ibm.ejs.j2c.ConnectionManager.allocateMCWrapper(ConnectionMa nager.java:1109) at com.ibm.ejs.j2c.ConnectionManager.allocateConnection(ConnectionM anager.java:676) at com.ibm.ws.rsadapter.jdbc.WSJdbcDataSource.getConnection(WSJdbcD ataSource.java:354) at com.ibm.ws.rsadapter.jdbc.WSJdbcDataSource.getConnection(WSJdbcD ataSource.java:325) at com.worklight.server.database.api.WorklightDataSource.createReso urceRefDataSource(WorklightDataSource.java:181) at com.worklight.server.database.api.WorklightDataSource.discoverDB Type(WorklightDataSource.java:133) at com.worklight.server.database.api.WorklightDataSource.afterPrope rtiesSet(WorklightDataSource.java:93) at org.springframework.beans.factory.support.AbstractAutowireCapabl eBeanFactory.invokeInitMethods(AbstractAutowireCapableBeanFactor y.java:1573) at org.springframework.beans.factory.support.AbstractAutowireCapabl eBeanFactory.initializeBean(AbstractAutowireCapableBeanFactory.j ava:1511) at org.springframework.beans.factory.support.AbstractAutowireCapabl eBeanFactory.doCreateBean(AbstractAutowireCapableBeanFactory.jav a:521) at org.springframework.beans.factory.support.AbstractAutowireCapabl eBeanFactory.createBean(AbstractAutowireCapableBeanFactory.java: 458)

Problem conclusion
If each DB2 data source references its own JDBC driver shared Library, the DB2 connection can fail. To avoid this issue, in each MobileFirst ant tasks that install, update, uninstall the components (runtime, administration services) add the following property in the <websphereapplicationserver> element inside the <applicationserver> element : libertyShareJDBCDrivers="true" In this case all the data sources will reference the same JDBC driver shared library.
