我们在一个Servlet容器上使用Xodus,应用时不时抛出这个错误(不知道是什么原因)
jetbrains.exodus.ExodusException: Can't acquire environment lock after 0 ms.
Lock owner info:
null
at jetbrains.exodus.log.Log.tryLock(Log.java:935)
at jetbrains.exodus.log.Log.<init>(Log.java:91)
at jetbrains.exodus.env.Environments.newLogInstance(Environments.java:137)
at jetbrains.exodus.env.Environments.newLogInstance(Environments.java:115)
at jetbrains.exodus.env.Environments.newLogInstance(Environments.java:104)
at jetbrains.exodus.env.Environments.newInstance(Environments.java:49)
at jetbrains.exodus.env.Environments.newInstance(Environments.java:39)
什么可能导致这种情况发生?
示例用法:
public void put(String instance, final String storeName, final String key, final String value) {
final Environment env = Environments.newInstance(xodusRoot + instance);
env.executeInTransaction(new TransactionalExecutable() {
@Override
public void execute(@NotNull final Transaction txn) {
final Store store = env.openStore(storeName, StoreConfig.WITHOUT_DUPLICATES, txn);
store.put(txn, StringBinding.stringToEntry(key), StringBinding.stringToEntry(value));
}
});
env.close();
}
如果这put方法是从一个Servlet端点调用,服务器因此多个并发客户端调用此方法。
