I recently had to implement a scanner system to interact with java. ... using a keyboard hook (to use the barcodes as variables in java, as you mentioned). ... JNI coding but I wasn't prepared to take the time to work out the native code. ... Here's a somewhat stripped down version of my barcode reader class: The ORA-00054 message is a confusing message at first, since there is no direct method to specify NOWAIT or WAIT on a DROP TABLE at all. It is just the generic message you get when you attempt to perform an operation that would be blocked, but the operation does not permit blocking. As you ve seen before, it s the same message you get if you issue a SELECT FOR UPDATE NOWAIT against a locked row. The following shows how these locks would appear in the V$LOCK table: ops$tkyte%ORA11GR2> create table t1 ( x int ); Table created. ops$tkyte%ORA11GR2> create table t2 ( x int ); Table created. ops$tkyte%ORA11GR2> connect / Connected. ops$tkyte%ORA11GR2> insert into t1 values ( 1 ); 1 row created. ops$tkyte%ORA11GR2> insert into t2 values ( 1 ); 1 row created. ops$tkyte%ORA11GR2> select (select username 2 from v$session 3 where sid = v$lock.sid) username, 4 sid, 5 id1, 6 id2, 7 lmode, 8 request, block, v$lock.type 9 from v$lock 10 where sid = (select sid Experts rely on hit ratios or wait statistics, or sometimes both, but there are situations in which both the hit ratios and the wait statistics can completely fail you. Imagine a situation where all the hit ratios are in the 99 percent range. Also, imagine that the wait statistics don t show any significant waiting for resources or any contention for latches. Does this mean that your system is running optimally Well, your system is doing what you asked it to do extremely well, but there s no guarantee that your SQL code is processing things efficiently. If a query is performing an inordinate number of logical reads, the hit ratios are going to look wonderful. The wait events also won t show you a whole lot, because they don t capture the time spent while you were actually using the CPU. However, you ll be burning a lot of CPU time, because the query is making too many logical reads. This example shows why it s important not to rely only on the hit ratios or the wait statistics, but also to look at the major consumers of resources on your instance with an intense focus. Check the Top Sessions list (sorted according to different criteria) on your instance and see if there s justification for the major consumers to be in that list. java barcode reader library open source zxing/zxing: ZXing ("Zebra Crossing") barcode scanning ... - GitHub
