java to get the name of the instance for a db on the local host
(uses shell script similar to the srvcheck solution)

import java.net.InetAddress;

import oracle.ops.mgmt.database.Instance;
import oracle.ops.mgmt.database.ParallelServerConfig;
import oracle.ops.mgmt.operation.GetConfigurationOperation;
import oracle.ops.mgmt.operation.GetConfigurationResult;

public class ClusterLocalInstance {
private static final String USAGE = "checks to see name of local instance for provided db name";

java to quickly list rac dbs or check if a db is in the rac db list

import oracle.ops.mgmt.operation.ListParallelServersOperation;
import oracle.ops.mgmt.operation.ListParallelServersResult;

public class ClusterCheck {

private static final String USAGE = "  no args lists all cluster dbs\n  1 arg checks to see if that db is clustered";

Metalink article 262353.1

essentially

select count (distinct dbms_rowid.rowid_block_number(r.rowid)) "used blocks", blocks "below hwm", empty_blocks "above hwm"
from <table_name> r, dba_tables
where table_name = '<table_name>'
group by blocks, empty_blocks;

copy /b SrcFile1+SrcFile2 [+SrcFileN] DestnFile

seems fairly obvious really!

the class you've specified cannot be loaded - you're not being silly and trying to load an abstract class are you?
