removeClientPool

public static void removeClientPool(java.lang.String key)
Delete a client pool from the pool list.
Note: The routine will close all open connections of the specified pool forcefully, before the pool is being removed.
Parameters:
key - the name of the pool

getClient

public static JCO.Client getClient(java.lang.String key)
Returns a client connection from the specified pool.
If no clients are available in pool, pool will wait max max_wait_time ms until an other thread releases a client. If no clients are released during the waiting and a client could not be allocated, a pool throws JCO.Exception with the error group set to JCO.Exception.JCO_ERROR_RESOURCE.
Parameters:
key - the name of the pool from which to take the connection from
Returns:
a client connection from the specified pool or null
Throws:
JCO.Exception - with the error group set to JCO.Exception.JCO_ERROR_RESOURCE, if a client could not be allocated, i.e. the client pool is exhausted
JCO.Exception - thrown if a client connection could not be established due to wrong logon data, network problems, etc.
See Also:
JCO.PoolManager.setMaxWaitTime(long), Note: Any client obtained by this method must be released with JCO.releaseClient(), releaseClient(com.sap.mw.jco.JCO.Client)

getClient

public static JCO.Client getClient(java.lang.String key,
                                   boolean reset)
Returns a client connection from the specified pool.
Note: Any client obtained by this method must be released with JCO.releaseClient()
Parameters:
key - the name of the pool from which to take the connection from
reset - if true reset the connection, e.g. free all resources that might have been allocated on either the server side or by the local middleware library. On systems below SAP system 4.0A resetting a connection effectively means closing and subsequently reopening the connection which is a very expensive process. However, several scenarios (e.g. BAPIs) might need such reinitialized connections.
JCO.releaseClient(Client client) will reset the connection automatically.
Returns:
a client connection from the specified pool or null
Throws:
JCO.Exception - with the error group set to JCO.Exception.JCO_ERROR_RESOURCE, if a client could not be allocated, i.e. the client pool is exhausted
JCO.Exception - thrown if a client connection could not be established due to wrong logon data, network problems, etc.
See Also:
releaseClient(com.sap.mw.jco.JCO.Client)

releaseClient

public static void releaseClient(JCO.Client client)
Releases a client connection to its pool.
It is neccessary to release all client connections that are obtained with JCO.getClient(). Otherwise the pool will run out of connections at some time. As a result a JCO.Exception of the groupJCO_ERROR_RESOURCE will be thrown by the JCO.getClient() method. 
The pool checks the client and decides to put it back to the cache or to remove it. 
Note: After releasing a JCO.Client instance with this method you have to clear all references to it. Otherwise there will be a JCO.Exception thrown if it used once again. 
On SAP systems equal or above 4.0A the method resets the connection, i.e. frees all resources and context allocated on the server side (i.e. '/n' in SAP system) or by the local middleware layer.
Parameters:
client - the client to be released to the pool
Throws:
JCO.Exception - thrown if a connection could not be released cleanly
See Also:
getClient(java.lang.String), JCO.Pool.setResetOnRelease(boolean)

createParameterList

public static JCO.ParameterList createParameterList()
Returns a newly created parameter list
