  +--com.adventnet.snmp.beans.SnmpServer

All Implemented Interfaces:

java.io.Serializable

Direct Known Subclasses:

SnmpRequestServer, SnmpTarget

public class SnmpServer

extends java.lang.Object

implements java.io.Serializable

This class maintains all the resources required for Snmp manager applications and applets. The resources are like SnmpAPI, SnmpSession, MibOperations and etc.The beans component like SnmpTarget and SnmpRequestServer extends this class. For every instance of these beans the SnmpServer uses the same resources.

setSerializeMibs

public void setSerializeMibs(boolean flag)

Defines whether to serialize the MibModule. This flag should be set before loading the MIBs. If this is set to true it will serialize the loaded MIBs. For ex: if RMON2-MIB is loaded, it will serialize this module along with the Imported Modules viz ., RFC1271-MIB,RFC1213-MIB,TOKEN-RING-RMON and saves it in a single file.The name of the serialized file can be set using the setSerializedMibFileName() method. In case,if serialized file name is not set,it will save the serialized file with the MIB file name along with ".ser" extention.Here, it will save it as RMON2-MIB.ser. Serialization is not supported in applets.

isSerializeMibs

public boolean isSerializeMibs()

Returns whether the mib file will be serialized or not.

setLoadFromSerializedMibs

public void setLoadFromSerializedMibs(boolean flag)

Method defines whether to load MIB from serialized file. This flag should be set before loading the MIBs. If both serializeMibs and loadFromSerializedMibs are set to true, it will just try to load the MIB as a serialized file.

setLoadFromCompiledMibs

public void setLoadFromCompiledMibs(boolean flag)

Defines whether to load mib from compiled MIBs. This flag should be set before loading the MIBs (By default it is set to false). If this flag is set to true, it will load from compiled file( i.e; .cmi and .cds files). For ex: RMON2-MIB is loaded, it will automatically load RMON2-MIB.cmi if it exists. otherwise it creates compiled files by parsing and then loads from it. If this flag is set to false, the mib is loaded without creating .cmi and .cds files. This is recommended in case of applets where you have security restrictions for file creation. This is slightly slower than loading from precompiled mibs. In Applets, precompiled mibs can be loaded but it cannot create/write compiled files.

If both loadFromSerializedMibs and loadFromCompiledMibs is set to true, it will just try to load the MIB as a serialized file.

setLoadMibsFromDatabase

public void setLoadMibsFromDatabase(boolean flag)

Defines whether to load mib from DataBase. The Jdbc Parameters should be set, using the initJdbcParams(), before calling this method. This flag should be set before loading the MIBs (By default it is set to false). If this flag is set to true, it will parse the mibs,and store it in the database. For ex: RMON2-MIB is loaded, it will parse the mib and store it in the database.

Parameters:

flag - boolean
