 32            Java Manageability Programming Interface - JMPI
 33            
 34            Author: Adrian Schuur, schuur@de.ibm.com  - 30 Apr 2004 -
 35            
 36            First installment
 37            
 38               This installment of JMPI has been committed to the 2.4 branch.
 39               This installment has been build and tested on Suse 9.0 with Sun's j2sdk 1.4.2_04.

 41 schuur      1.1 
 42                 Environment settings
 43                 
 44                    In order to build this support a few environment variables have to used.
 45                    The following script has been proven useful for setting up the build and execution environment.
 46                    You might need to adjust this to your system layout.
 47                 
 48                    export PEGASUS_HOME=`pwd`
 49                    export PEGASUS_PLATFORM=LINUX_IX86_GNU
 50 konrad.r    1.2    export PEGASUS_ENABLE_CMPI_PROVIDER_MANAGER=1
 51                    export PEGASUS_ENABLE_JMPI_PROVIDER_MANAGER=1
 52 schuur      1.1    export PEGASUS_DEBUG=1
 53                    export JAVA_SDK=/usr/java/j2sdk1.4.2_04
 54                    export JAVA_SDKINC=$JAVA_SDK/include
 55                    export LD_LIBRARY_PATH=$PEGASUS_HOME/lib:$JAVA_SDK/jre/lib/i386/server:$JAVA_SDK/jre/lib/i386/native_threads:$JAVA_SDK/jre/lib/i386
 56                    export PATH=$JAVA_SDK/bin:$PATH
 57 r.kieninger 1.3    export CLASSPATH=$PEGASUS_ROOT/src/Pegasus/ProviderManager2/JMPI
 58 schuur      1.1    export PATH=$PEGASUS_HOME/bin:$PATH
 59                    export PEGASUS_ROOT=$PEGASUS_HOME
 60                    export LD_ASSUME_KERNEL=2.2.5
 61                    cd $PEGASUS_HOME
 62                 
 63 mark.hamzy  1.5    There is now a new variable to determine which JVM to link with.  The choices are as follows:
 64                 	PEGASUS_JVM	sun	Sun's jvm (ex: j2sdk1.4.2_07)
 65                 	PEGASUS_JVM	ibm	IBM's jvm (ex: IBMJava2-142)
 66                 	PEGASUS_JVM	bea	Suse's IBM jvm (ex: BEAJava2-1.4.2)
 67                    So, pick one and export that variable to the environment.  For example,
 68                 	export PEGASUS_JVM=sun
 69                    NOTE: This is currently listened to for Linux builds.
 70                 
 71 mark.hamzy  1.4    There are a couple of optional environment variables to determine how the JRE is initialized.  These are
 72                    as follows (the variable name and what JRE option that it corresponds to):
 73                 
 74                    PEGASUS_JMPI_MAX_HEAP               -Xmx
 75                    PEGASUS_JMPI_INITIAL_HEAP           -Xms
 76                    PEGASUS_JMPI_JAVA_THREAD_STACK_SIZE -Xss
 77                 
 78                    So, for example, you would perform the following if you want to change the maximum heap size to 128 megabytes.
 79                 
 80                    export PEGASUS_JMPI_MAX_HEAP=128m
 81                 
 82 mark.hamzy  1.6    There is a new environment variable that tells the JVM to output more debugging information.  The variable name 
 83                    is called PEGASUS_JMPI_VERBOSE.  An example usage is as follows:
 84                 
 85                    export PEGASUS_JMPI_VERBOSE="jni,class"
 86                 
 87                    This will tell the JVM to output debug information on the JNI layer and class loading.
 88                 
 89 schuur      1.1    When using this script, place a copy of this script above your PEGASUS_HOME directory.
 90                    "cd" to PEGASUS_HOME, and issue ". ../setJPeg". Then do a normal make.
 91                 
 92                 
 93 mark.hamzy  1.4 This installment has a number of restrictios:
 94 schuur      1.1 
 95                    The provider interfaces follow the SNIA OpenWBEM APIs
 96                    Only Instance and Association providers are supported at the moment.
 97                 	SetProperty and GetProperty CIM operations will crash cimserver
 98                    Jar support is not yet implemented - all classes must be accessable via the CLASSPATH variabe.
 99                    The Makefiles are not yet Pegasus conforming.
100                 	cimmofl must be used for provider registration.
101                 
102                 	Unloading of idle providers is not supported and Java will increase the memory footprint.
103                 
104                 
105                 poststarttests
106                 
107                    This installment has a set of tests modelled after wetest/static. All tests work properly except
108                    the Property tests. I had to modify "diff" to "diff -w", why that is needed I do not understand.
109                 
110                 
111                 Building poststarttests:
112                 
113                    cd to .../src/Pegasus/ProviderManager2/JMPI/org/pegasus/jmpi/tests/Load
114                    Issue "make"
115 schuur      1.1 
116                    This will load a schema to the repository and register the provider.
117                 
118                 
119                 Running poststarttests:
120                 
121                    cd to .../src/Pegasus/ProviderManager2/JMPI/org/pegasus/jmpi/tests
122                    Issue "find -name "*.rsp" -exec rm {} \;" to clean up *.rsp files
123                    Issue "make poststarttests"
124                 
125                 
126                 Samples
127                 
128                    The provider used for posstarttest,
129                 	.../JMPI/org/pegasus/jmpi/test/JMPI_TestPropertyTypes/JMPI_TestPropertyTest.java is a working
130                 	example of how to code an JMPI tyle instance provider.
131                 	This directors also constains the required Makefile.
132                 
133                 	.../JMPI/org/pegasus/jmpi/sample contains more samples, one of which is an incomplete CIMClient
134                 	sample.
135                 
136 schuur      1.1 	Notice that all provider classes must be accessibe via the CASSPATH environment setting.
137                 
138                 
139                 Provider Registration
140                 
141                    JMPI providers are registered as usual. The Location property in P_ProviderModule has a special format.
142                 	The format is: <jar-file-name>:<provider-class-name>
143                 
144                 	Although jar support is not yet working correctly, this format must be used. You should use cimmofl
145                 	for registration untill cimmof is prepared for JMPI.
146                 
147                    instance of PG_ProviderModule
148                    {
149                       Name = "JMPI_TestPropertyTypesModule";
150                       Location = "JMPI_TestPropertyTypes.jar:"
151                 		           "org/pegasus/jmpi/tests/JMPI_TestPropertyTypes/JMPI_TestPropertyTypes";
152                       Vendor = "Pegasus Community";
153                       Version = "2.0.0";

155                       InterfaceVersion = "1.0.0";
156                    };
