32 mark.hamzy 1.9 Java Manageability Programming Interface (JMPI)
33 -----------------------------------------------
|
34 schuur 1.1
|
35 mark.hamzy 1.9 JMPI is a bridge between clients and providers written in Java and the Open
36 Pegasus project.
|
37 schuur 1.1
|
38 mark.hamzy 1.9 More information on JMPI's status can be found at
39 http://www.openpegasus.org/page.tpl?ggid=799

42 Environment settings
|
43 mark.hamzy 1.9 --------------------
|
44 schuur 1.1
|
45 mark.hamzy 1.9 In order to build this support a few environment variables have to used.
46 The following script has been proven useful for setting up the build and execution environment.
47 You might need to adjust this to your system layout.
|
48 schuur 1.1
|
49 mark.hamzy 1.9 an example setJPeg script file:
|
50 schuur 1.1 export PEGASUS_HOME=`pwd`
|
51 mark.hamzy 1.9 export PEGASUS_ROOT=${PEGASUS_HOME}
|
52 schuur 1.1 export PEGASUS_PLATFORM=LINUX_IX86_GNU
|
53 mark.hamzy 1.9 export PEGASUS_ENABLE_JMPI_PROVIDER_MANAGER=true
|
54 schuur 1.1 export PEGASUS_DEBUG=1
|
55 mark.hamzy 1.9 export JAVA_SDK=/usr/java/j2sdk1.4.2_08
56 export JAVA_SDKINC=${JAVA_SDK}/include
57 export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:${JAVA_SDK}/jre/lib/i386/server:${JAVA_SDK}/jre/lib/i386/native_threads:${JAVA_SDK}/jre/lib/i386
58 export PATH=${JAVA_SDK}/bin/:${PEGASUS_HOME}/bin:${PATH}
59 export CLASSPATH=${CLASSPATH}:${PEGASUS_HOME}/lib/JMPIImpl.jar
60
61 There is now a new variable to determine which JVM to link with. The choices are as follows:
|
62 mark.hamzy 1.11 PEGASUS_JVM gcj Gnu's jvm (ex: gij (GNU libgcj) version 4.1.1 20060525 (Red Hat 4.1.1-1))
|
63 mark.hamzy 1.9 PEGASUS_JVM sun Sun's jvm (ex: j2sdk1.4.2_07)
64 PEGASUS_JVM ibm IBM's jvm (ex: IBMJava2-142)
65 PEGASUS_JVM bea Suse's IBM jvm (ex: BEAJava2-1.4.2)
66 So, pick one and export that variable to the environment. For example,
67 export PEGASUS_JVM=sun
|
68 mark.hamzy 1.11 NOTE: The gcj and sun options were the only tested JVMs.
|
69 schuur 1.1
|
70 mark.hamzy 1.9 There are a couple of optional environment variables to determine how the JRE is initialized. These are
71 as follows (the variable name and what JRE option that it corresponds to):
|
72 mark.hamzy 1.5
|
73 mark.hamzy 1.9 PEGASUS_JMPI_MAX_HEAP -Xmx
74 PEGASUS_JMPI_INITIAL_HEAP -Xms
75 PEGASUS_JMPI_JAVA_THREAD_STACK_SIZE -Xss
|
76 mark.hamzy 1.4
|
77 mark.hamzy 1.9 So, for example, you would perform the following if you want to change the maximum heap size to 128 megabytes.
|
78 mark.hamzy 1.4
|
79 mark.hamzy 1.9 export PEGASUS_JMPI_MAX_HEAP=128m
|
80 mark.hamzy 1.4
|
81 mark.hamzy 1.9 There is a new optional environment variable that tells the JVM to output more debugging information. The variable name
82 is called PEGASUS_JMPI_VERBOSE. An example usage is as follows:
|
83 mark.hamzy 1.4
|
84 mark.hamzy 1.9 export PEGASUS_JMPI_VERBOSE="jni,class"
|
85 mark.hamzy 1.6
|
86 mark.hamzy 1.9 This will tell the JVM to output debug information on the JNI layer and class loading.
|
87 mark.hamzy 1.6
|
88 mark.hamzy 1.9 When using this script, place a copy of this script above your PEGASUS_HOME directory.
89 "cd" to PEGASUS_HOME, and issue ". ./setJPeg". Then do a normal make.

92 mark.hamzy 1.9 Known restrictions
93 ------------------
|
94 schuur 1.1
|
95 mark.hamzy 1.9 This installment has the following restrictios:
|
96 schuur 1.1
|
97 mark.hamzy 1.8 Unloading of idle providers is not supported and Java will increase the memory footprint.
|
98 mark.hamzy 1.9 Java 1.5 is not currently supported.
99
100
101 Level of coverage
102 -----------------
103
104 All interfaces to a provider have a sample provider written for them and are part of the
105 testcases. All main CIM java classes have testcases written for them as well.
106
107
108 Outstanding issues
109 ------------------
110
111 Java documentation needs to be written for the classes and methods within JMPI.
112
113
114 Testing
115 -------
116
117 This installment has a set of tests located under src/Pegasus/ProviderManager2/JMPI/org/pegasus/jmpi/tests/
|
118 schuur 1.1
|
119 mark.hamzy 1.9 Static/
|
120 schuur 1.1
|
121 mark.hamzy 1.9 These tests have been modelled after wetest/static.
122 For the tests, I had to modify "diff" to "diff -w", why that is needed I do not understand.
|
123 schuur 1.1
|
124 mark.hamzy 1.9 Providers/
|
125 schuur 1.1
|
126 mark.hamzy 1.9 These tests implement the many variants of provider interfaces.

|
128 mark.hamzy 1.9 Client/
|
129 schuur 1.1
|
130 mark.hamzy 1.9 These tests test out the client code and various Java classes.

133 Running the tests
134 -----------------
135
136 Tests are run with the following process.
137 If the repository has not been built before then issue the following:
138
139 cd to ${PEGASUS_HOME}/src/Pegasus/ProviderManager2/JMPI/
140 Issue "make repository"
|
141 schuur 1.1
142 This will load a schema to the repository and register the provider.
143
|
144 mark.hamzy 1.9 Next, run the tests.
|
145 schuur 1.1
|
146 mark.hamzy 1.9 cd to ${PEGASUS_HOME}/src/Pegasus/ProviderManager2/JMPI/
147 Issue "find -name \*.rsp -exec rm {} \;" to clean up *.rsp files from failed tests.
|
148 schuur 1.1 Issue "make poststarttests"
149

151 Samples
|
152 mark.hamzy 1.9 -------
153
154 There are four sample providers located in
155 ${PEGASUS_HOME}/src/Pegasus/ProviderManager2/JMPI/org/pegasus/jmpi/tests/Providers/
156
157 Associations/
158
159 This provider implements an association provider.

163 This provider implements an instance provider.

|
170 schuur 1.1
|
171 mark.hamzy 1.9 This provider implements a property provider.
172
173 There is also sample Java code that deals with CIM classes that is located in
174 ${PEGASUS_HOME}/src/Pegasus/ProviderManager2/JMPI/org/pegasus/jmpi/tests/Client/

177 Provider Registration
|
178 mark.hamzy 1.9 ---------------------
|
179 schuur 1.1
|
180 mark.hamzy 1.9 JMPI providers are registered as usual. The Location property in PG_ProviderModule has a special format.
|
181 schuur 1.1 The format is: <jar-file-name>:<provider-class-name>
182
|
183 mark.hamzy 1.8 JMPI providers now fall into two groups.
184 1) Legacy providers use:
185 InterfaceType = "JMPI"
186 and use one of the 3 following based on existing JMPI samples:
187 InterfaceVersion = "1.0.0";
188 InterfaceVersion = "2.0.0";
189 InterfaceVersion = "2.2.0";
190 Note that there is no difference in behavior in the three versions.
|
191 mark.hamzy 1.9
192 instance of PG_ProviderModule
193 {
194 Name = "JMPIInstanceProviderModule";
195 Location = "JMPIInstanceProvider.jar:Instances/JMPIInstanceProvider";
196 Vendor = "OpenPegasus";
197 Version = "2.0.0";
198 InterfaceType = "JMPI";
199 InterfaceVersion = "1.0.0";
200 };
201
|
202 mark.hamzy 1.8 2) New style providers use:
203 InterfaceType = "JMPIExperimental"
204 and:
205 InterfaceVersion = "0.0.1";
206
|
207 mark.hamzy 1.9 instance of PG_ProviderModule
208 {
209 Name = "JMPIExpInstanceProviderModule";
210 Location = "JMPIExpInstanceProvider.jar:Instances/JMPIExpInstanceProvider";
211 Vendor = "OpenPegasus";
212 Version = "2.0.0";
213 InterfaceType = "JMPIExperimental";
214 InterfaceVersion = "0.0.1";
