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.
|
40 r.kieninger 1.3
|
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 1.8 There is a new environment variable that tells the JVM to output more debugging information. The variable name
|
83 mark.hamzy 1.6 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 mark.hamzy 1.8 Unloading of idle providers is not supported and Java will increase the memory footprint.
|
98 schuur 1.1
99
100 poststarttests
101
|
102 mark.hamzy 1.8 This installment has a set of tests modelled after wetest/static.
103 For the tests, I had to modify "diff" to "diff -w", why that is needed I do not understand.
|
104 schuur 1.1
105
106 Building poststarttests:
107
108 cd to .../src/Pegasus/ProviderManager2/JMPI/org/pegasus/jmpi/tests/Load
109 Issue "make"
110
111 This will load a schema to the repository and register the provider.
112
113
114 Running poststarttests:
115
116 cd to .../src/Pegasus/ProviderManager2/JMPI/org/pegasus/jmpi/tests
117 Issue "find -name "*.rsp" -exec rm {} \;" to clean up *.rsp files
118 Issue "make poststarttests"
119
120
121 Samples
122
123 The provider used for posstarttest,
124 .../JMPI/org/pegasus/jmpi/test/JMPI_TestPropertyTypes/JMPI_TestPropertyTest.java is a working
125 schuur 1.1 example of how to code an JMPI tyle instance provider.
126 This directors also constains the required Makefile.
127
128 .../JMPI/org/pegasus/jmpi/sample contains more samples, one of which is an incomplete CIMClient
129 sample.
130
131 Notice that all provider classes must be accessibe via the CASSPATH environment setting.
132
133
134 Provider Registration
135
136 JMPI providers are registered as usual. The Location property in P_ProviderModule has a special format.
137 The format is: <jar-file-name>:<provider-class-name>
138
139 instance of PG_ProviderModule
140 {
141 Name = "JMPI_TestPropertyTypesModule";
|
142 mark.hamzy 1.8 Location = "JMPI_TestPropertyTypes.jar:org/pegasus/jmpi/tests/JMPI_TestPropertyTypes/JMPI_TestPropertyTypes";
|
143 schuur 1.1 Vendor = "Pegasus Community";
144 Version = "2.0.0";
145 InterfaceType = "JMPI";
146 InterfaceVersion = "1.0.0";
147 };
148
|
149 mark.hamzy 1.8 JMPI providers now fall into two groups.
150 1) Legacy providers use:
151 InterfaceType = "JMPI"
152 and use one of the 3 following based on existing JMPI samples:
153 InterfaceVersion = "1.0.0";
154 InterfaceVersion = "2.0.0";
155 InterfaceVersion = "2.2.0";
156 Note that there is no difference in behavior in the three versions.
157 2) New style providers use:
158 InterfaceType = "JMPIExperimental"
159 and:
160 InterfaceVersion = "0.0.1";

163 Bug reports
164
|
165 r.kieninger 1.3 Use normal Pegasus bugzilla procedures to report malfunctions.
