6 First installment

8 This installment of JMPI has been committed to the 2.4 branch.
9 This installment has been build and tested on Suse 9.0 with Sun's j2sdk 1.4.2_04.

12 Environment settings
13
14 In order to build this support a few environment variables have to used.
15 The following script has been proven useful for setting up the build and execution environment.
16 You might need to adjust this to your system layout.
17
18 export PEGASUS_HOME=`pwd`
19 export PEGASUS_PLATFORM=LINUX_IX86_GNU
|
20 konrad.r 1.2 export PEGASUS_ENABLE_CMPI_PROVIDER_MANAGER=1
21 export PEGASUS_ENABLE_JMPI_PROVIDER_MANAGER=1
|
22 schuur 1.1 export PEGASUS_DEBUG=1
23 export JAVA_SDK=/usr/java/j2sdk1.4.2_04
24 export JAVA_SDKINC=$JAVA_SDK/include
25 export LD_LIBRARY_PATH=$PEGASUS_HOME/lib:$JAVA_SDK/jre/lib/i386/server:$JAVA_SDK/jre/lib/i386/native_threads:$JAVA_SDK/jre/lib/i386
26 export PATH=$JAVA_SDK/bin:$PATH

27 r.kieninger 1.3 export CLASSPATH=$PEGASUS_ROOT/src/Pegasus/ProviderManager2/JMPI
|
28 schuur 1.1 export PATH=$PEGASUS_HOME/bin:$PATH
29 export PEGASUS_ROOT=$PEGASUS_HOME
30 export LD_ASSUME_KERNEL=2.2.5
31 cd $PEGASUS_HOME

33 mark.hamzy 1.5 There is now a new variable to determine which JVM to link with. The choices are as follows:
34 PEGASUS_JVM sun Sun's jvm (ex: j2sdk1.4.2_07)
35 PEGASUS_JVM ibm IBM's jvm (ex: IBMJava2-142)
36 PEGASUS_JVM bea Suse's IBM jvm (ex: BEAJava2-1.4.2)
37 So, pick one and export that variable to the environment. For example,
38 export PEGASUS_JVM=sun
39 NOTE: This is currently listened to for Linux builds.

41 mark.hamzy 1.4 There are a couple of optional environment variables to determine how the JRE is initialized. These are
42 as follows (the variable name and what JRE option that it corresponds to):
43
44 PEGASUS_JMPI_MAX_HEAP -Xmx
45 PEGASUS_JMPI_INITIAL_HEAP -Xms
46 PEGASUS_JMPI_JAVA_THREAD_STACK_SIZE -Xss
47
48 So, for example, you would perform the following if you want to change the maximum heap size to 128 megabytes.
49
50 export PEGASUS_JMPI_MAX_HEAP=128m

52 schuur 1.1 When using this script, place a copy of this script above your PEGASUS_HOME directory.
53 "cd" to PEGASUS_HOME, and issue ". ../setJPeg". Then do a normal make.

56 mark.hamzy 1.4 This installment has a number of restrictios:
|
57 schuur 1.1
58 The provider interfaces follow the SNIA OpenWBEM APIs
59 Only Instance and Association providers are supported at the moment.
60 SetProperty and GetProperty CIM operations will crash cimserver
61 Jar support is not yet implemented - all classes must be accessable via the CLASSPATH variabe.
62 The Makefiles are not yet Pegasus conforming.
63 cimmofl must be used for provider registration.
64
65 Unloading of idle providers is not supported and Java will increase the memory footprint.
66
67
68 poststarttests
69
70 This installment has a set of tests modelled after wetest/static. All tests work properly except
71 the Property tests. I had to modify "diff" to "diff -w", why that is needed I do not understand.
72
73
74 Building poststarttests:
75
76 cd to .../src/Pegasus/ProviderManager2/JMPI/org/pegasus/jmpi/tests/Load
77 Issue "make"
78 schuur 1.1
79 This will load a schema to the repository and register the provider.
80
81
82 Running poststarttests:
83
84 cd to .../src/Pegasus/ProviderManager2/JMPI/org/pegasus/jmpi/tests
85 Issue "find -name "*.rsp" -exec rm {} \;" to clean up *.rsp files
86 Issue "make poststarttests"
87
88
89 Samples
90
91 The provider used for posstarttest,
92 .../JMPI/org/pegasus/jmpi/test/JMPI_TestPropertyTypes/JMPI_TestPropertyTest.java is a working
93 example of how to code an JMPI tyle instance provider.
94 This directors also constains the required Makefile.
95
96 .../JMPI/org/pegasus/jmpi/sample contains more samples, one of which is an incomplete CIMClient
97 sample.
98
99 schuur 1.1 Notice that all provider classes must be accessibe via the CASSPATH environment setting.
100
101
102 Provider Registration
103
104 JMPI providers are registered as usual. The Location property in P_ProviderModule has a special format.
105 The format is: <jar-file-name>:<provider-class-name>
106
107 Although jar support is not yet working correctly, this format must be used. You should use cimmofl
108 for registration untill cimmof is prepared for JMPI.
109
110 instance of PG_ProviderModule
111 {
112 Name = "JMPI_TestPropertyTypesModule";
113 Location = "JMPI_TestPropertyTypes.jar:"
114 "org/pegasus/jmpi/tests/JMPI_TestPropertyTypes/JMPI_TestPropertyTypes";
115 Vendor = "Pegasus Community";
116 Version = "2.0.0";
117 InterfaceType = "JMPI";
118 InterfaceVersion = "1.0.0";
119 };
