Setting Environment Varibles for Java Environment

I downloaded the file j2eesdk-1_4_2005Q1-windows.exe and my installation dir is c:\sun\appserver
My Environment Varibles are setup as ...
User varibles:
CLASSPATH = .;C:\Java\jdk1.5.0_01\jre\lib;C:\Java\jdk1.5.0_01\lib;c:\sun\appserver\bin;c:\sun\appserver
PATH = C:\Sun\AppServer\bin;C:\WINDOWS;c:\java\jdk1.5.0_01\bin
System varibles:
J2EE_HOME = C:\sun\appserver\bin
JAVA_HOME = C:\Java\jdk1.5.0_01
ANT_HOME = c:\ant
I am trying to build and get the following error ...
Buildfile: C:\eclipse\workspace\sync4j-modules\pimweb\build\build.xml

Don't use your system classpath - create (say) a lib dir in your project directory, copy j2ee.jar or servlet.jar into it and have the build script reference that. See the ant documentation for path and javac.

Environment variables for Java

Hi,
I installed jdk1.6.0_02 from Sun, and set the following environment variables:
export PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/bin/X11:/usr/games:*/home/username/jdk1.6.0_02/bin*
export LD_LIBRARY_PATH=/home/username/jdk1.6.0_02/lib
export JAVA_HOME=/home/username/jdk1.6.0_0
I issue the following commands:
which javac
*/home/username/jdk1.6.0_02/bin/javac*
which java
*/usr/bin/java*
why is it referring to */usr/bin/java* instead of */home/username/jdk1.6.0_02/bin/java*
How can I solve this problem under Ubuntu 8.04.
Thank you in advance,
--Blaise

Ok */ust/bin* is needed in the PATH. Why it affected java but not javac then?
Provide an instructive solution or an instructive comment if you have.I should have thought it would have been fairly obvious that it was because javac was not in /usr/bin (and that it would have been just as easy to be certain, i.e. type "ls /usr/bin/javac"), but I guess not.
I also would have thought, that it should be fairly obvious that a search path will always be read in a specific order (after all that is one of the reasons to have one, so that command searches aren't random), and, extrapolating from there, that it should be fairly obvious, considering the problem observed, that that search order was from left to right, but again, I guess not.
Use your head for something other than a paper weight, and maybe you wouldn't need to become either defensive or aggresive, but, once again, that must be something that's beyond you.
Learn how to type "How to configure path environment variable" into Google, and maybe the same would apply, but, once again, that is probably something that's beyond you.

Skill set required for Hyperion environment patching

Hi all,
Could you please let me know what specific skill set is required for hyperion environment patching?
Does it come under hyperion application administration? Could you please also help me understand the difference between Hyperion application administrator and Hyperion infrastructure administrator?

Is there a reason for asking this question? It all depends on the company to how the role is defined, it is possbile application administrator or infrastructure administrator could be applying patches, usually falls more under an infra role though.
You would usually need product knowledge, the technologies behind EPM and the architecture, OS skills.
Cheers

Global-Cache-Manager for Multi-Environment Applications

Hi,
Within our server implementation we provide a "multi-project" environment. Each project is fully isolated from the rest of the server e.g. in terms of file-system usage, backup and other ressources. As one might expect the way to go is using a single VM with multiple BDB environments.
Obviously each JE-Environment uses its own cache. Within a our environment with dynamic numbers of active projects this causes a problem because the optimal cache configuration within a given memory frame depends on the JE-Environments in use BUT there is no way to define a global JE cache for ALL JE-Environments.
Our "plan of attack" is to implement a Global-Cache-Manager to dynamicly configure the cache sizes of all active BDB environments depending on the given global cache size.
Like Federico proposed the starting point for determining the optimal cache setting at load time will be a modification to the DbCacheSize utility so that the return value can be picked up easily, rather than printed to stdout. After that the EnvironmentMutableConfig.setCacheSize will be used to set the cache size. If there is enough Cache-RAM available we could even set a larger cache but I do not know if that really makes sense.
If Cache-Memory is getting tight loading another BDB environment means decreasing cache sizes for the already loaded environments. This is also done via EnvironmentMutableConfig.setCacheSize. Are there any timing conditions one should obey before assuming the memory is really available? To determine if there are any BDB environments that do not use their cache one could query each cache utilization using EnvironmentStats.getCacheDataBytes() and getCacheTotalBytes().
Are there any comments to this plan? Is there perhaps a better solution or even an implementation?
Do you think a global cache manager is something worth back-donating?

* Estimating JE in-memory sizes as a function of key and data size is not
* straightforward for two reasons. There is some fixed overhead for each btree
* internal node, so tree fanout and degree of node sparseness impacts memory
* consumption. In addition, JE compresses some of the internal nodes where
* possible, but compression depends on on-disk layouts.
* DbCacheSize is an aid for estimating cache sizes. To get an estimate of the
* in-memory footprint for a given database, specify the number of records and
* record characteristics and DbCacheSize will return a minimum and maximum
* estimate of the cache size required for holding the database in memory.
* If the user specifies the record's data size, the utility will return both
* values for holding just the internal nodes of the btree, and for holding the
* entire database in cache.
* Note that "cache size" is a percentage more than "btree size", to cover
* general environment resources like log buffers. Each invocation of the
* utility returns an estimate for a single database in an environment. For an
* environment with multiple databases, run the utility for each database, add
* up the btree sizes, and then add 10 percent.
* Note that the utility does not yet cover duplicate records and the API is
* subject to change release to release.
* The only required parameters are the number of records and key size.
* Data size, non-tree cache overhead, btree fanout, and other parameters
* can also be provided. For example:
* $ java DbCacheSize -records 554719 -key 16 -data 100
* Inputs: records=554719 keySize=16 dataSize=100 nodeMax=128 density=80%
* overhead=10%
*    Cache Size      Btree Size Description
*    30,547,440      27,492,696 Minimum, internal nodes only
*    41,460,720      37,314,648 Maximum, internal nodes only
*   114,371,644     102,934,480 Minimum, internal nodes and leaf nodes
*   125,284,924     112,756,432 Maximum, internal nodes and leaf nodes
* Btree levels: 3
* This says that the minimum cache size to hold only the internal nodes of the
* btree in cache is approximately 30MB. The maximum size to hold the entire
* database in cache, both internal nodes and datarecords, is 125Mb.

EWA for Java

Hi
I have setup the EWA for ABAP and now I want to setup for Java stack systems like portal and other NW systems. I have installed Wily Introscope 7.2 and now I am looking at the Root cause analysis setup guide where it says to "Activate the BI source system" - Could someone tells me why do I need to do this. Is it something to do with BI systems that we have in our landscape?
Another question is - What is the difference between the SMD agents and Introscope agents and CCMS agents?
Or could someone point me to a simple guide to setup the EWA for Java?
Thanks

where it says to "Activate the BI source system" - Could someone tells me why do I need to do this. Is it something to do with BI systems that we have in our landscape?
No.
The performance data collected through the introscope agent must be stored somewhere. SMD uses the introscope agent to collect the data. The data is not stored in flat tables but in BI cubes. This is why you need to install the BI content on the Solution Manager system. The SMD setup then activates the BI content in the SolMan. So basically BI technology is used to generate the EWAs for Java systems.
You can, however, use an existing BI system instead to store the performance data, if you have the appropriate BI_CONT patchlevel installed. Actually there are some drawbacks, it´s not yet fully automated, manual tasks have to be done to make this work.
Another question is - What is the difference between the SMD agents and Introscope agents and CCMS agents?
The SMD agent provide a "basic connection" between the SolMan and the Java system, the Wily Introscope agents instrument the functions/methods/classes and collects performance data. The CCMS agents are on a "higher layer", they can check e. g. that a specific application (e. g. the portal) is running but they can´t find out, how long a specific java method takes to be executed.
Or could someone point me to a simple guide to setup the EWA for Java?
There is no "simpler guide" for that.
Setting up EWA for Java a challenging and complex task. For us we decided that it´s not worth it because there are too many manual things to be done (profile changes which are overwritten each time you implement an SP (flightrecorder), incompatibilities of autoprobe connectors for Wily (on Linux), manual tasks need tobe done if you use an external BI system and others).
Good luck!

EWA for Java only systems

Hi,
I'm searching for a guide to set up EWAs for Java only instances. Currently I have my Java instances in SMSY as system components, but how do I set up the EWAs as only ABAP instances are selectable. I'm using the latest SP, so this functionality should be available finally. I can't find a document about that anywhere, just some very bad documented snippets in SPRO...
Regards,
Pascal

Hi Pascal,
EWA for Java systems is currently in a pilot phase. It will be released with the note 976054, which is currently still being processed internally.
Note 976054 contains a setup instruction for EWA for non-ABAP-components.
Technically, for pure Java systems the "Central SDCCN" of the Solution Manager is used as indeed pure Java systems do not have a SDCCN.
Double stack installations do not make use of the Central SDCCN, using their local SDCCN to obtain the non-ABAP data that is collected by the Diagnostics part of the Solution Manager.
The note will be released in the very near future.
Best regards,
Walter Heibey

Setting environment in Forte for java

How do i need to configure the environment in Forte for java so that i can give it
command line args with a GUI. thanks so much

Specifying Arguments for Program Execution
You can pass command-line arguments to a program's main method when you run the program.
To specify program arguments:
In the Explorer, select the runnable Java object.
From the main window, choose Build Set Arguments.
In the Set Arguments dialog box, type the arguments as if you were typing them on the command line.
If the argument includes a space, enclose it in quotation marks (for example, "arg 1").
Click OK.
You can also specify arguments on the Execution tab of the file's property inspector.

Setting Environment Varibles

Hi - Can anyone please tell me what I am doing wrong???
I downloaded jdk-1_5_0_01-windows-i586-p.exe and installed it to C:\Program Files\Java\jdk1.5.0_01 and I downloaded j2eesdk-1_4_2005Q1-windows.exe and installed it too C:\Sun\AppServer.
I am running Cygwin and the action I am attempting is giving me the following error ...
. ==================================================
. Please, set JAVA_HOME before running this script.
. ==================================================
I set my JAVA_HOME to C:\Program Files\Java\jdk1.5.0_01and

I don't know where to look for more information about Environment Varibles
I am running XP pro
It will be great if someone can help me or point me in another direction
Kind Regards

How i can set environment variable with java?

i'm tring to set it using System.setProperty("java.class.path") but it dosen't work any body help?

you will have to find out the EXACT verbage, but it's
something like this I suppose:
Runtime runtime = System.getRuntime();
runtime.exec("cmd set MY_VAR=blahhhhhhh");Yes... this creates a new process, then sets the MY_VAR environment variable for that process to "blahhhhhhh", then terminates that process.
However I think you are asking the wrong question, since your post suggests you are trying to change your classpath programatically. Ask the question you thought that was the answer to instead.

Setting persitent system environment variables using java program

hai,
Iam tryng to write installation for an application,which require to set some persistent system environment variables using java program. I have tried using set command Runtime.getRuntime().exec("cmd /c set blah blah "),but this applies only to that particular DOS promt only,i presume.And this is not perisistent.please do help.

The solution I proposed worked only on Windows XP/2003.
The following solution will work on Windows NT/2000/XP/2003 with JDK 1.2+.
1- Download the [url http://www.gjt.org/download/time/java/jnireg/registry-3.1.3.zip]JNIRegistry zipped archive.
2- Open the registry-3.1.3.zip file and extract in the folder of your choice ( Eg. c:\setenv ) only the 2 first files (when sorted by path): ICE_JNIRegistry.dll and registry.jar.
You don't need to keep the folder tree in the extraction.
3- Create the following SetEnv.java file in the same folder ( Eg. c:\setenv ).
import com.ice.jni.registry.Registry;
import com.ice.jni.registry.RegistryKey;
import com.ice.jni.registry.RegStringValue;
import com.ice.jni.registry.RegistryValue;
public class SetEnv
    static final String REG_HKLM_SUBKEY_NAME = "SYSTEM\\CurrentControlSet\\Control\\Session Manager\\Environment";
    public static void main(String[] args)
    throws Exception
        new SetEnv().exec(args);
    void exec(String[] args)
    throws Exception
        if (args.length != 2)
            throw new IllegalArgumentException("\n\nUsage: java SetEnv {varName} {varValue}\n\n");
        String varName = args[0];
        String varValue = args[1];
        RegistryKey key = null;
        RegStringValue value;
        try
            key = Registry.HKEY_LOCAL_MACHINE.openSubKey(REG_HKLM_SUBKEY_NAME, RegistryKey.ACCESS_ALL);
            value = new RegStringValue(key, varName, RegistryValue.REG_EXPAND_SZ);
            value.setData(varValue);
            key.setValue(value);
            key.flushKey();
        finally
            try { key.closeKey(); }
            catch (Exception e) {}
}4- Compile it.
javac -classpath .;registry.jar SetEnv.java
5- Run it. varName and varValue are strings of your choice.
java -classpath .;registry.jar -Djava.library.path=. SetEnv varName varValue

You can't enter sites in a list to make Firefox remember names and passwords for specific sites.
If the password manager is enabled (remember passwords is check-marked) then Firefox will ask via a pop-up from the key icon that appears on the location bar whether you want to remember that name and password and that name will then appear in the list in the password manager window.
*http://kb.mozillazine.org/Password_Manager
*https://support.mozilla.org/kb/make-firefox-remember-usernames-and-passwords
Websites can use autocomplete=off to prevent Firefox from saving the name and password.<br />
You can remove autocomplete=off with a bookmarklet to make Firefox save the name and password in such a case.
