Cognos: java.lang.InvalidClassChangeError

http://www-01.ibm.com/support/docview.wss?uid=swg21504307

Problem(Abstract)

Certain malformed inputs, when sent to IBM Cognos Business Intelligence v10.1.0 URLs or parameters, can cause the JIT compiled code to crash and effectively disable IBM Cognos Business Intelligence v10.1.0.

Symptom

IBM Cognos Business Intelligence v10.1.0 becomes unresponsive and report portlets that display IBM Cognos Business Intelligence v10.1.0 data might display errors similar to java.lang.InvalidClassChangeError.

Resolving the problem

Disable the Store Sinking optimization of the JIT for both IBM Cognos Business Intelligence v10.1.0 application servers, CognosX_GW and CognosX_Disp. To disable the Store Sinking optimization, set the parameter -Xjit:disableStoreSinking in the JVM arguments for both the CognosX_GW server and the CognosX_Disp server. Use the following steps:

1. Open a WebSphere Application Server administrative console and log on as an administrative user.
2. Click Servers -> Server Types -> WebSphere Application Servers -> CognosX_GW.
3. Click Server Infrastructure -> Java and Process Management -> Process definition.
4. Click Additional Properties -> Java Virtual Machine.
5. At the beginning of the Generic JVM arguments field, before the existing arguments, enter the following value followed by a space : -Xjit:disableStoreSinking
6. Click Apply and save the configuration.
7. Restart the CognosX_GW WebSphere Application Server.
8. Repeat steps 1-7 but replace the CognosX_GW server with the CognosX_Disp server.

How to start and stop Oracle

Quoted from: http://www.thegeekstuff.com/2009/01/oracle-database-startup-and-shutdown-procedure/

log in as oracle


Connect to oracle sysdba

Make sure ORACLE_SID and ORACLE_HOME are set properly as shown below.
 $ env | grep ORA
ORACLE_SID=TESTDB
ORACLE_HOME=/opt/oracle/product/10.2.0


connect using either “/ as sysdba” or an oracle account that has DBA privilege.
 $ sqlplus '/ as sysdba'

SQL>




Start Oracle Database

The default SPFILE (server parameter file) is located under $ORACLE_HOME/dbs. Oracle will use this SPFILE during startup, if you don’t specify PFILE.

Oracle will look for the parameter file in the following order under $ORACLE_HOME/dbs. If any one of them exist, it will use that particular parameter file.
 1.spfile$ORACLE_SID.ora
 2.spfile.ora
 3.init$ORACLE_SID.ora


Type “startup” at the SQL command prompt to startup the database as shown below.
 SQL> startup

How To Shutdown Oracle Database

Following three methods are available to shutdown the oracle database:

1. Normal Shutdown
2. Shutdown Immediate
3. Shutdown Abort

1. Normal Shutdown

During normal shutdown, before the oracle database is shut down, oracle will wait for all active users to disconnect their sessions. As the parameter name (normal) suggest, use this option to shutdown the database under normal conditions.

SQL> shutdown
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL>

2. Shutdown Immediate

During immediate shutdown, before the oracle database is shut down, oracle will rollback active transaction and disconnect all active users. Use this option when there is a problem with your database and you don’t have enough time to request users to log-off.

SQL> shutdown immediate;
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL>

3. Shutdown Abort

During shutdown abort, before the oracle database is shutdown, all user sessions will be terminated immediately. Uncomitted transactions will not be rolled back. Use this option only during emergency situations when the “shutdown” and “shutdown immediate” doesn’t work.

Restricting or allowing access to the administrative console based on client IP or DNS hostname

Question

Is it possible to restrict access to the WebSphere Application Server administrative console to specific client IPs?

Answer

If a client has a requirement to allow access to the administrative console from only certain originating IPs, then it can be configured as follows.

1. Open the Deployment Manager Console to WebSphere Application Server Network Deployment (it can be the base Application Server as well) to the following:
   
   Servers > Application servers > server_name > Web container transport chains > WCInboundAdminSecure > TCP inbound channel
   
2. Under General Properties, work with the following 4 fields:
   • Address exclude list
   • Address include list (for example, 9.X.X.75, 9.55.X.X,)
   • Hostname exclude list
   • Hostname include list

Note: Multiple IPs or hostnames can be added in any of the preceding fields (as needed), but they need to be separated by a comma.

Thread dump & heap dump — Presentation Transcript

• 1. Thread dump & Heap Dump in websphere
• 2. In this session, What is Thread/Heap dump? When to generate ? How to generate ? How to debug ?
• 3. Thread Dump
  What is a Thread Dump? A thread represents a work item or task, such as a servlet request. Java processes are usually multi-threaded. This means there can be many tasks occurring simultaneously (multi-threading) within one JVM process. Java thread dumps provide a Java view of a failing JVM process. A Java dump provides information about the executing Java classes and allows the problem determination process to reference the Java source code.
• 4. When to generate
  If you get unexplained server hangs under WebSphere, you can obtain, from the WebSphere server, a thread dump to help diagnose the problem. In the case of a server hang, you can force an application to create a thread dump. If an application server spontaneously dies, look for a file. The JVM creates the file in the product directory structure, with a name like javacore[number].txt.
• 5. How to generate
  On unix/Linux machines find the process id (PID) of the hung JVM and issue kill -3 PID. Look for an output file in the installation root directory with a name like javacore.date.time.id.txt. Using wasadminprompt:get the handle of the server wsadmin>set jvm [$AdminControlcompleteObjectName type=JVM,process=server1,*] then execute wsadmin>$AdminControl invoke $jvmdumpThreads
• 6. Analysis
  Download thread analyzer from IBM website to analyze the generated thread dumps. - http://www.alphaworks.ibm.com/tech/jca
• 7. Heap Dump
  A heapdump is a snapshot of JVM memory. it shows the live objects on the heap along with references between objects. It is used to determine memory usage patterns and memory leak suspects. When to generate? Memory leaks in the Java heap produce java.lang.OutOfMemoryError exceptions in log files. However, not all out-of-memory errors are caused by Java heap memory leaks. Out-of-memory errors can also be caused by the following conditions: Java heap fragmentation. This fragmentation occurs when no contiguous chunk of free Java heap space is available from which to allocate Java objects. Various causes for this problem exist, including the presence of pinned or dosed objects or because of the repeated allocation of large objects. Memory leaks in native heap. This problem occurs when a native component, like DB2 connections, is leaking.
• 8. How to generate
  To enable automated heap dump generation support, perform the following steps in the administrative console: (heap dump will generated upon receiving the out.of.memoryexceptios) 1. Click Servers > Application servers in the administrative console navigation tree. 2. Click server_name >Runtime Performance Advisor Configuration. 3. Click the Runtime tab. 4. Select the Enable automatic heap dump collection check box. 5. Click OK. To generate manually use kill -3 PID on unix/linux machines. Using WSADMIN tool Invoke the generateHeapDump operation on a JVMMBean, for example, * Finding JVMobjectName: <wsadmin> set objectName [$AdminControlqueryNamesWebSphere:type=JVM,process=<servername>,node=<nodename>,*] * Invoking the generateHeapDump operation on JVMMBean: <wsadmin> $AdminControl invoke $objectNamegenerateHeapDump
• 9. Analysis
  heap dumps can be found under profile_rootprofile-name with naming heapdump.<date>..<timestamp><pid>.phdUse HeapAnalyzer or MDD4J for analyzing heap dumps

WAS: PCT Response file questions

Scenario 1: 4 nodes
Node 1: DeploymentManager + ApplicationServer1
Node 2: ApplicationServer2
Node 3: IHS WebServer1
Node 4: IHS WebServer2
 
Node1 and Node2 clustered.
 
Question 1: which server hostname should be for wasMachineHostName? Deployment manager server hostname? Or ApplicationServer1 hostname? Or ApplicationServer2 hostname?
ANSWER:   It does not matter which hostname.  I would probably use the hostname of the deployment manager myself.  But it really does not matter ether way.  Be sure to choose REMOTE in the PCT, and also you will want to configure the IHS Admin Server  so that you can remotely manage both IHS web servers from the WAS Admin Console.

 
Scenario 2: 2 nodes
Node 1: DeploymentManager + ApplicationServer1 +  IHS WebServer1
Node 2: ApplicationServer2 + IHS WebServer2
 
Question 1: how to decide configType value for WebServer1 and WebServer2
ANSWER:  If the web server is on the same system as the WAS appserver, then it is LOCAL.  In this case, use LOCAL for both of them.

Question 2: what should be the value of profileName for WebServer1?
ANSWER:  for LOCAL scenario, always use the profile name of the WAS node (ie. AppSrv01).  Never use the deployment manager profile name (ie. Dmgr01).

Question 3: What should be the value of wasMachineHostName for WebServer1?
ANSWER:  wasMachineHostName is only used for REMOTE scenario.  So, you do not need that variable at all in this LOCAL case.

Question 4: what should be the value of profileName for WebServer2?
ANSWER:   use the name of the WAS node profile (ie. AppSrv01).

Question 5: what should be the value of wasMachineHostName for WebServer2?
ANSWER:  this is a LOCAL scenario so wasMachineHostName is not needed.

An error has occurred:

Error Message:

    Registration failed: RHN Software Management service entitlements exhausted

Error Class Code: 91

Error Class Info: Registration token unable to entitle system: maximum membership exceeded

Explanation:

    Your organization does not have enough Management entitlements to register this

    system to Red Hat Network. Please notify your organization administrator of this error.

    You should be able to register this system after your organization frees existing

    or purchases additional entitlements. Additional entitlements may be purchased by your

    organization administrator by logging into Red Hat Network and visiting

    the 'Subscription Management' page in the 'Your RHN' section of RHN.

    A common cause of this error code is due to having mistakenly setup an

    Activation Key which is set as the universal default.  If an activation key is set

    on the account as a universal default, you can disable this key and retry to avoid

    requiring a Management entitlement.

WAS: Configure Secure File Transfer

 Configure Secure File Transfer

The filetransferSecured application shall be installed to ensure that the deployment manager only responds to file transfer requests from trusted servers in the cell, when it communicates configuration updates to node agents.

The commands to install the filetransferSecured application (if not already installed as part of default) are:

Ø              cd <profilehome>\bin

Ø              wsadmin.bat -user <wasadminuser> -password <waspassword>

Ø              wsadmin> source ../../../bin/redeployFileTransfer.jacl

Ø              wsadmin>fileTransferAuthenticationOn <your cell name> <dmgr node name> dmgr

Ø              wsadmin>$AdminConfig save

This will ensure that configuration updates are legitimate and eliminates the risk of configuration settings getting compromised.

To determine the current state of the file transfer authentication, see the systemapps.xml file in the <WAS_INSTALL_DIR>/AppServer/profiles/<PROFILE>/config/cells/cell_name/nodes/node_name directory:

·         This entry indicates that authentication is on:

<deployedApplications>${app_server_root}/

   systemApps/filetransferSecured.ear</deployedApplications>

·         This entry indicates that authentication is off:

<deployedApplications>${app_server_root}/

   systemApps/filetransfer.ear</deployedApplications>

WAS: enable JVM trace

1. Add both of the following Generic JVM Arguments in the WebSphere     
Admin Console:                                                          
                                                                        
-Xtrace:none -Xtrace:maximal=mt,methods={com/ibm/jsse2/SSLSocketImpl.<init>} -Xtrace:trigger=method{com/ibm/jsse2/SSLSocketImpl,jstacktrace} -Xtrace:stackdepth=25,output={sslsockettrace,50m} -Xdump:system:events=systhrow,filter=java/lang/OutOfMemoryError                                       
                                                                        
The use of -Xtrace:none at the beginning turns off the default Java     
trace, which can be verbose. This allows us to see the java stack traces
we want more clearly in the trace file.                                 
                                                                        
2. This setting is expected to produce a binary trace file named        
sslsockettrace. Once the OOM has been reproduced, please format the     
binary trace created from the argument above by issuing the following   
command from the WPS install root/java/bin directory. Here's an example:
                                                                        
D:/IBM/WPS/java/bin/java com.ibm.jvm.format.TraceFormat sslsockettrace  
                                                                        
3. Then send in the formatted file, which will be named:                
                                                                        
sslsockettrace.fmt

Aggregate multiple NIC’s with dladm in Solaris 10

February 24th, 2009 in COMPUTE | leave a response

ARTICLE UPDATED 05/22/2009 — Update at bottom of the page.
Likely old news to many of you, but dladm is pretty slick.
A company that I work with has some Sun X4500 boxes that they use for various tasks. The X4500, also known as Thumper, shipped with four e1000g interfaces and 24TB or 48TB of raw storage, all in a 4U 160 pound box. Though discontinued by Sun and replaced with the nicer x4540 box these old Thumpers are fine machines.
Recently I found the need to use three of the four interfaces for a larger pipe to a Cisco switch that allows port aggregation. The reasons for doing this or for using 3 ports are not really important, in your environment you might do things differently. After the box was racked and cabled the switch was configured for the ports used.
Moving on to the server, I was amazed at how simple it was to bond the three interfaces together in Solaris 10 using the dladm command.
On this hardware the devices were e1000g0 — > e1000g3:
The man page for dladm contained all I needed to get started.
First, a look at the devices. (switch ports were disabled at this time.)

root@thumper2 # dladm show-dev
e1000g0 link: down speed: 0 Mbps duplex: half
e1000g1 link: unknown speed: 0 Mbps duplex: half
e1000g2 link: unknown speed: 0 Mbps duplex: half
e1000g3 link: unknown speed: 0 Mbps duplex: half
To create an aggregate with the three devices and give it an integer as the aggregate instance the command was simply:

root@thumper2 # dladm create-aggr -d e1000g0 -d e1000g1 -d e1000g2 1
dladm: create operation failed: Device busy (invalid interface name)
root@thumper2 # ifconfig e1000g0 unplumb
root@thumper2 # dladm create-aggr -d e1000g0 -d e1000g1 -d e1000g2 1
root@thumper2 #
You can see from the output above that the devices must not be in use, e1000g0 was so the dladm command failed. That should be expected. Though e1000g0 had already been configured with an IP address, I was connected to the thumper via our Lantronix serial console. It would be unwise to unplumb the interface you came in on.
At this point ifconfig -a should not show anything (unless you have other devices or you’ve configured e1000g3, etc.).
Initially the switch ports were disabled at the Cisco, they were up for the following look at the aggregate created above.

root@thumper2 # dladm show-aggr
key: 1 (0x0001) policy: L4 address: 0:14:4f:ff:ff:ff (auto)
device address speed duplex link state
e1000g0 0:14:4f:ff:ff:ff 1000 Mbps full up attached
e1000g1 0:14:4f:ff:ff:ff 1000 Mbps full up attached
e1000g2 0:14:4f:ff:ff:ff 1000 Mbps full up attached
Your MAC addresses will not look like the modified example.
We can now see what appears to be a new device, the list shows all of the link devices. The one we are interested in is aggr1.

root@thumper2 # dladm show-link
e1000g0 type: non-vlan mtu: 1500 device: e1000g0
e1000g1 type: non-vlan mtu: 1500 device: e1000g1
e1000g2 type: non-vlan mtu: 1500 device: e1000g2
e1000g3 type: non-vlan mtu: 1500 device: e1000g3
aggr1 type: non-vlan mtu: 1500 aggregation: key 1
root@thumper2 #
All that is needed is to plumb up the interface (aggr1) and we are good to go.

root@thumper2 # ifconfig aggr1 plumb 192.168.1.2 netmask 255.255.255.0 up
root@thumper2 # ifconfig aggr1
aggr1: flags=1000843 mtu 1500 index 3
inet 192.168.1.2 netmask ffffff00 broadcast 192.168.1.255
ether 0:14:4f:fff:ff:ff
root@thumper2 #
root@thumper2 # ping thumper4
thumper4 is alive
root@thumper2 #
Make sure to rename /etc/hostname.e1000g0 to /etc/hostname.aggr1 if you want the machine to be available on the network after a reboot.
Nice, it just works!
Now to do some testing….film at 11.
Update 030909:
I forgot to mention that I’ll be trying this out with JumboFrames enabled (and disabled). To get there I’ve found better results with editing /kernel/drv/e1000g.conf then by using ndd. Same holds true for when you are forced to disable auto-negotiation and hard code the media settings. Have a look at /kernel/drv/e1000g.conf, comments in the file are sufficient.
Example entry for JumboFrames follows:
MaxFrameSize=3,3,3,3,3,3,3,3,3,3,3,3,3,3,3,3;
If you want to hardcode media/duplex e1000g you can edit /kernel/drv/e1000g.conf and reboot.
Update 052209:
After testing some zfs send / zfs rcv transfers from another thumper (using mbuffer) I decided to set LACP mode to active (both on the switch and the server).
Here is the info on how that was done.

[root@thumper2:~]# dladm modify-aggr -PL2 -l active 1
[root@thumper2:~]#
[root@thumper2:~]# dladm show-aggr -L
key: 1 (0x0001) policy: L2 address: 0:14:4f:99:99:99 (auto)
LACP mode: active LACP timer: short
device activity timeout aggregatable sync coll dist defaulted expired
e1000g0 active short yes yes yes yes no no
e1000g1 active short yes yes yes yes no no
e1000g2 active short yes yes yes yes no no
[root@thumper2:~]#
The switch involved runs CatOS and the following command is what was used there (for the ports 5/5 -> 5/7). This impacts the whole module so consider this carefully before pressing enter :)

set port lacp-channel 5/5,5/6,5/7 mode active
When time permits I’ll post some transfer times using mbuffer,rsync, etc.

Cleaning up the Operating System device tree after removing LUNs - Solaris 10 example

http://sfdoccentral.symantec.com/sf/5.0MP3/solaris/html/vxvm_admin/ch02s24s03.htm

Cleaning up the Operating System device tree after removing LUNs - Solaris 10 example

You must clean up the device tree after removing LUNs. The OS commands may vary for Solaris versions. This procedure uses Solaris 10 with Leadville stack as an example.
Contact Sun Support if any of the steps in this section fail to produce the wanted results.

To clean up the device tree after you remove LUNs

1. The removed devices show up as drive not available in the output of the format command:
   

   413. c3t5006048ACAFE4A7Cd252 <drive not available>
           /pci@1d,700000/SUNW,qlc@1,1/fp@0,0/ssd@w5006048acafe4a7c,fc

2. After the LUNs are unmapped using Array management or the command line, Solaris also displays the devices as either unusable or failing.
   

   bash-3.00# cfgadm -al -o show_SCSI_LUN | grep -i unusable
     c2::5006048acafe4a73,256   disk  connected  configured unusable
     c3::5006048acafe4a7c,255   disk  connected  configured unusable

   bash-3.00# cfgadm -al -o show_SCSI_LUN | grep -i failing
     c2::5006048acafe4a73,71    disk  connected configured  failing
     c3::5006048acafe4a7c,252   disk  connected configured  failing

3. If the removed LUNs show up as failing, you need to force a LIP on the HBA. This operation probes the targets again, so that the device shows up as unusable. Unless the device shows up as unusable, it cannot be removed from the device tree.
   

   luxadm -e forcelip /devices/pci@1d,700000/SUNW,qlc@1,1/fp@0,0:devctl

4. To remove the device from the cfgadm database, run the following commands on the HBA:
   

   cfgadm -c unconfigure -o unusable_SCSI_LUN c2::5006048acafe4a73
   cfgadm -c unconfigure -o unusable_SCSI_LUN c3::5006048acafe4a7c 

5. Repeat step 2 to verify that the LUNs have been removed.
6. Clean up the device tree. The following command removes the /dev/rdsk... links to /devices.
   

   $devfsadm -Cv

List Swap Space:
# swap -l
swapfile             dev    swaplo   blocks     free
/dev/dsk/c6t0d0s1   79,1         8  1048568  1048568

Turn off swap:
# swap -d /dev/dsk/c6t0d0s1
/dev/dsk/c6t0d0s1 was dump device --
invoking dumpadm(1M) -d swap to select new dump device
dumpadm: no swap devices are available

Notice you have no dump device
Disable swap from coming back on reboot:
#vi /etc/vfstab
there's a line to mount the swap space, remove it.. Look for your swap device, i.e. c6t0d0s1.

Add swap space (partition):
#swap -a /dev/desk/c6t0d0s1

Adding file based swap space:
#mkfile 250m /opt/myswapfile
#swap -a /opt/myswapfile
