Documentum : Unexplained DM_API_E_EXIST Error, client_pcaching_change

12

posted by                filed under DEVELOPMENT, Documentum, DQL DCTM, TOOLS DCTM

Hello,

I would like to explain information concerning an error with the message DM_API_E_EXIST with stacktraces below. The system could not retrieve the objects while they were present in the docbase, suggesting a problem of corruption or consistency.

First, in Documentum, there are several levels of cache : Object type caching (cache of object type definitions), Repository session caches (existing only for the life of the repository session), Persistent caching…etc.
See Caching chapter in “Documentum Content Server Fundamentals” documentation :
http://www.jouvinio.net/wiki/images/c/c2/Documentum_Content_Server_6.7_Fundamentals.pdf or this other resource : http://pingfang.iteye.com/blog/869589

Secondly, after some research on the net, it seems that the concern comes from the persistent cache at the DFC level. The first test was to change the value of the I_VSTAMP field on the DM_SYSOBJECT_S table for one of the documents concerned by the problem. After incrementing the value of 1, the problem in client application no longer appeared for the document. Obviously this change forces DFC to flush the persistent cache for this object.
Obviously, a change on this property forces DFC to flush out all persistent caches of any kind, and this for any new open sessions from the change.

More, there is client_pcaching_change property which controls whether the persistent caches, including the object caches and all query caches, are flushed when a client session is started. When a client session is started, the DFC checks the cached value of the client_pcaching_change property against the repository value. If the values are different, the DFC flushes all the persistent caches, including the object caches and all query caches.The client_pcaching_change value must be changed in the docbase config object manually, by a Superuser.

Java : Web Service : Tracing XML requests/responses with JAX-WS

posted by                filed under Java

Hi,
Following options enable logging of all communication to the console. Set these options in the code, as command line parameter using -D or as environment variable:

	static {
		// 
		System.setProperty("com.sun.xml.ws.transport.http.client.HttpTransportPipe.dump", "true");
		System.setProperty("com.sun.xml.internal.ws.transport.http.client.HttpTransportPipe.dump", "true");
		System.setProperty("com.sun.xml.ws.transport.http.HttpAdapter.dump", "true");
		System.setProperty("com.sun.xml.internal.ws.transport.http.HttpAdapter.dump", "true");


		//System.setProperty("javax.net.ssl.trustStore", System.getProperty("user.dir") + "\\mycertificates");
		//System.setProperty("javax.net.ssl.trustStorePassword", "JavaLu");
		//System.setProperty("javax.net.ssl.keyStore", System.getProperty("user.dir") + "\\mycertificates");
		//System.setProperty("javax.net.ssl.keyStorePassword", "JavaLu");

	}

Documentum : Execution CMD/PowerShell Via Job/Method

13
Jul
posted by                filed under DEVELOPMENT, Documentum, Java, Tools

Hello,

Sometimes, the execution of a job/method Documentum via Java Method Server (JMS) can generate a Core dump error for various reasons : content file protected, document corrupted, …etc…especially when using IRM protection which produces the stopping of DCTM job.

Here, an example of error:

	EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x00000000111b9d09, pid=3684, tid=7584
	#
	# JRE version: 7.0_17-b02
	# Java VM: Java HotSpot(TM) 64-Bit Server VM (23.7-b01 mixed mode windows-amd64 compressed oops)
	# Problematic frame:
	# C  [libemcdctmirm.dll+0x1f9d09]  PVS_TemplateListFree+0x7069
	#
	# Core dump written. Default location: D:\App\Workspaces\....\hs_err_pid3684.mdmp

So, I will try to expose a simple solution in order to avoid the stopping of JMS by by-passing the use of JMS:
DCTM JOB => DCTM METHOD => Script BATCH CMD => Script POWERSHELL => JAVA DFC/JVM

  • Creation of a DCTM job My_Method_PowershellScript :
    In Documentum Administrator, in the section Administration/Job Management/Methods, create a method My_Method_PowershellScript:

    ***** in tab "Method Info" 
* Name = My_Method_PowershellScript
* Verb = D:\App\MyFolder4DCTM\My_ScriptProcess.cmd
* Method Type = program
* Timeout Minimum = 30
* Timeout Default = 172800
* Timeout Maximum = 345600
* Launch Direct	= [X] Use the exec call to execute the procedure
* Launch Asynchronously	= [X] Launch as a separate process	 
* Run As Owner = [X] Run as the installation owner
  • Creation of a DCTM method My_Job_BatchScript :
    In Documentum Administrator, in the section Administration/Job Management/Jobs, create a method My_Job_BatchScript:

    ***** in tab "Info"
* Name = My_Job_BatchScript
* Trace Level = 0 (no trace)
* Designated Server = Any Running Server
* State = "Inactive"

***** in tab "Method"
* Method Name = My_Method_PowershellScript

***** in tab "SysObject Info"
* Title = My_Job_BatchScript
  • Creation of folder containing the scripts and librairies D:\App\MyFolder4DCTM on DCTM server
  • Creation of BATCH CMD script My_ScriptProcess.cmd in the folder D:\App\MyFolder4DCTM calling the POWERSHELL script:

  • So, on the DCTM server, in the folder D:\App\MyFolder4DCTM, there will be:
    o My_ScriptProcess.cmd
    o My_ScriptProcess.ps1
    o MyJavaLuLib.jar : containing all needed classes
    o \lib : commons-collections-3.2.jar + commons-configuration-1.5.jar + commons-io-1.2.jar + commons-logging-1.1.1.jar + ojdbc6.jar + commons-csv-1.1.jar …etc.
    o \dfc : all JARs and DLLs of DFC (dfc.jar,Dfc.dll, …etc).
    o \log : log files

Just a last point, in the POWERSHELL script the below command allows debugging of remote server execution from local IDE (Composer) via the port 9797:
“-Xrunjdwp:transport=dt_socket,address=9797,server=y,suspend=y”
however, if this instruction is uncommented, the execution is put on hold until the launch of the IDE on the port.

SAMBA JCIFS : Open Source library for CIFS/SMB networking

posted by                filed under DEVELOPMENT, Java, Libray

Hi,

Here, a simple example using the Samba Java CIFS Client Library. JCIFS is an Open Source client library that implements the CIFS/SMB networking protocol in 100% Java. CIFS is the standard file sharing protocol on the Microsoft Windows platform (e.g. Map Network Drive …). This client is used extensively in production on large Intranets.
