Have you faced these problems anytime?
1) SDM is stopped in the Windows management console but when
you execute the remote.gui the SDM GUI starts. You are puzzled!!!
2) In the logs you find that SDM cannot deploy in integrated mode ?? and now you wonder DO SDM also operates in modes???
3) SDM Out of Memory exception!!!How to solve it??
4) You forgot your SDM password! how to change it.
Lets Discuss about solutions and also the reason behind it.
MMC i.e.Windows Management console starts up SDM ,dispatcher and server0 using the Java Control Framework. Java Control Framework consists of jcontrol and jlaunch. Let me put it in this way.
JControl starts, stops, and monitors the processes of a Java instance (usually a dispatcher and several server processes). The program implements the SAP signal handling to stop the instance. JControl starts the JLaunch processes.
JLaunch starts a Java program. It loads the JVM into its own address space and then represents the required cluster element. The program can receive notification from the JControl process via named pipes to stop the cluster element, and terminates, if the JControl stops running (fork emulation under Windows)
For further reference please access the below link.
Now the Major Question is how is this going to matter SDM.
Let me explain, when SDM starts thru MMC it has to be in the Integrated mode. First let me talk about the modes so that we get more clarity about the concepts.
SDM during deploying the SDA’s and SCA’s during Installation or during patch, SDM changes its mode into standalone mode. You can see this mode details in the file
The main thing noted is that whenever SDM deploys it is in standalone mode, if you try to deploy it in integrated mode it will throw an error.
I think the problem no 2 is been answered .. 🙂
Some time while deploying some SCA’s SDM hangs or in the logs it says OutofMemory mainly in window 64 bit. It is mainly because the SDM memory is set to by default 128MB change it to 1048MB. This can be changed using the follwing command.
So you dont need to enter the old password. Saves life.
That’s all for the day, I hope this blog solve some of your problem. I will be coming up some of the blogs related to
1) JDK bug in sytem copy.
2) Discovering SLD.
3) How to interconnect CCMS,NWA and SLD.
