UCMDB Load Management

As our ucmdb environment grow, more and more user are accessing and utilizing our ucmdb.

 

What is the best practice for load management?

 

I couldnt find anything related to load management, only high availability in the guide.

 

 

Thank you,

Re: UCMDB Load Management

Few things that comes in my mind to manage the load are as follows


1.Try to increase the RAM and Cores as much as possible for the UCMDB, DB and DDMA Server


2.Keep Scheduling the Enrichments, Report generation and Discovery Jobs on the Off - peak time


3.Clear the Logs very frequently may be i would suggest weekly once or twice

Re: UCMDB Load Management

I'm not sure how logs clening could affect performance, since UCMDB using standard Log4J with log rotating mechanism.

What for sure, you need to check that any havy logs (like dal, reconciliation, autodiscovery) aren't in DEBUG.

Check DB guide. There are some specific DB configuration that could significal improve performance.

In addition, I'd like to stay on latest code base where possible. Performance is one of biggest chalenges for systems like UCMDB. Latest cumulative update packages (AKA CUPs) will bring you performance patches among other bug fixes.

Re: UCMDB Load Management

We alway try to stay on the latest CUP (currenlt CUP8).

Our environment is on a 32gb 24 processor box. I'm using the following setting:

# Initial Java Heap Size (in MB (Xms))
wrapper.java.initmemory=4096

# Maximum Java Heap Size (in MB (Xmx))
wrapper.java.maxmemory=16384

wrapper.java.additional.31=-XX:MaxPermSize=512m
# set MaxNewSize explicitly, otherwise VM sets some default numbers
wrapper.java.additional.32=-XX:MaxNewSize=2048m
wrapper.java.additional.33=-XX:+UseCompressedOops

Our UCMDB never really go past 6GB, even with more and more people using it. But we can notice the performance degrading as more people are in it.

Any change to the above setting recommended?

Re: UCMDB Load Management

Looks good.

Check that your DB is alligned with DB guide performance guidelines.
