Question
using IBM zEnterprise Data Compression on PEGA apps running under java-7
We are trying to use zEDC tool for data compression so we are looking for some inputs on where compression takes place within the PEGA framework… some possibilities were thought to be during rules refresh, or after deleting the pega_rules marker? It seems from the logs that inflate is used a lot, which also supported in the zEDC compression accelerator (not just deflate).
any further inputs is appreciated.
Hi Marissa,
I have a question troubling me since a long time
what makes Pega Data Proprietary? is it the compression parameter set in prconfig.xml DeflateStreams to "true. -or there is some other feature that makes it properietary
Can somebody please answer this urgently?
If we do not compress the data-does it mean 3rd party technologies like Golden Gate and Data Guard would be moving data in a non proprietary zone
what is the percentage of compression that pega achieves as a result of this compression
What are the concerns if we do not compress using Pega feature but do it at the database level?

I am adding this to clarify the question as I am interested in the potential CPU offload, and performance boost this may provide.
Section 8.1 / pg 143 in this redbook: http://www.redbooks.ibm.com/redbooks/pdfs/sg248259.pdf explains the Java specific methods eligible for zEDC hardware assistance. Specific code examples are provided. Essentially the question of where does Pega perform deflate/inflate (stowing LOBs?, passivation in filesystem?) and if so, are the default buffers sizes large enough (4k min) to be eligible for hardware offload. If Pega defaults do not meet min buffer size requirements, can they be set via a property?
Hi Aarin,
I reached out to some of our Subject Matter Experts and we have some questions that we hope can clarify for us what you are trying to do.
Hoping that if you can provide clarity to those questions, the moderation team will be able to assist you further in getting a helpful reply.
Thanks in advance!
