I'm garnering comments / feedback concerning their experience around the performance and stability of FTS for global search in ITSM 7.6.04 sp2 (ARS 7.6.04 sp3) in a server group environment with a large FTS index collection.
I have an issue open with support currently where FTS plugin becomes unresponsive because it keeps running out of Java heap space. We have split the FTS indexer from the FTS searchers (per BMC support recommendations in unpublished KA363429) , so all forward facing ars servers (2 active) go against the same FTS process (we call it FTS_searcher) on the primary admin sever. So far BMC support has had us raise the Xmx from 1024 to 2048, and now to 3072. FYI - this is x64 java process on Windows 2008 x64 Each time we have bump the Xmx it runs out for memory. I was able to reproduce the rapid consumption of java memory by simply performing an incident matching search, the FTS_searcher process used up 2Gb in less than 10 seconds. Additionally, I've seen the plugin still state it was out of java heap even though the java process was no longer consuming the max Xmx defined (I'm guessing because GC ran). Looks like a lack of recovery mechanisms in place. Our FTS collection folder is 34GB in size (is that large? Above the average?), about 1.4 million incidents indexed will be the majority, plus PBIs, CRQs, RKM KAs If you have experienced similar behavior I'd love to hear your comments, but I mainly want to try and gauge from the community (with a similar setup) how stable they have seen this functionality to be. We were almost ready to go live with 7.6.04, but this is a show stopper - we can't have this instability. Regards, Andrew C.
