Hi Team, What will be impact of below parameter if we do't set into geode cluster .
In our cluster we have 8M population with 11 VM and each VM having 5 JVM for holding the data. Means 11*5 = 55 JVM holder the CUSTOMR region. Many time face the problem , all JVM comes comes up and joined the locator . in list member I can see all members. But Command like :list REGION , assign buckets stuck in gfsh. Could you suggest what making cause to it. Currently both parameter we set to 1. net.ipv4.tcp_slow_start_after_idle 0 By default, TCP starts with a single small segment, gradually increasing it by one each time. This results in unnecessary slowness that impacts the start of every request. net.ipv4.tcp_syncookies 0 Many default Linux installations use SYN cookies to protect the system against malicious attacks that flood TCP SYN packets. The use of SYN cookies dramatically reduces network bandwidth, and can be triggered by a running Geode cluster. If your Geode cluster is otherwise protected against such attacks, disable SYN cookies to ensure that Geode network throughput is not affected. NOTE: if SYN floods are an issue and SYN cookies can't be disabled, try the following: net.ipv4.tcp_max_syn_backlog="16384" net.ipv4.tcp_synack_retries="1" net.ipv4.tcp_max_orphans="400000" https://cwiki.apache.org/confluence/display/GEODE/Network+Configuration+Best+Practices Also we set net.ipv4.tcp_abort_on_overflow = 0 .
