Datastage server crashed on failover to secondary server
Posted: Tue May 08, 2018 12:27 pm
Hi,
We have IIS 11.5 is installed on active / passive cluster (Power HA Version 7). When the application fails over to secondary host, and engine starts up more than 45k DB connections are opened to XMETA (sample below) and server crashes due to memory spike to 100% and swap to 99%. The application comes up fine on the primary host and we dont have that many internal connections and it is stable. All the tiers are installed on one single host.
tcp4 0 0 iis-uat.db2c_db2 iis-uat.33010 ESTABLISHED
tcp 0 0 iis-uat.33010 iis-uat.db2c_db2 ESTABLISHED
tcp4 0 0 iis-uat.db2c_db2 iis-uat.33013 ESTABLISHED
tcp 0 0 iis-uat.33013 iis-uat.db2c_db2 ESTABLISHED
tcp4 0 0 iis-uat.db2c_db2 iis-uat.33016 ESTABLISHED
tcp 0 0 iis-uat.33016 iis-uat.db2c_db2 ESTABLISHED
Would be great if someone could help. Appreciate it.
