We have a very old PeopleSoft HR system running on DB2 8.x. Numerous times a day we get the following errors in the db2diag.log file.
2019-11-04-01.22.24.012784-300 E16054C794 LEVEL: Error (OS) PID : 229596 TID : 772 PROC : db2hmon 0 INSTANCE: hrprod NODE : 000 FUNCTION: DB2 UDB, oper system services, sqloPdbConnectSocket, probe:20 MESSAGE : ZRC=0x810F0019=-2129723367=SQLO_CONN_REFUSED "Connection refused" CALLED : OS, -, connect OSERR : ECONNREFUSED (79) "Connection refused" DATA #1 : String, 32 bytes Unable to connect socket on path DATA #2 : socket, 4 bytes 7 DATA #3 : sockaddr, 39 bytes 0x303B4F38 : 0001 2F75 7372 2F75 7365 7273 2F64 6232 ../usr/users/db2 0x303B4F48 : 6173 2F64 6173 2F74 6D70 2F64 6173 6E61 as/das/tmp/dasna 0x303B4F58 : 6D65 6470 6970 65 medpipe DATA #4 : File name, 37 bytes /usr/users/db2as/das/tmp/dasnamedpipe
We're not sure what's causing the error but the reference to DAS in the error has me thinking the instance is trying to connect to the DAS server, or maybe the other way around. The DBA who was responsible for the system said the error has appeared for a long time and he couldn't figure out the cause but it had no noticeable negative implications on functionality. He retired last week. I'd like to fix the issue if possible. I'm not familiar with 8.4 and it's use of DAS other than DAS being needed to administer multiple instances, using a GUI, on the same server (there's only one instance on the server).
Any help tracking this down greatly appreciated. :)
