(Doc ID 2325973.1)

Last updated on NOVEMBER 15, 2017

Applies to:

Oracle GoldenGate - Version 12.2.0.1.0 to 12.2.0.1.0 [Release 12.2]
Information in this document applies to any platform.

Symptoms

Collector process may receive Signal 4 repeatedly and core file is generated under following conditions.

When this problem happens, following messages appear in ggserr.log on target server.
But there is no error message in ggserr.log on source server

2017-11-06 00:51:26 INFO OGG-00974 Oracle GoldenGate Manager for Oracle, mgr.prm: Manager started collector process (Port 7819).
2017-11-06 00:51:26 INFO OGG-01228 Oracle GoldenGate Collector for Oracle: Timeout in 300 seconds.

2017-11-06 00:51:31 ERROR OGG-01668 Oracle GoldenGate Collector for Oracle: PROCESS ABENDING.

Pstack for core file has following stack info.

And due to same reason, Manager process fails to start with following errors.

GGSCI> start mgr
Manager started.

GGSCI> ld.so.1: mgr: fatal: mgr: hardware capability (CA_SUNW_HW_1) unsupported: 0x10000400 [ CBCOND VIS3 ]

This problem is resolved with following workaround.

  export LD_HWCAP=+VIS3,+CBCOND

But this workaround does not work for above problem for Collector process.

Changes

After installing OGG 12.2.0.2.
Target release of this problem is only 12.2.0.2.
