Problem description: | |
An UPGRADE operation involving a compressed table may hang. Additionally if you attempt to RESTORE the downlevel database backup image then this can hang as well since RESTORE will invoke an UPGRADE under the covers. If stacks are collected during the hang, one stack will show function sqldMigrateDAT() hanging in sqlbfix(), like so: 0x00002AAAB07FBE9F ossDumpStackTraceEx + 0x01ef 0x00002AAAB07F6C5E _ZN11OSSTrapFile6dumpExEmiP7siginfoPvm + 0x00cc 0x00002AAAAD89C38A sqlo_trce + 0x040a 0x00002AAAAD8E16D5 sqloDumpDiagInfoHandler + 0x00ed 0x00002AAAAACD64C0 address: 0x00002AAAAACD64C0 ; dladdress: 0x00002AAAAACC8000 ; 0x00002AAAB14EF477 semop + 0x0007 0x00002AAAAC31ACD0 _ZN17SQLO_SLATCH_CAS6418getConflictComplexEm + 0x04aa 0x00002AAAAC31A7E6 _ZN17SQLO_SLATCH_CAS6411getConflictEm + 0x0068 0x00002AAAAE5961C3 _Z7sqlbfixP11SQLB_FIX_CB + 0x1bd1 0x00002AAAABDF1E9C _Z11sqlbFixPageP11SQLB_FIX_CBiji + 0x001a 0x00002AAAACBAFFC7 _Z14sqldMigrateDATP8sqeAgentP12SQLB_POOL_CBP16SQLB_OBJECT_DESC + 0x07bd 0x00002AAAACBB1316 address: 0x00002AAAACBB1316 ; dladdress: 0x00002AAAAAEE4000 ; 0x00002AAAACBB1979 _Z22sqldMigrateTablespacesP8sqeAgent + 0x016b 0x00002AAAAC50089C _Z8sqlrliniP8sqlrr_cbb + 0x0f06 0x00002AAAAC3DC899 _Z15sqlrr_appl_initP8sqeAgentP5sqlca + 0x3107 0x00002AAAABF4984E _ZN14sqeApplication20InitEngineComponentsEcP8sqeAgentP8SQLE_BWAP 5sqlca 0x00002AAAABF4834A _ZN14sqeApplication13AppStartUsingEP8SQLE_BWAP8sqeAgentccP5sqlca Pc + 0x04fe 0x00002AAAACCA19C6 _Z8sqlemigrP8SQLE_BWAP14db2UCinterface + 0x0776 0x00002AAAABF4477E address: 0x00002AAAABF4477E ; dladdress: 0x00002AAAAAEE4000 ; | |
