DB2 MAY ABEND WHEN USING DB2 TEXT EXTENDERS | |
Produkt: | |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 | |
Problembeschreibung: | |
A rare timing condition involving loading/unloading of the DB2 client library when using DB2 text extenders may cause a DB2 instance to shutdown abnormally (trap). The trap symptoms may vary and are similar to memory corruption. Examples: _getpwnam_shadow_r _posix_getpwnam_shadow_r osshomepath.getpwnam_r ossBuildHomeDirectoryRelativePath GlobalReg.GetGlobalRegPathnameInternal GlobalReg::init GlobalReg::GlobalReg ossOpenInstanceList EnvRegRefresh EnvRegOpen sqloPRegQueryDefaultValue EnvGetDB2SysVar EnvQueryDB2SystemVariables sqloInitEnvironment .sqloAppLibInit mod_init1 usl_init_mods uload load1 load loadAndInit dlopen sqloAIXLoadModuleTryShr sqloLoadModule sqlerLibraryLoad .sqlerRoutineLoad .sqlriOneTimeInitRtn1Trusted sqlriOneTimeInitRtn ... sqleAddToFreeCtxList sqleFreeTrustedCtxInternal sqleUCtrustedRtnTerm sqlerLibraryTrueUnload sqlerLibraryUnloadAll sqlri_close_udf_eog sqlrr_appl_term ... | |

Local-Fix: | |
A workaround is to invoke a trusted routine over a persistent connection. This will keep the client library loaded in the db2 server process, thus avoiding the timing condition. db2 connect to <database> db2 "values dayofyear(current timestamp)" < leave this connection open continuously > | |
