Status: Geschlossen |
DB2 MAY ABEND WHEN USING DB2 TEXT EXTENDERS |
| Produkt: |
DB2 FOR LUW / DB2FORLUW / A10 - 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

| 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 > |
