ORA-07445[kslgetl()+120]/ORA-00108错误解决
一.数据库版本

四.在MOS上找到相关文章[ID 1298804.1]
Applies to: Oracle Server - Enterprise Edition - Version: 11.1.0.6 to 11.1.0.7 - Release: 11.1 to 11.1 Information in this document applies to any platform. Symptoms The following errors are seen in the trace file written by an ORA-7445 [kslgetl]: network error encountered getting listening address: NS Primary Error: TNS-12533: TNS:illegal ADDRESS parameters NS Secondary Error: TNS-12560: TNS:protocol adapter error NT Generic Error: TNS-00503: Illegal ADDRESS parameters OPIRIP: Uncaught error 108. Error stack: ORA-00108: failed to set up dispatcher to accept connection asynchronously Exception signal: 11 (SIGSEGV), code: 1 (Address not mapped to object), addr: 0x130, PC: [0x82f09dc, kslgetl()+80] The trace file indicates that there is no session: Current SQL information unavailable - no session. The Call Stack Trace in the ORA-7445 trace file contains a function list similar to: kslgetl <- PGOSF57_ksfglt <- kghfre <- kmnsbf <- nsbfr <- nsiofrrg <- nsiocancel <- nsopen_shutitdown <- nsclose <- nsgblclose <- nsgblTRMHelper <- nsgblRealTerm <- nlstdstp <- npinlt <- ksuabt <- opidrv <- sou2o <- opimai_real <- main <- libc_start_main Cause The trace file first reports: Warning: keltnfy call to ldmInit failed with error 46 The ORA-7445 is not the starting point here. This exception is just a spin-off from ORA-180 and it is possible that different internal errors may be seen, such as ORA-600 [504], depending on what is happening when the ORA-180 is encountered. The cause for the ORA-180 is related to the inital message at the beginning of the trace file: "keltnfy call to ldmInit failed with error 46" and this is followed by: "network error encountered getting listening address:" The error code (here: 46) is the key for solving the issue. This warning says that ldmInit() returned error 46 which is LDMERR_HOST_NOT_FOUND (host not found). This error is returned if the OS call gethostbyname() fails with an error. So these appears to be a network specific issue. Solution 1) Check permission on /etc/hosts $ ls -l /etc/hosts -rw-r--r-- 2 root root 194 Oct 17 2006 /etc/hosts Check if /etc/hosts file is correctly configured <ip address> <fully qualified hostname> <simple or short hostname> <alias, if applicable> ( all of this on one line ). 2) Check the hostname: $ hostname $ ping `hostname` Make sure you are able to ping the hostname 3) Check if /etc/nodename is correctly configured If you have DNS setup, ping is not a tool to diagnose DNS problem. A better tool to use is nslookup, dnsquery, or dig. $ nslookup <shortname> $ nslookup <long name> $ nslookup <ip address> The forward and reverse lookup should succeed and return consistent address/info. 4) Check nsswitch.conf $ more nsswitch.confhosts: files dnsMake sure host lookup is also done through the /etc/hosts file and not just dns. It is recommended that FILES come first before DNS. Also, check the resolv.conf. This makes sure that the DNS is working properly.
在这里看到虽然数据库的版本不一样,alert和trace中的错误不完全一致,但是很相似。是由于主机名不能被正常访问导致,所以尝试这从主机名相关部分着手解决。
五.查看主机名相关信息,解决问题
