Hi All,
I have managed to resolve this issue with help from SAP by raising OSS incident.
Issue : While running Jload , in alertSID.log it was giving 12545 TNSLSNR error and if checked in listener log it is showing jdbc trying to connect with some junk IP.
Resolution steps: At first suspect was listener configuration for which this post was created.
After creating thread dump to analyse this issue we found that instead of actual IP ,installer is trying to connect database using junk IP. Few SAP notes 1568249 and 1841151 implemented but these were only applicable for resolving ping -4 <hostname>.
Solution provided by SAP is to disable NDIS server and lower down metric for public network card from network properties.
Regards,
Ashraf.
