Dear Team, I am facing very strange issue in my environment and i would desperatly looking for some help.
We have recently applied below AIX patch on SAP servers and it cause the BR Offline backup to pretty slow. Vulnerability in LDAP Authentication JRE hangs when converting Java Multiple vulnerabilities in AIX BIND Sudo format string vulnerability Vulnerability in ICMP packet handling TCP network packet denial of service AIX: 6100-06-05-1115 TSM server : 5.5.6.1 Storage Agent Version: 5.5.6.0 TDP for R3 : 5.5.0.0 TSM BA Client : 5.5.3.4 BR Online backup running fine( both LAN and LAN-Free backup) BR Offline backup running fine only in LAN based backup but in LAN-Free backup it's very slow. While BR Offline backup runs, i have tested some file level backup over the storage agent and backup throughput was really good.( Transfered 22 GB of data and it took only 4 min) We have applied the AIX patches on 4 servers( 3 SAP Oracle, 1 Oracle) and all the four servers the BR Offline backups are running very slowly. I have raised the PMR but they are not ready to help at this moment( due to performance issue) Here is the one piece transfer speed.
