This flash alert is meant to inform you of a IBM Rational ClearCase MultiSite defect which causes packet imports to fail with a warning, Cannot read header of packet. The issue occurs when attempting to synchronize a packet between a 8.0.0.x VOB server and a 7.1.2.x VOB server (either direction) where the VOB family feature level is 6.
A ClearCase 8.0.0 VOB server that is hosting a Feature Level 6 VOB replica is unable to import packets for that replica generated on a 7.1.2 VOB server, and generates export packets from that replica that are not readable (can not be imported) by a 7.1.2 VOB server.
Packet imports fail with warning message:
multitool: Warning: Cannot read header of packet
23T095226+0200_2316: Invalid argument
multitool: Error: File
23T095228+0200_8428 is not a sync. packet
Defect APAR PM71680 has been opened to address this issue.
Note: VOB Feature Level 6 was introduced with IBM Rational ClearCase 126.96.36.199. See About feature levels and ClearCase for further details.
- If you have your VOBs at Feature Level 6 and are considering an upgrade to ClearCase 8.0, you should delay the upgrade until a fix is available for this defect.
- If you have some sites upgraded to 8.0.0 already, but not all, and are considering raising the feature level to 6 (not 7), you should delay the feature level upgrade until a fix is available for this defect.
