14.10.xC2 이하 버전에서 restore 불가한 defect

안녕하세요. 14.10.xC1 과 14.10.xC2 버전의 defect를 알려드립니다. 복구가 안되는 심각한 문제입니다.

Restore with on-Bar using the Veritas™ NetBackup™ storage manager is not possible using Informix database server versions 14.10.xC1 and 14.10xC2.

Abstract

The retrieval of objects for a restore operation is not possible using certain storage managers, such as Veritas™ NetBackup™. The XBSA call BSAGetObject() fails with error 159 (0x9f).

Content

This behavior is documented as a defect in the following APAR:

IT30316 RESTORE FUNCTIONALITY IS NOT WORKING WHEN USING NETBACKUP STORAGE MANAGER

At the time of this writing, the APAR fix is scheduled in Informix database server version 14.10.xC3.  To determine whether and when the APAR is fixed and in what version it is fixed, monitor the APAR link.

If you use Veritas™ NetBackup™ with Informix database server versions 14.10.xC1 and 14.10.xC2, you need a fix for this APAR to successfully restore an Informix database server instance.  When the fix is available, customers at risk can request a special build that includes the fix or they can upgrade to the interim release that contains the fix when it becomes available.

The only known workarounds are:

1. Do not use on-Bar to archive and restore, use ontape or external archives and restores instead.
2. Use a storage manager other than Veritas™ NetBackup™ (that is, Informix Primary Storage Manager).

To confirm encountering this defect, set the onCONFIG configuration file parameter BAR_DEBUG to any number 1 - 9 and rerun the on-Bar restore.  This setting turns on extra logging in the BAR_DEBUG_LOG file.  If the following signature is encountered, the defect is confirmed:

BSAGetObject: input: bufferLen = 63488, numBytes = 0
...
BSAGetObject: output: bufferLen = 63488, numBytes = 0
BSAGetObject: return 0 (0x00)
...
barGetObjectMain: return 0 (0x00)
barGetObject: BUG!!, numbtes(0) < headerlen(4096).
barGetObject: return 159 (0x9f)

조만간 임시 수정버전이 공개될 것 같습니다. 참고되시길~
