Affected Products and Versions
| Affected Product(s) | Version(s) |
| IBM Tivoli Application Dependency Discovery Manager | 7.3.0.0 - 7.3.0.8 |
Remediation/Fixes
Check java version installed on TADDM servers using the below command:
$COLLATION_HOME/external/<jdk- folder according to OS>/bin/java -version
- For TADDM 7.3.0.5 - 7.3.0.8 (JAVA 8), if the above command output contains "SR6 FP10" or "8.0.6.10" or any version greater (SR6FP15 or 8.0.6.15) , as build in Java(TM) SE Runtime Environment information, apply efix for the new IBM SDK only, efix_psirt_jdk8.0.6.20_FP8201126.zip given in Table-1 below.
- For TADDM 7.3.0.3 - 7.3.0.4 (JAVA 7), if the above command output contains "SR10 FP65" or "7.0.10.65" as build in Java(TM) SE Runtime Environment information, apply efix for the new IBM SDK only, efix_jdk7.0.10.75_FP420171214.zip given in Table-1 below.
- For all other cases,
The remediation consists of 2 steps:
- Please contact IBM Support and open a case for a custom version of eFix: For TADDM 7.3.0.5 - 7.3.0.8 (JAVA 8), request for efix "customJDK8.0.6.10" and For TADDM 7.3.0.3 - 7.3.0.4 (JAVA 7), request for efix "customJDK7.0.10.65", as this efix involves TADDM code changes. Include the current eFix level (ls -rlt etc/efix*), TADDM version and a link to this bulletin.
- Alongwith the above efix, apply efix for the new IBM SDK as per TADDM version given in Table -1 below.
Table-1:
Please get familiar with the eFix readme in etc/efix_readme.txt. These fixes for the respective FixPack(s) can be downloaded and applied directly.
