Semarchy xDI uses internally the java library java.util.zip.Inflater and java.util.zip.Deflater which are based on the Zlib compression for the field ACP_EXE_BLO, therefore a script action is needed.
With a scripting beanshell action called in a process, you will be able to read your BLOB_COMPRESSED table line and inflate it (decompression).
Here is a code snippet based on your environment information (Semarchy xDI 5.3.2, jdk 11 LTS) for an hardcoded action id in the table.
For any other xDI version, this code needs to be adapted. The library versions may be upgraded.

Hi Denis, can you confirm if you reproduce this issue using a query tool outside of xDI, like DBeaver or SQL developer? This seems to be a pure oracle issue that we could investigate on the internet to help you.
Yes, I can confirm that we republish with an external Oracle editor.
We would like to be able to query the Semarchy log Oracle database to extract data from the STB_LOG_ACTION_PROP_ACP table from the ACP_EXE_VAR, ACP_EXE_CLO, ACP_EXE_BLO columns. The problem is that we can't decompress the ACP_EXE_BLO field while extracting the other fields.
Thanks for your help

Hi Mickael,
Can you send us a line with INSERT SQL of your table?
In Dbeaver for example

Hello,
I need to export ACP_EXE_BLO from system log table STB_LOG_ACTION_PROP_ACP .
But this column is of type BLOB COMRESS.
I've try : utl_raw.cast_to_varchar2( dbms_lob.substr(utl_compress.lz_uncompress(ACP_EXE_BLO),2000,1))
but I get the error ORA-29294.
I need it to export logs in JSON format to THEIA
Thanks for your help

Hi Denis, can you confirm if you reproduce this issue using a query tool outside of xDI, like DBeaver or SQL developer? This seems to be a pure oracle issue that we could investigate on the internet to help you.
Please confirm your oracle version as well as there seems to be a logged bug for this function on older oracle versions : https://support.oracle.com/knowledge/Oracle%20Database%20Products/1544982_1.html

Hi Mickael,
Semarchy xDI uses internally the java library java.util.zip.Inflater and java.util.zip.Deflater which are based on the Zlib compression for the field ACP_EXE_BLO, therefore a script action is needed.
With a scripting beanshell action called in a process, you will be able to read your BLOB_COMPRESSED table line and inflate it (decompression).
Here is a code snippet based on your environment information (Semarchy xDI 5.3.2, jdk 11 LTS) for an hardcoded action id in the table.
For any other xDI version, this code needs to be adapted. The library versions may be upgraded.
Code snippet steps to publish the BLOB content in the session variable
1/ Create a process with a scripting beanshell action
2/ Action expression
