OIM 9102 Schema - OSI_CHILD_OLD_VALUE column in OSI table

Question

Hello,
OIM 9102 database schema has a table name called OSI which I think holds information about tasks.
There is a column in the OSI table called “OSI_CHILD_OLD_VALUE” (Blob type). Did anyone familiar with the content of this column? What information it contains and which use case will trigger the read on the this table column?
Thanks,

Hello,
I want to decrypt this particular column (OSI_CHILD_OLD_VALUE) value (type: CLOB). So, basically i need CLOB to byte [] - note that decrpt methods is overloaded.
My program is working for type: String - it could decrypt other encrypted OIM database fields like USR_UDF_ENCRYPTED_CUSTOM_FIELD, CUSTOM FORM FIELDS, etc...
Snippet:
ResultSet rs = stmt.executeQuery(sql);
while(rs.next()){
Clob osiClob = rs.getClob("OSI_CHILD_OLD_VALUE");
long clobLength = osiClob.length();
// I tried with below clob data extraction methods
     <extracted_value_using> = osiClob.getAsciiStream()/osiClob.getCharacterStream()/osiClob.getSubString();
byte[] decryptedVal = com.thortech.xl.crypto.tcCryptoUtil.decrypt(<extracted_value_using>,"DBSecretKey");
System.out.println("Decrypted Value -->" + decryptedVal);
Finding it pretty challenging as it is not working only for CLOB column. Any help will be appreciated.
Thanks,
