Avoid overwriting the Db2 special registers

When Instana performs transaction tracking for Db2 processing, the Db2 special register CLIENT_WRKSTNNAME was overwritten with Instana's TraceID.

Many customers set their own values in Db2 special registers to aggregate data by transaction type.

Specifically, the following three special registers are output to the Db2 Accounting Trace, making the user-defined information critical and undesirable to overwrite. Please improve the Db2 transaction tracking process to avoid overwriting the following Db2 special registers.

•CLIENT_USERID (Accounting Trace:ENDUSER)

•CLIENT_APPLNAME (Accounting Trace:TRANSACT)

•CLIENT_WRKSTNNAME (Accounting Trace:WSNAME)
