Enabling pin_virtual_time first time after BRM 7.4 installation

During development many times we need pin_virtual_time utility to move the BRM time forward to test many scenarios like billing, invoicing, dunning et.c.
After installing the BRM 7.4 components in the server, generally the pin_virtual_time_file is not created and also the entry is commented in almost all the component's pin.conf file.
Here are some tips to enable the pin_virtual_time (may be useful to novice BRM developers/testers)

1). Uncomment pin_virtual_time entry in all the components' pin.conf file. You may run the following command :
find  $PIN_HOME/ -name "pin.conf" | xargs sed -i 's/# - - pin_virtual_time/- - pin_virtual_time/g'
2). Restart the BRM server
3). Goto the $PIN_HOME/sys/test directory and execute
    $> pin_virtual_time
    This will create the pin_virtual_time_file and from now on you can move the time.

PIN_VIRTUAL_TIME USAGE
usage: pin_virtual_time [-h|-H|-?] [-f filename] [-m mode [value]]|[-i interval]
    -h, -H, -? print this message.
    -m ... set pin_virtual_time to mode, nothing or -i query pin_virtual_time
    mode is 0 (regular), 1 (fixed) or 2 (running)
    value as [mmdd]HHMM[[cc]yy][.SS]
    interval is time between queries in seconds

Search flist to find billinfo and account poid using account_no

Following is a complex search flist for finding BILLINFO poid and ACCOUNT poid using the ACCOUNT_NO field. As such this is used while running the bill utility during test runs but consider it as a sample for searching and extracting field values from two different storable class in single search. Generally, using a simple flist this is not achievable.

0 PIN_FLD_POID                      POID [0] 0.0.0.1 /search -1 0
0 PIN_FLD_FLAGS                      INT [0] 768
0 PIN_FLD_TEMPLATE                   STR [0] " select X from /account 1, /billinfo 2 where 1.F1 = 2.F2 and 1.F3 = V3 "
0 PIN_FLD_RESULTS                  ARRAY [*] allocated 2, used 2
1     PIN_FLD_POID                  POID [0] NULL
1     PIN_FLD_LINKED_OBJ           ARRAY [2] allocated 3, used 3
2         PIN_FLD_ACCOUNT_OBJ       POID [0] NULL
2         PIN_FLD_LINK_DIRECTION    ENUM [0] 1
2         PIN_FLD_EXTRA_RESULTS    ARRAY [*] allocated 1, used 1
3             PIN_FLD_POID          POID [0] NULL
0 PIN_FLD_ARGS                     ARRAY [1] allocated 1, used 1
1     PIN_FLD_POID                  POID [0] NULL
0 PIN_FLD_ARGS                     ARRAY [2] allocated 1, used 1
1     PIN_FLD_ACCOUNT_OBJ           POID [0] NULL
0 PIN_FLD_ARGS                     ARRAY [3] allocated 1, used 1
1     PIN_FLD_ACCOUNT_NO             STR [0] "0.0.0.1-90356"

I will provide the explaination shortly.
